Description
Technical field
The utility model is related to medical instruments fields, and in particular to a kind of negative pressure catheter pressure reducing valve.
Background technology
After patient's operation now, in order to avoid wound inflammation and cross-infection, negative pressure continuous drainage need to be carried out to the surface of a wound, born
It needs to use negative pressure catheter pressure reducing valve when pressing continuous drainage.Negative pressure continuous drainage enough accelerates the blood circulation of wound site, shows
It writes and new vessels is promoted to enter the surface of a wound, stimulate the growth of granulation tissue, fully drain, mitigate oedema, reduce pollution, inhibit bacteria
Growth can directly accelerate wound healing or repair for operation to create conditions.During negative pressure treatment, negative pressure can be by the exudation of the surface of a wound
Object timely attracts, and can change a medicine everyday at least three, with wound healing is fast, infection rate is low, more change dressings number
Less, Antibiogics usage is few, reduces the features such as medical expenses, energy accelerating wound healing, reduces the expenditure of medical expenses.
However existing negative pressure catheter is unreasonable with structure of relief pressure valve design, influences therapeutic effect；And complicated production
Cost is excessively high.
The content of the invention
Problem to be solved in the utility model is to overcome the shortcomings of negative pressure catheter pressure reducing valve in the prior art, provides one
The negative pressure catheter pressure reducing valve of kind structure design advantages of simple.
To solve the above-mentioned problems, a kind of negative pressure catheter pressure reducing valve of the utility model, the pressure reducing valve include decompression
Cavity and the adjuster on decompression cavity, the decompression cavity include decompression shell cavity and in decompression shell cavities
Section is the flexible cavity of several fonts, arranged on the liquid inlet of flexible cavity one end and the liquid outlet of the other end, the liquid
Entrance and liquid outlet are adapted with drainage tube, and the adjuster includes the rotational shell that section is convex shape；Outside the rotation
Shell adjusts relative position relation with decompression shell cavity by the first connection screw thread, and rotational shell inside upper surface is connected by elasticity
Fitting is connected with briquetting；The briquetting moves reciprocatingly with rotational shell compared with decompression shell cavity；The briquetting and elasticity
The epicoele face paste of cavity, which is closed, to be set.
As further improvement of the utility model, the decompression shell cavity is rounded cuboid.
As further improvement of the utility model, decompression shell cavity corresponds to liquid inlet and liquid outlet is equipped with and opens
Mouthful.
As further improvement of the utility model, the rotational shell is equipped with offset protrusion.
As further improvement of the utility model, the height ratio of the adjuster and decompression cavity is 2.4-4.2:1.5-
2.5。
As further improvement of the utility model, first connection screw thread is equipped with limit protrusion.
As further improvement of the utility model, the liquid inlet and liquid outlet are connected through a screw thread with drainage tube
Or Rule pipe connection.
The utility model has the following advantages compared with prior art.
The negative pressure catheter of the utility model designs advantages of simple with structure of relief pressure valve, and decompression or voltage regulation result are good, Neng Gouman
Sufficient requirement.It is avoided that negative pressure drainage is excessive to the suction of wound, causes the feeling of pain of wound, patient occurs uncomfortable；It is existing
The complex structural designs of some pressure reducing valves are unsuitable for industrialized production and promote the use of；The pressure reducing valve of the utility model subtracts
Cavity and the adjuster on decompression cavity are pressed, decompression cavity includes decompression shell cavity and cut in decompression shell cavity
Face is the flexible cavity of several fonts；Adjuster includes the rotational shell that section is convex shape；Briquetting and upper table on the inside of rotational shell
Face is adapted；Rotational shell adjusts relative position relation, rotational shell inside with decompression shell cavity by the first connection screw thread
Upper surface is connected with briquetting by flexible connector；The epicoele face paste of briquetting and flexible cavity, which is closed, to be set；The utility model passes through
Opposite distance is adjusted by screw thread rotation between rotational shell and decompression shell cavity, briquetting is with rotational shell compared with decompression
Shell cavity moves reciprocatingly with the variation of distance, and briquetting is changing the pressure that flexible cavity is given, and flexible cavity
Volume is also changing, and the pressure that the in vivo fluid of elastic cavity receives therewith is also different, so as to have the function that adjust pressure,
It is mostly used for depressurizing.
Since decompression shell cavity is rounded cuboid, decompression shell cavity corresponds to liquid inlet and liquid outlet is equipped with and opens
Mouthful；Rotational shell is equipped with offset protrusion, and offset protrusion can be identified for that rotational shell moves reciprocatingly compared with decompression shell cavity
With the variation of distance, indicative function is given；The height ratio of adjuster and decompression cavity is 2.4-4.2:1.5-2.5 the ratio
Lower structure is stablized, and the first connection screw thread is equipped with the pressure that limit protrusion is capable of /V adjustment.
