Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, specifically to an automatic medical glove wearing machine. Background Technology

[0002] Medical gloves, as critical medical protective equipment, require proper and aseptic wearing as a crucial step in preventing cross-infection. Traditional methods of donning gloves rely primarily on manual operation by medical personnel, demanding skill from the operator to ensure the gloves do not become contaminated, curl, or tear during the unfolding and insertion process. To improve ease of use and standardization, several auxiliary donning devices and methods have emerged, such as using fixed glove supports to assist unfolding or employing simple mechanical mechanisms to open the glove opening for hand insertion. These existing technological solutions simplify the process to some extent, reduce the risk of direct contact with contaminants, and affirm their positive significance in promoting standardized procedures.

[0003] However, existing technical solutions still have certain limitations. Manual donning or simple auxiliary devices still require a high level of hand posture and operational proficiency from the user, making it difficult to ensure quick and accurate alignment between the glove and the palm each time the glove is donned. This can easily lead to problems such as difficulty in putting on the glove, wrist folding, or fingertip adhesion due to alignment deviations, affecting donning efficiency and success rate, and may even cause accidental damage to the glove. In addition, some relatively complex automated solutions may have problems such as poor mechanism linkage, asynchronous movements, high energy consumption, or inconvenient reset, affecting the reliability of the equipment and its continuous operation capability.

[0004] Therefore, since the existing needs are not met, we have proposed an automatic medical glove wearing machine. Summary of the Invention

[0005] This invention provides an automatic medical glove wearing machine. The solution utilizes an ergonomically designed palm-shaped groove, allowing users to naturally place their hands without deliberate adjustment, effectively lowering the barrier to entry. The hand then moves steadily and vertically downwards under the precise guidance of the lead screw and limiting slide, laying a precise alignment foundation for subsequent steps. A unique corrugated airbag system converts and stores the downward kinetic energy into pneumatic potential energy, providing a unified and energy-efficient power source for multiple subsequent coordinated actions. Its synchronous isobaric air supply design ensures the initial consistency and balance of all actuator movements. Finally, the storage rack, through a two-stage movement of overall circumferential positioning followed by forward pushing, simulates the ideal glove wearing trajectory. This not only greatly improves the success rate of first-time wearing and wrist fit but also effectively avoids problems such as jamming, curling, and glove damage that easily occur in traditional wearing methods, solving the problems mentioned in the background art.

[0009] As an optional embodiment of the automatic medical glove wearing machine of the present invention, a control valve is provided in the pipeline between the air jet and the energy storage chamber, and a pressure relief valve is provided on the energy storage chamber.

[0010] As an optional solution for the automatic medical glove wearing machine described in this invention, the corrugated airbag is provided with an air inlet one-way valve, and the elastic coefficient of the second spring is greater than that of the first spring.

[0011] As an optional solution for the automatic medical glove wearing machine described in this invention, the movable slide plate has a third cavity inside, a contact sensor is provided at the bottom of the third cavity, and the transmission screw is driven and connected to an embedded motor located inside the wearer body.

[0013] As an optional solution for the automatic medical glove wearing machine described in this invention, the shelf is used to support medical gloves with the wrist turned outward.

[0014] The present invention has the following beneficial effects: 1. This automatic medical glove donning machine features an ergonomically designed palm-shaped groove, allowing users to naturally place their hands without needing to adjust them, effectively lowering the barrier to entry. The hand then moves steadily and vertically downwards under the precise guidance of the lead screw and limit slide, laying a precise alignment foundation for subsequent steps. The unique corrugated airbag system converts and stores the downward kinetic energy into air pressure potential energy, providing a unified and energy-saving power source for multiple subsequent coordinated actions. Its synchronous isobaric air supply design ensures the consistency and balance of the initial movements of all actuators. Finally, the shelf simulates the ideal glove wearing trajectory through a two-stage movement of first overall circling positioning and then pushing forward. This not only greatly improves the success rate of donning on the first try and the fit of the wrist, but also effectively avoids the problems of jamming, curling, and glove damage that are common in traditional donning methods.

[0015] 2. This automatic medical glove donning machine, through the setting of the air jet nozzle, allows the "micro-inflation" design to inject a gentle airflow into the glove, significantly improving the wearing experience and efficiency. It forms an air film between the inner wall of the glove and the skin, greatly reducing friction and making the wearing process smooth and effortless. Moreover, the airflow can simultaneously clean the internal powder, improving hygiene and ensuring that the glove is fully unfolded, avoiding adhesion and damage, and reducing the need for adjustment. At the same time, the overall reset process is highly automated and energy-saving, mainly relying on the elastic potential energy and air pressure difference stored in the system to achieve rapid and quiet cyclic preparation. This not only ensures efficient and smooth continuous operation, but also reduces the load on core components and effectively extends the overall service life of the equipment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, please refer to Figures 1-6 When a user needs to put on medical gloves, they simply place their palm naturally into the palm-shaped groove 106 at the top of the movable slide plate 101. The shape of the palm-shaped groove 106 provides a natural initial positioning, ensuring the correct hand posture. This ergonomic design effectively reduces the user's learning cost. At this time, the contact sensor integrated at the bottom of the third cavity 108 senses the pressure signal and immediately transmits the start command to the embedded motor. The motor then begins to rotate forward, driving the transmission screw 112 to rotate. Since the rear end of the movable slide plate 101 is engaged with the transmission screw 112 through a threaded pair, and its movement is strictly constrained by the limiting slide rod 102, the rotation of the transmission screw 112 is converted into the smooth and vertical downward movement of the movable slide plate 101 along the first cavity 104. This screw mechanism, which converts rotational motion into linear motion, is not only compact and precisely controlled, but the limiting slide rod 102 also effectively solves the problem of radial sway, ensuring the stability of the palm's trajectory during the downward movement and laying the foundation for subsequent precise alignment.

[0020] As the movable slide plate 101 moves downward, the limiting slide bar 102 fixed to its bottom moves downward in sync, pushing the squeezing slide plate 111 to move downward in the second cavity 105, compressing the corrugated airbag 107. The corrugated airbag 107, as a flexible air pump element, has its internal air discharged into the energy storage cavity 109 for temporary storage. This process is a key energy conversion and storage step, which converts the mechanical energy driven by the motor into air pressure potential energy and stores it. It cleverly provides a unified drive for multiple subsequent coordinated actions without the need for an additional power source, demonstrating the advantages of integrated energy-saving design. The energy storage cavity 109 is connected to the air storage cavity 113 through multiple air delivery channels 110. A pressure check valve is provided at the connection point, and its preset opening pressure is higher than the maximum dynamic pressure generated by the movable slide plate 101 on the corrugated airbag 107 when it moves downward. This design ensures that the air pressure energy can be fully accumulated until the moving skateboard 101 drives the palm down to the lowest preset position. At this point, the pressure in the energy storage chamber 109 reaches its peak value and exceeds the preset value of the valve. The pressure check valve opens instantly, and the accumulated gas flows into all the air storage chambers 113 at the same pressure. This synchronous and equal pressure air supply design fundamentally ensures the consistency of the initial movement and pressure balance of all the actuators, which is the core of maintaining symmetry and stability in subsequent movements.

[0021] It should be noted that pressure check valves are a commonly used and existing technology in this field. Users can adjust them according to actual conditions and their own needs, which will not be elaborated here.

[0022] When the air pressure in the air storage chamber 113 pushes the bottom end face of the first connecting rod 202, its top is connected to the moving frame 201 through the shelf 204 and the second connecting rod 206. Since the elastic coefficient of the second spring 207 is significantly greater than that of the first spring 203, in the initial stage, the entire moving assembly 2 is pushed by the first connecting rod 202 as a rigid whole, smoothly sliding out from the side storage position of the wearable device body 1 and inserting into the open end of the third cavity 108, which is now aligned. This "whole movement" stage allows the shelf 204, which carries the pre-fitted and wrist-out medical glove, to accurately surround the stationary palm, completing the crucial spatial positioning.

[0023] When the movable frame 201 slides to the end of its stroke and is stopped by the mechanical limit, the force begins to overcome the stronger second spring 207, forcing the shelf 204 to achieve a "secondary movement" on the track of the movable frame 201, that is, to extend forward relative to the movable frame 201. The core advantage of this two-stage motion design lies in realizing the "coarse positioning first, then precise pushing" fitting logic. It first ensures the macroscopic alignment of the glove opening with the wrist area, and then gently and steadily pushes the glove towards the base of the palm. This physical process simulates the ideal manual wearing trajectory, greatly improving the success rate of fitting on the first try and the fit of the wrist, effectively avoiding jamming, curling, or folding at the base caused by misalignment, and significantly reducing the risk of glove breakage under critical wearing conditions.

[0024] Example 2 aims to further improve the wearing efficiency of medical gloves. This example is an improvement on Example 1. For details, please refer to Example 2. Figures 1-6 As the shelf 204 is pushed into place, another independently controlled air circuit begins to operate. When the pressure in the energy storage chamber 109 reaches a higher preset value (triggered under program control after the shelf 204 is in place), the valve connecting the energy storage chamber 109 and the air outlet 205 opens, and a gentle and continuous airflow is injected into the inside of the glove, causing the fingers and palms of the glove to expand moderately. This "micro-inflated" state creates multiple benefits: it forms an extremely thin air film between the inner wall of the glove and the skin, effectively reducing contact friction and allowing the glove to be slipped on more smoothly; the airflow can blow away any talcum powder or dust that may be present, improving hygiene; at the same time, it ensures that the glove, especially the fingertips, is fully expanded, eliminating internal adhesion and providing users with a more comfortable and reliable wearing experience. This design replaces the finger adjustment movements that may be required in traditional manual dressing, further reducing the risk of contamination.

[0025] After the device is donned, the reset process is fully automatic and requires very little power. The embedded motor receives a signal and rotates in the reverse direction, causing the transmission screw 112 to reverse as well. This causes the moving slide plate 101, along with the user's gloved hand, to rise smoothly back to its initial height. As the slide plate 111 is compressed upwards, the corrugated airbag 107 returns to its original shape due to its elasticity, generating negative pressure. This negative pressure draws in outside air through a pre-set one-way valve, completing the pneumatic system's self-replenishment and preparing for the next compression and energy storage. Simultaneously, the system pressure is rapidly released through the pressure relief valve. Under the restoring force of the first spring 203, the... The first link 202 drives the shelf 204 to retract synchronously into the air storage chamber 113, realizing the precise synchronous reset of multiple actuators. Then, under the restoring force of the second spring 207, the shelf 204 returns to its initial relative position relative to the moving frame 201. Finally, the moving frame 201 slides back into its storage position inside the wearable device body 1. The entire reset process is clear in sequence and logically rigorous. It mainly relies on the stored elastic potential energy for driving, with extremely low energy consumption. This ensures that the device can be ready quickly, quietly, and reliably, realizing continuous and efficient wearable operation cycles and extending the service life of core components such as motors.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
