Description

Technical Field

[0001] This utility model belongs to the technical field of extubation medical tubing devices, specifically relating to a portable extubation auxiliary tool. Background Technology

[0002] Some patients with chronic diseases have drainage tubes inserted, connected to drainage bags. When these patients return home with drainage tubes, the drainage bags need to be changed during home care. Because the connection between the drainage tube and the drainage bag is very secure, it is difficult to separate the drainage bag from the tube by hand. Therefore, tools are needed to assist in removing the drainage bag. A common method is to use sterile gauze to increase friction and separate the drainage tube and drainage bag. However, even sterile gauze cannot easily separate the drainage bag from the tube, making the operation quite difficult. Using forceps to clamp the drainage bag from the tube may damage both the drainage bag and the tube, making this method unsuitable. Summary of the Invention

[0003] This invention addresses the drawback of existing technologies where drainage bags and drainage tubes are difficult to separate by providing a portable tube removal tool. Using this tool, the drainage bag and drainage tube can be separated more easily. It is convenient to use, easy to carry, and less likely to damage the drainage tube and drainage bag.

[0004] The objective of this invention is achieved through the following technical solution: a portable tube removal auxiliary tool, comprising two mutually cooperating clamping units and a connector for connecting the two clamping units and keeping the two clamping units in a separated state. The two clamping units cooperate to form a clamping channel for the passage of a flexible tube. The clamping channel includes at least two continuously arranged curved channel units, with adjacent channel units having opposite bending directions. The inner diameter of the clamping channel is smaller than the outer diameter of the flexible tube.

[0005] Preferably, the inner wall of the clamping channel is provided with anti-slip protrusions.

[0006] Preferably, the clamping unit includes a base, on which fixed teeth are fixedly provided. The fixed teeth on the two clamping units are staggered, and the surface of the fixed teeth is provided with grooves. When the two clamping units cooperate with each other, the grooves on the fixed teeth are joined together to form the clamping channel.

[0007] Preferably, the anti-slip protrusion is fixedly disposed at the bottom of the groove.

[0008] Preferably, the anti-slip protrusions are arc-shaped and distributed along the length of the groove.

[0009] Preferably, the connector is an elastic telescopic structure, specifically including a hollow guide jacket, an inner rod slidably disposed inside the guide jacket, and a drive spring disposed inside the guide jacket for driving the inner rod to extend outward at one end of the guide jacket. A clamping unit is fixedly connected to both the guide jacket and the inner rod; the guide jacket and the inner rod are made of medical-grade plastic.

[0010] Preferably, the guide jacket is provided with a retaining plate that is fixedly connected to the inner rod, and the guide jacket is also fixed with a baffle to prevent the retaining plate from falling out of the jacket.

[0011] Preferably, a magnetic sheet is fixedly provided on the guide jacket.

[0012] Preferably, the connector is a V-shaped connecting spring, with a clamping unit fixedly connected to each end of the connecting spring.

[0013] Preferably, the clamping unit is made of medical-grade plastic.

[0014] Compared with the prior art, the present invention has the following advantages: the present invention is used to assist in removing the tubing, making the removal of the tubing easier and without damaging the medical tubing.

[0015] 1. The portable tube removal tool of this application clamps the tube by continuously bending it in the opposite direction, which can firmly clamp the tube and make it easier to separate the drainage tube from the drainage bag.

[0016] 2. The anti-slip protrusions enhance the friction between the auxiliary tool and the hose, making it less likely for the drainage tube and the auxiliary tool to slip relative to each other when using the auxiliary tool to separate the drainage tube and drainage bag.

[0017] 3. The part of the auxiliary tool that comes into contact with the hose has no sharp structure and will not damage the hose.

[0018] 4. This auxiliary tool is small in size and easy to carry. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0026] Example 1

[0027] like Figures 1-3 As shown, a portable tube removal aid includes two cooperating clamping units 1 and a connector 2 for connecting the two clamping units 1 and keeping them separated. Each clamping unit 1 includes a base 3 with fixing teeth 4 fixedly mounted on it. The fixing teeth 4 on the two clamping units 1 are staggered, and the surfaces of the fixing teeth 4 have grooves 5. When the two clamping units 1 cooperate, the grooves 5 on the fixing teeth 4 cooperate to form a clamping channel 6 through which the tube passes. The clamping channel 6 includes at least two continuously arranged curved channel units 7, with adjacent channel units 7 bending in opposite directions. The inner diameter of the clamping channel 6 is smaller than the outer diameter of the tube. In this embodiment, one clamping unit 1 has two fixing teeth 4, and the other clamping unit 1 has one fixing tooth 4. The fixing teeth 4 have no sharp structures.

[0028] To reduce the possibility of relative slippage between the hose and the clamping channel 6 during use, anti-slip protrusions 8 are fixedly provided on the inner wall of the clamping channel 6, that is, anti-slip protrusions 8 are fixedly provided at the bottom of the groove 5. The anti-slip protrusions 8 have an arc-shaped structure and are distributed along the length of the groove 5.

[0029] The connector 2 is an elastic telescopic structure, specifically including a hollow guide jacket 9, an inner rod 10 slidably disposed inside the guide jacket 9, and a drive spring 11 disposed inside the guide jacket 9 for driving the inner rod 10 to extend outward at one end of the guide jacket 9. A clamping unit 1 is fixedly connected to both the guide jacket 9 and the inner rod 10. A clamping plate 12 fixedly connected to the inner rod 10 is disposed inside the guide jacket 9, and a baffle 13 fixedly disposed on the guide jacket 9 to prevent the clamping plate 12 from detaching from the jacket.

[0030] The guide jacket 9, inner rod 10, and clamping unit 1 are all made of sterilizable medical plastic, which meets the standards for use of medical supplies.

[0031] Sometimes it is necessary to use two sets of portable tube removal auxiliary tools at the same time. In order to facilitate the carrying of the two sets of auxiliary tools, a magnetic sheet 14 is fixedly installed on the guide sleeve 9. The two sets of auxiliary tools can be attracted together by the magnetic attraction between the magnetic sheets 14.

[0032] like Figure 4 As shown, when using this portable tube removal tool, place the drainage tube between the two clamping units 1 and position the drainage tube in the groove 5. Hold the two clamping units 1 firmly. During this process, because the inner diameter of the clamping channel 6 is smaller than the outer diameter of the tube, the two clamping ends themselves have a certain clamping effect on the drainage tube. At this time, the drainage tube is located in the clamping channel 6 formed by the groove 5 and is continuously bent in the opposite direction. With the anti-slip protrusions 8, the portable tube removal tool can firmly clamp the drainage tube and other tubes. At this time, by pulling the drainage tube and drainage bag in opposite directions, the drainage bag and drainage tube can be separated relatively easily. When the length of the tube on the drainage bag is long enough to be clamped by the portable tube removal tool, another portable tube removal tool can also be used to clamp the tube on the drainage bag. Hold the two portable tube removal tools with both hands and pull them forcefully to separate the drainage bag and drainage tube relatively easily.

[0033] Example 2

[0034] like Figure 5 As shown, compared with Embodiment 1, the difference in Embodiment 2 is that the connecting member 2 is a V-shaped connecting spring 15, with a clamping unit 1 fixedly connected to each end of the connecting spring 15. Compared with Embodiment 1, the connecting member 2 in this embodiment has a simpler structure, which is beneficial for reducing production costs, but it is not conducive to the motion guidance when the two clamping units 1 are clamped together.
