Description

Disposable multifunction cervical dilator

Technical field

This utility model relates to a kind of cervical dilator, is specifically related to disposable multifunction cervical dilator.

Background technology

Pregnant woman childbirth overall process is divided into three stagess of labor, wherein first stage of labor, is called the dilatation of cervix phase, and this is a more crucial process, because adult female's cervical canal is about as 3cm, tube chamber is fusiformis, and cervical orifice is tighter, in the time of childbirth, because anemia of pregnant woman's the reason such as body constitution and psychologic status can make first stage of labor elongated, the easy like this fetal anoxia that causes, makes neonatal immunity power low, or even makes mother and baby all be vulnerable to antibacterial infection.

May adopt under normal circumstances the method for medicine or mechanical expansion to carry out practise midwifery, comparatively advanced way is to adopt soft contact expansion now.Air sac type cervix dilatation device as disclosed in China Patent Publication No.: 202933377U, comparatively simple in this dilator structure, swelling gasbag is arranged on one end of gas tube, another pipe of gas tube connects inflatable interface, and be also connected with plug, and be full of swelling gasbag by air or normal saline, then on inflatable interface, clog gas tube with plug, and delivery tube is the outside that is enclosed within gas tube, and on inwall, there is rib between delivery tube and gas tube.

The disclosed cervical dilator of and for example China Patent Publication No.: 202620454U, structure and air sac type cervix dilatation device are similar, difference is in swelling gasbag for double-deck, mainly because when actual use, because often must clamping swelling gasbag with operating forceps, doctor sent into cervix uteri mouth, so double-deck being difficult for of just showing clips broken, and clogs gas tube with plug in the time that inflation completes.

Reality in use, can there is following problem in this kind of dilator, one is needing to use plug to swelling gasbag inflation or after squeezing into normal saline, the inconvenient situation that at every turn all there will be gas leakage or leakage of not saying, two are administered for cervix uteri place, and if uterus inwall is hemorrhage or inflammation has just been given less than medicine.

Summary of the invention

The purpose of this utility model is exactly few in order to solve existing cervix uteri soft contact expander function, inflation or saline injection technical problem not easily.

Disposable multifunction cervical dilator, comprise gas tube, drug feeding pipe and swelling gasbag, gas tube communicates with swelling gasbag, it is characterized in that: gas tube is wrapped in the periphery of drug feeding pipe, gas tube tube head extends from separating a backward side near the place of drug feeding pipe tube head, and a side breathing space of swelling gasbag terminates in the other end tube head district of drug feeding pipe; Described gas tube tube head is or/and drug feeding pipe tube head is provided with check valve, this check valve comprises overcoat and inner core, gas tube tube wall is sandwiched in inner core outside by overcoat, interior in-core has a horn-like cavity, in cavity, place a cork, cross underframe has been set up in the below of cavity, and cork periphery in the time of compression forms space connects inner core passage.

Drug feeding pipe Gai Duan tube head district is provided with medicine outlet hole.

At gas tube, just near the place of breathing space, the some places of drug feeding pipe tube wall extends to form insecticide-spraying hole laterally.

This utility model beneficial effect is as follows:

Compared with prior art, this utility model structure is more reasonable, install check valve inflation or note normal saline additional convenient, the situation that there will not be gas leakage or leak medicine, swelling gasbag one side breathing space terminates in the other end tube head district of drug feeding pipe, and medicine outlet hole is called in district at Gai Duan tube head, make dilator except expansion cervix, can also realize the function toward intrauterine administration.

Brief description of the drawings:

Fig. 1 is generalized section of the present utility model;

Fig. 2 is Fig. 1 partial enlarged drawing.

Detailed description of the invention:

Below in conjunction with accompanying drawing, this utility model is done to further detailed elaboration.

Consult Fig. 1, Fig. 2, disposable multifunction cervical dilator, comprise gas tube (1), drug feeding pipe (2) and swelling gasbag (3), gas tube (1) communicates with swelling gasbag (3), gas tube (1) is wrapped in the periphery of drug feeding pipe (2), gas tube tube head (11) extends from separating a backward side near the place of drug feeding pipe tube head (21), one side breathing space (31) of swelling gasbag (3) terminates in the other end tube head district (22) of drug feeding pipe (2), and drug feeding pipe (2) is provided with medicine outlet hole (23) in Gai Duan tube head district (22), described gas tube tube head (11) is or/and drug feeding pipe tube head (21) is provided with check valve (4), this check valve (4) comprises overcoat (41) and inner core (42), gas tube (1) tube wall is sandwiched in inner core (42) outside by overcoat (41), overcoat (41) is provided with only tooth (43), the bulge loop (45) that only tooth (43) is established with inner core (42) outer ring mates, this bulge loop (45) is horn-like on section, at inner core (42) from overcoat (41) one thrusters enter, bulge loop (45) elastic sliding is only crossed and is just locked in overcoat (41) after tooth (43), and gas tube (1) tube wall has also increased the compactness between individual cover and inner core, in inner core (42), there is a horn-like cavity, in cavity, place a cork, cross underframe (45) has been set up in the below of cavity, cork (44) is limited in horn-like cavity movable, cork (44) is small top and big bottom, cavity is exposed in upper part, lower end is less than cavity, but the excessive part of top and bottom just can be blocked the horn mouth of horn-like cavity, this cork (44) periphery in the time of compression forms space connects inner core (42) passage.

At gas tube (1), just near the place of breathing space (3), the some places of drug feeding pipe (2) tube wall extends to form insecticide-spraying hole (24) laterally.

Principle is as follows:

Syringe heads into inner core (42) and makes cork (44) compression, after compression, because the cause of horn-like cavity connects passage, like this, syringe injects air or normal saline, air or normal saline are in gas tube (1) enters into swelling gasbag (3), swelling gasbag (3) is expanded, the amount of now injecting is part, be put in cervical department by some tong-like equipment again, continue again afterwards to inject air or normal saline to limited amount, in the meantime and finish, when syringe departs from inner core (42), cork (44) recovers prototype, the air backwashing from swelling gasbag (3) or normal saline push up cork (44) laterally in inner core (42), because of the cause of horn-like cavity, the upper end horn mouth of the horn-like cavity of inner core (42) is blocked in cork (44) lower end, so just there will not be the situation of gas leakage or leakage, save and re-used the trouble that plug is blocked.

And in the time of medication, can medicine be injected into medicine outlet hole (23) or insecticide-spraying hole (24) by drug feeding pipe tube head (21), can solve the medication demand at intrauterine and cervix uteri place.

As meet some medicines and may have the excessive situation of returning, therefore also establish check valve (4) at drug feeding pipe tube head (21).
