Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a uterine hemostasis balloon device. Background Technology

[0002] Obstetric patients may experience significant bleeding, such as due to trauma, miscarriage, vaginal delivery, or cesarean section, or due to various other causes such as placental abruption, placenta previa, placenta accreta, placenta penetrating or accreta, or coagulation disorders. Currently, treatment methods for obstetric hemorrhage include: blood products and / or pharmacological interventions (such as coagulation mediators, uterine contraction agents), uterine massage and compression sutures, surgery, and interventional radiology procedures. Among these, packing the uterus with gauze is an effective and rapid method for hemostasis; however, the preparation and packing of gauze are difficult, and the pressure on the uterine cavity wall is uneven, easily creating dead space and leading to hemostasis failure. Furthermore, the surface of the gauze is relatively rough and lacks smoothness; if any loose threads occur, they will contaminate the uterine environment and increase patient pain.

[0003] To address the aforementioned issues, balloon catheters specifically developed for managing postpartum hemorrhage have emerged on the market. However, traditional intrauterine hemostatic balloons are typically cylindrical or spherical, which do not conform to the actual shape of the uterus. Furthermore, the balloon is often placed in the lower segment of the uterine cavity, or even in the lower segment and cervical canal, making it prone to slippage due to the lack of fixation at the cervix. This is especially true for patients who have undergone vaginal delivery or cesarean section after cervical dilation, as cervical relaxation and / or cervical lacerations increase the risk of slippage. Accordingly, in recent years, hemostatic balloons adapted to the size and shape of the uterine cavity have been developed, often incorporating a cervical shield to prevent slippage. For example, patent application number 202121718055.8 discloses a novel uterine and cervical hemostatic balloon that offers both excellent hemostatic effect and the ability to more quickly and effectively guide blood retained in the uterus out, while also being safer and more convenient to use.

[0004] However, the existing intrauterine hemostasis balloons have the following shortcomings: Traditional intrauterine hemostasis balloons generally use single-lumen balloons. Since most pregnant women are in a delivery position with the cervix facing down, and the weight of the balloon itself after being filled with water is always downward, the balloon can only effectively compress and stop bleeding on the inner wall of the lower half of the uterine cavity. If bleeding occurs in the upper half of the inner wall of the uterine cavity, the existing intrauterine compression balloons, even after being filled with water, are difficult to compress the bleeding site in the upper part, and may even aggravate the pressure on the inner wall of the lower half of the uterine cavity. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a uterine cavity hemostasis balloon device, which can effectively compress the uterus in all directions, thereby effectively improving the hemostasis effect.

[0006] According to a first aspect of the present invention, a uterine hemostasis balloon device includes a balloon and a catheter assembly. The catheter assembly includes a sheath, drainage tubes disposed within the sheath, and multiple injection tubes. The balloon includes a first balloon, a second balloon, and a third balloon that are sequentially fitted onto the sheath from bottom to top. The volume of the first balloon, the volume of the second balloon, and the volume of the third balloon increase sequentially.

[0007] The top end of the sleeve is provided with a drainage hole, and the two ends of the drainage tube are respectively connected to the drainage hole and the drainage device;

[0008] Each of the injection tubes connects the first balloon, the second balloon, and the third balloon to the injection device, respectively;

[0009] The extensibility of the second balloon is greater than that of the first balloon and the third balloon;

[0010] When the balloon is filled with filling material and is in a state of full expansion, the first balloon, the second balloon, and the third balloon are stacked in sequence from bottom to top.

[0011] The intrauterine hemostasis balloon device according to the embodiments of this utility model has at least the following beneficial effects: by setting multiple balloons, the first balloon provides support, and the inflated second balloon provides an upward force to the third balloon, so that the third balloon can compress and stop bleeding in the upper part of the uterine cavity. At the same time, under the action of the gravity of the third balloon and the support force of the first balloon, the second balloon expands and extends outward, so that the second balloon can compress the side wall of the uterine cavity, thereby achieving a better hemostasis effect. The structure is safe and simple.

[0012] According to some embodiments of the present invention, when the balloon is in a state of inflation, the overall shape of the balloon is a structure that is larger at the top and smaller at the bottom.

[0013] According to some embodiments of the present invention, when the first balloon is filled with a filling material, the expansion and stretching direction of the first balloon is to extend and expand sequentially from the lower end to the upper end along the length direction of the sleeve.

[0014] According to some embodiments of the present invention, when the third balloon is filled with filler, the highest point of the third balloon is higher than the drainage hole.

[0015] According to some embodiments of the present invention, the third balloon includes a plurality of first sub-balloons that are sequentially connected and arranged around the tube sleeve, and each of the first sub-balloons is connected to the injection device through the injection tube.

[0016] According to some embodiments of the present invention, the second balloon includes a plurality of second sub-balloons that are sequentially connected and arranged around the sleeve, and each of the second sub-balloons is connected to the injection device through the injection tube.

The injection ports of the plurality of first sub-balloons, the plurality of second sub-balloons and the injection port of the first balloon, which are sleeved on the outer periphery of the sleeve, are respectively connected to the injection holes.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] refer to Figure 1 , Figure 2 as well as Figure 3 As shown, the intrauterine hemostasis balloon device according to the present invention includes a balloon and a catheter assembly. The catheter assembly includes a sleeve 210, drainage tubes 220 disposed within the sleeve 210, and multiple injection tubes 230. The balloon includes a first balloon 110, a second balloon, and a third balloon, which are sequentially fitted onto the sleeve 210 from bottom to top. The volume of the first balloon 110, the volume of the second balloon, and the volume of the third balloon increase sequentially.

[0032] The top end of the sleeve 210 is provided with a drainage hole 211, and the two ends of the drainage pipe 220 are respectively connected to the drainage hole 211 and the drainage device (not shown in the figure);

[0033] Each injection tube 230 connects the first balloon 110, the second balloon, and the third balloon to the injection device (not shown in the figure);

[0034] The extensibility of the second balloon is greater than that of the first balloon 110 and the third balloon.

[0035] When the balloon is filled with filling material and is in a state of full inflation, the first balloon 110, the second balloon, and the third balloon are stacked in sequence from bottom to top.

[0036] In practical use, multiple balloons are set up. The first balloon 110 provides support, while the inflated second balloon provides an upward force to the third balloon, enabling the third balloon to compress and stop bleeding in the upper part of the uterine cavity. At the same time, under the weight of the third balloon and the supporting force of the first balloon 110, the second balloon expands and extends outward, thus enabling the second balloon to compress the side wall of the uterine cavity, thereby achieving a good hemostatic effect. The structure is safe and simple.

[0037] In some specific embodiments of this utility model, it may also have the following additional technical features: when the balloon is in a state of inflation, the overall shape of the balloon is a structure that is larger at the top and smaller at the bottom.

[0038] Specifically, the overall shape of the balloon is similar to an inverted pear, which allows it to fit more closely to the uterine cavity while providing better compression without putting too much pressure on the uterine opening.

[0039] In some specific embodiments of this utility model, it may also have the following additional technical features: when the first balloon 110 is filled with a filling material (not shown in the figure), the expansion and stretching direction of the first balloon 110 is to extend and expand sequentially from the lower end to the upper end along the length direction of the sleeve 210.

[0040] Specifically, the expansion direction of the first balloon 110 is mainly concentrated along the axial direction of the sleeve 210, while the radial direction of the sleeve 210 is relatively small. On the one hand, this can reduce the pressure on the uterine cavity, and on the other hand, it can move towards the second balloon to support the second balloon.

[0041] In some specific embodiments of this utility model, it may also have the following additional technical features: when the filling material is injected into the third balloon, the highest point of the third balloon is higher than the drainage hole 211.

[0042] The above design ensures the drainage effect while embedding the drainage tube 220 into the third balloon, thus preventing the drainage tube 220 from protruding outside and poking the uterine cavity wall, causing discomfort.

[0043] In some specific embodiments of this utility model, it may also have the following additional technical features: the third balloon includes a plurality of first sub-balloons 121 that are sequentially connected and arranged around the sleeve 210, and each first sub-balloon 121 is connected to the injection device through an injection tube 230.

[0044] In some specific embodiments of this utility model, it may also have the following additional technical features: the second balloon includes a plurality of second sub-balloons 131 connected in sequence and arranged around the sleeve 210, and each second sub-balloon 131 is connected to the injection device through an injection tube 230.

[0045] With the multiple sub-balloons designed as described above, more filler can be injected into one or more sub-balloons according to actual needs, thereby more precisely compressing the bleeding point.

[0046] In some specific embodiments of this utility model, it may also have the following additional technical features: the drainage tube 220 and the multiple injection tubes 230 are all independent tube structures.

[0047] In some specific embodiments of this utility model, it may also have the following additional technical features: the sleeve 210 is provided with a plurality of injection holes 212, each injection tube 230 is connected to each injection hole 212 in a one-to-one correspondence, and the injection ports 140 of the plurality of first sub-balloons 121, the injection ports 140 of the plurality of second sub-balloons 131 and the injection port 140 of the first balloon 110, which are sleeved on the outer periphery of the sleeve 210, are respectively connected to the injection holes 212.

[0048] Specifically, each injection tube 230 is sealed to the injection port 212, and each injection port 140 is sealed to the injection port 212. This design prevents the injection tube 230 from extending into the balloons, thus avoiding protrusions within the balloons and discomfort during insertion into the uterine cavity.

[0049] In some specific embodiments of this utility model, it may also have the following additional technical features: the first balloon 110 is filled with gas.

[0050] In some specific embodiments of this utility model, it may also have the following additional technical features: both the first sub-balloon 121 and the second sub-balloon 131 are filled with liquid.

[0051] By filling the first balloon 110 with gas, which can be air, carbon dioxide, oxygen, or a mixture of carbon dioxide and oxygen, the gas density is relatively low compared to the liquid density, which can effectively reduce the weight of the entire balloon. Under the action of gravity, it will not excessively compress the lower half of the uterine cavity. Then, by injecting saline or other suitable liquids into the second and third balloons, the side walls and top walls of the uterine cavity are compressed, thereby achieving a better hemostatic effect.

[0052] It should be noted that both the drainage device and the injection device are technical means commonly used by those skilled in the art, and their specific structures and principles will not be elaborated here.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
