Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a compression hemostasis device for bleeding after anorectal disease surgery. Background Art

[0002] Postoperative bleeding is common after anorectal disease surgery. It can be divided into chronic bleeding and acute bleeding according to the severity of the bleeding. Chronic bleeding: Some patients have no obvious bleeding symptoms in the early stage, only blood during defecation, or blood dripping after defecation, blood spurting, no bleeding in the stool, abdominal distension and urgency to defecate, blood discharged from the anus during flatulence, or even when urinating, walking, or standing, blood flows out of the anus, and the amount of blood varies. Acute bleeding: The stool is full of blood or blood clots, bright red, or dark red blood clots, sometimes hundreds of milliliters can be discharged at a time. Severe cases are accompanied by unbearable abdominal distension, anal swelling, tenesmus, frequent urge to defecate, or even blood or dark red blood clots discharged from the anus while walking.

[0003] Although the incidence of postoperative bleeding after anorectal disease surgery is not high, it accounts for about 0.5-1.0% in domestic literature. However, if it is not taken seriously and not handled in time, it will also lead to serious consequences, causing hemorrhagic shock to the patient, and even endangering the patient's life in severe cases. Therefore, a postoperative bleeding compression hemostasis device for anorectal disease is proposed to solve the above problem. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a compression hemostasis device for postoperative bleeding of anorectal diseases, which has the advantages of compressing the inner wall of the intestine after anorectal disease surgery to stop bleeding and delivering hemostatic drugs into the intestine, solving the problem of massive bleeding after anorectal disease surgery. Although the incidence rate is not high, it is about 0.5-1.0% according to domestic literature. However, if it is not taken seriously and handled in time, it will also cause serious consequences, leading to hemorrhagic shock in patients, and even endangering the patient's life in severe cases.

[0006] (II) Technical solution

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A compression hemostasis device for postoperative bleeding of anorectal diseases, comprising an insertion plug, a columnar cavity extending into the interior of the insertion plug is provided at the bottom of the insertion plug, a compression drug delivery component extending to the top of the insertion plug is provided inside the columnar cavity, an airway extending to the top of the insertion plug and connected to the compression drug delivery component is provided inside the insertion plug, a pressurized air relief component connected to the airway is provided on the top of the insertion plug, a drug delivery tube connected thereto is provided on the top of the compression drug delivery component, and a drug injection component connected thereto is provided at the other end of the drug delivery tube.

[0008] The beneficial effects of the present invention are:

[0009] 1) The compression hemostasis device for postoperative bleeding of anorectal diseases opens the pressurized air-release component, pulls the compression drug delivery component to make it retract into the columnar cavity, then closes the pressurized air-release component, applies grease to the outer side of the bottom end of the insertion plug, inserts the lower end of the insertion plug into the patient's anus, and pushes the compression drug delivery component to make it slowly extend from the columnar cavity into the patient's intestine, thereby pressurizing the inside of the compression drug delivery component by pressing the pressurized air-release component until the compression drug delivery component expands to fit tightly against the inner wall of the intestine, which has the advantage of compressing and stopping bleeding on the inner wall of the intestine after anorectal disease surgery.

[0010] 2) The anorectal disease postoperative bleeding compression hemostasis device rotates the injection component to allow the hemostatic drug in the injection component to enter the compression drug delivery component through the drug delivery tube, and then flows out from the lower end of the compression drug delivery component into the patient's intestine, which has the advantage of facilitating the delivery of hemostatic drugs into the intestine.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the compression medication component includes a support spring, a cylindrical airbag, a ball head pull rod and a delivery tube, the inner cavity top wall of the columnar cavity is fixedly connected with a support spring extending to the bottom of the insertion plug, the inner cavity top wall of the columnar cavity is fixedly connected with a cylindrical airbag located on the outside of the support spring, the top of the insertion plug is slidably connected with a ball head pull rod extending below it and located on the inside of the support spring, the lower end of the cylindrical airbag is fixedly connected to the outside of the bottom end of the ball head pull rod to form a cavity connected to the airway, the ball head pull rod is provided with a delivery tube running through its upper and lower ends, the top of the ball head pull rod is fixedly connected with a drug delivery tube connected to the delivery tube, and the sliding part of the ball head pull rod and the insertion plug is sealed;

[0013] Furthermore, the pressurized deflation component includes an air guide tube, a deflation valve and a pressurized air bag. The top of the insertion plug is fixedly connected to an air guide tube connected to the airway, the other end of the air guide tube is provided with a deflation valve connected thereto, and the other end of the deflation valve is provided with a pressurized air bag connected thereto.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the air release valve is opened to connect the interior of the cylindrical airbag with the outside, and the ball head pull rod is pulled to make the cylindrical airbag on the outside of the support spring enter the inside of the support spring under the pull of the ball head pull rod, and at the same time, the support spring is contracted and elastically deformed until the cylindrical airbag is completely received into the columnar cavity, and then the air release valve is closed, grease is applied to the outside of the bottom end of the insertion plug, the lower end of the insertion plug is inserted into the patient's anus, and the ball head pull rod is pushed to make the cylindrical airbag extend from the lower end of the support spring and extend into the patient's intestine, and then the support spring restores its elastic deformation, and the pressurized airbag is pressed to pressurize the inside of the cylindrical airbag through the airway and the airway until the cylindrical airbag expands to fit closely to the inner wall of the intestine, thereby compressing the inner wall of the intestine after anorectal disease surgery to stop bleeding.

[0015] Furthermore, the drug injection assembly includes a placement shell, a 50 ml syringe, a threaded rod and a contact head. The end of the drug delivery tube away from the placement shell is fixedly connected to the placement shell, and the drug delivery tube extends to the left wall of the inner cavity of the placement shell. A 50 ml syringe connected to and adapted to the drug delivery tube is provided in the placement shell. The right side of the placement shell is threadedly connected to a threaded rod extending therein, and the left end of the threaded rod is rotatably connected to a contact head that contacts the push rod of the 50 ml syringe.

[0016] The beneficial effect of adopting the above further scheme is that by rotating the threaded rod, the force generated by the rotation of the thread drives the contact head to squeeze the 50 ml syringe, and the hemostatic drug in the 50 ml syringe is delivered to the delivery tube through the drug delivery tube, and then flows out through the ball head pull rod into the patient's intestine, making it convenient to deliver the hemostatic drug to the intestine.

[0017] Furthermore, a T-shaped tie which is symmetrically distributed front to back is fixedly connected to the outer side of the ball head portion at the upper end of the insertion plug.

[0018] The beneficial effect of adopting the above further scheme is that after the insertion plug is placed in the patient's body, the T-shaped strap is passed through the patient's crotch and the two ends of the T-shaped strap on the same side of the patient's body are tightened to fix the insertion plug and prevent the insertion plug from falling out.

[0019] Furthermore, the material of the cylindrical airbag and the ball head pull rod are both silicone rubber.

[0020] The beneficial effect of adopting the above further scheme is that the silicone rubber can still maintain a certain flexibility, resilience and surface hardness, and the mechanical properties do not change significantly. In addition, the silicone rubber is non-toxic, tasteless, odorless, does not adhere to human tissue, has an anti-coagulant effect, and has very little reactivity to body tissue.

[0039] Working principle:

[0040] The first step to implement the innovation point:

[0041] Step 1: Open the air release valve 502 to connect the inside of the cylindrical airbag 302 with the outside, pull the ball head pull rod 303 to make the cylindrical airbag 302 outside the support spring 301 enter the inside of the support spring 301 under the pull of the ball head pull rod 303, and at the same time make the support spring 301 shrink and elastically deform until the cylindrical airbag 302 is completely received in the columnar cavity 2, and then close the air release valve 502;

[0042] Step 2: Apply lubricating grease to the outer side of the bottom end of the insertion plug 1, insert the lower end of the insertion plug 1 into the patient's anus, pass the T-shaped lace 8 through the patient's crotch, and tighten the two ends of the T-shaped lace 8 on the same side of the patient's body to fix the insertion plug 1 to prevent the insertion plug 1 from falling out, push the ball head pull rod 303, so that the cylindrical airbag 302 extends from the lower end of the support spring 301 and extends into the patient's intestines, and then the support spring 301 recovers its elastic deformation;

[0043] Step 3: By pressing the pressurized balloon 503, the inside of the cylindrical balloon 302 is pressurized through the airway 501 and the airway 4 until the cylindrical balloon 302 expands to fit closely against the inner wall of the intestine, thereby compressing the inner wall of the intestine after anorectal disease surgery to stop bleeding.

[0044] The second innovation point implementation steps:

[0045] Step 1: pre-load the hemostatic drug into the 50 ml syringe 702. After the cylindrical airbag 302 is placed and pressurized, the threaded rod 703 is rotated. The force generated by the rotation of the thread drives the contact head 704 to squeeze the 50 ml syringe 702.

[0046] Step 2: The hemostatic drug in the 50 ml syringe 702 is delivered to the delivery tube 304 via the drug delivery tube 6;

[0047] Step 3: The hemostatic drug thus flows out through the ball head pull rod 303 and enters the patient's intestine, making it easier to deliver the hemostatic drug into the intestine.
