Description

Technical Field

[0001] This utility model belongs to the field of medical supplies, specifically relating to a hemostatic bag to prevent uterine water-filled balloon slippage. Background Technology

[0002] Currently, in clinical practice, for postpartum women who have undergone cesarean section or vaginal delivery and whose uterine body has contracted well but who are experiencing bleeding in the lower uterine segment, the common method is to use a uterine balloon pack (i.e., a hemostatic balloon). Existing uterine balloons need to be inserted into the uterine cavity, and then the balloon is inflated with water or air, causing its outer wall to press against the inner wall of the uterine cavity, thereby achieving hemostasis. However, due to the current technology, after the balloon is inserted into the patient's uterine cavity, as the uterus contracts and recovers post-operatively, it is easy for the balloon to be pushed towards the uterine outlet, leading to poor hemostasis. Therefore, the current technology has the problem of the hemostatic balloon easily slipping out of the uterine cavity. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a hemostatic sac to prevent the uterine water sac from slipping out, thus solving the problem that the hemostatic sac in the prior art is prone to slipping out of the uterine cavity.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A hemostatic sac to prevent uterine water-filled sac from slipping out, comprising a ring-shaped sac;

[0006] The capsule has an internal cavity to hold liquid, and the capsule is made of an elastic material;

[0007] A water injection tube is connected to the bladder body, and the water injection tube is connected to the cavity inside the bladder body. A switch valve is installed on the water injection tube.

[0008] The capsule contains multiple elastic rods that are evenly distributed in a ring around the central axis of the capsule. The elastic rods can bend elastically and are placed coaxially with the central axis of the capsule. One end of each elastic rod is fixed to the inner peripheral wall of the capsule near the central axis of the capsule.

[0009] The principle and effect of the above technical solution are as follows:

[0010] Before inserting the cyst into the uterus, bend the ends of the elastic rods that are not fixed to the cyst towards the ends away from the central axis of the cyst. Then insert them into the uterus and open the valve to inject water into the cyst through the water injection tube. Inject an appropriate amount of water according to the actual diameter of the patient's uterine cavity, causing the cyst wall to expand until it squeezes and contacts the uterine cavity. This compression of the uterine cavity achieves hemostasis. At the same time, after the cyst and elastic rods are inserted into the uterus, the elastic rods rebound under their own elasticity, causing one end of the elastic rod to push the inner wall of the cyst into contact with the uterine cavity. The degree of bending of the elastic rods can adapt to the contraction or expansion of the patient's uterine cavity, effectively reducing the risk of the cyst slipping out of the uterine cavity.

[0011] When the cyst is inflated to its maximum state, the distance between the inner wall of the cyst on the side away from the central axis and the inner wall on the side closer to the central axis is set as L, and the length of the elastic rod is greater than or equal to L.

[0012] The cavity of the capsule is provided with a sleeve placed on the same axis as the capsule. The inner peripheral wall of the capsule near the central axis of the capsule is fixed to the inner peripheral wall of the sleeve. The elastic rod is fixed to the inner wall of the capsule by the sleeve instead of the sleeve.

[0013] A soft ball is fixed to the end of the elastic rod away from the sleeve;

[0014] The sleeve has multiple evenly distributed slots, each slot corresponding to a spring rod. The ends of the spring rods away from the soft ball are fixed to the groove walls of the corresponding slots.

[0015] The soft ball is made of rubber or silicone material;

[0016] A connector is fixedly connected to the end of the water injection pipe away from the bladder body.

[0017] The beneficial effects of this utility model are:

[0018] 1. Before inserting the cyst into the uterus, bend each elastic rod. After inserting it into the uterus, open the valve and inject water into the cyst through the water injection tube. Inject an appropriate amount of water according to the actual diameter of the patient's uterine cavity, so that the cyst wall expands to squeeze and contact the uterine cavity. The compression of the uterine cavity achieves hemostasis. At the same time, the elastic rod rebounds under its own elastic force, so that one end of the elastic rod pushes the inner wall of the cyst to squeeze and contact the uterine cavity. The degree of bending of the elastic rod can adapt to the contraction or expansion of the patient's uterine cavity, which can effectively reduce the slippage of the cyst from the uterine cavity.

[0019] 2. By using a sleeve, the stability of the elastic rod placement is improved, preventing the elastic rod from becoming misaligned or tilted due to the expansion of the cyst, and improving the stability of the elastic rod's compression contact with the uterine cavity, thus preventing the failure of the anti-slip effect.

[0020] The grooves allow medical staff to easily bend the elastic rod by passing their fingers through them.

[0021] 3. The soft ball at the end of the elastic rod reduces scratches on the cyst by the elastic rod. At the same time, the soft ball prevents excessive compression of the uterine cavity by the edge of the elastic rod end and further improves the anti-slip effect. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] This combination Figures 1 to 3This describes an embodiment of a hemostatic sac for preventing uterine water-filled balloon slippage. Specifically, the hemostatic sac for preventing uterine water-filled balloon slippage is constructed as a split structure, comprising a sac body 100, a water injection tube 200, and elastic rods 300. Before the sac body 100 is inserted into the uterus, the ends of the elastic rods 300 not fixed to the sac body 100 are bent away from the central axis of the sac body 100. Then, the sac body 100 is inserted into the uterus, and the valve is opened to inject water into the sac body 100 through the water injection tube 200. The amount of water injected is appropriate according to the actual diameter of the patient's uterine cavity, causing the periphery of the sac body 100 to expand to fit within the uterine cavity. The compression contact achieves hemostasis by compressing the uterine cavity. Simultaneously, after the cyst 100 and elastic rod 300 are inserted into the uterus, the elastic rod 300 rebounds under its own elastic force, causing one end of the elastic rod 300 to push the inner wall of the cyst 100 into compression contact with the uterine cavity. This makes the cyst 100 tend to move inward into the uterine cavity. Furthermore, the degree of bending of the elastic rod 300 can adapt to the contraction or expansion of the patient's uterine cavity, effectively reducing the risk of the cyst 100 slipping out of the uterine cavity.

[0028] Please refer to Figures 1 to 3 A hemostatic sac to prevent the uterine water sac from slipping off, comprising a circular sac body 100;

[0029] The capsule 100 has a cavity inside to contain liquid, and the capsule 100 is made of an elastic material;

[0030] A water injection pipe 200 is connected to the bladder body 100, and the water injection pipe 200 is connected to the cavity inside the bladder body 100. A switch valve is provided on the water injection pipe 200.

[0031] The capsule 100 has a plurality of elastic rods 300 evenly distributed in a ring around the central axis of the capsule 100. The elastic rods 300 can be elastically bent. All elastic rods 300 are placed coaxially with the central axis of the capsule 100. One end of each elastic rod 300 is fixed to the inner peripheral wall of the capsule 100 near the central axis of the capsule 100.

[0032] Preferably, the elastic rod 300 can be a round rod made of rubber or silicone material;

[0033] Before inserting the cyst 100 into the uterus, bend the ends of the elastic rods 300 that are not fixed to the cyst 100 away from the central axis of the cyst 100. Then insert them into the uterus and open the valve to inject water into the cyst 100 through the water injection pipe 200. Inject an appropriate amount of water according to the actual diameter of the patient's uterine cavity, so that the periphery of the cyst 100 expands to squeeze and contact the uterine cavity. The hemostasis effect is achieved by squeezing the uterine cavity. After the water injection is completed, close the valve. At the same time, after the cyst 100 and elastic rods 300 are inserted into the uterus, the elastic rods 300 rebound under their own elasticity, so that one end of the elastic rods 300 pushes the inner wall of the cyst 100 to squeeze and contact the uterine cavity. The bending degree of the elastic rods 300 can adapt to the contraction or expansion of the patient's uterine cavity, which can effectively reduce the slippage of the cyst 100 from the uterine cavity.

[0034] When the capsule 100 is inflated to its maximum state, the distance between the inner wall of the capsule 100 on the side away from the central axis and the inner wall on the side close to the central axis is set as L, and the length of the elastic rod 300 is greater than or equal to L; thus ensuring an effective anti-slip effect.

[0035] To prevent the elastic rod 300 from becoming misaligned due to the expansion and deformation of the cyst 100, thus causing it to lose its squeezing effect with the uterine cavity, a sleeve 400 is provided inside the cavity of the cyst 100, placed coaxially with the cyst 100. The inner peripheral wall of the end of the cyst 100 near the central axis of the cyst 100 is fixed to the inner peripheral wall of the sleeve 400. The fixed end of the elastic rod 300 to the inner wall of the cyst 100 is fixed by the sleeve 400. The sleeve 400 can effectively maintain the stability of the fixed end of the elastic rod 300 and the cyst 100, prevent the elastic rod 300 from becoming misaligned or tilted due to the expansion of the cyst 100, improve the stability of the squeezing contact between the elastic rod 300 and the uterine cavity, and prevent the failure of the anti-slip effect.

[0036] A soft ball 500 is fixed to the end of the elastic rod 300 that is away from the sleeve 400. The soft ball 500 reduces the scratches of the elastic rod 300 on the cyst body 100, avoids excessive compression of the end edge of the elastic rod 300 on the uterine cavity, and further improves the anti-slip effect.

[0037] It should be noted that during use, the fixed ends of the elastic rod 300 and sleeve 400 are located at the end closer to the inside of the uterus, and the soft ball 500 is located at the end closer to the outside of the uterus.

[0038] The sleeve 400 has a plurality of evenly distributed strip grooves 401, each corresponding to a spring rod 300. The ends of the spring rods 300 away from the soft ball 500 are fixed to the groove walls of the corresponding strip grooves 401. The strip grooves 401 make it easy for medical personnel to push the spring rods 300 to bend by passing their fingers or other tools through the strip grooves 401.

[0039] The soft ball 500 is made of rubber or silicone material to ensure its elasticity and softness.

[0040] A connector 201 is fixedly connected to one end of the water injection pipe 200 away from the bladder body 100, so that the water injection pipe 200 can be connected to an external water pipe for water injection.
