Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pulling device for a blood-drawing pad. Background Art

[0002] Venous blood sampling is the most common method used in medicine to test patient body fluids and is also one of the most common invasive medical procedures. Each person uses a needle and a pressure cuff. The most easily overlooked issue is the hygiene of the blood collection pad. Blood collection pads can be roughly divided into disposable and non-disposable types. To avoid the risk of cross-infection, non-disposable protective blood collection pads are gradually being phased out. Existing disposable blood collection pads typically avoid cross-infection by placing a disposable blood collection towel on top of the blood collection pad.

[0003] Blood drawing pads are often placed between the table and the patient's arm to serve as an isolation during daily examinations or nursing to prevent liquid contamination of the pad and cross infection between the patient;

[0004] Existing blood-drawing pads are mostly laid directly on the tabletop when laying, and cannot be fixed after laying. Due to the material problem of the blood-drawing pad, it has poor anti-slip properties and is easy to fall after being placed, affecting its blood-drawing efficiency. Therefore, a pulling device for the blood-drawing pad is proposed. Utility Model Content

[0035] Example 2

[0036] like Figure 1-Figure 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the mounting mechanism 2 includes a fixing frame 21, the right side of the fixing frame 21 is fixedly connected to the left side of the placement block 1, a fixing frame 22 is fixedly provided on the front side of the fixing frame 21, a rotating rod 24 is rotatably provided on the inner front end surface of the fixing frame 22 through a bearing seat, the back side of the rotating rod 24 passes through the front side of the fixing frame 21 and extends to the inner side of the fixing frame 21, a threaded rod 27 is fixedly provided on the back side of the rotating rod 24, a pressing plate 25 is sleeved on the surface of the threaded rod 27, a nut 26 is fixedly provided on the back side of the pressing plate 25, and the nut The inner side surface of the nut 26 is threadedly connected to the surface of the threaded rod 27, and a gear 23 is fixedly sleeved on the surface of the rotating rod 24.

An extrusion block 212 is fixedly provided on the right side of the moving frame 211, and the surface of the extrusion block 212 is meshed with the tooth surface of the gear 23. A fixing plate 28 is fixedly provided on the top surface of the connecting sleeve 29, and a first spring 210 is fixedly provided on the left side of the fixed plate 28. The left side of the first spring 210 is fixedly connected to the inner left end surface of the moving frame 211.

[0037] In this embodiment, the towel roll can be installed and fixed by providing an installation mechanism 2. After the installation and fixation is completed, the squeezing block 212 can be squeezed to the right by providing a first spring 210. When the squeezing block 212 is squeezed to the right, it can engage with the gear 23, thereby generating resistance to the gear when it rotates, so that the towel can be in a taut state when it is pulled out.

[0038] When in use, the towel roll is sleeved on the surface of the rotating rod 24, and the pressing plate 25 is sleeved on the surface of the rotating rod 24. The pressing plate 25 can be moved backward by rotating the nut 26. When the pressing plate 25 moves backward, the back of the towel sleeve can be squeezed to fix it. One end of the towel is pulled out so that the towel is laid on the placement block 1. After the towel is pulled out, the rotating rod 24 can be rotated. When the rotating rod 24 rotates, it can drive the gear 23 to rotate. The squeezing block 212 can be squeezed to the right side by the first spring 210. When the squeezing block 212 is squeezed to the right side, it can mesh with the gear 23, so that resistance can be generated to the gear when it rotates, so that the towel can be in a taut state when it is pulled out. After the pulling out is completed, the surface of the towel is aligned with the placement block 1 right side contact, the extrusion frame 36 is manually controlled to move forward, and the insertion rod 38 can be disengaged from the slot when the extrusion frame 36 moves forward, and the extrusion plate 32 can be squeezed to the left by the elastic member 313. When the extrusion plate 32 moves to the left, it can squeeze the surface of the pad, and thus fix it. When the pad needs to be replaced, it is only necessary to manually control the extrusion plate 32 to move to the right. When the extrusion plate 32 moves, it can drive the limiting frame 310 to move synchronously with the slot on its surface. When the slot position corresponds to the position of the insertion rod 38, the second spring 37 can be used to insert the insertion rod 38 into the inner wall of the slot, and thus the extrusion plate 32 can be fixed. The pad can be replaced by pulling it, and when the pad needs to be fixed, it is only necessary to repeat the above operation.

[0039] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
