Description

Postpartum vagina blood adsorber

Technical Field

The utility model relates to the field of medical equipment, concretely relates to postpartum vagina blood adsorber.

Background

When women are delivered, the perineum is cracked or cut to different degrees frequently, the wound needs to be sutured after the delivery is finished, but at the moment, the uterus contracts, blood is continuously leaked from the uterine cavity, and therefore the wound cannot be fully exposed in the suturing process, and the suturing visual field is influenced.

Chinese utility model patent No. 201920619845.7 discloses a postpartum vagina aspirator, it pushes outer pipe front end in the lying-in woman vagina earlier, then bulldozes the thumb and impels the clamping ring and make interior propulsion pipe push forward to release the absorption strip by the multi-disc opening part of outer pipe, the absorption strip is stayed in the vagina, the other end of acting as go-between of absorption strip rear end is stayed outside the vagina, takes out outer pipe at last, the absorption strip absorbs the blood of palace chamber discharge. In the above patent, the absorbent strip is pushed out into the vagina through the multi-petal opening of the outer catheter, and because the multi-petal opening is of an expandable or contractible structure, the absorbent strip has the following defects:

1. the multi-petal opening is of a claw structure after being opened, and the contraction strip is made of soft water-absorbing material due to certain force of contraction and restoration after being opened, so that the absorption strip is easily hooked by the multi-petal opening of the claw structure after being opened in the process of pushing the absorption strip into the vagina under the action of restoration force, and the absorption strip is failed to be pushed out;

2. the process of opening or contracting the multi-petal opening is the process of grabbing or stretching the claw structure, which may scrape the inner wall of the vagina or cause laceration in childbirth to cause other injuries;

3. when the front end of the outer catheter is pushed into the vagina of a lying-in woman, the multi-flap opening is pressed towards the inner side of the outer catheter, the multi-flap opening is possibly folded and damaged towards the inner side of the outer catheter under the action of the pressure, and the quality of the multi-flap opening is hard, so that discomfort is caused when the front end of the outer catheter is pushed into the vagina of the lying-in woman;

4. when the absorption strip is pushed out through the multi-petal opening, one of the petals of the multi-petal opening is deformed too much and is broken possibly due to the fact that the pushing force is too violent or the force is uneven, and new medical problems can be caused when the broken petals fall into the vagina;

5. the absorption strip is pulled out through the stay wire after absorbing blood, because the absorption strip can become heavy and soft after absorbing blood, the stay wire is only connected with the rear end of the absorption strip in addition, and when the stay wire is pulled, the absorption strip is easy to break and leave behind in the vagina.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in figure 1, the postpartum vagina blood adsorber comprises an outer catheter 1, a piston 2, an inner push-pull tube 3 and an absorption strip 4. The piston 2 is arranged in the outer guide pipe 1 in a back-and-forth sliding mode, the front end of the inner push-pull pipe 3 is fixedly connected with the piston 2, and the rear end of the inner push-pull pipe extends to the outside of the rear end of the outer guide pipe 1 and is used for pushing or pulling the piston 2 forwards and backwards to slide in the outer guide pipe 1. The rear end of the inner push-pull pipe 3 is fixed with an annular push-pull block 9, and two sides of the rear end of the outer catheter 1 are respectively fixed with a baffle 10 for holding food fingers and middle fingers when the inner push-pull pipe 3 is pushed forwards.

The absorbent strip 4 is located in the middle inside the outer duct 1 and corresponds to the front side of the piston 2. The blood adsorber further comprises a balloon 5 and a hose 6, as shown in fig. 2, the front part of the balloon 5 is a semi-spherical structure with a radial dimension matching the outer diameter of the outer catheter 1, the rear part of the balloon is a cylinder matching the inner diameter of the front end of the outer catheter 1, and the front part of the balloon 5 is located at the front side of the outer catheter 1, and the rear part of the balloon is located inside the front end of the outer catheter 1. The front end of the hose 6 is communicated with the rear end of the air bag 5, and the rear end of the hose freely penetrates through the absorption strip 4, the piston 2 and the inner push-pull pipe 3 in sequence and is connected with a valve 7 for inflating or deflating the air bag 5.

As shown in fig. 3, a cylindrical neck 8 corresponding to the rear part of the balloon 5 and recessed towards the outer side of the outer catheter 1 is arranged in the front end of the outer catheter 1, and the rear part of the balloon 5 is positioned in the neck 8.

When the vaginal dilator is used, the front part of the outer catheter 1 is inserted into a corresponding position in a vagina, and in the process of inserting the front part of the outer catheter 1 into the vagina, the air bag 5 contacts the inner wall of the vagina, so that the softness of the air bag does not bring strong discomfort to a parturient. In addition, the air bag 5 is clamped at the front end of the outer catheter 1 by the limit of the clamping groove 8, and cannot be displaced in the process of inserting the front part of the outer catheter 1 into the vagina. When the front part of the outer catheter 1 is inserted, the valve 7 is opened and the gas in the air bag 5 is exhausted through the hose 6. Because the air bag 5 is made of thin film materials, the air bag 5 shrinks into a thin film piece after the air is discharged, namely, the front end of the outer catheter 1 is opened. Then the forefinger and the middle finger respectively push the two baffles 10 forwards and push the piston 2 forwards by pressing the push-pull block 9 with the thumb, the piston 2 pushes the absorbing strip 4 in the outer catheter 1 and the thin film piece formed by the contraction of the air bag 5 into the vagina while pushing the piston 2 forwards, at the moment, the outer catheter 1, the piston 2 and the inner push tube 3 are withdrawn backwards from the vagina, and the absorbing strip 4 is left in the vagina to absorb blood. After the blood absorption is finished, the hose 6 is pulled backwards manually, and the hose 6 drives the film piece formed by the contraction of the air bag 5 to move backwards. Since the absorbent strip 4 is spirally wound around the outside of the hose 6 in a front-back manner, the front end of the absorbent strip 4 is fixedly connected with the rear end of the air bag 5, and the rear end of the absorbent strip 4 is fixedly connected to the corresponding position on the hose 6, during the process of pulling the hose 6 backward, the front part of the absorbent strip 4 is pushed by the film sheet contracted by the air bag 5 to move backward, the hose 6 drives the rear part of the absorbent strip 4 to move backward, thereby ensuring that the absorbent strip 4 is completely pulled out and preventing the absorbent strip 4 from being disconnected during the pulling process. Of course the film sheet into which the balloon 5 is contracted can also be pulled out.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
