Description

Technical Field

[0001] The invention relates to a sterile glove auxiliary wearing device, belonging to the technical field of sterile glove wearing devices. Background Art

[0002] Sterile gloves are widely used in medical surgery, wound treatment, laboratory operations, infection control and other scenarios. They are mainly used to prevent cross-infection, ensure the sterility of the operating area and instruments, and protect the safety of patients and operators.

[0003] The steps for putting on sterile gloves include: first, the operator is required to prepare sterile gloves in a sterile environment and clean and disinfect their hands. Next, open the glove package to ensure that the inner and outer surfaces of the gloves are not contaminated. When putting on, use the non-dominant hand to grasp the edge of the cuff of the glove (the inner surface of the glove at the outward fold) and put on the first glove to avoid touching the outside of the glove. Then, use the gloved dominant hand to grasp the edge of the cuff of the second glove and put it on the other hand. After completion, the gloves need to be adjusted to ensure comfort and check sterility to prevent contamination due to damage to the gloves or improper wearing.

[0004] There are some inconveniences when wearing sterile gloves. First, during the wearing process of sterile gloves, the skin of the hands is likely to directly contact the outer surface of the sterile gloves, resulting in the wearing not meeting the requirements. Secondly, during the wearing process, the cuff of the sterile glove can only be put on the cuff of the sterile surgical gown by pulling hard on one side with one hand. The force on one side is uneven, which can easily tear the sterile gloves. There are also some automated glove wearing devices on the market, but they often have complex operating structures and high costs. In addition, during the wearing process, they cannot meet the requirements of sterile wearing. These have limited their popularity and application.

[0005] Therefore, a sterile glove assisting donning device that can be used in a sterile room is designed, which has a simple structure, is easy to operate, and is quick to don. During the donning process, the skin of the medical staff's hands will not contact the outer surface of the sterile gloves, thereby better meeting the requirements of sterile donning.

[0062] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0063] The sterile gloves 3 auxiliary wearing device is mainly used to assist medical staff in semi-automatic sterile wearing of sterile gloves 3, and is mainly suitable for sterile places. According to the wearing specifications of sterile gloves 3, the medical staff's cleaned hands still cannot have any direct contact with the outer surface of the sterile gloves 3, and can only contact the inner surface of the sterile gloves 3, which makes it difficult for medical staff to wear sterile gloves 3.

[0064] At present, for the convenience of wearing, the sterile gloves 3 are provided with a cuff 301 before leaving the factory. The cuff 301 of the sterile gloves 3 refers to a folded section formed by folding the inner surface of the opening 302 of the sterile gloves 3 outward.

[0065] like Figure 1-Figure 3 As shown, in one embodiment, the sterile glove 3 auxiliary wearing device includes:

[0066] The box body 1 has a sealed inner cavity, a wearing hole 101 is provided on one side of the box body 1, and a tray opening 102 is provided on the box body 1 below the wearing hole 101 to allow a sterile tray 103 to enter. The box body 1 is made of medical stainless steel or plastic. Generally, 1-2 wearing holes 101 are provided on the box body 1, and each wearing hole 101 has the same auxiliary wearing structure.

[0067] The sterile tray 103 is a medical stainless steel sterile tray 103. A mark 104 is provided on the sterile tray 103 to remind the sterile gloves 3 to be placed. The sterile tray 103 is pushed out or retracted from the tray opening 102 into the box 1 manually or by an electric push rod (not shown). If an electric method is adopted, the electric push rod is fixed to the bottom of the box 1, and the telescopic end of the electric push rod is connected to the sterile tray 103. Preferably, the sterile tray 103 can be placed on a track at the bottom of the box 1. The sterile tray 103 is limited to the position to be worn by the limit block 107 inside the box 1. At this time, the cuff 301 of the sterile glove 3 placed in the mark 104 of the sterile tray 103 is just below the suction cup 403.

[0068] like Figure 6 As shown, the suction cup mechanism 4 includes a suction cup 403 installed in the box body 1, a mounting seat 402 and a first telescopic rod 401. The suction cup 403 adopts a medical rubber suction cup 403, and the suction cup 403 is connected to a negative pressure system (not shown in the figure), and the negative pressure system provides adsorption force. When the sterile tray 103 is placed in a preset position in the box body 1, the suction cup 403 is located directly above the cuff 301 of the sterile glove 3, and the suction cup 403 is fixed on the mounting seat 402, and the mounting seat 402 is driven up and down by the first telescopic rod 401 fixed inside the box body 1.

[0069] Even if the sterile glove 3 is sucked up by the suction cup 403, the cuff 301 of the sterile glove 3 is still loose, and it is difficult for medical staff to directly put their hands into the sterile glove 3, and it is difficult to complete the wearing. Therefore, the following structure needs to be designed.

[0070] In order to initially unfold and tighten the cuff 301 of the sterile glove 3, a vertical expansion assembly is designed, including a flipping drive mechanism 6 and a vertical expansion mechanism 5 installed on the mounting seat 402. The flipping drive mechanism 6 drives the vertical expansion mechanism 5 to flip up and down. After flipping downward, the vertical expansion mechanism 5 enters the interior from the opening 302 of the cuff 301 of the sterile glove 3 and vertically expands the opening 302 of the cuff 301.

[0071] like Figure 3-Figure 6 , Fig.10 As shown, in some embodiments, the vertical expansion mechanism 5 includes a first plug plate 501, a second plug plate 502, and a second telescopic rod 503, wherein the first plug plate 501 is fixed to the shell of the second telescopic rod 503, and the second plug plate 502 is fixed to the telescopic end of the second telescopic rod 503.

[0072] like Fig.10As shown, in some embodiments, the flipping drive mechanism 6 includes a flipping motor 601, a worm 602, a turbine 603, a swing arm 604, and an articulated seat 605. One end of the swing arm 604 is fixed to the housing of the second telescopic rod 503, and the other end of the swing arm 604 is fixed with a turbine 603. The turbine 603 is hinged on the articulated seat 605. The articulated seat 605 and the flipping motor 601 are fixed on the mounting seat 402. The worm 602 is fixed on the rotating shaft of the flipping motor 601, and the worm 602 is meshed with the turbine 603.

[0073] The flip driving mechanism 6 drives the vertical expansion mechanism 5 to flip from above the initial mounting seat 402 to below the mounting seat 402 , so that the first plug plate 501 and the second plug plate 502 are inserted into the opening 302 of the cuff 301 of the sterile glove 3 .

[0074] By adopting the flip driving mechanism 6, the wearer can suspend when there is no power, and will not fall. After flipping, the vertical expansion mechanism 5 can be kept away from the wearing part, and will not be easily touched by mistake.

[0075] like Figure 6 As shown, in order to make the first plug plate 501 and the second plug plate 502 more conveniently and accurately inserted into the opening 302 of the cuff 301 of the sterile glove 3, a double suction cup 403 structure is designed, the distance between the two suction cups 403 is greater than the width of the first plug plate 501 and the second plug plate 502, and the first plug plate 501 and the second plug plate 502 are located in the middle of the two suction cups 403, so that when the double suction cup 403 sucks up the sterile glove 3, the first plug plate 501 and the second plug plate 502 of the vertical expansion mechanism 5 can be quickly and accurately inserted into the opening 302 of the cuff 301 of the sterile glove 3 through the flip driving mechanism 6. Then, through the extension of the second telescopic rod 503, the first plug plate 501 and the second plug plate 502 are gradually separated, and the opening 302 of the cuff 301 of the sterile glove 3 is vertically expanded.

[0076] At this time, although the opening 302 of the cuff 301 of the sterile glove 3 is vertically expanded, if the glove is directly put on, the hand 13 of the medical staff will contact the first plug plate 501 and the second plug plate 502, causing contamination to the first plug plate 501 and the second plug plate 502, affecting the next wearer. In addition, at this time, only the finger part of the sterile glove 3 can be put on, and the folded cuff 301 cannot be tied to the cuff 10 of the sterile surgical gown 9.

[0077] like Figure 3-Figure 17 As shown, in order to achieve completely sterile wearing, a lateral expansion component is also designed, including a translation mechanism 7 and a lateral expansion mechanism 8 installed in the box 1. The translation mechanism 7 drives the lateral expansion mechanism 8 to translate back and forth. When the lateral expansion mechanism 8 translates toward the vertical expansion mechanism 5, it enters the folded part of the cuff 301 from the finger end of the sterile glove 3 and expands the folded part of the cuff 301 laterally.

[0078] like Figure 3 , Figure 4 As shown, the translation mechanism 7 includes a third telescopic rod 701, a guide rail 702, a sliding seat 703, and a linear bearing 704. The central axis of the third telescopic rod 701 is parallel to the central axis of the wearing hole 101. The shell of the third telescopic rod 701 is fixed on the inner wall of the box body 1 opposite to the wearing hole 101. Guide rails 702 are arranged in parallel on both sides of the third telescopic rod 701. The bottom of the sliding seat 703 is mounted on the guide rail 702 through a linear bearing 704 and is driven to translate through the third telescopic rod 701.

[0079] like Figure 3-Figure 4 , Fig.10 As shown, the lateral expansion mechanism 8 includes a slide rail 801, a threaded rod 802, a slider 803, a forward and reverse motor 804, a first inner support 805, a second inner support 806, and a roller 807. The slide rail 801 and the threaded rod 802 are parallel to each other and are installed together on the slide seat 703. The slide rail 801 and the threaded rod 802 are both perpendicular to the guide rail 702, wherein the threaded rod 802 is rotatably installed with the slide seat 703 through a bearing, the slider 803 is sleeved on the slide rail 801 and the threaded rod 802, the threaded rod 802 and the slider 803 are matched by threads, the forward and reverse motor 804 drives the threaded rod 802 to rotate, and the threaded rod 802 is provided with a wear hole 10 The forward thread and the reverse thread are symmetrically arranged with the central axis as the symmetry axis, and a slider 803 is installed on the forward thread and the reverse thread respectively. The first inner support 805 and the second inner support 806 are symmetrically fixed on the sliders 803 of the forward thread and the reverse thread. The ends of the first inner support 805 and the second inner support 806 are bent toward one side of the middle part of the sterile glove 3. A vertical roller 807 is arranged at one end of the first inner support 805 and the second inner support 806 that contacts the folded part of the cuff 301 of the sterile glove 3. The upper and lower height difference of the roller 807 ends of the first inner support 805 and the second inner support 806 is less than the expanded distance between the first plug plate 501 and the second plug plate 502.

[0080] like Figure 1-Figure 4 As shown, the auxiliary wearable device in this embodiment adopts a double station: a pair of wearing holes 101 are provided on one side of the box 1, each wearing hole 101 corresponds to a hand of a medical staff, each hand corresponds to a sterile glove 3, and each sterile glove 3 is provided with a set of suction cups 403, vertical expansion mechanism 5, flip drive mechanism 6, lateral expansion mechanism 8, lateral expansion mechanism 8, hand support plate 11, etc. The two station structures are symmetrically arranged.

[0081] The transverse expansion mechanism 8 is used to drive the transverse expansion mechanism 8 to move toward the center and insert into the cuff 301 of the sterile glove 3, and then expand transversely, so as to facilitate the withdrawal of the vertical expansion mechanism 5 to avoid contamination during wearing. The third telescopic rod 701 is used to push the sterile glove 3 toward the human body, slowly unfold the cuff 301 of the sterile glove 3, and put it on the cuff 10 of the sterile surgical gown 9.

[0082] In some embodiments, an ozone generator 2 is disposed in the box 1, a first one-way valve that only allows air to enter and a suction interface for ventilation are disposed on the box 1, and a second one-way valve that only allows air to be discharged is disposed in the suction interface.

[0083] The ozone generator 2 can be used to sterilize the interior of the box 1 to ensure that the interior is operated in a sterile environment. When the ozone disinfection is completed, the internal ozone gas is extracted from the suction interface through the suction device, and the air enters the interior through the first one-way valve.

[0084] In some embodiments, the first plug plate 501 and the second plug plate 502 are plates with arc-shaped cross sections, and the ends of the first plug plate 501 and the second plug plate 502 that contact the inner surface of the sterile glove 3 are smooth arc chamfered.

[0085] The arc structure can prevent the sterile gloves from being scratched 3.

[0086] In some embodiments, the first inner support 805 and the second inner support 806 are provided with a parallel section 808 and a bent section 809. The parallel section 808 is parallel to the telescopic direction of the third telescopic rod 701. A freely rotating roller 807 is provided at one end of the parallel section 808, wherein arc chamfers are provided at the upper and lower ends of the parallel section 808 and the upper and lower end surfaces of the roller 807. The other end of the parallel section 808 is connected to the bent section 809 away from the sterile glove 3, and the bent section 809 is fixed on the slider 803.

[0087] The roller 807 is conducive to releasing the cuff 301 of the sterile glove 3. The arc chamfer can prevent the sterile glove 3 from being scratched. The parallel section 808 is convenient for inserting into the cuff 301 of the sterile glove 3, and the bent section 809 is conducive to limiting the depth of insertion into the cuff 301, preventing the insertion from being too deep, which makes it difficult to wear.

[0088] In some embodiments, a stopper 107 is provided at the bottom of the box 1 for limiting the position of the sterile tray 103 entering the interior. The sterile tray 103 can be guided to a preset position so that the suction cup 403 can be located just above the cuff 301 of the sterile glove 3.

[0089] In some embodiments, a liftable hand support plate 11 and a fourth telescopic rod 12 are provided on the inner side of the wearing hole 101. The fourth telescopic rod 12 is fixed on the inner wall of the box body 1 below the wearing hole 101. The hand support plate 11 is fixed to the upper end of the telescopic rod of the fourth telescopic rod 12. The cross-section of the hand support plate 11 is an arc shape.

[0090] The hand support plate 11 is used to place the forearm of the medical staff to prevent the forearm from moving around and affecting the auxiliary wearing process.

[0091] In some embodiments, a transparent window 105 for observing the internal wearing condition is sealed and fixed on the box body 1 above the wearing hole 101.

[0092] In some embodiments, the first telescopic rod 401 and the second telescopic rod 503 are both double-rod telescopic rods that are not rotatable. The double-rod telescopic rod will not rotate, and the operation is more stable and reliable.

[0093] In some embodiments, the wearing hole 101 and the tray opening 102 of the box body 1 are both provided with a sealing rubber plug for sealing a disposable sterile package.

[0094] In some embodiments, the device is provided with an emergency power-off switch 106 for disconnecting the power supply. The emergency power-off switch 106 is arranged on the top of the box 1 and can cut off the power supply to the device in an emergency, for example, in an emergency such as a program error or human error.

[0095] The operating principle of this device is as follows:

[0096] Step 1: Disinfect equipment.

[0097] 1. External disinfection of equipment: Use disinfectant, ultraviolet light and other disinfection methods to wipe and irradiate the exterior of the box 1, the wearing hole 101, and the tray opening 102 for disinfection. The specific steps are: place the equipment on a disinfected platform, first use disinfectant to repeatedly wipe and disinfect the six surfaces of the equipment (up, down, left, right, front and back); further use multiple ultraviolet lamps to irradiate all surfaces of the box 1 for 10-20 minutes.

[0098] 2. Internal disinfection of the equipment: The wearing hole 101 and the tray opening 102 of the box 1 are sealed with a sterile disposable sealing plug, and the built-in ozone generator 2 is turned on. Under the action of the high-voltage electric field of the ozone generator 2, the oxygen molecules in the air are ionized to form ozone molecules. Taking advantage of the strong penetration ability of ozone, the generated ozone gas disinfects all structures inside the box 1. The ozone concentration is usually controlled at 2 to 10 ppm, and the disinfection time is usually set at 15 to 60 minutes. After the disinfection is completed, the ozone absorption device is started to absorb excess ozone. The ozone absorption device includes a suction compressor and a compression tank. The suction compressor sucks the ozone inside the box 1 into the compression tank for storage. Ozone emissions basically do not pollute the atmosphere, but it is necessary to pay attention to monitoring the emission concentration. In a monitored and ventilated place, it can be slowly discharged to meet the standard. In addition, under the high-pressure condition of the compression tank, the stability of ozone is poor. High pressure will accelerate the decomposition reaction of ozone, and ozone will quickly convert into oxygen. After the compression tank is placed for a period of time, it will be discharged, which is conducive to reducing the ozone concentration and making it easier to meet the emission standards. The interior of the sterilized equipment is a sterile environment.

[0099] Step 2: Get ready.

[0100] 1. Hand13 cleaning: Before putting on sterile gloves3, medical staff must first wash their hands thoroughly13 in accordance with medical regulations.

[0101] 2. Prepare sterile gloves 3: Check the packaging of sterile gloves 3 and confirm that the packaging is intact.

[0102] 3. Place the sterile gloves 3 on the sterile tray 103: Place the sterile tray 103 in front of the sterilized equipment, open the packaging bag of the sterile gloves 3, remove the outer packaging, and place the sterile gloves 3 on the position marked 104 of the sterile tray 103 through the inner packaging paper. Push the sterile tray 103 into the equipment from the tray opening 102, so that the cuff 301 (folded part) of the sterile glove 3 is located directly below the suction cup 403.

[0103] Step 3: Assisted wearing.

[0104] 1. The suction cup 403 sucks up the sterile gloves 3 (such as Figure 5 , Figure 6 As shown): The suction cup 403 is extended downwards to the cuff 301 of the sterile glove 3 by the first telescopic rod 401, and negative pressure is generated at the suction cup 403 by the negative pressure system. The suction cup 403 adsorbs the cuff 301 of the sterile glove 3 (only contacts the inner surface of the sterile glove 3), and then the opening 302 of the cuff 301 of the sterile glove 3 is opened by the upward movement of the first telescopic rod 401, forming an opening 302 of the cuff 301 that is convenient for the vertical expansion mechanism 5 to be inserted.

[0105] 2. The cuff 301 of the sterile glove 3 expands vertically (e.g. Figure 7 , Figure 8 As shown in the figure): In the initial state, the first plug plate 501 and the second plug plate 502 are combined together, and the vertical expansion mechanism 5 is turned over above the suction cup 403. The vertical expansion mechanism 5 is rotated downward by the turning driving mechanism 6 until the first plug plate 501 and the second plug plate 502 are rotated together to the bottom of the suction cup 403 and inserted into the opening 302 of the cuff 301 of the sterile glove 3 (only contacting the inner surface of the sterile glove 3). Then, the second telescopic rod 503 is controlled to extend downward, so that the second plug plate 502 expands the opening 302 of the cuff 301 of the sterile glove 3 downward, until the opening 302 of the cuff 301 of the sterile glove 3 falls off the suction cup 403, and the first plug plate 501 and the second plug plate 502 completely prop up the opening 302 of the cuff 301 of the sterile glove 3 for the next lateral expansion, and at the same time, the sterile glove 3 is further lifted to the same horizontal position of the first inner support 805 and the second inner support 806 of the lateral expansion mechanism 8 through the first telescopic rod 401, so that the top ends of the first inner support 805 and the second inner support 806 are located below the horizontal line of the top of the cuff 301 of the sterile glove 3 after the vertical expansion (at least 3 mm below), and the bottom ends of the first inner support 805 and the second inner support 806 are located above the horizontal line of the bottom of the cuff 301 of the sterile glove 3 after the vertical expansion (at least 5 mm above).

[0106] 3. The cuff 301 of the sterile glove 3 expands laterally (e.g. Figure 9-13 shown):

[0107] (1) In the initial state, the transverse expansion mechanism 8 is in a retracted state (not invading the upper part of the sterile glove 3), and the first inner support 805 and the second inner support 806 on the transverse expansion mechanism 8 are symmetrically arranged with the vertical center line of the first plug plate 501 and the second plug plate 502 as the symmetry axis;

[0108] (2) The forward and reverse motor 804 of the lateral expansion mechanism 8 rotates forward, and the first inner support 805 and the second inner support 806 are simultaneously moved toward the center, so that the first inner support 805 and the second inner support 806 gradually enter the expansion range of the cuff 301 of the sterile glove 3;

[0109] (3) The third telescopic rod 701 translates the first inner support 805 and the second inner support 806 of the lateral expansion mechanism 8 into the folded cuff 301 of the sterile glove 3 (only contacting the outer surface of the sterile glove 3), and drives the first inner support 805 and the second inner support 806 to expand horizontally by reversing the forward and reverse motor 804 of the lateral expansion mechanism 8. At the same time, the second plug plate 502 of the vertical expansion mechanism 5 is controlled to be retracted upward until the first plug plate 501 and the second plug plate 502 are combined, and then the vertical expansion mechanism 5 is flipped upward by the flip driving mechanism 6 and withdrawn to the initial position. Finally, the folded part of the cuff 301 of the sterile glove 3 is propped up by the first inner support 805 and the second inner support 806, and the cuff 301 of the sterile glove 3 forms a rectangular opening 302 for the palm to be inserted into.

[0110] 4. Wear sterile gloves 3 (such as Figure 14-17 shown):

[0111] (1) While observing through the transparent window 105, the medical staff inserts the palm through the wearing hole 101 into the rectangular opening 302 of the cuff 301 of the sterile glove 3 (the hand 13 only touches the inner surface of the sterile glove 3), completes the donning of the five fingers, and sets the donning waiting time as needed (according to actual operation, most people can complete the donning of the five fingers within 10-30 seconds). During the donning waiting time, the device does not take any action. After the donning waiting time is over, the device proceeds to the next step.

[0112] (2) After the five-finger wearing waiting time is over, the third telescopic rod 701 is controlled to continue to extend. At this time, the first inner support 805 and the second inner support 806 continue to move along the wrist toward the cuff 10 of the sterile surgical gown 9, gradually pushing the folded part of the sterile glove 3 toward the cuff 10 of the sterile surgical gown 9, wherein the roller 807 plays a role in reducing friction, facilitating the rolling of the folded part of the cuff 301 of the sterile glove 3 turned outward. When the folded part of the cuff 301 of the sterile glove 3 is completely spread on the cuff 10 of the sterile surgical gown 9 by the first inner support 805 and the second inner support 806, and the cuff 301 of the sterile glove 3 tightens the cuff 10 of the sterile surgical gown 9, the lateral expansion mechanism 8 returns to the initial position, completing the auxiliary wearing of the sterile glove 3, and the hand that has been worn is slowly withdrawn from the wearing hole 101 without contact.

[0113] Step 4: The other hand assists in donning. Repeat the above step 3 to complete the other hand's sterile glove 3 assisting in donning from the other donning hole 101.

[0114] When any of the above steps needs to be stopped unexpectedly, the emergency power-off switch 106 can be pressed to cut off the power.
