Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a novel hemostatic water bag. Background Technology
[0002] Postpartum hemorrhage is the leading cause of maternal death, especially in remote and underdeveloped areas. Clinically, for postpartum hemorrhage that is unresponsive to uterotonic agents, a hemostatic balloon can be used to compress and stop the bleeding, thus avoiding open surgery and preserving the uterus. After the hemostatic balloon is placed, it generates hydrostatic pressure from inside the uterine cavity to outside the uterine cavity. This pressure is greater than the uterine artery pressure, which can achieve the effect of compression and hemostasis.
[0003] For example, the authorization announcement number "CN221814084U" describes a type of intrauterine hemostatic water-filled balloon. The sprayed medication is diffused, resulting in a larger and more uniform contact area with the uterine cavity. This allows for dual hemostasis through the water-filled balloon and the hemostatic medication, enhancing the hemostatic effect. Existing intrauterine hemostatic water-filled balloons are designed to add hemostatic medication to the inside of the valves and spray it into the patient's uterus to improve the hemostatic effect. However, the entire intrauterine hemostatic water-filled balloon is only designed to stop bleeding by expanding with water and compressing the arteries with air. However, if there is massive bleeding in the uterus, the blood will be blocked in the uterus by the hemostatic water-filled balloon and cannot be discharged. Even if the bleeding can be stopped, the accumulated blood cannot be discharged in time and will irritate the wound and the uterine wall, causing greater burden and harm to the patient and affecting the effectiveness of the intrauterine hemostatic water-filled balloon.
[0004] Meanwhile, existing intrauterine hemostatic balloons use double-layered hemostatic cotton pads to adhere tightly to the vaginal opening. While these pads can absorb blood seeping from the vaginal opening, they are simply round cotton pads with limited absorption capacity. Furthermore, their round shape makes it difficult to conform to the curvature of the vaginal opening, leading to side leakage in areas where they are not properly fitted. This can also allow external bacteria and air to enter the vaginal opening and cause infection, resulting in a less than ideal hemostatic effect of the intrauterine hemostatic balloon. Utility Model Content
[0005] The purpose of this invention is to solve the problems of poor performance and mediocre hemostatic effect of existing intrauterine hemostatic water balloons, and to propose a new type of hemostatic water balloon.

[0013] The novel hemostatic water-filled balloon proposed in this utility model has the following advantages: the drainage vessel can be connected to an external hemostatic agent at the end of the connecting head. The external medication is injected into the through-hole along the drainage vessel. The water-soluble membrane is melted upon contact with the liquid medication, and the medication is sprayed into the uterus through the through-hole to accelerate hemostasis.

Pulling the needle in the opposite direction can drain excess blood along the open through hole 72 and the drain tube 74. The medication and blood flow inside the drain tube 74 can be shut off at any time using the control valve 75. The drain tube 74 is fixedly connected inside the guide tube 1.
[0028] The water-soluble membrane 73, rolled into a ball, is inserted into the through-hole 72 to seal it. The draining vessel 74 can be connected to an external hemostatic agent at the end of the connecting head 76. The hemostatic agent can be a liquid such as ethamsylate injection solution that is easy to deliver. In this way, the external drug solution is injected into the through-hole 72 along the draining vessel 74. The water-soluble membrane 73 will dissolve when it comes into contact with the liquid drug. The drug solution can then be sprayed into the uterus through the through-hole 72 to accelerate hemostasis. After the drug solution is sprayed, the connecting head 76 can be used to connect a blood-drawing needle to the rear of the draining vessel 74. Pulling the needle in the opposite direction can drain excess blood along the open through-hole 72 and the draining vessel 74. The draining vessel 74 can be used to replenish hemostatic drugs and control uterine bleeding, effectively achieving multiple functions and greatly improving the use effect of the new hemostatic water balloon.

[0035] Working principle:
[0036] The new type of hemostatic water balloon is used in the treatment of postpartum hemostasis. Postpartum hemorrhage is a common and serious complication in obstetrics. Water balloon tamponade is a commonly used hemostasis method. First, the water balloon is placed in the uterine cavity through the vagina to ensure that the position is correct. Then, air is inflated into the water balloon through the inflation tube to stabilize it in the uterine cavity. The expanded water balloon is used to compress and stop the bleeding.
[0037] The placement and hemostatic structure of the novel hemostatic water-filled balloon:
[0038] The leak-proof ring 44 is made of medical rubber material. The leak-proof ring 44 fills the gap at the connection between the connecting pipe 43 and the delivery pipe 45. In this way, the water inlet 41 can be connected to the external disinfected water source. After the stop valve 42 is opened, the water inlet 41 injects disinfected clean water into the hemostatic water bladder 3. Then, it enters the inside of the expansion water bladder 62 through multiple water injection holes 63. The two ends of the two connecting seats 61 are fixedly connected to the two ends of the hemostatic water bladder 3. The water injection holes 63 facilitate the entry of clean water into the inside of the expansion water bladder 62. The expansion water bladder 62 is made of clean and disinfected rubber material. After water is injected, it can expand in volume, which can conveniently compress and block the uterine bleeding opening.
[0039] The structure of the novel hemostatic water-filled sac for draining blood and replenishing hemostatic drugs:
[0040] The curved head 71 is made of PVC plastic with a curved front end. The surface of the curved head 71 is smooth and does not easily scratch the human body. The through hole 72 is used to inject medicine and drain accumulated blood. The water-soluble membrane 73 is made of PVA water-soluble film. Before the hemostatic water bag 3 enters the human body, the water-soluble membrane 73, which is rolled up, is inserted into the through hole 72 to seal it. The draining vessel 74 can first connect the external hemostatic medicine to the end of the connecting head 76. The hemostatic medicine can be a liquid that is easy to transport, such as ethamsylate injection. In this way, the external medicine is injected into the through hole 72 along the draining vessel 74. The water-soluble membrane 73 will melt when it comes into contact with the liquid medicine. In this way, the medicine can be sprayed into the uterus through the through hole 72 to accelerate hemostasis in conjunction with the medicine.
[0041] After the medication is sprayed, the blood-drawing needle can be connected to the back of the drain tube 74 via the connector 76. Pulling the needle in the opposite direction can drain excess blood along the open hole 72 and the drain tube 74. The medication and blood flow inside the drain tube 74 can be shut off at any time using the control valve 75.
[0042] The hemostatic cotton pad of the new hemostatic water sac has a blood-absorbing structure:
[0043] The positioning plate 51 is a vertical plate that fits in the middle of the guide tube 1 and can push and position the front hemostatic cotton pad 54. The absorbent layer 52 is made of pure compressed cotton. The absorbent layer 52 can absorb more blood and improve the hemostatic performance of the front hemostatic cotton pad 54. The elastic layer 53 is made of stacked PVC plastic layers. The elastic layer 53 wraps around the outside of the absorbent layer 52 and can connect the back of the hemostatic cotton pad 54 and the front of the positioning plate 51. The elastic layer 53 can generate a small amount of compression elasticity, which can be used with the front hemostatic cotton pad 54 to adapt to the needs of different patients. The hemostatic cotton pad 54 adopts a front arc-shaped bending design and is made of pure cotton compressed cloth. The arc-shaped hemostatic cotton pad 54 can better fit the shape of the vaginal opening.
