The invention relates to elastic glove donning equipment, in particular to equipment for airtightness-detecting, sterilizing and donning of elastic gloves, and belongs to the technical field of medical sterilizing equipment.
Elastic gloves are indispensable articles for medical operation. Generally, coordination of nurses or other personnel is needed when the elastic gloves are donned at present, the gloves are difficult to don, the exterior surfaces of the gloves can be contaminated and damaged easily, and consequentially medical negligence such as cross infection can be caused. Meanwhile, since non-plastic elastic gloves generally have good elasticity, the non-plastic elastic gloves are more difficult to don and cannot be donned and used in emergencies such as nursing during a physical examination or a surgical operation. Part of the existing auxiliary equipment technically provides a certain convenience for donning the elastic gloves, however, the existing auxiliary equipment needs to be controlled manually and does not have the glove airtightness automatic-detecting function, the sterilization function and the like, and consequentially medical negligence can be caused easily.
The invention aims to overcome the defects in the prior art and provides equipment for elastic glove airtightness-detecting and donning with a sterilization function, which is reasonable in structural design, fast and convenient to use, and capable of effectively reducing cross infection.
The technical scheme of the invention is realized by the following solution.
The equipment for elastic glove detecting and donning with the sterilization function comprises sterilization cavities, wherein elastic gloves are fixedly mounted in the sterilization cavities, fingerstall sections of the elastic gloves are located inside the sterilization cavities, cavity through holes used for mounting sleeve fixing rings are formed in one side of the sterilization cavities, and the sleeve ends are fixed to the sterilization cavities through the sleeve fixing rings; the sterilization cavities are further provided with pressure detection switches which are used for detecting the internal pressure of the sterilization cavities and also used for closed-loop control; the sterilization cavities are further provided with air pipeline ports used for being connected with an air pump, the air pump is connected with the sterilization cavities through electromagnetic valves, the sterilization cavities and the electromagnetic valves are further connected with a control cabinet, and the electromagnetic valves are controlled through the control cabinet, so that the elastic gloves are stretched to be donned under negative pressure and contracted to be released under positive pressure.
Sterilization devices are arranged in each sterilization cavity and include an ozone generation device, a pasteurization device, an ultraviolet sterilization device and a negative ion sterilization device.
The equipment for elastic glove airtightness-detecting and rapid-donning with the sterilization function further comprises air suction cycles used for forming negative-pressure areas in the airtight areas between the interiors of the sterilization cavities and the exteriors of the gloves to make the gloves expand to become larger, and air inflation cycles used for forming positive-pressure areas in the airtight areas between the interiors of the sterilization cavities and the exteriors of the gloves to attach the gloves completely to human hands; an air inlet of the air pump is connected with ports A of the electromagnetic valves and communicates with air outlets of the sterilization cavities through an air suction pipeline, and an air outlet of the air pump is connected with ports B of the electromagnetic valves and communicates with the outside atmosphere, so that the air suction cycles are formed; the air outlet of the air pump is connected with the ports B of the electromagnetic valves and communicates with air inlets of the sterilization cavities through an air inflation pipeline, and the air inlet of the air pump is connected with the ports A of the electromagnetic valves and communicates with the outside atmosphere, so that the air inflation cycles are formed.
The air suction pipeline and the air inflation pipeline are each provided with a flow regulating valve, a one-way valve and a sterilizing filter, so that the air cleanliness of the whole pipelines is guaranteed, and secondary pollution of the gloves is prevented.
When the elastic gloves to be donned are fixed to the sleeve fixing rings of the sterilization cavities, the cavity through holes of the sterilization cavities are airtight relative to the outside, and thus a pressure maintaining state is achieved.
The cavity through holes are round or quasi-round or oval or quasi-oval or are of an egg-shaped or quasi-egg-shaped structure with the upper section being sharp and the lower section being obtuse.
The opening edge of each cavity through hole extends towards the two ends in the radial direction from one end of the cavity through hole, and the outer edges of each cavity through hole are in a horn shape or a step shape or a bevel shape; the horn shape refers to that the radius of the opening edge of each cavity through hole becomes large gradually, and the opening edge of each cavity through hole is in smooth arc transition; the step shape refers to that the radius of the opening edge of each cavity through hole becomes larger gradually, and the opening edge of each cavity through hole is in a right-angled step shape; the bevel shape refers to that the radius of the opening edge of the cavity through hole becomes larger gradually, and the opening edge of each cavity through hole is in smooth bevel transition.
The opening edge of each cavity through hole extends towards the two ends in the radial direction from one end of the cavity through hole, and is of an asymmetrical structure with the axis of the cavity through hole as the center.
When the opening edges are of an asymmetrical structure, the opening edges are of the specific structure where the opening edges extend towards the two ends in the radial direction by different dimensions, or the opening edges extend towards the two ends in the radial direction in different shapes, namely one end of the opening edges is of a right-angled step structure, and the other end of the opening edges is of a bevel structure.
The outer edges of the cavity through holes are of a stretchable structure; when the gloves are about to be mounted in the cavity through holes, the cavity through holes contract, and the calibers are decreased; after the gloves are mounted, the cavity through holes expand, the calibers are restored, and the gloves are well fixed. When the gloves are donned on the hands, the calibers of the cavity through holes are decreased again while inflation is conducted for positive pressure, and thus the gloves are released easily.
According to the stretchable structure, the opening edges are made of elastic materials, and elastic pieces are arranged between the opening edges and the cavity through holes; when the gloves are about to be mounted in the cavity through holes, the opening edges move towards the interiors of the cavity through holes under the effect of external force, the elastic pieces are stretched to make the cavity through holes contract, and the calibers are decreased; after the gloves are mounted, the external force disappears, the opening edges restore to the original state under the effect of the elastic pieces, the calibers are restored at the same time, and the gloves are well fixed. When the gloves are donned on the hands, the calibers of the cavity through holes are decreased again while inflation is conducted for positive pressure, and thus the gloves are released easily.
According to the stretchable structure, movable buckle devices are arranged in the positions, close to the opening edges of the outer walls of the cavity through holes, the buckles contract when the gloves are mounted, and oversleeves are fixed through the buckles; before vacuumizing is conducted for negative pressure, the buckles bounce to well fix the gloves; after the gloves are donned, inflation is conducted for positive pressure, the buckles contract again, and the gloves are released easily.
The airtightness of the gloves is detected through positive pressure and negative pressure, namely, vacuumizing is conducted for negative pressure after the gloves are mounted, the gloves are made to expand, the negative pressure of the cavities is detected continuously through pressure sensors in the process, and it indicates that the gloves have holes and cannot be used if the negative pressure of the cavities cannot be achieved or the negative pressure is decreased after the air pump stops. If air leakage is slow and cannot be confirmed, inflation can be conducted for positive pressure, the gloves are made to protrude and expand, the positive pressure is detected through the pressure sensors, and whether the gloves have holes or not can be confirmed through manual observation.
The cavity through holes can be made of different materials and have different dimensions, so that the sleeve fixing rings for the gloves under different stress conditions can be mounted on the cavity through holes in a sleeved mode conveniently and can be dismounted easily under positive pressure after the gloves are donned.
Compared with the prior art, the invention has the following beneficial effects.
The equipment for elastic glove detecting and donning with the sterilization function of the invention is simple and reasonable in structural design, and the elastic gloves can be stretched to be donned under negative pressure and contracted to be released under positive pressure by controlling the electromagnetic valves through the control cabinet.
The equipment can be used for sterilization of elastic gloves made of various elastic materials, and the elastic gloves can be donned rapidly in an extremely short time; the pressure detection switches are used for detecting the internal pressure of the sterilization cavities, and the air pipelines are used for inflation and deflation so that it can be guaranteed that the gloves are airtight and in the proper state when donned; the wearer controls the switches to generate negative pressure, balanced pressure and positive pressure in the sterilization cavities, so that the elastic gloves are made to contract and automatically fall onto the hands of the wearer from the sleeve fixing rings after being donned; the cleanliness and safety of the equipment and the elastic gloves are guaranteed through physical and chemical sterilization methods including filter sterilization, ozone sterilization and the like, and the sterilization methods are harmless to human bodies. Since the physical and chemical sterilization methods including filter sterilization, ozone sterilization and the like are adopted for the equipment and the air pipelines relevant to glove donning, the sanitation requirement for medical operation can be met.
Furthermore, a pedal switch is used for motion control, so that the wearer is prevented from touching other objects besides the gloves with hands; manual touch control and manual monitoring are not needed during the whole donning process, cross infection can be effectively avoided, and a system is stable and reliable.
Furthermore, the positive pressure threshold value and the negative pressure threshold value of the pressure detection switches can be adjusted to adapt to elastic gloves made of different elastic materials.
Furthermore, in a system control scheme, a two-position switch of the pedal switch and a relay are matched and designed to be of an interlocking form, so that false operation of the system is avoided, and using safety is guaranteed.

The elastic gloves 2 are made to stretch by means of negative pressure (lower than the standard atmospheric pressure) in the sterilization cavities 1 and thus can be donned easily; when the completeness of the gloves is broken, automatic checking can be conducted through the internal pressure states of the sterilization cavities 1 and the stretching states of the gloves. The elastic gloves 2 are made to contract by means of positive pressure (higher than the standard atmospheric pressure) in the sterilization cavities 1 and thus can be donned rapidly.
