Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a drainage tube with a clamping structure. Background Technology

[0002] A drainage tube is a medical device used in clinical surgery to drain pus, blood, and fluid accumulated between body tissues or in body cavities, preventing postoperative infection and promoting wound healing. During use, one end of the tube is inserted into the drainage site inside the body or wound, while the other end is externally connected to other external devices such as a drainage tube connector. Drainage is achieved through pressure from within the body, gravity, or negative pressure suction. Generally, when changing the drainage bottle in a closed thoracic drainage device, two soft round forceps are needed to clamp the lower end of the drainage tube above it to prevent air from entering the lungs. However, the forceps have a small contact area when clamping the drainage tube, which can easily damage it. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1 - Figure 4 A drainage tube with a clamping structure includes: a clamping component 1 and a sliding component 2;

[0031] Please see Figure 1 , Figure 3 The clamping assembly 1 includes a first clamping plate 101 and a second clamping plate 102. One side of the first clamping plate 101 and the second clamping plate 102 are connected to a movable arm 103. The two movable arms 103 are hinged together by a pin 104. Both ends of the pin 104 are fitted with torsion springs 105. One end of each of the two movable arms 103 is fixedly installed with a finger ring 106. The first clamping plate 101 and the second clamping plate 102 are rectangular strip designs.

[0032] In practical use: A movable arm 103 is connected to one side of the first clamping plate 101 and the second clamping plate 102. The two movable arms 103 are hinged together by a pin 104. Torsion springs 105 are sleeved at both ends of the pin 104. When it is necessary to clamp the drainage tube 3, the finger grips the ring 106 to drive the first clamping plate 101 and the second clamping plate 102 at one end of the movable arm 103 to the open and close state. The first clamping plate 101 and the second clamping plate 102 are placed on the surface of the drainage tube 3, and the ring is released. The rear torsion spring 105 drives the movable arm 103 to reset, so that the first clamping plate 101 and the second clamping plate 102 clamp and fix on the surface of the drainage tube 3, thus clamping the drainage tube 3. The first clamping plate 101 and the second clamping plate 102 adopt a rectangular strip design, and the clamping surface of the two clamping plates is flat. The drainage tube 3 is located in the middle of the clamping surface of the two clamping plates. Compared with the current round clamping method, the clamping plate increases the clamping area of ​​the drainage tube 3 after closing, achieving an effective clamping and closing effect.

[0033] Please see Figure 1 , Figure 4 The sliding component 2 includes an annular sliding sleeve 201 connected to one of the rings 106. The annular sliding sleeve 201 slides on the surface of the drainage tube 3. The inner wall of the annular sliding sleeve 201 is connected to a pressing plate 202, which contacts the outer wall of the drainage tube 3.

[0034] In practical use: the sliding component 2 includes an annular sliding sleeve 201 connected to the surface of the ring 106. The inner wall of the annular sliding sleeve 201 is connected to a pressing plate 202. The pressing plate 202 makes the annular sliding sleeve 201 contact the drainage tube 3. The annular sliding sleeve 201 slides on the surface of the drainage tube 3, so that the clamping position of the clamp can be adjusted.

[0035] Please see Figure 4 The annular sliding sleeve 201 has through holes 4 at both ends, and a locking screw 5 is inserted into the through hole 4. A fixing nut 6 is threaded to one end of the locking screw 5.

[0036] In practical use: the annular sliding sleeve 201 has through holes 4 at both ends, the locking screw 5 is inserted into the through holes 4, and the annular sliding sleeve 201 is tightened and fixed to the surface of the drainage tube 3 by tightening the fixing nut 6.

[0037] Please see Figure 2 , Figure 4 One end of the annular sliding sleeve 201 is connected to a connecting ring 7, and a spring buckle 8 is attached to the surface of the connecting ring 7. One end of the spring buckle 8 is connected to a connecting strap 9, and one end of the connecting strap 9 is connected to one of the finger rings 106.

[0038] In practical use: One end of the annular sliding sleeve 201 is connected to a connecting ring 7, and a spring buckle 8 is connected to the surface of the connecting ring 7. The spring buckle 8 is connected to one of the finger rings 106 through a connecting band 9 at one end, so that the clamping assembly 1 moves with the adjustment of the annular sliding sleeve 201.

[0039] Please see Figure 3 Anti-slip textures 10 are provided on both ends of the surfaces of the first clamping plate 101 and the second clamping plate 102.

[0040] In practical use: anti-slip textures 10 are provided at both ends of the surface of the first clamping plate 101 and the second clamping plate 102. When the clamping plate clamps the drainage tube 3, the anti-slip textures 10 can increase the friction with the drainage tube 3 and prevent the drainage tube 3 from sliding.

[0041] Please see Figure 3 The first clamping plate 101 and the second clamping plate 102 are made of polyester plastic.

[0042] In practical use: the first clamp 101 and the second clamp 102 are made of polyester plastic. Polyester plastic has high strength, good chemical corrosion resistance and water resistance. Compared with metal round clamps, clamps made of polyester plastic can avoid damage to the drainage tube 3.

[0043] Movable arms 103 are connected to one side of the first clamping plate 101 and the second clamping plate 102. The two movable arms 103 are hinged together by a pin 104. Torsion springs 105 are sleeved at both ends of the pin 104. When it is necessary to clamp the drainage tube 3, the fingers hold the ring 106 to drive the first clamping plate 101 and the second clamping plate 102 at one end of the movable arm 103 to be in an open or closed state. The first clamping plate 101 and the second clamping plate 102 are placed on the surface of the drainage tube 3. After releasing the ring 106, the torsion spring 105 drives the movable arm 103 to return to its original position, so that the first clamping plate 101 and the second clamping plate 102 are clamped and fixed to the drainage tube. The first clamping plate 101 and the second clamping plate 102 are rectangular strips with flat clamping surfaces. The drainage tube 3 is located in the middle of the clamping surfaces of the two clamping plates. Compared with the current round clamping method, the clamping plates increase the clamping area of ​​the drainage tube 3 after closing, achieving an effective clamping and closing effect. The first clamping plate 101 and the second clamping plate 102 are made of polyester plastic. Polyester plastic has high strength, good chemical corrosion resistance and water resistance. Compared with metal round clamps, the clamping plates made of polyester plastic can avoid damage to the drainage tube 3.
