Description

Sleeve drainage device

Technical Field

The utility model relates to the field of medical instruments, in particular to a sleeve drainage device.

Background

The formation of the fistula is a common complication after the alimentary canal operation, the formation of the alimentary canal fistula is easy to be accompanied with the occurrence of infection, once the death rate is extremely high, the hospitalization time of a patient is prolonged, the economic burden is increased, and a series of subsequent complications seriously endangering the life cause great influence on the life health of the patient and the family economy. However, fistula formation is unpredictable and is often closely related to uncontrollable factors such as the constitution of the patient, local blood supply and the surrounding environment of the operation area.

The traditional drainage tube is generally made of silicon rubber or polyurethane and the like, one end of the traditional drainage tube is inserted into a wound surface which can generate fistula, the other end of the traditional drainage tube is connected with an extracorporeal device, and secretion, blood and pus in tissues or lacuna are drained outwards through negative pressure, gravity and the like. For some surgeries where contamination exists or may exist, such as gastrointestinal tract surgery, placing the drainage tube in advance can reduce the probability of postoperative inflammation and promote recovery of the patient.

However, in clinical practice, the following problems exist when using the traditional drainage tube for drainage: 1. drainage tubes are usually inserted in advance to prevent the formation of fistulas or abscesses, but for some patients, the insertion of drainage tubes in advance may cause side-effects of the treatment. 2. The drainage tube is inconvenient to replace: because the negative pressure device is connected to the outside, the suction force existing on the drainage tube placing end can cause the adsorption of tissues or the blockage of the drainage tube due to the viscosity of pus or blood stasis, and the re-placing of the drainage tube not only increases the treatment pain of a patient, but also increases the risk of secondary infection. 3. When drainage liquid is too viscous, drainage is usually performed clinically in a flushing mode, namely a flushing pipe of the inner sleeve is arranged in the drainage pipe, and the flushing pipe is flush with the drainage pipe. The flushing pipe is connected with the infusion bottle, and the drainage pipe is connected with the negative pressure device, thereby achieving the double effects of flushing and drainage. However, since the tip of the irrigation tube is flush with the drainage tube, the irrigation range is usually not uniform for a fistula with a large or narrow partial cavity, and it is difficult to sufficiently flush and suck pus at the far end to achieve the expected effect.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, provides a casing drainage device and solves the problems that the traditional drainage tube needs to be placed in advance, is easy to block, is difficult to replace and has poor flushing effect.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the sleeve drainage device comprises an outer sleeve, a drainage tube and a flushing tube, wherein the drainage tube and the flushing tube are arranged in the outer sleeve; one end of the outer sleeve tube extending into the body cavity of the human body is provided with a plurality of notches; one end of the drainage tube is used for connecting the negative pressure device, the other end of the drainage tube extends into the body cavity of the human body, and a plurality of gaps are arranged at one end of the drainage tube extending into the body cavity of the human body; one end of the flushing pipe is connected with the normal saline, the other end of the flushing pipe extends into the human body cavity, and one end of the flushing pipe extending into the human body cavity is provided with a plurality of notches.

The pipe diameter of outer tube is 8 ~ 12 mm.

The pipe diameters of the drainage pipe and the flushing pipe are 2.5-3.5 mm

The notch of the outer sleeve is circular, and the diameter of the notch is 8-9 mm.

The gaps of the outer sleeve are evenly arranged on the outer sleeve in a staggered mode, and the length of the whole gap arrangement area is 8-12 cm.

The shape of the notch of the drainage tube is circular, and the diameter of the notch is 1-2 mm.

The gaps of the drainage tubes are uniformly distributed in a staggered mode, and the length of the whole gap arrangement area is 12-14 cm.

The shape of the gap of the flushing pipe is circular, and the diameter of the gap is 1-2 mm.

The gaps of the flushing pipes are uniformly arranged in a staggered mode, and the length of the whole gap arrangement area is 4-6 cm.

Compared with the prior art, the technical scheme of the utility model has the following beneficial effects:

1. the built-in drainage tube is overlapped with the notch of the outer sleeve to form a columnar negative pressure suction area, and compared with a double-hole one-opening suction area of the existing drainage tube, the drainage tube has the advantages that the suction area for drainage is larger and more uniform.

2. When the drainage tube is blocked, the drainage tube is only required to be taken out, and is washed smoothly or directly replaced without replacing the outer sleeve, so that the operation is simple, and the pain and infection chances of a patient are reduced.

3. The part of the flushing pipe extending out of the external pipe is longer than the drainage pipe, and the length proportion is reasonable, so that the water flow of the flushing pipe and the suction airflow of the drainage pipe form vortex in the fistula cavity, and the irrigation and drainage are facilitated to be fully carried out.

4. When a fistula cavity with a narrow and wide cavity gap is treated, the drainage tube and the flushing tube exposed out of the outer sleeve can be properly extended, the imaging examination shows that when the fistula cavity is large, the ports of the drainage tube and the flushing tube can extend to different directions due to the fact that the ports of the drainage tube and the flushing tube contact with the fistula wall in the extending process, the outflow port and the drainage port of the extending part of the double tube can be staggered mutually, a multi-directional and full-coverage flushing-drainage area is formed in the pus cavity, and the large fistula cavity can be fully drained.

5. Because the external drainage tube generates certain attraction to surrounding tissues, the fistula wall tissues are in a state of continuously tending to be attached due to the attraction under the condition of full flushing, the filling of granulation tissues and fibrous tissues in the fistula is promoted, and the healing process is promoted. Under the trend, the outer sleeve is gradually pulled out slowly, and the hospitalization time of the patient is greatly shortened along with the continuous repair and healing of the fistula tissue in the process.

6. The utility model has simple manufacture and convenient placement, is mainly used for treating patients with fistula, does not need to be placed in advance to prevent the occurrence of the fistula, and effectively reduces the side injury of medical treatment.
