Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an anal compression hemostasis and drug delivery device. Background Technology

[0002] An anal compression hemostatic drug delivery device is a medical device that integrates hemostasis and drug delivery functions. It is usually used to treat bleeding in the anal and rectal areas and may be combined with local drug treatment. It is usually made of soft and durable materials, such as silicone or rubber, to ensure patient comfort and safety. The device may be designed as a balloon or other shapes to facilitate insertion into the anus and close contact with the bleeding site. The balloon is designed to apply pressure by inflating or injecting liquid to achieve hemostasis.

[0003] A search revealed that Chinese patent CN110743093A discloses an anal compression hemostasis drug delivery device. The main body consists of an upper drug delivery section and a lower fixing section. The lower fixing section is connected to a fixing mechanism. The lower fixing section is designed to fit the human body. The upper drug delivery section has a drug delivery component. The fixing mechanism includes an upper fixing strap and a lower fixing strap, both with adhesive attachments. The cooperation between the upper and lower fixing straps ensures the stability of the anal compression hemostasis drug delivery device. The drug delivery component includes a drug delivery tube. The upper drug delivery section has a drug delivery port that mates with the drug delivery tube. A drug delivery element is fixedly connected to the outside of the upper drug delivery section. The drug delivery element is introduced through the inlet and directly contacts the anal mucosa, facilitating direct contact and absorption of the drug. An exhaust pipe is parallel to the drug delivery tube to ensure pressure balance during drug delivery. However, the above technical solution still has the following shortcomings in use: The anal compression hemostasis drug delivery device directly inserts the drug delivery body into the anus. Although this method is technically direct and effective, in practice, the direct insertion process is often accompanied by pain and discomfort for patients. This not only increases the psychological burden on patients but may also affect their willingness to cooperate with treatment. In some cases, severe pain may even trigger resistance from patients. Secondly, this "one-size-fits-all" design ignores the differences in anal anatomy among different patients. Everyone's anus size, shape, and sensitivity are different, and existing drug delivery bodies often lack sufficient adjustability to be personalized according to the specific situation of the patient. This means that in some cases, the drug delivery body may be too large or too small, which not only reduces the effectiveness of treatment but may also aggravate the patient's pain and even cause unnecessary damage to the anal tissue.

[0004] Therefore, this application provides an anal compression hemostasis drug delivery device to achieve the purpose of rapid compression hemostasis and drug delivery. Summary of the Invention

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 8 As shown, an anal compression hemostasis and drug delivery device includes a support plate 1, a positioning cloth 16 on the bottom surface of the support plate 1, positioning posts 17 fixedly installed at the four corners of the bottom surface of the support plate 1, and adhesive layers 18 on both ends of the top surface of the positioning cloth 16; a sealing cylinder 2, which is disposed through the top surface of the support plate 1 and fixedly connected to the through point; a connecting rod 3, which is fixedly installed at the top of the sealing cylinder 2; an adjusting mechanism disposed on the outer wall of the connecting rod 3; a threaded seat 5, which is fixedly fitted onto the bottom outer wall of the sealing cylinder 2; a nut 6, which is threadedly fitted onto the outer wall of the threaded seat 5; and an expansion bladder 7. The following components are fixedly installed on the top surface of the nut 6: a hemostatic sponge layer 8, which is disposed on the outer wall of the expansion bladder 7; a clearance port 9, which is opened on the outer wall of the hemostatic sponge layer 8; a plurality of drug delivery ports 10, which are arranged in a linear array on the inner wall of the clearance port 9; a drug delivery tube 11, which is disposed through the outer wall of the expansion bladder 7, and the end of the drug delivery tube 11 is connected to the plurality of drug delivery ports 10; a gas guiding assembly, which is disposed on the sealing cylinder 2; a connecting assembly, which is disposed on the bottom surface of the support plate 1; a cover plate 14, which is fixedly installed at the bottom opening of the sealing cylinder 2; and a prompting assembly, which is disposed on the cover plate 14. Before using the entire device, the length of the device needs to be adjusted according to the patient's condition using the adjustment mechanism. After adjustment, the expansion balloon 7 corresponding to the device length can be installed on the threaded seat 5 via the nut 6. At this time, the expansion balloon 7 can be located on the outer wall of the sealing cylinder 2, connecting rod 3, and adjustment mechanism. Then, the device can be inserted into the patient's anus. During insertion, the expansion balloon 7 is in an uninflated state, ensuring easier insertion and avoiding additional pain for the patient. After insertion, the positioning cloth 16 can be installed on the bottom surface of the support plate 1 and positioned with the positioning post 17 through the opening. Then, the adhesive... The layer 18 is fixed by being bonded to the patient's buttocks. Then, the expansion balloon 7 can be inflated by the air delivery component to expand the expansion balloon 7 to fit the patient's usage. During the expansion of the expansion balloon 7, the indicator component can display the expansion status of the expansion balloon 7 so that the air delivery can be stopped in time to ensure greater patient comfort. After the expansion balloon 7 is expanded, the hemostatic sponge layer 8 can be used to compress and stop bleeding inside the patient's anus. At the same time, the medication can be injected into the anus through the drug delivery tube 11. When the device is inserted, the relief port 9 can be aligned with the medication application position so that the medication can be directly delivered through the drug delivery port 10.

[0025] like Figure 3 , Figure 4 As shown, the adjustment mechanism includes: an adjustment cap 41, which is slidably fitted onto the top of the connecting rod 3, and the top of the adjustment cap 41 is set as a semi-circle; a guide groove 42, which is formed on the outer wall of the connecting rod 3; a plurality of slots 43, which are arranged in a linear array on the outer wall of the connecting rod 3, and one end of the slots 43 is connected to the guide groove 42, and the inner side wall of the slots 43 is provided with anti-slip texture; and a locking block 44, which is fixedly installed on the inner side wall of the adjustment cap 41, and the locking block 44 is slidably connected to the guide groove 42. When adjusting the length of the device, the adjusting cap 41 can be rotated so that the locking block 44 slides from the locking groove 43 into the guide groove 42. This will pull the adjusting cap 41 and change the overall length of the adjusting cap 41 and the connecting rod 3. After the adjustment is completed, the adjusting cap 41 can be reversed so that the locking block 44 slides into the corresponding locking groove 43, thus completing the adjustment of the device length.

[0026] like Figure 3 , Figure 5 , Figure 6As shown, the air guiding assembly includes: an air guiding bag 121, disposed on the inner wall of the sealing cylinder 2; several conduits 122, arranged in a ring array on the top outer wall of the air guiding bag 121, with both ends of the conduits 122 communicating with the top surfaces of the air guiding bag 121 and the sealing cylinder 2 respectively; a rotating disk 123, movably fitted onto the outer wall of the sealing cylinder 2 located below the support plate 1, with openings on the bottom surface of the positioning cloth 16 corresponding to the positioning post 17 and the rotating disk 123; a rotating ring 124, rotatably mounted on the inner top wall of the rotating disk 123; and two arc-shaped grooves 125, symmetrically opened. Located on the bottom surface of the rotating ring 124; two guide rods 126 are slidably installed on the inner side walls of the two arc-shaped grooves 125 respectively; two push rods 127 are symmetrically installed through the outer side wall of the sealing cylinder 2, the push rods 127 are slidably connected to the through-hole, and one end of the push rods 127 is fixedly connected to the guide rods 126; two push plates 128 are fixedly installed on the inner side of the two push rods 127 respectively, the push plates 128 are arc-shaped, the bottom end of the push plate 128 is flush with the bottom surface of the air guide bag 121, and the top end of the push plate 128 is at least lower than the bottom end of the guide tube 122. After inserting the adjusting cap 41, connecting rod 3, and the upper part of the sealing cylinder 2 into the patient's anus, the rotating disk 123 can be rotated, thereby driving the rotating ring 124 to rotate synchronously. When the rotating ring 124 rotates, it can drive the arc-shaped groove 125 to rotate. The guide rod 126 slides in the arc-shaped groove 125, and at the same time, the push rod 127 is slidably connected to the sealing cylinder 2. Therefore, when the arc-shaped groove 125 rotates, it can drive the push rod 127 to slide along the penetration point with the sealing cylinder 2, thereby causing the two push plates 128 to slide in opposite directions towards each other, which can guide the air. When the air bag 121 is squeezed, the gas in the air bag 121 enters the expansion bag 7 through the conduit 122, which inflates the expansion bag 7 and presses it against the patient's anus to stop bleeding. After use, the rotating plate 123 can be reversed. At this time, the two push plates 128 can move away from each other and separate from the air bag 121. Under the action of anal compression, the gas in the expansion bag 7 can enter the air bag 121 through the conduit 122, and the device can be easily pulled out.

[0027] like Figure 3 , Figure 7As shown, the connecting assembly includes: a support sleeve 131, fixedly installed on the bottom surface of the support plate 1; a torsion spring 132, fitted onto the outer wall of the sealing cylinder 2, with both ends of the torsion spring 132 fixedly connected to the rotating disk 123 and the support plate 1 respectively; a limiting groove 133, formed on the bottom surface of the support sleeve 131; a limiting plate 134, fixedly installed on the top surface of the rotating disk 123, with the limiting plate 134 slidably connected to the limiting groove 133, both the limiting groove 133 and the limiting plate 134 being arc-shaped to fit the support sleeve 131; several spline grooves 135, arranged in a circular array on the bottom surface of the support sleeve 131, with the spline grooves 135 communicating with the limiting grooves 133; and three splines 136, arranged in a circular array and fixedly installed on the outer wall of the limiting plate 134, the splines 136 being made of rubber material. When rotating the rotating disk 123, the rotating disk 123 can first be pulled to move the spline 136 out of the spline groove 135, so that the rotating disk 123 can be rotated. At this time, the limiting plate 134 can rotate synchronously in the limiting groove 133. After the rotation is completed, the rotating disk 123 can be released. Under the pulling force of the torsion spring 132, the limiting plate 134 can be further inserted into the limiting groove 133, and the spline 136 can be inserted into the corresponding spline groove 135 to limit the rotating disk 123, ensuring that the push plate 128 can stably press the air bag 121.

[0028] like Figure 6 , Figure 8 As shown, the prompting component includes: a port 151, which is opened on the bottom surface of the cover plate 14; a connecting pipe 152, which is disposed on the bottom surface of the air-conducting bag 121 and is connected to the air-conducting bag 121; a telescopic pipe 153, which is fixedly installed at the bottom end of the connecting pipe 152 and is located inside the port 151; a sealing plate 154, which is fixedly installed at the bottom end of the telescopic pipe 153 and the diameter of the sealing plate 154 is at least larger than the diameter of the port 151; two retaining rings 155, which are fixedly fitted onto the outer wall of the bottom end of the telescopic pipe 153; and two retaining grooves 156, which are opened on the inner wall of the port 151 at positions corresponding to the two retaining rings 155. During the inflation of the expansion bladder 7, in the initial state, the retaining ring 155 is engaged in the second retaining groove 156, and gas can be injected into the expansion bladder 7. When the gas in the expansion bladder 7 is inflated to fit the anus, the air guide bag 121 is squeezed, and the gas can enter the telescopic tube 153 through the connecting tube 152, pushing the telescopic tube 153 open and extending. At this time, the retaining ring 155 can disengage from the second retaining groove 156, and the sealing plate 154 and the telescopic tube 153 extend out of the opening 151. When the staff observes this situation, they can stop rotating the rotating disk 123 to stop the inflation.
