Abstract
The invention relates to medical check valves, in particular to a medical four-way valve mainly used for autologous fat transplant. The medical four-way check valve uses a four-way body and a check valve unit to form a through cavity and one-way flow, provides a one-way flow condition for serving as an intermediate carrier in fat transplant and achieves the purposes of suction and injection by being connected to other ancillary items, such as a syringe, a fat storage can and a liposuction needle. The medical four-way check valve can simplify a needle cylinder replacement mode of tumescent liquid injection, liposuction and fat injection in autologous fat transplant, facilitates continuous completion of the transplant and is easy to operate, capable of shortening transplant time, safe and practical.
Description
Technical field
A kind of Medical check valve, particularly a kind of medical four-way check valve.
Background technology
In clinical autologous fat transplantation operation, doctor needs conversion to use a lot of syringes and relevant fat suction equipment to complete Tumescent fluid injection, fatty sucking-off and fat transplantation, frequently change syringe cylinder due to the meeting of volume needs when playing Tumescent fluid and greasing and meet requirements of operation, and when extracting fat, also need replacing syringe to store.Owing to using object more, displacement is frequent, causes operating time prolongation or action to complete discontinuous.And the one-way conduction principle of check valve is used in invention, one-way flow passage is in use provided, play Large Copacity and concentrate the effect of injecting or discharging, can reach in operation process beat Tumescent fluid, liposuction, greasing complete continuously completely under same environment, need not be too much by other apparatuses, reach quick, safe and effective object, be all Gospel concerning surgical doctor and patient.
Summary of the invention
The object of the invention is to make operative doctor easy to operate, quick in autologous fat transplantation process, reduce the time of operation, avoid adipose cell cross-contamination, improve the safety of operation.
The object of the invention is to realize in the following manner, comprise four entire bodies (1), check valve (2), unidirectional valve pocket (3), syringe needle guide pillar (4), interior tooth union joint (5), outer tooth union joint (6), plug (7); Four entire bodies (1) inside is for intersecting intercommunication pipeline, check valve (2) is arranged in four entire bodies (1) by unidirectional valve pocket (3), in interior tooth union joint (5), syringe needle guide pillar (4) is installed, interior tooth union joint (5), outer tooth union joint (6) are arranged in four entire bodies (1), and plug (7) is arranged on outer tooth union joint (6).
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In order to understand content of the present invention further, Characteristic, be further detailed as follows with reference to the accompanying drawings:
Fig. 1 medical four-way check valve comprises four entire bodies (1), check valve (2), unidirectional valve pocket (3), syringe needle guide pillar (4), interior tooth union joint (5), outer tooth union joint (6), plug (7); Described unidirectional valve pocket (3), syringe needle guide pillar (4), interior tooth union joint (5), outer tooth union joint (6), plug (7) all adopt rustless steel to make, and repeatedly can sterilize, avoid the wasting of resources; Check valve (2) makes for silica gel, can repeated disinfection use; Check valve (2) for irreversible to hindering back design; Four entire bodies (1) are four direction passages, inner for intersecting intercommunication pipeline; Check valve (2) is arranged in four entire bodies (1) by unidirectional valve pocket (3), in interior tooth union joint (5), syringe needle guide pillar (4) is installed, interior tooth union joint (5), outer tooth union joint (6) are arranged in four entire bodies (1), and plug (7) is arranged on outer tooth union joint (6).
Claims (2)
1. a medical four-way check valve, comprise four entire bodies (1), check valve (2), unidirectional valve pocket (3), syringe needle guide pillar (4), interior tooth union joint (5), outer tooth union joint (6), plug (7), it is characterized in that: four entire bodies (1) inside is for intersecting intercommunication pipeline, check valve (2) is arranged in four entire bodies (1) by unidirectional valve pocket (3), in interior tooth union joint (5), syringe needle guide pillar (4) is installed, interior tooth union joint (5), outer tooth union joint (6) are arranged in four entire bodies (1), and plug (7) is arranged on outer tooth union joint (6).
