The disclosure relates to the technical field of medical device, and more particularly to a structure of an injection and infusion pump.
Generally, in clinical treatment, injection pump and infusion pump are used together, such as be stacked on each other. Some high-end injection and infusion pumps (injection pump and infusion pump) have display screens to display more information. However, due to the increasingly tight space in medical places such as wards and surgical rooms, the compactness requirements for the injection and infusion pump are getting higher and higher. Therefore, the volume of existing injection and infusion pump is generally small. In addition, the existing injection and infusion pump generally adopts the design of small square display screen together with physical keys. Therefore, there is less information displayed on the injection and infusion pump, which is not conducive to viewing more information on the same screen. Moreover, the injection pump should use the syringe to inject. However, the pump door of the existing injection pump blocks an end of the syringe, where the liquid outlet of the syringe locates. During the infusion process, the nurse cannot see the remaining amount of drug in the syringe at the end of the syringe, where the liquid outlet of the syringe locates, resulting in frequent manual opening of the pump door to confirm the remaining amount of drug and to help confirming the time for change or renewal of drug. Moreover, the existing injection pump always has the problems, such as when the syringe and extension pipe fall off and the liquid drug leaks out, the doctor cannot know and find it in time, in clinical treatment.

An embodiment of the present disclosure has provided an injection pump. Referring
The pump body 110 is provided with an installation structure 1111 which is operable to install a syringe 300. For example, a syringe canister of the syringe 300 is fixed at a certain position by a clamping structure. The installation structure 1111 includes but is not limited to a clamping structure, a magnetic adsorption structure, a snap structure, a tight-fitting structure, etc. The drive device is operable to bring a piston rod of the syringe 300 to move to inject liquid. For example, the piston rod of the syringe 300 is pushed by a push rod 141 shown in the drawing to move. Among them, the drive device can usually use a motor as the power source element. The motor converts a rotation motion into a linear motion through a transmission mechanism (such as a lead screw, nut transmission mechanism), so as to push the piston rod of the syringe 300 to move and squeeze the liquid in the syringe 300. In working principle, the injection action of the injection pump 100 is implemented as follows. The single chip system sends out a control pulse to rotate the motor through a drive circuit. The motor drives the screw rod and nut through a deceleration mechanism to convert the rotation motion of the motor into a linear motion of the nut. The nut is connected with the push rod 141 of the syringe 300 which is matched with the nut itself, that is, the nut can push the piston rod of the syringe 300 which is matched with the nut itself for liquid injection and infusion. By setting a rotation speed of the motor, a push speed of the motor that is applied to the matched syringe 300 can be adjusted, such that an injection dose and speed of the given drug can be adjusted. Of course, in addition to the motor, the drive device can also use a power source element such as a cylinder that can output a linear motion.
The control unit is operable to control the drive device. The control unit may include a processor and a peripheral device interface. The processor can be operable to send an instruction to the drive device. The peripheral device interface can be connected with a peripheral device such as physical key 120 for signal transmission, so that the processor can control the drive device according to the wish of the user.
The control unit is electrically connected with the physical key 120 for the user to input an instruction. Wherein the physical key 120 includes at least one of a power key, an emergency stop key, a main menu key, a screen unlocking key and a pump door unlocking key. The physical key 120 can control the processor through a bus and peripheral device interface. Specifically, the power key is connected with the control unit. By pressing the power key, the control unit is driven to send a control signal to a power system to power on or off the injection pump. Specifically, the emergency stop key is connected with the control unit. By pressing the emergency stop key, the control unit is driven to send a control signal to the drive device to move or stop the drive device of the injection pump. Specifically, the main menu key is connected with the control unit. By pressing the main menu key, the control unit is driven to send a control signal to a display screen control chip for displaying a main injection and infusion interface on a display screen. Specifically, the screen unlocking key is connected with the control unit. By pressing the screen unlocking key, the control unit is driven to send a control signal to a touch-control screen control chip, for activating or deactivating a preset touch-control function or a touch area on a touch-control screen. Specifically, the pump door unlocking key is connected with the control unit. By pressing the pump door unlocking key, the control unit is driven to send a control signal to a pump door switch mechanism for opening or closing the pump door.
The pump door 130 is movably installed on the pump body 110 to shield and un-shield the syringe 300 which is installed on the pump body 110, so as to prevent the syringe 300 from being touched by foreign objects during the operation of the injection pump 100, thus preventing the injection operation from being affected. Referring to
Wherein the pump door 130 includes a door body 131, a transparent window 133 and a screen assembly 132. The screen assembly 132 is connected with the control unit (such as the processor), so that it can display specified information under the control of the control unit. At the same time, the screen assembly 132 can also input instructions and information to the control unit through a touch-control manner. The screen assembly 132 has a display area 1321 which is capable of displaying information. Wherein at least a part of the display area 1321 has a touch-control function, that is, at least a part area of the screen assembly 132 is a touch-control display screen which can be connected with the control unit to display information and receive a touch-control instruction of the user. The non-touch-control area of the display area 1321 may only be used for displaying, so it can use an ordinary display screen.
At least a part of the display area 1321 of the screen assembly 132 has a touch-control function. In this way, some physical keys 120 which are used for inputting instructions can be omitted. For example, only important keys, such as the power key 121, emergency stop key 122, etc. can be remained. In this way, the display area 1321 can be larger, so more information can be displayed, so it is more convenient for the user to view.
Referring to
In this embodiment, the display area 1321 has a roughly elongated shape. Due to the reduction of the original physical key 120 and the full use of the flat shape of the injection pump 100, the surface area of the display area 1321 is greatly enlarged, so that more information can be displayed for the user to view.
In the injection pump 100 according to some of the above embodiments, the display area 1321 of the screen assembly 132 has a width which is greater than or equal to 70% of a width of the front surface of the pump door 130. Since the width of the injection pump 100 is usually greater than its height, the space in the width direction of the injection pump 100 can be sufficiently used to form a display area 1321 which has a roughly elongated shape and such display area 1321 is larger than the display area of the existing product. Thus, the display area 1321 is larger and more information can be displayed, so it is more convenient for the user to view. Herein, the “width” refers to a distance between the left side and the right side of the injection pump 100, in a normal use state. The “height” refers to a distance between the top side and bottom side in the vertical direction of the injection pump 100, in a normal use state.
Of course, in a certain embodiment, the display area 1321 of the screen assembly 132 has a width which is greater than or equal to 70% of a width of the front surface of the pump door 130, and meanwhile the display area 1321 of the screen assembly 132 extends from a left side of a center line of the front surface of the pump door 130 to a right side of the center line of the front surface of the pump door 130. In such a way, the surface area of the display area 1321 of the screen assembly 132 is further enlarged.
Further, please refer to
Of course, the injection pump 100 can also include other components, such as a motor drive system, storage system, sensing and monitoring system and alarm system, which will not be described herein.
Referring to
The clamping mechanism includes a clamping block and an elastic member (such as a spring, shrapnel, etc.) that drives the clamping block to move in a direction for releasing the syringe 300. The clamping block can be movably installed on the pump body 110, on which a syringe placement position is arranged. The syringe 300 is placed on the syringe placement position. The clamping block is positioned inside the pump door 130 and on a movement path of the pump door 130 when the pump door 130 is closed. When the pump door 130 is closed, the pump door 130 pushes the clamping mechanism to clamp the syringe 300 and prevent it from moving. When the pump door 130 is opened, the clamping mechanism is restored to release the syringe 300 as it lost the support of the pump door 130, so that the user can take and place the syringe 300.
As the installation structure 1111 is positioned inside the pump door 130, the outer space of the pump door 130 is released, so that there is more space on the front surface of the pump door 130 to install the screen assembly 132, which is also conducive to arrange the display area 1321 of the screen assembly 132 larger enough.
Further, referring to
In one embodiment, at least a part of the display area 1321 of the screen assembly has a touch-control function, and information or instructions inputted by the user through the touch-control mode are displayed on the display area 1321 in real time. Referring to
Preferably, in one embodiment, a surface area of the display area 1321 of the screen assembly 132 is greater than or equal to ⅔ of a surface area of the front surface of the pump door 130. In this way, there can be a larger display area 1321 and touch-control area 1321a (that is, the part of the display area 1321 with the touch-control function).
In another embodiment, the entire display area 1321 of the screen assembly 132 is a touch-control display screen with both information display function and touch-control function. The touch-control display screen can be realized by various screen assemblies that can not only realize the information display function, but also can realize the touch-control function. The entire touch-control screen can be used as the touch-control area 1321a, which can not only display more information, but also enlarge the operation space of the user and greatly improve the convenience of use.
Furthermore, the transparent window 133 is operable to enable the user to easily observe a situation of the pump door 130. Generally, it is mainly for the user to observe the end of the syringe 300, wherein the liquid outlet of the syringe 300 locates. Referring to
The positions of the transparent window 133 and the screen assembly 132 can be flexibly arranged according to the position of the syringe 300. Please refer to
Please refer to
When the transparent window 133 is positioned below the screen assembly 132, as shown in
As shown in
Further, as shown in
Further, in order to ensure the sealing performance, please refer to
Referring to
As a scheme with low cost but good sealing effect, in one embodiment, the transparent window 133 is made of transparent plastic, the transparent window 133 and the frame 1311 together form an integrated structure through a two-color injection molding process, and the screen assembly 132 is fixed and sealed with the support beam 1312 and the transparent window 133 by adhesive.
Please refer to
After the screen assembly 132 and the transparent window 133 are jointed, they form an entire structure together with the door body 131. The entire structure can be moved as a whole and can be loaded and unloaded as a whole on the pump body 110. This is very convenient.
The screen assembly 132 may have a large screen (for example, an integral touch-control display). In addition, please refer to
In some embodiments, at least one of these small screens can be selected as an ordinary display screen for displaying information only, and at least one of these small screens can be selected as a touch-control display screen that can display information and realize a touch-control function. Under the combination of these small screens, both display and touch-control functions can be completed. For example, some small screens can be used as the aforementioned real-time display area 1321b, and some small screens can be used as the aforementioned touch-control area 1321a.
Further, referring to
In this regard, in this embodiment, a send terminal and a receive terminal of the display screen 1324 are integrated on one display control chip, which reduces the number of the display control chips and reduces the assembly space required for the display control chips and the touch-control chips. Furthermore, referring to
This structure can release the upper area 1322b-1, the lower area 1322b-2 and the second side area 1322b-4 of the opaque area 1322b in the outer panel 1322. And the width of at least one of the upper area 1322b-1, the lower area 1322b-2 and the second side area 1322b-4 of the opaque area 1322b can be reduced (the size as shown in the directions B, C and D in
In this way, the display area 1321 of the screen assembly 132 can be as close to an outer edge of the opaque area 1322b on the upper and lower sides as possible, so as to realize the effect of narrow frame. This structure makes full use of the width of the pump door 130 and further improves the height of the display area 1321 of the screen assembly 132 without changing the volume of the pump door 130. Based on this structure, in one embodiment, the width of the area, where the control chip is not arranged, in the opaque area 1322b, such as the width of the upper area 1322b-1, the lower area 1322b-2 and the second side area 1322b-4, can be arranged to 2-4 mm at least, such as 3.3 mm.
Furthermore, in one embodiment, a screen test interface is arranged on the back surface of the first side area 1322b-3. Wherein the screen test interface is connected with the display control chip and the touch-control chip. Among them, the display control chip, touch-control chip and screen test interface are arranged on the same side, which is convenient for outgoing line. The space of the screen test interface on single side can be less than 12 mm, preferably 6 mm, so as to reduce the space that is occupied by the screen test interface. At the same time, the space occupied by the non-display area 1321 above and below the opaque area 1322b is the smallest, so that the upper and lower sides of the opaque area 1322b are extremely narrow, such as less than 40 mm.
This embodiment uses a monolithic integrated chip, which is placed on the side and integrates the drive terminal and the receive terminal. Moreover, in this embodiment, the test interface is arranged on one side, and the width of the test interface is arranged to be less than 12 mm. Based on this structure, when using the scheme shown in the above embodiment, the display 1324 can generally adopt the COG process with lower cost, that is, the chip on glass process, which can reduce the cost and satisfy the requirements of narrow frame and overall coordination.
Please continue to refer to
The display control chip has one interface cable 1325a, and the touch-control chip has one interface cable 1325b. The two interface cables are integrated into an integrated interface 1325 which integrates display and touch functions, so there is no need to arrange their own interfaces separately.
In order not to occupy more space of the first side area 1322b-3, please refer to
In one embodiment, the size of the display area 1321 is 7 inches, so that more information can be displayed for the user to view.
In one embodiment, when the display area 1321 is enlarged, in order to ensure the display quality, in one embodiment, the screen resolution of the display 1324 is not less than 960*272.
In order to make full use of the feature that the length of the pump door is larger than its width, in one embodiment, the length of the display area 1321 is larger than its width for more than 5 times, for example, its length-width ratio is 6:1.

Please continue to refer to
As the touch control screen itself is made of glass, it is complicated to add physical keys 120 to the screen. Therefore, generally, the keys of the touch-control display screen use the touch function, and sound, light and vibration are added to improve the perception for the keys of the customer. However, this way cannot achieve the effect of the physical key 120. At the same time, the reliability is not as good as the physical key 120, and the recognizability is not as strong as the physical key 120. However, the physical keys 120 of some non-touch-control display screen are difficult to prevent the liquid or stain residues on the keys. Although the problem of liquid residue can be solved by paster, it is still difficult to achieve the transparent effect of glass in terms of appearance and meanwhile achieve the effect of touch-control display screen.
Further, referring to
In one embodiment, referring to
Of course, in some embodiments, the support frame 125 can also be omitted, and the key cap 124 can be directly fixed on and connected with the outer panel 1322 or the door body 131 (such as the frame 1311 or the support beam 1312) by other means, such as welding, clamping or other fixing methods, so that it is fixed inside the opening wall of the keyhole 1322b-5.
Further, please refer to
The key cap 124 can be made of elastic material, preferably flexible material with elasticity, so as to improve the pressing feel. In one embodiment, the support frame 125 supports the inner wall of the key cap 124 tightly so that the key cap 124 is tightly matched with the opening wall of the keyhole 1322b-5 to realize the sealing connection. Of course, in some embodiments, the sealing connection between the key cap 124 and the outer panel 1322 can also be realized by arranging a seal and/or filling glue.
This design can integrate the physical key 120 with the screen assembly 132 or an outer cover. In particular, the physical key 120 can be integrated on the screen assembly 132 without damaging the screen. On the basis of ensuring that the screen effect is not affected, the hand feel of the physical key 120 can be satisfied while preventing the liquid inflow and facilitating cleaning Meanwhile, the requirements of frequent disinfection and cleaning of medical devices can be satisfied. In addition, since multiple infusion pumps and/or injection pumps are often used in combination with each other in the prior art, multiple infusion pumps and/or injection pumps are often stacked one above another or even stacked one above another in an installation frame, due to space constraints. In this case, the infusion pump and/or injection pump will usually only expose their front surfaces. In this scheme, the physical key 120 is integrated with the screen assembly 132 and arranged on the front surface of the infusion pump or injection pump, which can facilitate the pressing operation of the user. Especially in case of medical emergency, the medical staff can easily operate the keys on the front surface of the infusion pump or injection pump.
In one embodiment, the shortest distance from the transparent area 1322a of the outer panel 1322 to the hole wall of the keyhole 1322b-5 is 2-4 mm. The surface area of the transparent area 1322a can be enlarged as much as possible without changing the size of the outer panel 1322, so as to expose more display areas of the display screen 1324.
In one embodiment, an outer surface of the pressing portion 1241 of the key cap 124 is level with an outer surface of the outer panel 1322, so that the outer surface of the screen assembly 132 maintains a good flatness. In such a way, the screen assembly 132 and the physical key 120 form an integral plane, which is simple and natural, and easy to clean.

The processor can be operable to send an instruction to the drive device. The peripheral device interface can be connected with a peripheral device such as physical key 220 for signal transmission, so that the processor can control the drive device according to the wish of the user.
The control unit is electrically connected with the physical key 220 for the user to input an instruction. Wherein the physical key 220 includes at least one of a power key, an emergency stop key, a main menu key, a screen unlocking key and a pump door unlocking key. The physical key 220 can control the processor through the bus and peripheral device interface. Specifically, the power key is connected with the control unit. By pressing the power key, the control unit is driven to send a control signal to a power system to power on or off the infusion pump. Specifically, the emergency stop key is connected with the control unit. By pressing the emergency stop key, the control unit is driven to send a control signal to the drive device to move or stop the drive device of the infusion pump. Specifically, the main menu key is connected with the control unit. By pressing the main menu key, the control unit is driven to send a control signal to a display screen control chip for displaying a main injection and infusion interface on a display screen. Specifically, the screen unlocking key is connected with the control unit. By pressing the screen unlocking key, the control unit is driven to send a control signal to a touch-control screen control chip, for activating or deactivating a preset touch-control function or a touch area on a touch-control screen. Specifically, the pump door unlocking key is connected with the control unit. By pressing the pump door unlocking key, the control unit is driven to send a control signal to a pump door switch mechanism for opening or closing the pump door. Generally, the user configure the drugs, the flow speed and capacity of the liquid required by the patient according to the advice of the doctor through the human-machine interface of the infusion pump and selects the infusion apparatus, that can be used together, according to the brand and specification of the infusion apparatus, which is indicated by the infusion pump. The control system of the infusion pump automatically converts the preset characteristic parameters and flow data of the infusion apparatus into the operation parameters of the drive motor. The drive motor drives a camshaft of the peristaltic mechanism to rotate through a deceleration mechanism. The rotation of the camshaft drives a group of pump vanes to implement a linear reciprocation motion. The group of pump vanes cooperate with an extrusion plate to squeeze and release the outer wall of the infusion apparatus in sequence for driving the liquid in the infusion pipe to flow directionally and continuously. In such a way, the quantitative liquid infusion with a constant speed can be obtained.
The pump door 230 is movably installed on the pump body 210 to shield and un-shield the infusion pipe which is installed on the pump body 210, so as to prevent the infusion pipe from being touched by foreign objects during the operation of the infusion pump, thus preventing the infusion operation from being affected. Referring to
Wherein the pump door 230 includes a door body 231 and a screen assembly 232, wherein the screen assembly 232 is connected with the control unit (such as the processor), so that it can display specified information under the control of the control unit. At the same time, the screen assembly 232 can also input instructions and information to the control unit through a touch-control manner. The screen assembly 232 has a display area 2321 which is capable of displaying information. Wherein at least a part of the display area 2321 has a touch-control function, that is, at least part area of the screen assembly 232 is a touch-control display screen which can be connected with the control unit to display information and receive a touch-control instruction of the user. The non-touch-control area of the display area 2321 may only be used for displaying, so it can use an ordinary display screen.
At least a part of the display area 2321 of the screen assembly 232 has a touch-control function. In this way, some physical keys 220 used for inputting instructions can be omitted. For example, only important keys, such as the power key 221, emergency stop key 222, etc., can be remained. In this way, the display area 2321 can be larger, so more information can be displayed, so it is more convenient for the user to view.
Referring to
In this embodiment, the display area 2321 has a roughly elongated shape. Due to the reduction of the original physical key 220 and the full use of the flat shape of the infusion pump, the surface area of the display area 2321 is greatly enlarged, so that more information can be displayed for the user to view.
In the infusion pump according to some of the above embodiments, the display area 2321 of the screen assembly 232 has a width which is greater than or equal to 70% of a width of the front surface of the pump door 230. Since the width of the infusion pump is usually greater than its height, the space in the width direction of the infusion pump can be sufficiently used to form a display area 2321 which has a roughly elongated shape and such display area 2321 is larger than the display area of the existing product. Thus, the display area 2321 is larger and more information can be displayed, so it is more convenient for the user to view. Herein, the “width” refers to a distance between the left side and right side of the infusion pump, in a normal use state. The “height” refers to a distance between the top side and bottom side in the vertical direction of the infusion pump, in a normal use state.
Of course, in a certain embodiment, the display area 2321 of the screen assembly 232 has a width which is greater than or equal to 70% of a width of the front surface of the pump door 230, and meanwhile the display area 2321 of the screen assembly 232 extends from a left side of a center line of the front surface of the pump door 230 to a right side of the center line of the front surface of the pump door 230. In such a way, the surface area of the display area 2321 of the screen assembly 232 is further enlarged.
Of course, the infusion pump can also include other components, such as a plunger pump drive system, storage system, sensing and monitoring system and alarm system, which will not be repeated herein.
Furthermore, referring to
In one embodiment, at least a part of the display area 2321 of the screen assembly has a touch-control function, and information or instructions inputted by the user through the touch-control mode are displayed on the display area 2321 in real time. Referring to
Preferably, in one embodiment, the surface area of the display area 2321 of the screen assembly 232 is greater than or equal to ⅔ of the surface area of the front surface of the pump door 130. In this way, there can be a larger display area 2321 and touch-control area 1321a (that is, the part of the display area 2321 with a touch-control function).
In another embodiment, the entire display area 2321 of the screen assembly 232 is a touch-control display screen with both information display function and touch-control function. The touch-control display screen can be realized by various screen assemblies that can not only realize the information display function, but also realize the touch-control function. The entire touch-control screen can be used as the touch-control area 1321a, which can not only display more information, but also enlarge the operation space of the user and greatly improve the convenience of use.
As shown in
Of course, in other embodiments, the screen assembly 232 is arranged at an upper portion of the front surface of the pump door 230. The left or right portion of the screen assembly 232 extends downward to enlarge the surface area of the screen assembly 232.
Further, as shown in
The screen assembly 232 may have a large screen (for example, an integral touch-control display). In addition, please refer to
In some embodiments, at least one of these small screens can be selected as an ordinary display screen for displaying information only, and at least one of these small screens can be selected as a touch-control display screen that can display information and realize a touch-control function. Under the combination of these small screens, both display and touch-control functions can be completed. For example, some small screens can be used as the aforementioned real-time display area 1321b, and some small screens can be used as the aforementioned touch-control area 1321a.
In order to further enlarge the surface area of the display area 2321 in the screen assembly 232, in one embodiment, the screen assembly 232 adopts the same structure as the above screen assembly 132. For details, please refer to the structure shown in
In other embodiments, the infusion pump can further be provided with some physical keys 220, which can be an emergency stop key 222, a main menu key 224, and a pump door unlocking key 223, in additional to a power supply key 221. These physical keys 220 may be arranged on the pump door 230 or on the pump body 210.
Referring to
In one embodiment, some or all of the physical keys 220 are provided on the screen assembly 232. Specifically, the physical key 220 is installed on an outer panel (as shown above) of the screen assembly 232.
As the touch control screen itself is made of glass, it is complicated to add physical keys 220 to the screen. Therefore, generally, the keys of the touch-control display screen use the touch function, and sound, light and vibration are added to improve the perception of the keys for the customer. However, this way cannot achieve the effect of the physical key 220. At the same time, the reliability is not as good as the physical key 220, and the recognizability is not as strong as the physical key 220. However, the physical keys 220 of some non-touch-control display screen are difficult to prevent the liquid or stain residues on the keys. Although the problem of liquid residue can be solved by paster, it is still difficult to achieve the transparent effect of glass in terms of appearance and meanwhile achieve the effect of touch-control display screen.
In this regard, the structure of the physical key 220 shown in an embodiment of the infusion pump adopts the structure of the physical key 120 shown in
