Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a needle recycling device. Background Art
[0002] Hemodialysis is a method for treating renal failure, which uses a machine or an artificial dialyzer to remove waste products, salts and excess water from the blood. When the renal function is damaged and cannot effectively filter waste products and fluids from the blood, hemodialysis is required. During hemodialysis, the patient's blood is drawn out, processed by the dialyzer and then returned to the body to remove the accumulated waste products and water in the body and maintain the body's physiological balance.
[0003] When removing the needle after hemodialysis, it is necessary to recycle this disposable needle. The existing sharps container is provided with a handle for hanging on the treatment cart. However, due to the relatively small space around the hospital bed, it is not convenient to push the treatment cart in, and there are generally medical supplies and patients' daily necessities placed on the bedside table beside the hospital bed, making it inconvenient to place the sharps container. If the sharps container is placed on the hospital bed, it is likely to tip over, making the recycling of the needle rather inconvenient.
[0004] Moreover, the sharps container needs to be replaced when it is three-quarters full. In actual use, it is difficult for medical staff to control the capacity, and there is a potential risk of being stabbed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a needle recycling device that is convenient to carry and use and can ensure the safe recycling of needles.
[0006] To achieve the above purpose, the technical solution of the utility model is as follows.
[0007] A needle recycling device includes a sharps container. A feeding port is opened on the upper surface of the sharps container. A baffle is slidably installed below the feeding port inside the sharps container, and a push block is installed on the upper surface of the baffle. Tooth plates are installed on both sides of the lower surface of the baffle in the length direction. Gears are rotatably installed on both inner walls of the sharps container, and the gears are meshed with the tooth plates. A connecting shaft is connected between the two gears, and a partition plate is installed on the outer surface of the connecting shaft. Two side blocks are installed on one side of the upper surface of the sharps container away from the feeding port. Circular blocks are rotatably installed on the opposite surfaces of the two side blocks. An L-shaped vertical rod is rotatably installed between the two circular blocks, and a handle is installed at the end of the L-shaped vertical rod. Two positioning holes are opened on the outer surface of the circular block, and the included angle between the two positioning holes is 90 degrees. A fixing mechanism capable of being inserted and matched with the positioning holes is arranged on the outside of the side block.
[0008] It can be seen that through the meshing relationship between the gear and the toothed plate, when the baffle is opened, it will drive the partition plate to turn to the horizontal state. At this time, the partition plate separates the needles inside the sharps container from the feeding port, thereby avoiding the risk of the needles inside the sharps container stabbing medical staff when the needles are put in, ensuring the safe recycling of the needles. And when the needles inside the sharps container are filled to three-quarters, the partition plate will be blocked when it turns, and thus the needles cannot be continuously put into the sharps container, realizing the automatic control of the needle feeding amount, with higher safety. Through the plug-in cooperation between the fixing mechanism and the positioning holes, the L-shaped vertical rod can be fixed in the vertical state or the horizontal state. When in the vertical state, the L-shaped vertical rod and the handle can be hung on the hospital bed guardrail. When in the horizontal state, the handle can be grasped to carry the sharps container, which is convenient for carrying and placing for use.
[0009] Further, the fixing mechanism includes a tube body installed on the outer surface of the side block. An insertion rod is inserted into the interior of the tube body, and the end of the insertion rod is in plug-in cooperation with the positioning hole. A shoulder is arranged on the outer surface of the insertion rod, and a first spring is sleeved on the outer surface of the insertion rod. The two ends of the first spring are respectively abutted against the shoulder and the inner wall of the tube body.
[0010] By pulling the insertion rod outwards so that its end is withdrawn from the positioning hole, the fixation of the L-shaped vertical rod can be cancelled, and then the L-shaped vertical rod can be turned. When the L-shaped vertical rod is turned to the vertical or horizontal angle, the insertion rod can be inserted into the corresponding positioning hole to realize the fixation of the L-shaped vertical rod, and under the elastic force of the first spring, the stability of the L-shaped vertical rod in the fixed state can be ensured.
[0011] Further, a finger ring is installed at the end of the insertion rod away from the positioning hole.
[0012] Through the setting of the finger ring, it is convenient to pull the insertion rod outwards.
[0013] Further, a fixing block is installed on the top wall of the sharps container. A guide rod is connected to the outer surface of the baffle, and the guide rod penetrates through the interior of the fixing block. A second spring is sleeved on the outer surface of the guide rod. The two ends of the second spring are respectively abutted against the fixing block and the baffle.
[0014] Through the elastic force of the second spring, it always exerts a thrust on the baffle, thereby improving the sealing performance of the baffle for the feeding port, and avoiding the situation that the baffle is forgotten to be closed, and preventing blood from splashing out and polluting the environment.
[0015] Further, a limiting groove is formed on the surface of the L-shaped vertical rod, and the limiting groove is adapted to the pushing block.
[0016] When the sharps container is not in use, the L-shaped vertical rod can be fixed in the horizontal state. At this time, the pushing block is inside the limiting groove, and the purpose of locking the baffle can be achieved to prevent accidental opening. When the sharps container is in use, the L-shaped vertical rod can be fixed in the vertical state and hung on the hospital bed guardrail. At this time, the baffle is unlocked and can be used.
[0017] Furthermore, a rubber pad is provided on the outer surface of the grip, and anti-slip lines are provided on the surface of the rubber pad.
[0018] Through the arrangement of the rubber pad and the anti-slip lines, the friction force on the surface of the grip can be increased, and the situation of sliding can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The present utility model will be described in detail below with reference to the accompanying drawings.
[0027] As Figures 1-6As shown in the figure, a needle recycling device includes a sharp container 100. The upper surface of the sharp container 100 is provided with a feeding port 101. A baffle 102 is slidably installed inside the sharp container 100 below the feeding port 101. A push block 103 is installed on the upper surface of the baffle 102. Tooth plates 104 are installed on both sides of the lower surface of the baffle 102 in the length direction. Gear 105 is rotatably installed on both inner walls of the sharp container 100, and the gear 105 is meshed with the tooth plate 104. A connecting shaft 106 is connected between the two gears 105. A partition plate 107 is installed on the outer surface of the connecting shaft 106. Two side blocks 108 are installed on one side of the upper surface of the sharp container 100 away from the feeding port 101. Round blocks 109 are rotatably installed on the opposite surfaces of the two side blocks 108. An L-shaped vertical rod 110 is rotatably installed between the two round blocks 109. A handle 111 is installed at the end of the L-shaped vertical rod 110. Two positioning holes 112 are provided on the outer surface of the round block 109, and the included angle between the two positioning holes 112 is 90 degrees. A fixing mechanism 200 capable of being inserted and matched with the positioning hole 112 is arranged outside the side block 108.
[0028] When carrying the sharp container 100, the fixing of the L-shaped vertical rod 110 can be cancelled by the insertion and matching of the fixing mechanism 200 and the positioning hole 112. After the L-shaped vertical rod 110 is turned to the horizontal state, it can be fixed by the fixing mechanism 200. At this time, medical staff can hold the handle 111 to carry the sharp container 100. When the medical staff carry the sharp container 100 to the bedside, the L-shaped vertical rod 110 can be fixed in the vertical state by using the above operation. Then, the handle 111 and the L-shaped vertical rod 110 can be hung on the hospital bed guardrail for placement and use. When recycling the needle, the push block 103 can be pushed to drive the baffle 102 to open. Due to the meshing relationship between the tooth plate 104 and the gear 105, when the baffle 102 is opened, the partition plate 107 is in the horizontal state. Medical staff can put the needle into the feeding port 101 and it will fall on the surface of the partition plate 107. Then the baffle 102 is closed. During the closing process of the baffle 102, the partition plate 107 is turned from the horizontal state to the vertical state. At this time, the needle on the surface of the partition plate 107 can fall into the sharp container 100, achieving the purpose of needle recycling and having higher safety.
[0029] Specifically, the fixing mechanism 200 includes a tube body 201 installed on the outer surface of the side block 108. A plug rod 202 is inserted into the interior of the tube body 201, and the end of the plug rod 202 is inserted and fitted with the positioning hole 112. A shoulder 203 is arranged on the outer surface of the plug rod 202. A first spring 204 is sleeved on the outer surface of the plug rod 202. The two ends of the first spring 204 are respectively abutted against the shoulder 203 and the inner wall of the tube body 201. By pulling the plug rod 202 outwards to make its end part withdraw from the positioning hole 112, the fixation of the L-shaped vertical rod 110 can be cancelled, so that the L-shaped vertical rod 110 can be turned over. When the L-shaped vertical rod 110 is turned over to a vertical or horizontal angle, the plug rod 202 can be inserted into the corresponding positioning hole 112 to realize the fixation of the L-shaped vertical rod 110. And under the elastic force of the first spring 204, the stability of the L-shaped vertical rod 110 in the fixed state can be ensured.
[0030] Specifically, a finger ring 300 is installed at the end of the plug rod 202 away from the positioning hole 112. Through the arrangement of the finger ring 300, it is convenient to pull the plug rod 202 outwards.
[0031] Specifically, a fixing block 400 is installed on the top wall of the sharp instrument box 100. A guide rod 401 is connected to the outer surface of the baffle 102, and the guide rod 401 penetrates through the interior of the fixing block 400. A second spring 402 is sleeved on the outer surface of the guide rod 401. The two ends of the second spring 402 are respectively abutted against the fixing block 400 and the baffle 102. Under the elastic force of the second spring 402, it always exerts a thrust on the baffle 102, thereby improving the sealing performance of the baffle 102 for the feeding port 101, and avoiding the situation that the baffle 102 is forgotten to be closed, and preventing blood from splashing out and polluting the environment.
[0032] Specifically, a limiting groove 500 is formed on the surface of the L-shaped vertical rod 110, and the limiting groove 500 is adapted to the push block 103. When the sharp instrument box 100 is not in use, the L-shaped vertical rod 110 can be fixed in a horizontal state. At this time, the push block 103 is located inside the limiting groove 500, and the purpose of locking the baffle 102 can be achieved to prevent accidental opening. When the sharp instrument box 100 is in use, the L-shaped vertical rod 110 can be fixed in a vertical state and hung on the guardrail of the hospital bed. At this time, the baffle 102 is unlocked and can be used.
[0033] Specifically, a rubber pad is arranged on the outer surface of the handle 111, and anti-slip lines are formed on the surface of the rubber pad. Through the arrangement of the rubber pad and the anti-slip lines, the friction force on the surface of the handle 111 can be increased, and the situation of slipping can be reduced.
[0034] The above is a detailed description of the present utility model in conjunction with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, all of which should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
