Abstract

The utility model relates to a hand controlled negative pressure suction device, which is composed of a suction pipe, a hand controlled piston and a joint; a transverse positioning pin is arranged on the hand controlled piston which is adjacent to a cylinder on the front end; the positioning pin can be telescopic under the action of a spring on the bottom of the pin; a fixed ejector pin is arranged on an outer circle of a tapered inserting pipe on the front end of the suction pipe corresponding to a gap slot on the joint; the slot is provided with transverse bend can be used for realizing the axial positioning for the inserted ejector pin. The utility model has the advantages of simple structure, easy use, high safety and multiple use; the utility model can be applied to plastic surgery such as fat suction, fat fill, etc. The utility model does not utilizes electricity and has low cost, the utility model is especially suitable for basal medical units and hospitals of remote areas and mountain areas.

Description

Manual vacuum extractor
This utility model relates to medical instruments, and concrete is a kind of manual vacuum extractor.
In medical clinical experiment, a lot of treatments, operation all will be used vacuum extractor, and in the prior art, vacuum extractor generally uses electronic negative pressure pump to produce suction, its structure more complicated, and the cost height, no electric field can not use.
Of the present utility modelly provide a kind of manual vacuum extractor, simple in structure, cost is low, processing ease, and the suitability is wide.
The purpose of this utility model is achieved in that a kind of manual vacuum extractor, form by suction pipe, manual piston and joint, the manual piston suction pipe of packing into, this piston crown becomes gastight with the suction pipe endoporus and is slidingly matched, the front end of suction pipe has tapered cannula to become to be sealed and matched with connector receptacle, suction spindle is housed on the joint, it is characterized in that:
A. manual piston is provided with horizontal alignment pin near the cylinder of front end, and this alignment pin is subjected to the effect of pin bottom spring and extended on the face of cylinder and be retracted to below the face of cylinder;
B. have the gap slot on fixed protruding pin and the joint corresponding on the tapered cannula cylindrical of suction pipe front end, this slot has horizontal bending that the protruding pin that inserts is realized axial location.
The purpose of this utility model can also realize by following measure:
Located lateral pin on the described manual piston cylinder is by upper and lower protruding pin, spring and sleeve pipe are formed, this sleeve pipe is an end opening, one end has the structure that small sircle hole was arranged at the end and the end, described upper and lower protruding pin is the ladder cylindrical shape, the following protruding pin microcephaly sleeve pipe of packing into downwards, its microcephaly passes in the sleeve bottom aperture, between upper and lower protruding pin, spring is housed, the last protruding pin microcephaly sleeve pipe of upwards packing into, this sleeve pipe is fixedly packed in the macropore of the ladder circular hole on the manual piston cylinder, and the microcephaly of last protruding pin stretches out in the aperture of cylinder ladder circular hole.
Described suction pipe and manual piston are made with plastic plastics, and manual piston crown is equipped with rubber seal, and the joint that the suction pipe end connects is made with rustless steel.
This utility model has following actively useful effect;
1. simple in structure, easy to use, safe.
2. multipurpose: can be applicable to plastic surgery such as liposuction, fat is filled, the closed drainage in thoracic cavity, abdominal cavity, expectorant rescue etc. is inhaled in gynecological's artificial abortion;
3. not electricity consumption is specially adapted to medical institutions and each hospital of remote districts, mountain area, basic unit;
4. cost is low, is easy to promote.
Now in conjunction with the accompanying drawings:
Fig. 1 is a structural representation of the present utility model, is the state in the vacuum suction use;
The same Fig. 1 of Fig. 2 shows the piston positioning states;
Fig. 3 is an assembly decomposing schematic representation of the present utility model.
Manual vacuum extractor of the present utility model, form by suction pipe 1, manual piston 2 and joint 3, the manual piston suction pipe of packing into, this piston crown becomes gastight with the suction pipe endoporus and is slidingly matched, the front end of suction pipe has tapered cannula to become to be sealed and matched with connector receptacle, suction spindle 4 is housed on the joint, and its structure please refer to Fig. 1 Fig. 2 Fig. 3.
A. manual piston is provided with horizontal alignment pin near the cylinder of front end, and this alignment pin is subjected to the effect of pin bottom spring 501 and extended on the face of cylinder and be retracted to below the face of cylinder;
B. have fixed protruding pin 102 corresponding with the gap slot 301 on the joint 3 on tapered cannula 101 cylindricals of suction pipe 1 front end, this slot has the protruding pin 102 of 302 pairs of insertions of horizontal bending to realize axial location, makes its not excessive and slippage of reason negative pressure.
In preferred embodiment, located lateral pin on the described manual piston cylinder is by last protruding pin 502 and following protruding pin 503, spring 501 and sleeve pipe 504 are formed, this sleeve pipe 504 is an end opening, one end has the structure that small sircle hole was arranged at the end and the end, the described protruding pin 502 of going up is the ladder cylindrical shape with following protruding pin 503, the following protruding pin 503 microcephalies sleeve pipe 504 of packing into downwards, its microcephaly passes in the sleeve bottom aperture, spring 501 is contained in, between the following protruding pin, the last protruding pin 502 microcephalies sleeve pipe 504 of upwards packing into, this sleeve pipe are fixedly packed in the macropore of the ladder circular hole 202 on the manual piston cylinder, and the microcephaly of last protruding pin 502 stretches out in the aperture of cylinder ladder circular hole 202.During use, upper and lower protruding pin 502,503 is pressed into sleeve pipe 504, just piston can be pushed suction pipe with finger.When producing negative pressure when outside twitch piston in suction pipe, alignment pin one withdraws from suction pipe, and under spring action, upper and lower alignment pin ejects the location simultaneously from the cylinder two ends, piston is sucked suction pipe by negative pressure provide constraints.
During enforcement, described alignment pin also can replace with simple manual horizontal latch.
During enforcement, described suction pipe 1 and manual piston 2 usefulness plastic plastics are made, and manual piston crown is equipped with rubber seal 201, and the joint 3 usefulness rustless steels that suction pipe 1 end connects are made.
