Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a perianal compression device. Background Technology

[0002] Perianal surgery is one of the most common routine surgical procedures in the operating room. The most common perianal surgeries include anal fissures, perianal abscesses, anal fistulas, and internal and external hemorrhoids. Due to the special nature of the perianal surgical site, postoperative perianal compression devices are required for hemostasis. However, existing perianal compression devices cannot precisely apply pressure to the surgical site, resulting in poor hemostasis. Therefore, there is a need to achieve precise pressure on the surgical site.

[0003] In existing technologies, such as the utility model CN202723920U anal pressure T-belt, the patented technology uses a thickened elastic band with ventilation holes to tighten and apply pressure. However, the anal surgery site is quite special, and the thickened elastic band of this patent cannot accurately compress the surgical site, resulting in poor hemostasis due to compression.

[0004] Therefore, how to achieve precise compression of the surgical site is a problem that urgently needs to be solved in this technical field. Utility Model Content

[0005] To address the shortcomings of existing perianal compression devices that cannot accurately compress the surgical site, resulting in poor hemostasis, this invention provides a perianal compression device that positions the surgical site around the patient's anus, limits the movement of the compression mechanism by connecting it to a waist belt, and then enhances the pressure exerted on the surgical site by a pressurizing mechanism, thus achieving precise compression of the surgical site.

[0018] An airbag is disposed within the cavity, and one end of the airbag is connected to an air supply tube.

[0019] A pressure ball, connected to the other end of the air supply tube, is used to inject gas into the air bladder, so that after the air bladder inflates, it pushes the compression block to apply pressure to the patient's perianal surgical site.

[0020] As a preferred embodiment, the airbag is configured as an arc-shaped airbag.

[0021] As a preferred embodiment, a vent valve is also provided between the pressurization ball and the gas filling pipe, the vent valve being used to release the gas inside the airbag.

[0041] Examples, such as Figures 1-6 As shown,

[0042] A perianal compression device includes a waist belt 1, to which a connecting strap 2 is detachably connected, the connecting strap 2 being used to pass between the patient's legs, and further includes:

[0043] Compression mechanism 3, which is connected to the connecting belt 2, is used to compress the perianal surgical site of the patient;

[0044] Tourniquet 4, which is detachably connected to the connecting strap 2, is provided to wrap around the compression mechanism 3, and is used to abut against the patient's perianal surgical site;

[0045] A pressure boosting mechanism 5 is disposed between the connecting belt 2 and the compression mechanism 3. The pressure boosting mechanism 5 is used to increase the pressure of the compression mechanism 3 on the surgical site of the patient's perianal area.

[0046] After perianal surgery, a waist belt 1 is fastened around the patient's hips. The waist belt 1 consists of a belt body 11 and a buckle 12. The buckle 12 is fixedly connected to one end of the belt body 11, while the other end of the belt body 11 is detachably connected to the buckle 12. Through the cooperation of the buckle 12 and the belt body 11, the waist belt 1 can be adapted to fit the hips of different patients. After fastening the waist belt 1 around the patient's hips, the compression mechanism 3 is placed at the surgical site around the anus, so that the tourniquet 4 is against the surgical site. Then, the connecting strap 2 is passed between the patient's legs and connected to the waist belt 1. The compression mechanism 3 is then placed at the surgical site around the anus, so that the tourniquet 4 is against the surgical site. Next, the connecting strap 2 is passed between the patient's legs and connected to the waist belt 1. The connection of belt 1 limits the movement of the compression mechanism 3, preventing it from moving. Then, the pressure boosting mechanism 5 pushes the compression mechanism 3 to increase the pressure on the surgical site of the patient's perianal area, thereby achieving the effect of compression hemostasis. In this technical solution, after the compression mechanism 3 is positioned at the surgical site of the patient's perianal area, the connection of belt 2 and belt 1 limits the movement of the compression mechanism 3. Then, the pressure boosting mechanism 5 increases the pressure of the compression mechanism 3 on the surgical site of the patient's perianal area, achieving precise compression of the surgical site.

[0047] As a preferred embodiment, the compression mechanism 3 includes:

[0048] A connecting cloth 31 is fixedly connected to the connecting strip 2 around its perimeter, and a cavity is formed between the connecting cloth 31 and the connecting strip 2. The pressurizing mechanism 5 is disposed in the cavity.

[0049] Multiple compression blocks 32 are provided, the bottom end of which is fixedly connected to the connecting cloth 31. The multiple compression blocks 32 are hinged end to end. A compression plate 33 is integrally provided at the top of each compression block 32. The compression plate 33 is used to compress the tourniquet 4 against the patient's perianal surgical site.

[0050] The perianal area has a certain curvature. Only when the compression mechanism 3 fits snugly against the perianal area can the surgical site be accurately compressed. Therefore, multiple compression blocks 32 are connected to the connecting cloth 31. The connecting cloth 31 restricts the position of the multiple compression blocks 32 on the connecting belt 2. The multiple compression blocks 32 are hinged end to end, so that the multiple compression blocks 32 can be deflected and fit snugly against the patient's perianal area. The pressurizing mechanism 5 located in the cavity pushes the compression blocks 32, so that the compression plate 33 integrally set on the compression block 32 presses the tourniquet 4 against the patient's perianal surgical site, thereby achieving precise compression of the surgical site. Moreover, after the compression block 32 fits snugly against the perianal area, it will not affect the patient's lying or sitting position.

[0051] As a preferred embodiment, the connecting cloth 31 is configured as an elastic connecting cloth. By configuring the connecting cloth 31 as an elastic connecting cloth, the elastic connecting cloth has tensile elasticity, allowing the multiple compression blocks 32 to deflect at a greater angle on the elastic connecting cloth, and the pressurizing mechanism 5 to push within the elastic connecting cloth with a greater stroke, further increasing the pressure applied by the compression mechanism 3 to the patient's perianal surgical site.

[0052] As a preferred embodiment, the plurality of pressing blocks 32 are hinged end to end as follows:

[0053] The first end of the pressing block 32 is provided with an arc-shaped slot 34, and the tail end of the pressing block 32 is integrally provided with a connecting plate 35. The connecting plate 35 is integrally provided with a hinge rod 36, and the hinge rod 36 of the pressing block 32 passes through the arc-shaped slot 34 of the adjacent pressing block 32.

[0054] By inserting the hinge rod 36 into the arc-shaped groove 34 of the adjacent compression block 32, the movement position of the two adjacent compression blocks 32 is limited. When the compression block 32 deflects, the hinge rod 36 deflects within the arc-shaped groove 34. After deflecting to the maximum angle, the connecting plate 35 abuts against the groove wall of the arc-shaped groove 34, so that the two adjacent compression blocks 32 only deflect within a small range. After the multiple compression blocks 32 deflect within a small range, they fit and conform to the patient's perianal area.

[0055] As a preferred embodiment, the pressurization mechanism 5 includes:

[0056] An airbag 51 is disposed in the cavity, and one end of the airbag 51 is connected to an air supply tube 52.

[0057] The pressure ball 53 is connected to the other end of the air supply tube 52. The pressure ball 53 is used to inject gas into the air bag 51, so that after the air bag 51 inflates, it pushes the compression block 32 to apply pressure to the patient's perianal surgical site.

[0058] After connecting the connecting strap 2 to the waist belt 1, the connection between the connecting strap 2 and the waist belt 1 limits the multiple compression blocks 32 to the perianal surgical site of the patient. When pressure is applied to the multiple compression blocks 32, the pressure ball 53 is squeezed repeatedly. The pressure ball 53 injects gas into the air bladder 51 through the air inlet tube 52, causing the air bladder 51 to inflate. The connecting strap 2 connected to the waist belt 1 restricts the movement of one end of the air bladder 51. The other end of the air bladder 51 inflates and pushes the multiple compression blocks 32, so that the compression plate 33 integrally set on the compression block 32 compresses the tourniquet 4 and comes into close contact with the perianal surgical site of the patient.

[0059] In a preferred embodiment, the airbag 51 is configured as an arc-shaped airbag. The arc-shaped airbag can fit and conform to the multiple pressure blocks 32 arranged in an arc around the patient's anus, ensuring stable and effective pushing of the multiple pressure blocks 32 arranged in an arc.

[0060] As a preferred embodiment, a vent valve 54 is also provided between the pressurizing ball 53 and the gas filling pipe 52, and the vent valve 54 is used to release the gas in the airbag 51.

[0061] If too much gas is injected into the airbag 51, the pressure plate 33 will compress the tourniquet 4 excessively, causing discomfort to the patient. Therefore, a vent valve 54 is installed between the pressure ball 53 and the air tube 52. When too much gas is injected into the airbag 51, the gas in the airbag 51 is released through the vent valve 54, thereby adjusting the intensity of the pressure and improving the patient's comfort.

[0062] In a preferred embodiment, the tourniquet 4 and the connecting strap 2 are detachably connected in the following manner:

[0063] The bottom ends of the tourniquet 4 are fixedly connected to the rough surfaces of two Velcro straps I37 on both sides, and the connecting strap 2 is fixedly connected to the hook surfaces of two Velcro straps I37. The hook surfaces of the two Velcro straps I37 are located on both sides of the compression mechanism 3, and the tourniquet 4 and the connecting strap 2 are bonded together by the Velcro straps I37.

[0064] Tourniquet 4 needs to be replaced during patient use to prevent infection at the perianal surgical site. Therefore, the rough side of Velcro I37 is fixedly connected to both sides of the bottom end of tourniquet 4, and the hook side of Velcro I37 is fixedly connected to the connecting strap 2. When replacing tourniquet 4, the rough side of Velcro I37 on the tourniquet to be replaced is separated from the hook side of Velcro I37, and then the new tourniquet 4 is glued to the connecting strap 2 through Velcro I37, thereby realizing the quick replacement of tourniquet 4.

[0065] As a preferred embodiment, the connecting strap 2 is detachably connected to the waist belt 1 in the following manner:

[0066] A pocket 13 is threaded onto the waist belt 1, and a loop 14 is connected to the pocket 13. The tail of the connecting strap 2 is connected to the hook and loop sides of Velcro II 21. The tail of the connecting strap 2 is connected to the loop 14 via Velcro II 21. A tie 22 is fixedly connected to the head of the connecting strap 2, and the tie 22 is connected to the waist belt 1.

[0067] The connecting strap 2 is attached to the waist belt 1. The connecting strap 2 needs to be adjustable to suit different patients to ensure that the compression mechanism 3 can be placed at the surgical site around the anus. Therefore, a connecting sleeve 13 is threaded onto the waist belt 1. After the waist belt 1 is tied around the patient's hip, the sleeve 13 can slide along the waist belt 1, thereby adjusting the buckle 14 to the middle of the back of the waist belt 1. The end of the connecting strap 2 is connected to the buckle 14 via Velcro II 21, which allows the height of the compression mechanism 3 to be adjusted. By adjusting the adhesive position of Velcro II 21 at the end of the connecting strap 2, the height of the compression mechanism 3 can be adjusted so that the compression mechanism 3 corresponds to the surgical site around the anus. Finally, the connection between the strap 22 and the waist belt 1 limits the placement of the compression mechanism 3 at the surgical site around the anus.

[0068] In a preferred embodiment, the connection between the strap 22 and the waist belt 1 is as follows:

[0069] The belt 1 has a plurality of symmetrical connecting holes 15. The strap 22 is inserted through the connecting holes 15. The strap 22 is connected to the hook side and the loop side of the Velcro Ⅲ 23. The strap 22 is connected to the connecting holes 15 through the Velcro Ⅲ 23.

[0070] When connecting the tie 22 to the waist belt 1, the tie 22 is inserted into the connecting hole 15 and pulled out to a suitable length from the connecting hole 15 so that the compression mechanism 3 fits tightly against the patient's perianal area. Then, the tie 22 is bent and fixed by Velcro Ⅲ 23, thereby achieving a quick connection between the tie 22 and the waist belt 1, and at the same time limiting the position of the compression mechanism 3 in the perianal area.

[0071] The above description is merely a preferred embodiment of the utility model and is not intended to limit the technical solution of the utility model. For those skilled in the art, the utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the technical solution of the utility model should be included within the protection scope of the utility model.
