Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a puncture compression balloon and a puncture compression component. Background Technology
[0002] Percutaneous renal biopsy is a kidney biopsy procedure that involves inserting a renal needle through the skin on the back to a selected puncture point into the lower segment of the kidney to obtain a sample. It is currently the most widely used renal biopsy method both domestically and internationally, and is a key step in the pathological diagnosis of kidney diseases, especially chronic kidney diseases such as nephritis and nephrotic syndrome.
[0003] Currently, postoperative bleeding remains a major complication after puncture in clinical practice, leading to increased hospitalization time and treatment costs, and in severe cases, hemorrhagic shock. To stop bleeding at the puncture site, obstetric abdominal binders are commonly used in clinical practice for pressure hemostasis. However, under standard abdominal tightening force, the hemostatic effect of abdominal binders is not ideal. When these types of abdominal binders achieve hemostasis, the tightening force can easily cause breathing difficulties for patients while in bed. Furthermore, the size and tightening force of these types of abdominal binders are not suitable for obese patients.
[0004] Previous studies have also found that abdominal binders for renal biopsy, such as the one provided in CN115813664A, use compression balloons to compress and stop bleeding at the bleeding site. However, in clinical application, the inventors found that although such balloons can inflate and exert a certain compression effect, the balloons themselves tend to flatten after being squeezed, which weakens their compression effect and thus affects the effectiveness of compression hemostasis. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a puncture compression balloon and puncture compression components, primarily to solve the current issue of ineffective compression hemostasis after kidney biopsy.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] The first aspect of this utility model provides a puncture compression balloon, comprising:
[0008] The shaping rubber ring has a ring-shaped structure, and its inner ring has a balloon mounting part.
[0009] A balloon, which is embedded in the balloon mounting section;
[0010] When the balloon is inflated, the balloon expands and its outer edge abuts against the inner surface of the shaping rubber ring. The balloon mounting part is used to restrict the expansion of the balloon in the plane where the shaping rubber ring is located.
[0011] In some cases, the inner surface of the shaping rubber ring is an arc-shaped inner groove, and the outer edge of the balloon is embedded in the arc-shaped inner groove.
[0012] In some cases, the balloon includes an outer balloon body and a pressure portion located in the middle of the outer balloon body, the pressure end of the pressure portion protruding outward from the contact surface of the shaping rubber ring.
[0013] Furthermore, the pressure-reducing part is a pressure-reducing balloon; both the pressure-reducing balloon and the balloon's outer body are connected to the air intake.
[0014] Furthermore, the balloon is an annular balloon, the pressure-relief part is an elastic pressure column, and the pressure-relief part can be inserted through the middle of the annular balloon; the balloon is connected to the air intake part.
[0015] Furthermore, the outer body of the balloon is disc-shaped, the pressure-retaining part is a water-filled balloon, and the outer body of the balloon is connected to the air intake part.
[0016] In some cases, the shaping ring is made of silicone, and the annular balloon of the balloon has a petal-like structure and is divided into several petals along the radial direction of the balloon.
[0017] In some cases, the balloon mounting portion of the inner ring of the shaping rubber ring has a supporting base.
[0018] In some cases, the shaping rubber ring has a handle, and the air inlet is inserted into the handle.
[0019] A second aspect of this invention provides a puncture compression assembly, including any of the aforementioned puncture compression balloons; the inflation assembly is connected to the air inlet of the puncture compression balloon.
[0020] In some cases, the puncture compression balloon is also connected to a tightening strap, the length of which is adjustable.
[0021] In this disclosure, a shaping rubber ring restricts the deformation of the balloon, preventing it from flattening further during compression and thus providing better support and compression. Additionally, when the balloon mounting section has a supporting base, it better prevents the balloon from expanding only towards the puncture wound side, further enhancing the compression effect. When combined with a tightening band, it provides good compression even when the patient is standing. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings.
[0032] The first aspect of this utility model provides a puncture compression balloon, such as Figure 1 As shown, it includes:
[0033] The shaping rubber ring 110 has a ring-shaped structure, and its inner ring has a balloon mounting part.
[0034] A balloon 120 is embedded in the balloon mounting part, and a shaping rubber ring 110 is used to wrap around the balloon 120 in a ring.
[0035] When the balloon 120 is inflated, it expands, and its outer edge abuts against the inner surface of the shaping rubber ring 110. The balloon mounting portion is used to limit the expansion of the balloon 120 in the plane where the shaping rubber ring 110 is located; specifically, as follows... Figure 1 As shown, when the balloon 120 is inflated, it cannot break through the constraint of the shaping rubber ring 110. After the gas is injected, the balloon 120 will expand in the direction shown by the arrow, and this expansion direction matches the compression requirement of the puncture wound, so that the balloon 120 can better compress the wound.
[0036] Any of the features mentioned below related to puncture and compression balloons can be selected independently; their combined use is not strictly required, as long as they achieve the desired effect.
[0037] To facilitate better installation of the balloon 120, the inner surface of the shaping rubber ring 110 is an arc-shaped inner groove, and the outer edge of the balloon 120 is embedded in the arc-shaped inner groove. This allows the balloon 120 to be directly embedded within the shaping rubber ring 110, without necessarily requiring air pressure for fixation. Specifically, the outer edge of the balloon 120 can be an outward arc shape; when the two are fitted together, the outer edge of the balloon 120 and the arc-shaped inner groove achieve nesting.
[0038] The balloon and other components can be made of elastic rubber or similar materials, as long as they can achieve the functions required by this utility model.
[0039] Of course, the shaping rubber ring 110 maintains a certain degree of deformation when needed, so that when the patient is in a lying position, although the puncture site in their lower back is compressed by the balloon, it will not feel as uncomfortable as a hard material. The rubber ring can be made of rubber, plastic, etc., with silicone being the most common material.
[0040] Furthermore, regarding the compression function of the balloon 120, to enhance its compression effect, the balloon 120 includes an outer balloon body 150 and a pressure-resistant portion 140 located in the middle of the outer balloon body 150. The pressure-resistant end 141 of the pressure-resistant portion 140 protrudes beyond the contact surface of the shaping rubber ring 110 (the surface of the shaping rubber ring 110 that contacts the skin). However, in this design, the pressure-resistant portion 140 is not strictly required to be inflatable. The thickness of the outer balloon body 150 decreases from the outer end to the middle.
[0041] Regarding the pressing part 140, it can take at least the following three forms:
[0042] The first type, such as Figure 2 As shown, the pressure-relief part 140 is a pressure-relief balloon; both the pressure-relief balloon and the outer balloon body 150 (the outer balloon of balloon 120 excluding the pressure-relief balloon) are connected to the air inlet 131. That is, when inflated, both the pressure-relief balloon and the outer balloon body 150 will expand. Since the pressure-relief balloon protrudes beyond the contact surface of the shaping rubber ring 110, it can better compress the puncture wound, while the outer balloon body 150 contacts the skin around the puncture wound to provide support, preventing irregular movement of the puncture-relief balloon and resulting in pressure displacement. The outer balloon body 150 is generally slightly concave to the contact surface of the shaping rubber ring 110, but it may also protrude beyond the contact surface of the shaping rubber ring 110 when inflated to a greater extent.
[0043] The second type, such as Figure 3 , 4As shown, the balloon outer body 150 (the outer ring of the balloon 120 excluding the pressure portion 140) is an annular balloon. The pressure portion 140 is an elastic compression column, and the pressure portion 140 can pass through the middle of the balloon outer body 150. The balloon 120 is connected to the air inlet 131. Similarly, the balloon outer body 150 is generally slightly concave to or flush with the contact surface of the shaping rubber ring 110. When inflated, it may also protrude beyond the contact surface of the shaping rubber ring 110. However, the pressure portion 140 does not use inflation to compress; it can be an elastic element, such as a cylindrical spring fitted with silicone. Its pressure end 141 protrudes beyond the contact surface of the shaping rubber ring 110 to better compress the puncture wound. When the patient is lying down, although the pressure end 141 can be squeezed and deformed, it is not easy to tilt under the support of the balloon outer body 150, and can provide good support and compression. The elastic compression column can be separated from the annular balloon. The elastic compression column has protrusions at both ends. When it is inserted into the annular balloon, the protrusions at both ends can be well locked onto both sides of the annular balloon.
[0044] The third type, such as Figure 5 As shown, the outer body 150 of the balloon is disc-shaped, but its outer edge still abuts against the shaping rubber ring 110. The pressure part 140 is a water-filled balloon, and the water-filled balloon is located on one side of the outer body 150. The outer body 150 of the balloon is connected to the air inlet 131. When the outer body 150 of the balloon is inflated through the air inlet 131, the disc-shaped outer body 150 of the balloon will also expand longitudinally due to the restraint of the shaping rubber ring 110. At this time, the water-filled balloon is squeezed out so that it can better fit the wound.
[0045] Regarding the balloon exoskeleton, a flap-like shape allows for more grooves on its surface, providing better breathability when in contact with the skin and reducing the impact on the skin at the pressure point. It can also be available in three shapes:
[0046] The first type, such as Figure 4 In this design, the outer body of the balloon is divided into several petals along the radial direction of the balloon 120. This petal structure can be formed by injection molding of the balloon's spherical material, or the outer body of the balloon can be set as several independent petal-shaped air sacs. Then, ventilation holes can be set between any two adjacent petal-shaped air sacs. For details, please refer to the existing technology, which will not be elaborated here.
[0047] The second type is when the balloon exoskeleton is set as several independent valve-shaped air bladders. These multiple valve-shaped air bladders may not have an inflation function, but instead use a fixed air pressure. In this case, the balloon exoskeleton plays more of a supporting role. Only the pressure-reducing balloon can be inflated. At this time, each valve-shaped air bladder works independently and can provide support from multiple directions.
[0048] The third type, as mentioned earlier, can have a disc-shaped outer body 150 without a through-hole in the middle, such as... Figure 5In the middle, the middle part is used to set the water-filled balloon, which is a balloon filled with water.
[0049] In some instances, such as Figure 7 As shown, the balloon mounting portion of the inner ring of the shaping rubber ring 110 has a supporting base. This supporting base is located on the shaping rubber ring 110 and is connected to one side of the shaping rubber ring 110. The supporting base is used to limit the balloon's expansion to this side. This is particularly suitable when the patient is standing, as the supporting base can still limit the balloon 120, preventing it from expanding outwards and better keeping the balloon compressed towards the wound site. In use, the supporting base is generally located between the balloon 120 and the body.
[0050] The shaping rubber ring 110 has a handle 130, and the air inlet 131 passes through the handle 130. The handle 130 is designed to facilitate handling and also to protect the inflation tube 210, preventing the inflation tube of the inflation assembly 200 from being flattened when the patient is lying down, which would make it difficult to adjust the compression shape by inflating and deflating the tube while lying down.
[0051] The second aspect of this utility model provides a puncture and compression component, such as... Figure 6 As shown, the puncture compression balloon 100 includes any of the aforementioned forms; the inflation assembly 200 is connected to the air inlet 131 of the puncture compression balloon 100. Of course, to improve the usability of the assembly, the puncture compression balloon 100 and the inflation assembly 200 can be configured as a detachable structure, for example, the air inlet 131 and the tracheal connection end 211 can be connected by a plug. Furthermore, the puncture compression balloon is also connected to a tightening strap 300. Further, the tightening strap 300 and the puncture compression balloon 100 can also be detachable (e.g., Velcro fastening, attaching the puncture compression balloon 100 to the tightening strap 300), and the tightening of the tightening strap 300 can be adjusted. Regarding the adjustment of the tightening strap, existing technology can be used to adjust the tightening force according to different body types and different tightening needs.
[0052] When in use, the puncture compression device can be worn around the patient's waist via a tightening strap. The pressure of the puncture compression balloon 100 can then be adjusted via the inflation component 200. For example, more gas is generally needed when the patient is standing, while some gas may need to be released when lying down. The inflatable balloon 220 can be a balloon similar to that of a mercury sphygmomanometer. For deflation, a deflation port can be provided in the inflation component 200, such as the inflatable balloon 220. When deflation is needed, the plug can be removed; when deflation is appropriate, the port can be plugged. Of course, other conventional methods can also be used; this part is not particularly limited. Regarding the tightening strap, there are also many adjustment options. For example, it can be adjusted like a regular abdominal binder, or it can be tightened or loosened like a shoelace with a knob. Existing technology can be used for these adjustments.
[0053] In summary, this approach enhances compression by limiting balloon deformation, making it adaptable to a wider range of applications compared to current clinical practices.
[0054] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
