Abstract
The utility model relates to abortion surgical equipment for family planning in the medical industry, in particular to a two-way micro-pump uterine cavity drainage instrument which mainly comprises a disposable two-way surgical micro-tube and a constant peristaltic pump, wherein the disposable two-way surgical micro-tube is connected with the constant peristaltic pump through a silicone tube. The suction port of the disposable two-way surgical micro-tube is connected to the negative pressure port of the peristaltic pump and an air inlet port is connected to the positive pressure port of the peristaltic pump. The peristaltic pump provides the air inlet port with constant pressure when the negative pressure suction port of the peristaltic pump works. Thereby, the negative pressure of a uterine cavity can be reduced, the goal of balancing pressure in the uterine cavity is reached, the pain of a patient is eliminated, the goal of painless surgery is really realized and the risks in surgeries can be reduced.
Description
Affiliated technical field
This utility model relates to a kind of abortion's equipment of medical industry family planning, especially can solve the suction pump of the risk of patient's painful and operation in the operation.
Background technology
Traditional abortion connects by suction pump to attract sebific duct, connects metal dilatation and curettage device again and undergos surgery, and following deficiency is arranged in the abortion:
(1) the dilatation and curettage device is thick excessively
Traditional dilatation and curettage device is based on the metal stainless steel tube, and diameter is 6-10mm, because the dilatation and curettage device is thick, hard, must expands the palace and enter the uterine cavity use.Weak point shows as:
1, must expand the palace and enter uterine cavity;
2, must repeated disinfection use, increase the probability of cross infection;
3, opening is big, negative pressure is big, easily causes the comprehensive complication of artificial abortion, as big, hemorrhage many, endometrium perforation of wound surface etc., easily causes gynaecopathias such as infertility, pelvic inflammatory disease, cervicitis.
(2) vacuum extractor
The holding property of negative pressure that traditional vacuum extractor produces is big, and the uterine contraction that causes in the process of the artificial abortion clearing heat in the pericardium is excessive, the endometrium extrusion friction damages, post-operative recovery is slow.These deficiencies mainly show as simple vacuum suction, and internal pressure of uterine cavity power is big, thereby patient's pain unbearably.
(3) microtubule artificial abortion art
Microtubule artificial abortion is as the term suggests be to have realized little footpath on " pipe ".Microtubule can directly be gone into cervix uteri and be arrived uterine cavity, though solved the problem that expands the palace pain, the uterine contraction pain problem that negative pressure causes still exists.
Summary of the invention
In order to overcome the risk that exists in pain that existing people's flow device brings and the operation, this utility model provides a kind of two-way Micropump uterine cavity drain instrument, and this drain instrument can not only be eliminated patient's pain, and can reduce the risk in performing the operation.
The technical scheme that its technical problem that solves this utility model adopts is: two-way Micropump uterine cavity drain instrument is set up admission pressure peristaltic pump and air inlet microtubule, has reduced the uterine cavity negative pressure, reaches real painless purpose; And use the arbitrarily microtubule of bending, need not expand the palace, directly absorb pregnant capsule, operating time is short, attraction is light, go out insufficiency of blood, avoided the large tracts of land clearing heat in the pericardium, endometrial damage is little, and then the incidence rate of complication is also little, the risk of the perforation of uterus is almost nil, has reduced the risk in the operation greatly.
Technical scheme
A kind of two-way Micropump uterine cavity drain instrument is made up of disposal bidirectional operation microtubule and bi-directional constant peristaltic pump, it is characterized in that: disposal bidirectional operation microtubule has the passage of attraction and inlet channel in the same pipe.The bi-directional constant peristaltic pump has vacuum suction port and positive port, provides negative pressure simultaneously, and positive air pressure also is provided.
In this utility model, the attraction passage of disposal bidirectional operation microtubule is connected to the negative pressure end of bi-directional constant peristaltic pump by silica gel tube, attracts intrauterine pregnant capsule, also siphons away intrauterine air when drawing pregnant capsule.Simultaneously, the inlet channel of disposal bidirectional operation microtubule, be connected to the positive pressure side of bi-directional constant peristaltic pump by silica gel tube, under lever operated device control air pressure, carry air to the uterus, thereby reach uterine cavity inner equilibrium pressure, realize constant negative pressure and constant malleation, deduction and exemption are because the pain that uterine contraction causes.
Description of drawings
Fig. 1 is a disposal bidirectional operation microtubule.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the bi-directional constant peristaltic pump.
The specific embodiment
In the embodiment shown in fig. 1, microtubule attracts mouthful (1), a microtubule (2), microtubule to attract connector (3) intercommunication, is connected on the silica gel tube (7), under the drive by peristaltic pump pump head (8), produce negative pressure in the silica gel tube (7), thereby drain is attracted in the drainage bottle in (9).
Air is from filtering gas stone (12) under the effect of peristaltic pump pump head (11) simultaneously, send into uterine cavity by silica gel tube (10), microtubule air inlet connector (6), lever operated device (13), microtubule (5), microtubule air inlet (4), thereby reach the internal pressure of uterine cavity dynamic balance.
Claims (3)
1. two-way Micropump uterine cavity drain instrument, disposal bidirectional operation microtubule, be connected to constant two peristaltic pump uterine cavity drain instrument that drives by silica gel tube, it is characterized in that: peristaltic pump uterine cavity drain instrument has vacuum suction port and positive port, when the work of peristaltic pump vacuum suction end, the malleation peristaltic pump of uterine cavity drain instrument also provides air pressure.
2. two-way Micropump uterine cavity drain instrument according to claim 1 is characterized in that: disposal bidirectional operation microtubule has the passage of attraction and inlet channel in the same pipe.
3. two-way Micropump uterine cavity drain instrument according to claim 1 is characterized in that: the admission pressure of lever operated device control disposal bidirectional operation microtubule.
