Technical Field

[0001] The utility model relates to the field of drainage tube auxiliary devices, in particular to a drainage tube end anti-bending device. Background Art

[0002] The purpose of placing a drainage device after thyroid and breast surgery is to prevent blood and fluid accumulation in the wound, monitor the amount of bleeding in the wound, and prevent hematoma from compressing the tissue around the wound. A variety of drainage devices can be used after surgery. The most commonly used one is a drainage device that combines a disposable one-way negative pressure ball with a drainage tube with continuous negative pressure suction.

[0003] In clinical practice, when patients turn over, get out of bed and place the drainage ball in their pocket, they often accidentally fold the drainage tube; the folded drainage tube cannot remain unobstructed and cannot achieve effective drainage; at the same time, when the drainage tube is folded, the patient's drainage cannot be dynamically observed, which hinders the doctor's judgment and diagnosis. Utility Model Content

[0004] The purpose of the utility model is to provide a drainage tube end anti-bending device to solve the defects mentioned in the above background technology.

[0005] To achieve the above object, a drainage tube end anti-bending device is provided, comprising a negative pressure ball, a sealing cover is screwed and fixed on the surface of the negative pressure ball, and a drainage tube body is densely installed on the sealing cover, and the connection between the drainage tube body and the sealing cover is limited by the anti-bending device body; a mounting port is provided on the surface of the sealing cover;

[0006] The anti-folding device body includes a limiting spring, and the bottom of the limiting spring is fixedly connected to the mounting plate. At the same time, the bottom of the mounting plate is fixedly connected to the fixing tube, and the end of the fixing tube away from the mounting plate is fixed to the limiting plate, and the limiting plate covers the surface of the sealing cover.

[0007] Preferably, the limit spring is wrapped around the outside of the drainage tube body, and the cross-section of the limit spring and the drainage tube body is a concentric circle structure.

[0008] Preferably, the diameter of the limit spring is 6 mm, and the diameter of the drainage tube body is 5-6 mm, and at the same time, the upper part of the drainage tube body is limited by the limit spring, and the lower part of the drainage tube body is limited by the fixing tube.

[0009] Preferably, the cross-sections of the mounting plate, the fixing tube and the limiting plate are arranged in an I-shape, and an inner liner is fixedly arranged on the inner wall surface of the fixing tube, while the fixing tube is wrapped around the bottom of the drainage tube body by the inner liner.

[0010] Preferably, the bottom of the limiting plate is fixedly connected to the sealing plug, and the sealing plug is an original tubular structure made of rubber material. At the same time, the sealing plug is interference fit with the installation port, and the sealing plug is inserted into the inside of the installation port.

[0011] Preferably, the outer side of the limit spring is evenly covered with a layer of transparent dressing, and the length of the limit spring is greater than the length of the fixing tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The limit spring prevents the drainage tube from bending above the root, so as to prevent the connection between the drainage tube and the negative pressure ball from bending when the patient gets up and turns over. The drainage tube can remain unobstructed when the patient moves, so as to achieve effective drainage. At the same time, it can prevent the drainage of the patient from being dynamically observed when the drainage tube is bent, which would hinder the doctor's judgment and diagnosis.

[0014] In order to prevent the limit spring from causing pressure marks on the patient's skin when the patient is resting in bed, a layer of transparent dressing is wrapped on the outer surface of the limit spring. This can not only reduce the pressure marks on the skin, but also allow the drainage fluid at the end of the drainage tube to be observed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] See also Figure 1-3 The utility model provides a drainage tube end anti-bending device, comprising a negative pressure ball 1, a sealing cover 2 is screwed and fixed on the surface of the negative pressure ball 1, and a drainage tube body 4 is densely installed on the sealing cover 2, and the connection between the drainage tube body 4 and the sealing cover 2 is limited by an anti-bending device body 5; a mounting port 3 is provided on the surface of the sealing cover 2;

[0020] The anti-folding device body 5 includes a limiting spring 51, and the bottom of the limiting spring 51 is fixedly connected to the mounting plate 52. At the same time, the bottom of the mounting plate 52 is fixedly connected to the fixing tube 53, and the end of the fixing tube 53 away from the mounting plate 52 is fixed to the limiting plate 55, and the limiting plate 55 covers the surface of the sealing cover 2.

[0021] Working principle: the bottom of the drainage tube body 4 is connected to the negative pressure ball 1, and the drainage tube body 4 and the negative pressure ball 1 are prevented from bending by the anti-bending device body 5. The anti-bending device body 5 mainly includes two parts: a limit spring 51 and a fixed cylinder 53; the fixed cylinder 53 prevents the root of the drainage tube body 4 from bending, and the limit spring 51 prevents the position above the root of the drainage tube body 4 from bending, so as to prevent the connection between the drainage tube body 4 and the negative pressure ball 1 from bending when the patient gets up and turns over. The drainage tube body 4 can remain unobstructed when the patient moves, so as to perform effective drainage; at the same time, it is avoided that when the drainage tube body 4 is folded, it is impossible to dynamically observe the patient's drainage, which hinders the doctor's judgment and diagnosis.

[0022] As a preferred implementation, the limit spring 51 is wrapped around the outside of the drainage tube body 4, and the cross-section of the limit spring 51 and the drainage tube body 4 is a concentric circle structure.

[0024] The limit spring 51 is a soft spring with recoverable elasticity. The limit spring 51 is wrapped around the outside of the drainage tube body 4 and can provide resistance protection for the drainage tube body 4 when it is subjected to force, thereby preventing the drainage tube body 4 from bending or blocking when it is subjected to force.

[0025] As a preferred embodiment, the cross-sections of the mounting plate 52 , the fixed tube 53 and the limiting plate 55 are arranged in an “I” shape, and an inner lining 54 is fixedly arranged on the inner wall surface of the fixed tube 53 , while the fixed tube 53 is wrapped around the bottom of the drainage tube body 4 by the inner lining 54 .

[0026] like Figure 1-3 As shown: the fixing tube 53 is a plastic tube, which is wrapped around the root of the drainage tube body 4 and can prevent the root of the drainage tube body 4 from bending.

[0027] As a preferred embodiment, the bottom of the limiting plate 55 is fixedly connected to the sealing plug 56, and the sealing plug 56 is an original tubular structure made of rubber material. At the same time, the sealing plug 56 is interference fit with the installation port 3, and the sealing plug 56 is inserted into the inside of the installation port 3.

[0028] The outer side of the limiting spring 51 is evenly covered with a layer of transparent dressing 511 , and the length of the limiting spring 51 is greater than the length of the fixing tube 53 .

[0029] In order to prevent the limit spring 51 from causing pressure marks on the patient's skin when the patient is resting in bed, a layer of transparent dressing 511 is wrapped on the outer surface of the limit spring 51, which can not only reduce the pressure marks on the skin, but also allow the drainage fluid at the end of the drainage tube to be observed.
