AI Technical Summary
In existing techniques, controlling intrauterine bleeding is difficult, and the use of drugs to promote uterine contractions and the irregularity of the filling material result in time-consuming and laborious procedures with poor hemostatic effects.
A uterine cavity hemostat was designed, comprising a connecting tube and a compression balloon. Hemostasis is achieved by compression of the balloon, and after hemostasis, a water supply mechanism is used to inject clean water into the uterine cavity to moisten it and prevent tearing at the hemostasis site.
It achieves efficient hemostasis, avoids secondary bleeding, simplifies the operation process, and reduces the workload of medical staff.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, specifically to a uterine hemostatic device. Background Technology
[0002] Intrauterine bleeding during obstetric and gynecological surgery is a common and frequently occurring disease in clinical practice. If not controlled in time, it can lead to maternal death.
[0003] Currently, the main clinical methods to control bleeding are to use medication to promote uterine contraction or to pack gauze and cotton wool into the uterine cavity. These methods are very troublesome, time-consuming, and laborious, which increases the workload for medical staff. In addition, the irregular geometric shape of the packing material makes it difficult to adhere tightly to the uterine wall, which is not conducive to effective hemostasis. Utility Model Content
[0004] The purpose of this invention is to provide a uterine hemostatic device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a uterine hemostat, comprising a connecting tube and a compression balloon, wherein one end of the connecting tube is provided with a first connector through a first fixing plate, the first connector being in communication with the interior of the connecting tube, and the other end face of the connecting tube is provided with a second fixing plate, wherein the connecting tube has multiple ventilation holes on the side wall near the second fixing plate, and the compression balloon is sleeved on the outer side of the end of the connecting tube near the second fixing plate, and the compression balloon is in communication with the interior of the connecting tube through the ventilation holes.
[0006] Preferably, the second fixing plate has a cavity inside, and the second fixing plate has a through hole on the side surface facing the connecting pipe that communicates with the cavity, and the cavity communicates with the fixing pipe inside the connecting pipe.
[0007] Preferably, a second connector is provided on the side of the first fixing plate, and the second connector is connected to the fixing pipe.
[0008] Preferably, the interior of the connecting pipe is provided with a conveying channel and a sewage discharge channel through a partition, and the conveying channel is connected to the vent and the first connector.
[0009] Preferably, the connecting pipe has multiple drain ports that communicate with the sewage discharge channel on its wall, and the drain ports are located on the side of the compression airbag away from the first fixed plate.
[0010] Preferably, the first fixing plate is further provided with a third connector, which is connected to the sewage discharge channel.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a second fixing plate, a cavity is set inside the second fixing plate and a perforation communicating with the cavity is provided. At the same time, the cavity is connected to a water supply mechanism through a fixing tube, a second connector, and a conduit. After hemostasis is completed, clean water is slowly injected into the uterine cavity through the water supply mechanism to moisten the uterine cavity, avoiding the subsequent contraction of the compression balloon that would cause tearing at the hemostasis site, and effectively preventing secondary bleeding.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-2 This utility model provides a technical solution: a uterine hemostat, including a connecting tube 1 and a compression balloon 2. One end of the connecting tube 1 is provided with a first connector 4 through a first fixing plate 3. The first connector 4 communicates with the interior of the connecting tube 1. The other end face of the connecting tube 1 is provided with a second fixing plate 5. The connecting tube 1 has a plurality of ventilation holes 6 on the side wall near the second fixing plate 5. The compression balloon 2 is sleeved on the outside of the end of the connecting tube 1 near the second fixing plate 5, and the compression balloon 2 communicates with the interior of the connecting tube 1 through the ventilation holes 6.
[0017] The second fixing plate 5 has a cavity 7 inside. The second fixing plate 5 has a through hole 8 on the side surface facing the connecting pipe 1 that communicates with the cavity 7, and the cavity 7 communicates with the fixing pipe 9 inside the connecting pipe 1.
[0018] The first fixing plate 3 has a second connector 10 on its side, and the second connector 10 is connected to the fixing tube 9.
[0019] Both the first connector 4 and the second connector 10 are connected to conduits, and the other end of the conduits is connected to an air supply mechanism and a water supply mechanism, respectively. A valve is installed on the conduit corresponding to the first connector 4.
[0020] The interior of the connecting pipe 1 is provided with a conveying channel 11 and a sewage discharge channel 12 through a partition. The conveying channel 11 is connected to the vent hole 6 and the first connector 4.
[0021] The connecting pipe 1 has multiple drain ports 13 that communicate with the drain channel 12. The drain ports 13 are located on the side of the compression airbag 2 away from the first fixed plate 3.
[0022] The first fixing plate 3 is also provided with a third connector 14, which is connected to the sewage channel 12, and the conduit end corresponding to the third connector 14 is connected to a negative pressure mechanism.
[0023] Specifically, when using this utility model, the first connector 4 and the second connector 10 are placed in the uterine cavity through the conduit and the connecting pipe 1, and the compression airbag 2 and the second fixing plate 5 are placed in the uterine cavity, with the second fixing plate 5 at the bottom of the uterine cavity. The gas generated by the gas supply mechanism is delivered to the inside of the compression airbag 2 through the first connector 4 and the delivery channel 11. The expanded compression airbag 2 compresses the uterine cavity to stop bleeding. During this process, the negative pressure generated by the negative pressure mechanism causes the dirty blood in the uterine cavity to be discharged from the sewage outlet 13 and the sewage channel 12.
[0024] After hemostasis is completed, clean water is slowly delivered into the uterine cavity through the water supply mechanism. The clean water is slowly discharged through the fixed tube 9, cavity 7, and perforation 8, and is located between the compression balloon 2 and the uterine cavity to moisten the contact area. Then, the valve on the corresponding catheter of the first connector 4 is opened to allow the gas in the compression balloon 2 to be slowly discharged and separated from the cavity wall. Finally, the entire device is removed from the uterine cavity.
