Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an automatic cotton swab pasting device for the needle hole part in vaccine inoculation care. Background Technique

[0002] Vaccine inoculation is a technique of inoculating vaccine preparations into humans or animals. After inoculation into the body, it enables the recipient to obtain immunity against a specific pathogen or a pathogen similar to the vaccine. By the immune system's recognition of foreign substances, antibody screening and production are carried out to produce antibodies against the pathogen or a similar pathogen, thereby enabling the vaccinated person to have a stronger resistance to the disease. It is a general term for biological products that can enable the body to develop immunity to specific diseases. Vaccine inoculation is the most important and effective means of preventing infectious diseases and an important measure to eliminate or control infectious diseases.

[0003] After vaccine inoculation, medical staff will give the vaccinated person a cotton swab and ask the vaccinated person to press the cotton swab on the needle hole of the inoculated vaccine for five minutes. If there is no bleeding, it will be okay, thus achieving the effect of compressing and stopping bleeding, avoiding subcutaneous blood flowing out from the needle hole, resulting in local bleeding or subcutaneous congestion, and affecting the vaccination experience of the vaccinated person.

[0004] However, in the actual use of the above device, during the pressing process, the vaccinated person needs to use the other arm to press the cotton swab on the needle hole. If the vaccinated person loosens the cotton swab during the pressing process, there may be a situation of local bleeding or subcutaneous congestion. Therefore, the vaccinated person cannot loosen the cotton swab, resulting in the vaccinated person being unable to release the arm for other operations, which is time-consuming and laborious. In view of this, we have proposed an automatic cotton swab pasting device for the needle hole part in vaccine inoculation care. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic cotton swab pasting device for the needle hole part in vaccine inoculation care to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An automatic cotton swab pasting device for the needle hole part in vaccine inoculation care, including a wearable sleeve that can be worn on the arm of the vaccinated person so that the automatic pasting mechanism can work. A placement groove is opened at the center of the upper surface of the wearable sleeve, and a cotton swab body is arranged inside the placement groove. An automatic pasting mechanism is arranged above the wearable sleeve, and the automatic pasting mechanism includes:

[0007] A U-shaped fixing frame is fixedly installed at the center of the upper surface of the wearable sleeve. A fixing rod is fixedly installed inside the U-shaped fixing frame, and a rotating long plate is rotatably installed on the outer side of the fixing rod, and the rotating long plate can rotate around the fixing rod;

[0008] The pressing plate is fixedly installed on the back surface of the rotating long plate. An arc-shaped pressing groove is formed on the bottom surface of the pressing plate. When the rotating long plate rotates, it can drive the pressing plate to move synchronously.

Detailed implementation manners

[0029] As Figures 1-5 shown, the present invention provides a technical solution: an automatic pasting device for the cotton swab at the needle hole part for vaccine inoculation care, including a wearing sleeve 1, the wearing sleeve 1 is composed of an upper fixing sleeve, a lower fixing sleeve and a fixing member, the upper fixing sleeve and the lower fixing sleeve are hinged and can be turned over to open and close, and can be fixed by the fixing member after closing. When the wearing sleeve 1 is worn on the arm of the inoculated person, the automatic pasting mechanism 5 can be operated to make the cotton swab body 4 fit the needle hole on the arm of the inoculated person, press the needle hole to avoid bleeding. A placement groove 3 is opened at the center of the upper surface of the wearing sleeve 1, the cotton swab body 4 is arranged inside the placement groove 3, and an automatic pasting mechanism 5 is arranged above the wearing sleeve 1.

[0030] The automatic pasting mechanism 5 includes: a U-shaped fixing frame 501, a pressing plate 504, a support frame 506 and a limiting rod 511. The U-shaped fixing frame 501 is fixedly installed at the center of the upper surface of the wearing sleeve 1. A fixing rod 502 is fixedly installed inside the U-shaped fixing frame 501. A rotating long plate 503 is rotatably installed on the outer side of the fixing rod 502. The rotating long plate 503 can rotate in the up and down direction around the fixing rod 502. The pressing plate 504 is fixedly installed on the back surface of the rotating long plate 503. When the rotating long plate 503 moves, it can drive the pressing plate 504 to rotate synchronously. An arc-shaped pressing groove 505 is formed on the bottom surface of the pressing plate 504. Circular grooves are formed at both the front and rear ends of the upper surface of the arc-shaped pressing groove 505, which can reduce the situation that the cotton swab body 4 is bent due to the scraping and movement between the pressing plate 504 during rotation and the cotton swab body 4. The size of the arc-shaped pressing groove 505 is adapted to the size of the cotton swab body 4. When the pressing plate 504 moves above the cotton swab body 4 and the cotton swab body 4 enters the inside of the arc-shaped pressing groove 505 and fits with the inner wall of the arc-shaped pressing groove 505, the pressing plate 504 can limit the cotton swab body 4. When the pressing plate 504 receives a downward extrusion force, it will transmit the force to the cotton swab body 4, so that the rear end of the cotton swab body 4 is closely attached to the needle hole on the arm of the vaccinated person to press the needle hole to avoid blood return.

[0031] The support frame 506 is fixedly installed at the front end of the upper surface of the wearing sleeve 1. A rotating circular block 507 is arranged above the support frame 506. The support frame 506 can limit and support the movement of the adjusting screw 508. An adjusting screw 508 is fixedly installed on the bottom surface of the rotating circular block 507. When the rotating circular block 507 rotates, it can drive the adjusting screw 508 to rotate synchronously. The bottom end of the adjusting screw 508 penetrates through the upper surface of the support frame 506 and is rotatably installed with a connecting plate 509. A spring 510 is fixedly installed on the bottom surface of the connecting plate 509. The bottom end of the spring 510 is fixedly connected to the upper surface of the rotating long plate 503. When the connecting plate 509 moves in the up and down direction, it can drive the spring 510 to move synchronously, so as to adjust the pressing force of the pressing plate 504 on the cotton swab body 4. The limiting rod 511 is fixedly installed on the inner bottom surface of the support frame 506. The bottom end of the limiting rod 511 penetrates through the upper surface of the connecting plate 509. The limiting rod 511 can guide and limit the movement of the connecting plate 509, so that the connecting plate 509 can only move in a straight line in the up and down direction. When the adjusting screw 508 rotates and moves downward, it can drive the connecting plate 509 to move downward synchronously without rotation.

[0032] On the left inner wall surface of the placement groove 3, a fixing groove 601 is provided. Inside the fixing groove 601, a moving plate 602 is arranged. The outer wall of the moving plate 602 is in mutual fit with the inner wall of the fixing groove 601. The inner wall of the fixing groove 601 can guide and limit the movement of the moving plate 602. A limiting nail 603 is fixedly installed at the right end of the moving plate 602. When the moving plate 602 moves, the limiting nail 603 can be driven to move synchronously. A fixing screw 604 is rotatably installed on the left surface of the moving plate 602. The left end of the fixing screw 604 penetrates through the left inner wall surface of the fixing groove 601 and is fixedly installed with a rotating circular plate 605. Rotating the rotating circular plate 605 can drive the fixing screw 604 to rotate. When the fixing screw 604 rotates, a linear motion in the left-right direction can be carried out. Thus, under the limitation of the inner wall of the fixing groove 601, the moving plate 602 can be driven to perform a linear motion in the left-right direction. When the moving plate 602 moves to the right and drives the limiting nail 603 into the placement groove 3, the limiting nail 603 can be inserted into the cotton swab body 4 placed inside the placement groove 3, thereby fixing and limiting the cotton swab body 4, and avoiding the displacement of the cotton swab body 4 due to the movement of the inoculator's arm during the pressing process, which affects the pressing effect.

[0033] At the rear end of the upper surface of the wearing sleeve 1, a sliding groove 701 is provided. Inside the sliding groove 701, a sliding block 702 is slidably connected. The sliding block 702 can slide in the left-right direction inside the sliding groove 701. The right surface of the sliding block 702 and the left surface of the rotating long plate 503 are on the same horizontal line. When the rotating long plate 503 rotates downward to drive the pressing plate 504 to press the cotton swab body 4, the rotating long plate 503 can limit the sliding block 702, avoiding the shaking and impact of the sliding block 702 on the rotating long plate 503 during the use of the automatic pasting mechanism 5, which affects the use effect of the device. A clamping groove 703 is provided on the upper surface of the sliding block 702. A clamping bar 704 is fixedly installed on the bottom surface of the rotating long plate 503. The size of the clamping groove 703 is mutually adapted to the size of the clamping bar 704. When it is necessary to remove the cotton swab body 4 after the automatic pasting mechanism 5 is used, the pressing plate 504 can be rotated upward to separate from the cotton swab body 4, and then the sliding block 702 is moved to the rightmost end of the sliding groove 701. At this time, the clamping groove 703 is located directly below the clamping bar 704. After releasing the pressing plate 504, the rotating long plate 503 will move downward under the elastic potential energy of the spring 510, so that the clamping bar 704 enters the clamping groove 703, avoiding the obstruction of the pressing plate 504 when taking or placing the cotton swab body 4.

[0034] In the present invention, during use, the pressing plate 504 is lifted upward to compress the spring 510 to generate elastic potential energy. After moving the slider 702 to the rightmost end of the sliding groove 701, the pressing plate 504 is released, so that the clamping bar 704 enters the inside of the clamping groove 703 to limit the rotation of the long plate 503 and the pressing plate 504, avoiding the pressing plate 504 from hindering the placement of the cotton swab body 4. When the cotton swab body 4 is placed in the placement groove 3, the pressing plate 504 is lifted again to release the limit of the slider 702 on the rotating long plate 503, and the slider 702 is moved to the leftmost end of the sliding groove 701. Then the pressing plate 504 is released, so that the rotating long plate 503 moves downward under the action of the elastic potential energy of the spring 510, so that the cotton swab body 4 enters the inside of the arc-shaped pressing groove 505, and the pressing plate 504 will perform preliminary limitation on the cotton swab body 4. At this time, the medical staff can wear the wearing sleeve 1 on the upper arm of the vaccinated person, so that the cotton swab body 4 fits against the needle eye of the vaccinated person. After fixing the wearing sleeve 1, the rotating circular block 507 is rotated, and the spring 510 is driven to perform a linear motion in the up and down directions through the cooperation of the adjusting screw 508, the connecting plate 509 and the limiting rod 511, and then the pressing force of the cotton swab body 4 against the needle eye of the vaccinated person's arm is adjusted through the cooperation of the rotating long plate 503 and the pressing plate 504, avoiding blood return caused by too small a force or affecting the vaccination experience of the vaccinated person due to too large a pressing force. After the adjustment is completed, the rotating circular plate 605 can be rotated, and the limiting nail 603 is driven into the inside of the placement groove 3 and inserted into the inside of the cotton swab body 4 through the cooperation of the fixing screw 604, the moving plate 602 and the inner wall of the fixing groove 601 to fix and limit the cotton swab body 4, avoiding the displacement of the cotton swab body 4 due to the movement of the vaccinated person's arm during the pressing process. At this time, the cotton swab body 4 will be pressed against the needle eye by the pressing plate 504, thus liberating the hands of the vaccinated person and the operation is simple. When the cotton swab body 4 is used up, the pressing plate 504 can be lifted repeatedly, and the clamping bar 704 is clamped into the clamping groove 703 to perform clamping and limiting on the pressing plate 504, avoiding the pressing plate 504 from affecting the taking of the cotton swab body 4.

[0035] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
