Description

A hemostatic balloon for obstetrics and gynecology

technical field

The utility model relates to the field of surgical mechanical devices, in particular to a hemostatic balloon for obstetrics and gynecology.

Background technique

For uterine atony bleeding, strengthening uterine contraction is the most rapid and effective method of hemostasis, including massaging the uterus, applying uterotonic agents (oxytocin, prostaglandin), etc. Bleeding can be stopped by uterine packing and compression. In the past, gauze packing in the uterine cavity is a common method to stop bleeding. Gauze is a cheap and effective way to stop bleeding. However, "gauze left over" has always troubled medical staff and is also one of the reasons for medical disputes. one. In addition, it may cause uterine damage and intrauterine infection.

In 2014, Shenzhen Yixinda Medical New Technology Co., Ltd. took the lead in registering the product "one-time use balloon uterine stent" in China, using a stuffed balloon to treat postpartum hemorrhage. The external hydrostatic pressure (maximum water injection volume can be 500ml), the pressure is greater than the uterine artery pressure can play the purpose of oppressive hemostasis.

However, the existing hemostatic balloon needs to be immersed in normal saline in advance, and then inserted into the uterine cavity after it swells. This method not only takes time and effort, but also causes pain to the patient when inserted. , we designed a hemostatic balloon for obstetrics and gynecology.

Example 1:

Please refer to Figure 1-3, a hemostatic balloon for obstetrics and gynecology, including a catheter 1 and a hemostatic bag 2, characterized in that: the hemostatic bag 2 is provided with a through hole, and the inside of the hemostatic bag 2 passes through the through hole and the guide tube. The outer wall of the flow tube 1 is fixedly connected, the inside of the hemostatic bag 2 is provided with a cavity, the inner wall of the cavity is fixedly connected with a breakable bag 10, the inside of the breakable bag 10 is filled with physiological saline 11, and the inner wall of the flow guide tube 1 is slidably connected There is a pulling wire 4 , one end of the pulling wire 4 runs through the inside of the breakable bag 10 , the other end of the pulling wire 4 extends to the outside of the draft tube 1 , and one end of the pulling wire 4 located in the breakable bag 10 is fixedly connected with a barb 41 .

The traditional hemostatic balloon needs to be filled with normal saline first, so that it can expand, thereby generating a hydrostatic pressure from the uterine cavity to the outside, compressing the muscle wall and blood vessels, and reducing the amount of uterine bleeding;

This design is different from it in that: the unexpanded hemostatic bag 2 is first sent into the patient's uterine cavity, which saves time and effort. Compared with the existing technology, it reduces the pain of the patient and improves his medical experience. Pull the traction wire, and the breakable bag can be punctured through the barb, and the physiological saline inside the breakable bag can be absorbed by the hemostatic sac, causing it to expand, and the blood in the uterus can flow out of the uterus through the blood diversion tube 1 , does not affect the hemostatic effect of the hemostatic balloon device itself.

The drawing wire 4 adopts unrepaired steel material, and its radius is 0.5-2 millimeters.

The use of stainless steel can prevent it from rusting and affect the next use.

The outer end of the diversion tube 1 is fixedly connected with a communication pipe 6 , and one end of the communication pipe 6 is fixedly connected with an air storage bag 5 , the air storage bag 5 is made of rubber, and the inner wall of the communication pipe 6 is fixedly connected with a control valve 12 .

During specific work: the air storage bag 5 can be pressed to release the internal gas, and then the control valve 12 is closed. At this time, the inside of the negative pressure tube 9 is in a negative pressure state, and the blood will flow out from the guide tube 1, and when the blood no longer flows from the guide tube When the flow tube 1 flows out, the control valve 12 can be opened, and the negative pressure of the air storage bag 5 can be used to suck out the blood congestion from the negative pressure tube 9 .

Example 2:

Please refer to Figures 4-5. The difference between this embodiment and Embodiment 1 is that the following technical features are added: the inner wall of the flow guide tube 1 is fixedly connected with a negative pressure tube 9, and the inner wall of the flow guide tube 1 is close to the connecting pipe 6. The liquid inlet hole 13, the negative pressure pipe 9 and the communication pipe 6 communicate with each other.

The outer end of the communication pipe 6 is fixedly connected with an air outlet pipe 8 , and the inner walls of the air outlet pipe 8 and the communication pipe 6 are both provided with check valves.

For avoiding that it is difficult to suck out all the congestion at one time, an air outlet pipe 8 can be provided. By arranging two one-way valves, when the air storage bag 5 is pressed again, the internal gas escapes from the air outlet pipe, and the inside of the negative pressure pipe 9 is still negative. In the pressure state, you can continue to suck the congestion in the uterine cavity.

The outer end of the draft tube 1 is also fixedly connected with a liquid outlet tube 7 , and the bottom end of the draft tube 1 is fixedly connected with a waste liquid bag 3 .

Specifically, a control valve is also arranged inside the liquid outlet pipe 7 .

By arranging the waste liquid bag 3, the blood drawn from the drainage tube 1 can be temporarily stored, and when the waste liquid bag 3 is full, the control valve 12 of the liquid outlet pipe 7 can be forced to open, and the blood can be discharged from the liquid outlet pipe. 7 flow out.

The above description is only a preferred embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Anyone familiar with the technical field within the technical scope disclosed in the utility model, according to the technical solution of the utility model and its improvement concept to make an equivalent replacement or change, shall be covered in the protection scope of the utility model.
