The present disclosure relates to the technical field of pulse irrigating devices, and more particularly relates to a stepless speed regulation medical pulse irrigator with an LED lamp.
A medical pulse irrigator is a debriding device that provides pulse flushing. When foreign bodies, tissue debris, congestion, etc. in a wound are thoroughly eliminated, a secondary injury to surrounding normal tissues is avoided, and the risk of occurrence of cross infection is lowered. A medical pulse debridement irrigator is generally composed of a handle, a spray nozzle and a battery pack. During use, the handle is held and aligned with a wound surface for flushing. The medical pulse irrigator is one of commonly used instruments for acute and chronic wound debriding.
At present, there have been similar irrigators on the market, but they have a monotonous irrigating speed and extremely high pressure, so that some patients sensitive to pain of wounds are reluctant to use such an instrument, and traditional low-efficiency and high-working-intensity methods such as a manual injector are still used for debriding. Moreover, when an irrigator is used for irrigating, flushing fluid is likely to splash onto a contaminated fluid collection bag, resulting in obstruction to a field of view and inconvenience in debriding.
It is under this background that the present disclosure is proposed. In a wound debriding process, this disposable stepless speed regulation medical pulse irrigator with an LED lamp can use a steplessly regulatable irrigating speed and pressure to reduce the discomfort of a patient with this instrument according to the wound pain sensitivity of the patient, and can improve the wound debriding efficiency and relieve the workload of medical staffs at the same time. When the irrigating fluid splashes onto the contaminated fluid collection bag to obstruct the field of view, the LED lamp can be turned on through an LED lamp control switch to assist in the observation for the wound, which facilitates debridement personnel to determine whether debridement is thoroughly completed, so that the debridement time and cost are greatly saved.
The present disclosure has been developed to provide a stepless speed regulation medical pulse irrigator with an LED lamp to improve on some shortcomings of existing pulse devices of this general kind on the present market: Due to a monotonous irrigating speed and a relatively high pressure, some patients with pain sensitivity to wounds are reluctant to choose such an instrument, and instead choose traditional low-efficiency and high-working-intensity methods such as syrings for cleansing. Moreover, when an irrigator is used for debriding, irrigating fluid is likely to splash onto a contaminated fluid collection bag, resulting in obstruction to observation of debridement.
In order to continuing improve on the shortcomings mentioned above, the present disclosure provides the following technical solution: A stepless speed regulation medical pulse irrigator with an LED lamp includes an upper handle, a lower handle, a pump body, a fluid tube, stepless speed regulation control parts, a spray nozzle part, a power supply part and an LED lamp. The pump body is arranged inside the upper handle; the left side of the pump body is connected with a piston, and the bottom end of the piston is provided with a big gear; a locating pin is arranged in the middle of the bottom end of the big gear, and a motor-gear assembly is arranged below the big gear; the stepless speed regulation control parts are mounted on a side edge and the rear side of the motor-gear assembly; and the stepless speed regulation control part on the rear side of the motor-gear assembly is connected with an LED lamp control switch.
Typically, the stepless speed regulation feature is composed of a stepless speed regulation control panel (6), a tact switch (4), a linear speed regulation switch (5) and the motor-gear assembly (7). The rotation speed of the motor-gear assembly (7) may be steplessly controlled by operating the tact switch (4) and the linear speed regulation switch (5).
Typically, a self-locking structure between the tact switch (4) and the linear speed regulation switch (5): the left view of
Typically, the stepless speed regulation may be carried out throughout 0-6 V-12 V, in which steady continuous operation can be realized at any speed. Two reference speeds are preset: a low speed (6 V) and a high speed (12 V). The speeds are shown in
Typically, the tact switch in the stepless speed regulation system is provided with an LED state indication lamp, which is user-friendly and improves the availability.
Typically, the LED lamp is a high-brightness white light or high-brightness warm light, and a pump housing assembly is in tight fit with the left side of the outer wall of the upper handle; and the LED lamp, the upper handle and the lower handle are fixedly connected.
Typically, a battery case (28) in a battery pack (16) is provided with a fuse, so that a danger caused by short circuiting of the product can be avoided, and the safety of the product is effectively improved.
Typically, the product is sterilized by an environmentally-friendly efficient sterilization method: plasma sterilization that is short in sterilization time and can effectively improve the production efficiency and reduce the cost; after the sterilization is completed, there is no residue, and the product can be used immediately, which is extremely safe to human and the environment.
Typically, a tube with wire (13) is connected with a handpiece through tube connecting bodies (26, 27) and wire connecting bodies (24, 25). The handpiece and the tube with wire are packaged separately. During use, they are connected together to facilitate sterilization for the product; moreover, mis-initiation of the product during transportation can also be avoided; in this way the safety of the product is improved.
Compared with the related art, the present disclosure has the beneficial effects:
1. In a process of pulse debriding of a wound with the stepless speed regulation medical pulse irrigator with the LED lamp, for some patients sensitive to pain of the wound or having more fragile wound tissues, the rotation speed of a motor can be controlled through the linear stepless switch to adjust the speed and pressure of the flushing fluid to achieve the best irrigating effect.
2. A combined switch structure of the stepless speed regulation medical pulse irrigator with the LED lamp can realize self-locking in the use process to ensure that the irrigating speed is gradually increased from low to high, instead of a sudden increase causing the patient to feel uncomfortable.
3. In the process of pulse debridement with the disposable medical pulse irrigator with the LED lamp, when the irrigating fluid splashes onto the contaminated fluid collection bag to obstruct the observation, the LED lamp can be turned on through an LED lamp control switch to assist in the observation for the wound, which facilitates debridement personnel to determine whether debridement is thoroughly completed, so that the debridement time and cost are greatly saved.
4. The LED lamp is fixed below the handle, connected to the pump housing assembly, and fixed in the lower handle to make the structure stabler, so that the LED lamp cannot completely pass through a through hole of the pump housing assembly and is prevented from falling off, and the firmness of the structure of the device is improved.
5. The battery pack of the product is provided with a fuse, so that a danger caused by short circuiting of the product can be avoided, and the safety of the product is effectively improved.
6. The product is sterilized by plasma sterilization method. Compared with Gamma irradiation sterilization commonly used for existing products of this general kind, the plasma sterilization is short in time, and can effectively improve the production efficiency and reduce the cost; after the sterilization is completed, there is no residue, and the product can be used immediately, which is extremely safe to human and the environment.
7. The tube with wire of the product and the handpiece are of a split type structural design. During packaging, the handpiece and the tube with wire are packaged separately. During use, they are connected together to facilitate sterilization for the product; and moreover, mis-initiation of the product during transportation may also be avoided, which improves the safety of the product.
