Abstract
The utility model relates to a closed type induced abortion instrument which mainly comprises an inducing elbow (1), an inducing port (2), an inducing pipe (3), a negative pressure controller (4), a sample collecting bottle (5), a sample inducing port (6), a one-way check valve (7), a negative pressure connecting port (8), a negative pressure connecting pipe (9) and a negative pressure power resource connector (10). During a negative pressure inducing process of induced abortion by using the closed type induced abortion instrument, the route for an induced human tissue falling into the sample collecting bottle is greatly shortened, the time for a doctor observing an induced sample is greatly shortened, the empty inducing and leaking inducing are extremely reduced and the operation time is shortened. Meanwhile, due to the full-closed inducing channel design, the countercurrent pollution and the exogenous pollution are prevented.
Description
Affiliated technical field
This utility model relates to a kind of artificial abortion's apparatus of closed, belongs to disposable medical apparatus and instruments category.
Background technology
Along with the enforcement of China's family planning policy, artificial abortion operation has become a kind of main means that stop unexpected gestation, is effective means to save the situation behind the contraceptive failure.According to statistics, ten thousand artificial abortion of the annual nearly 2500-5500 in the whole world.Since the later stage eighties in last century, the annual people's fluxion of China continues about 1,000 ten thousand always.The improper complication such as infection, intrauterine adhesion that cause of artificial abortion, and the defective of the artificial abortion's apparatus that generally uses now itself is one of reason of bringing out above-mentioned complication.
Vacuum suction artificial abortion art is a kind of method of easy, comparatively safe termination of pregnancy; Because the controllability of artificial abortion's suction catheter is relatively poor; Stroke between suction catheter and the negative pressure power source is long; Occur suction easily, leak to inhale, the suction official is not complete, the perforation of uterus, amniotic embolism etc., adverse consequencess such as intrauterine adhesion, infection, menoxenia and secondary infertility can appear in postoperative.The improvement of artificial abortion's apparatus and technical raising are with the raising of the healthy reproduction level that directly promotes the women.
Summary of the invention
For overcome that artificial abortion's apparatus clinically exists deficiency, the present invention proposes a kind of manufacturing process artificial abortion's apparatus simple, with low cost, a kind of closed safely and effectively.
The present invention is mainly by attracting elbow, attracting mouth, suction catheter, negative pressure controller, sample collection bottle, sample inhalation port, unidirectional non-return valve, negative pressure connector, negative pressure connection tube, negative pressure power source union joint to form.
1, the attraction elbow is communicated with suction catheter or has a style of one's own, and attracts elbow to be provided with and attracts mouth.Attract elbow and suction catheter can adopt PE or PP material to process, certain rigidity and anti-negative pressure deformability should be arranged.
Suction catheter can be single lumen catheter, also can be double lumen tube, and length is generally about 24cm.Preferably adopt double lumen tube; One chamber is used for sucking-off embryonal tissue; Another chamber is for regulating the inlet channel of negative pressure in the uterine cavity; It is smooth or block phenomenon because of the raise attraction pipeline caused of negative pressure in the uterine cavity in vacuum suction to solve single chamber artificial abortion's suction catheter effectively, reduces the number of times that artificial abortion manages the turnover uterine cavity.
2, the sample collection bottle is provided with sample inhalation port and negative pressure connector, and sample inhalation port, negative pressure connector are communicated with the sample collection bottle.
3, the front end of negative pressure controller is communicated with suction catheter or has a style of one's own, and the rear end is communicated with the sample inhalation port.
4, be provided with unidirectional non-return valve in the path between attraction elbow and the sample collection bottle, unidirectional non-return valve can attract any position in the path between mouth and the sample collection bottle.
5, the sample collection bottle can be communicated with the negative pressure power source through negative pressure connector, negative pressure connection tube, negative pressure power source union joint successively, and any position between sample collection bottle and the negative pressure power source union joint in the path also can be provided with unidirectional non-return valve.
6, unidirectional non-return valve can adopt good springiness, material that reproducibility is strong to process, and is better with the unidirectional non-return valve of Duckbill type that silica gel is processed.When negative pressure controller was opened negative pressure, unidirectional non-return valve can be opened the path of suction catheter and sample collection bottle, and the human tissue sample of being convenient to attract falls in the sample collection bottle smoothly; When negative pressure controller is closed negative pressure, unidirectional non-return valve auto-closing, blocking-up sample collection bottle and extraneous path prevent that the human tissue sample adverse current that sucks in artificial abortion's process from going out the sample collection bottle or causing exogenous pollution.
7, the sample collection bottle is provided with the volume scale, and bottle is generally transparent medical macromolecular materials and processes.
Advantage of the present invention is:
1, attract the mouth and the spacing of sample collection bottle to shorten greatly; When artificial abortion's vacuum suction, can shorten the stroke that the tissue that drains falls into the sample collection bottle greatly, shorten the time that the doctor observes the drain sample greatly; At utmost reduce suction, leak and inhale, shorten operating time.
2, the attraction via design of total enclosing prevents adverse current pollution and exogenous pollution.
3, disposable use, the cross infection risk of avoiding sterilizing and thoroughly not causing.
4, adopt the sample collection bottle to gather and the sealing sample, be convenient to check have or not fine hair and embryonal tissue in the aspirate, observe size whether with pregnant Zhou Xiangfu, also be convenient to tissue substance transmission and censorship simultaneously.
