Abstract

The utility model relates to a drug-feeding uterine neck expansion tube, comprising a tube body with a plurality of millipores, a passage is arranged in a cavity of the tube body, one end of the passage is connected with an air-pocket film, the other end is connected with a normally closed one-way valve, the rear end of the tube body is connected with a chassis with a needle, the head portion of the tube body has a certain taper. The utility model has the advantages of safety, hygiene, low cost, easy operation, and is fit for wide application.

Description

But medicine infusion type cervical dilatation catheter

(1) technical field

This utility model relates to a kind of medical apparatus and instruments, but particularly a kind of medicine infusion type cervical dilatation catheter.

(2) background technology

In gynecological diagnosis and therapeutic process, in operations such as artificial abortion, diagnostic curettage, need carry out cervical dilatation to patient, owing in the cervix uteri many teleneurons are arranged, when implementing cervical dilatation, when being subjected to tractive, can cause neural reflex in various degree, be easy to generate rest pain, cervix uteri is nervous to be shunk, even produce " artificial abortion syndromes " such as hypertension, dizzinesses, at present, general clinically anesthesia earlier afterwards expanded, cumbersome, and can bring certain misery to patient.

(3) summary of the invention

This utility model is in order to solve the defective that above-mentioned prior art exists, but a kind of safety and sanitation, expense is low, efficient is high, easy to operate medicine infusion type cervical dilatation catheter are provided.

This utility model is realized by following measure: but a kind of medicine infusion type cervical dilatation catheter, comprise the body that has a plurality of micropores, described tube cavity has a passage, passage one end is connected with air bag and film, the other end is connected with normally closed check valve, the body end is connected with the base of band syringe needle, and the head of described body has certain taper.

Micropore on the described body is opened is not having the part of air bag and film.

The beneficial effects of the utility model: safety and sanitation, expense is low, efficient is high, easy to operate, suitable applying.

(4) description of drawings

Below in conjunction with drawings and Examples this utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

1 micropore among the figure, the state of 2 air bag and film bulgings, 3 air bag and films (air bag and film is the state of bulging not), 4 passages, 5 pipe joints, 6 connect sebific duct, 7 normally closed check valves, 8 normally closed check valve inlets, 9 bodys, 10 catheters, the base of 11 band syringe needles, 12 springs, 13 normally closed check valve outlets.

(5) specific embodiment

But a kind of medicine infusion type cervical dilatation catheter as shown in Figure 1, comprise the body 9 that has a plurality of micropores 1, described body 9 inner chambers have a passage 4, passage 4 one ends are connected with air bag and film 3, the other end is connected with normally closed check valve 7, body 9 ends are connected with the base 11 of band syringe needle, and the head of described body 9 has certain taper.

Passage 4 in the body 9 links to each other by patching metallic pipe coupling 5 with catheter 10 other ends.

Described normally closed check valve 7 is made of cylindrical shell, spring 12 and valve body.

The base 11 of described body 9, catheter 10 and band syringe needle constitutes an integral body, so that medicinal liquid enters body 9 smoothly; Body 9 does not have the micropore 1 of 100 diameter 0.3mm getting by laser-beam drilling machine on the sidewall of part of air bag and film 3.

But but the using method of medicine infusion type cervical dilatation catheter be will sterilization the medicine infusion type cervical dilatation catheter be that air bag and film 3 inserts from the cervix uteri mouth when being close to body 9 and being tubule at contraction state, to receive on the needle tubing with the base 11 of syringe needle earlier, body 9 is inserted patient's cervical canal, pushing syringe, medicinal liquid under high pressure sprays by the micropore 1 of body 9, pass cervical mucus, blocking-up cervix uteri neural reflex, then to blister cavities filling air or water, the syringe nozzle that takes out metal needle puts in normal closed gate 8 places that enter the mouth, valve body is pushed up inwards, and the end that has breach on the valve body enters valve shell convex shoulder place, and normally closed check valve 7 is opened, passage 4 is communicated with to blister cavities from entering the mouth, can realize that to the blister cavities filling realize the expansion of blister cavities, cervical dilatation is finished.Take out syringe, valve body is automatically reset by the elastic force of spring 12 to close, and recovers " normally closed " state, and the air in the blister cavities or the pressure of water are maintained.

Claims

1. but medicine infusion type cervical dilatation catheter, it is characterized in that: comprise the body (9) that has a plurality of micropores (1), described body (9) inner chamber has a passage (4), passage (4) one ends are connected with air bag and film (3), the other end is connected with normally closed check valve (7), body (9) end is connected with the base of band syringe needle, and the head of described body (9) has certain taper.
