Technical Field

The invention relates to the technical field of medical devices, in particular to a multifunctional dripping double-sleeve which is sterile and easy to replace and has small damage to tissues.

Background

At present, a dripping double cannula is a drainage device applied to abdominal surgery and is often used in the treatment process of diseases such as abdominal cavity infection, digestive fistula, severe pancreatitis and the like. Most of the traditional dripping double sleeves are manufactured by medical personnel in departments, the aseptic requirement cannot be ensured, the manufactured finished products have different quality, the suction tube is easy to block, and the inner part of the sleeve is not easy to clean; the irrigation tube is usually sewn on one side of the suction tube, so that the patient often suffers from severe pain when changing the tube and is not easy to distinguish whether to place the tube in the original position, and in addition, a large amount of air is sucked into the suction tube, which may cause secondary infection.

Therefore, a multifunctional drip double cannula which is sterile and easy to replace and has little damage to tissues is needed.

Disclosure of Invention

The invention provides a multifunctional dripping double-cannula with scales, sterility, easy replacement and little damage to tissues for solving the problems in the prior art, and the specific technical scheme is as follows:

the utility model provides an aseptic easy change is to small multi-functional double cannula that drips of tissue damage, includes inlet tube, sleeve pipe and attracts the pipe, the inlet tube includes inlet tube A and inlet tube B, and both are broken line's an organic whole structure, inlet tube A length direction is outside along sleeve pipe length direction rigid coupling in the inside pipe wall, and the sleeve pipe is located to inlet tube B, and the one end of inlet tube is the inlet tube opening, and the other end is equipped with the sealing cap of adaptation, attract the one end of pipe through attracting pipe thread structure threaded connection in sleeve pipe thread structure, attract being equipped with the brush around the lateral wall of pipe, through-hole A and through-hole B have been opened respectively to sheathed tube lateral wall and the lateral wall of attracting the pipe, the one side that the thread structure of attracting.

Furthermore, the sleeve, the suction tube and the water inlet tube are transparent structures, and the diameters of the sleeve, the suction tube and the water inlet tube are reduced in sequence.

Furthermore, the outer wall of the sleeve is provided with scales along the length direction.

Furthermore, the thread structure of the suction tube is an external thread, one end of the thread structure of the sleeve is an internal thread, and the internal thread and the external thread are connected in a rotating manner.

Furthermore, the diameter of the through hole A is the same as that of the through hole B.

Further, the air filtering membrane is made of a micro-porous filtering membrane material.

Furthermore, the tail end of the sleeve is of an arc-shaped closed structure.

By adopting the technical scheme, the method has the following beneficial effects:

the invention has simple integral structure and convenient use, records the depth of the tube through the scale, takes off the sealing cap to connect with the physiological saline, connects the suction tubes together through the thread structure at the tail end of the sleeve, connects the suction tubes with the negative pressure device, slowly drops the physiological saline from the head end of the sleeve, washes the tissues around the drainage area, enters the sleeve along the through hole A of the sleeve, and drains out of the body through the suction tube; in order to balance the pressure in the sleeve, outside air enters the sleeve through the air filtering membrane, so that secondary pollution of bacteria in the air is avoided; if the drainage is not smooth, the suction tube can be slightly rotated, the hair brush at the head of the suction tube can clean the cellulose, the necrotic tissues attached to the wall and the like in the sleeve, and the blockage in the sleeve can be taken out together with the pulling of the suction tube out of the body, and then a new suction tube is replaced; if the drainage is still not smooth, the sleeve and the suction tube can be integrally replaced, and the tail end of the sleeve is of a blunt closed structure, so that the visceral organs in the abdominal cavity can be prevented from being damaged during tube replacement, and meanwhile, the suction tube is prevented from sucking the abdominal tissues into the sleeve; the sleeve and the flushing pipe for water inlet are of an integrated structure, and the flushing pipe runs inside the sleeve, so that the pain of a patient is greatly relieved when the sleeve is replaced; in addition, the scales on the sleeve can help to judge the tube entering depth and determine whether the tube is placed in the original position.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example 1: an aseptic easily change two sleeve pipes that drip to the little multi-functional of tissue damage as shown in fig. 1 to fig. 3, including inlet tube, sleeve pipe 12 and attract pipe 13, the inlet tube includes inlet tube A1 and inlet tube B6, and both are the integrative structure of broken line, inlet tube A1 length direction is along sleeve pipe 12 length direction rigid coupling in sleeve pipe 12 inner wall, and inlet tube B6 locates the sleeve pipe outside, and the one end of inlet tube is inlet tube opening 2, and the other end is equipped with the sealing cap 5 of adaptation, attract 13 one end of pipe through attracting 11 threaded connection of pipe structure 7, attract being equipped with brush 9 around the lateral wall of pipe 13, through-hole A3 and through-hole B8 have been opened respectively to the lateral wall of sleeve pipe 12 and the lateral wall that attracts pipe 13, it is equipped with filtration membrane 10 to attract one side that pipe threaded structure 11 is close to brush 9.
