Abstract
Description
Technical Field
[0001] The present application relates to the field of medical devices, and in particular to a hemostatic ring capsule. Background Art
[0002] During the operation, it is necessary to make an incision on the patient's limb. Before treating the incision, hemostasis and exsanguination must be performed to stop the bleeding at the wound. Among the existing methods for exsanguination and hemostasis, some use a band ring, which is made of a hard material and causes great pain to the surgical patient during use, and the risk of pressure sores is extremely high; some use a rubber balloon, which is made of a thick material and becomes harder as the thickness increases, which also causes pain to the surgical patient and the risk of pressure sores; manual crushing exsanguination has a poor exsanguination effect and requires manual labor, increasing the workload of doctors; some use a gel air nozzle, which requires two layers of film to sandwich and fix the viscous soft gel in the middle during the production process to achieve the effect of sealing the gas. The gel air nozzle is difficult to sterilize, which increases the sterilization cost and risk. Utility Model Content

[0033] The following is combined with Figure 1-3 This application is described in further detail.
[0034] The embodiment of the present application discloses a blood-removing and hemostatic ring capsule.
[0035] like Figure 1As shown, the hemostatic ring bag includes a bag body 1, which is annular in shape and has a filling port. The bag body 1 is used to be mounted on the bleeding path of the patient. When in use, the bag body 1 is filled with a gas medium to prop up the annular bag body 1 to achieve the effect of rolling hemostasis and to exert a continuous hemostatic effect at the rolling end position; an air nozzle 2, the number of the filling ports is two, the two filling ports are oppositely distributed, the air nozzle 2 is arranged at the filling port, one end of the air nozzle 2 is fixedly connected to the inner wall of the bag body 1, and an inflation hole channel for inserting an air supply needle is provided in the center of the air nozzle 2.
[0036] The annular capsule is placed on the bleeding path of the patient, and the gas medium is filled into the annular capsule 1 from the air nozzle 2 using an air needle, so that the annular capsule 1 is propped up, and the inflated annular capsule compresses the bleeding path, thereby cutting off the blood from reaching the blood vessels at the bleeding point, achieving the effect of hemostasis. After the annular capsule 1 is propped up, the physician can roll the capsule 1 along the bleeding path away from the bleeding location, thereby achieving the effect of expelling blood. The inflated annular capsule 1 can apply pressure on the one hand, and on the other hand, it can reduce the pain caused to the surgical patient by the expelling blood and stopping bleeding process by expanding the pressure application area. The two filling ports correspond to two oppositely distributed air nozzles, thereby ensuring that there is always one air nozzle facing outward after the rolling stops, which is convenient for reinserting the air needle, replenishing gas or exhausting gas.
[0037] like Figure 2 and Figure 3 As shown, in order to guide the air needle to be inserted from the filling port into the bladder 1, the air nozzle 2 can be constructed in a cylindrical or truncated cone shape. In this embodiment, the air nozzle 2 is constructed in a cylindrical shape, and the cylindrical air nozzle 2 can cover the air needle to prevent the air needle from damaging the bladder 1 during the insertion process.
[0038] like Figure 2 and Figure 3 As shown, since the air needle will leave pores on the air nozzle 2 in the process of penetrating the air nozzle 2 to reach the inside of the bladder 1, in order to automatically close the pores to avoid air leakage after the air needle is pulled out after inflation, the material of the air nozzle 2 can be silicone or other biocompatible glue as the material of the air nozzle. In this embodiment, the material of the air nozzle 2 is silicone. A tightening hoop 3 is provided on the periphery of the air nozzle 2, and the tightening hoop 3 can be provided in the middle section of the air nozzle 2 or at one end close to the surface of the bladder 1. Silicone is a highly active adsorption material. After the air needle is pulled out of the air nozzle 2, the air nozzle 2 can automatically close the pores by relying on its own adsorption and the contraction force provided by the tightening hoop 3. In particular, when the double-mouth air needle is pulled out after inflation, there is very little air leakage at the pores, which can ensure that the pressure loss is extremely small, which is of great significance to the operation, ensures the hemostatic effect, and reduces the risk of surgical bleeding.
[0039] At the same time, the silica gel can be bonded to the inner wall of the capsule 1 by bonding, and the connection with the capsule 1 can be completed in one process. Compared with the use of the gel air nozzle 2 in the related art, the process is reduced and the production efficiency is improved.
[0040] like Figure 1 As shown, the balloon 1 is made of a soft film material. The soft film as the material of the balloon 1 can make the balloon 1 elastic and transparent. The inflation state of the elastic balloon 1 can be adjusted by the amount of gas medium filled in, and the inflation state is determined according to the wound depth, wound diameter or bleeding path. The transparent balloon 1 can facilitate the doctor to observe the limb tissue behind the balloon to judge the blood circulation, whether there is blood accumulation in the area covered by the balloon 1, or whether there is a pressure sore.
[0041] Since the hemostatic ring capsule needs to be disinfected before use, the disinfection generally adopts the cyclohexane sterilization method. In order to ensure air tightness and smooth sterilization process, the material of the capsule body 1 adopts polyurethane film. The polyurethane film is connected into a ring capsule shape by high-frequency heat sealing or ultrasound, gluing, etc. It is soft and light in weight, which can reduce the pain brought to the patient in the process of expelling blood and stopping bleeding, and reduce the occurrence of pressure sores. At the same time, polyurethane and silicone materials can resist the penetration of ethylene oxide used in the cyclohexane sterilization method, solving the problem of ethylene oxide residue in the cyclohexane sterilization method.
[0042] like Figure 2 and Figure 3 As shown, a pressure detection structure is provided at the inner wall of the capsule 1, and the pressure detection structure includes a patch pressure sensor 4 and a protective film 5. The protective film 5 is attached to the inner wall of the capsule 1 and the material of the protective film 5 is the same as that of the capsule 1. In this embodiment, the material of the protective film 5 is a polyurethane film, and the patch pressure sensor 4 is provided between the protective film 5 and the inner wall of the capsule 1. Through the detection result of the patch pressure sensor 4, the physician can intuitively understand the hemostatic pressure of the capsule 1, and the physician can control the amount of gas medium filled accordingly to achieve the best hemostatic effect, on the one hand to avoid secondary damage caused by excessive pressure, and on the other hand to avoid part of the blood not being cut off during the exsanguination process due to too low pressure, so as to come to the bleeding point along the bleeding path, affecting the physician's operation.
[0043] In order to facilitate the application of medicine to the wound and reduce the secondary damage to the affected part caused by the application of medicine, the outer part of the capsule 1 can be covered with an elastic hemostatic gauze (not shown in the figure), and the elastic hemostatic gauze has a similar structure and shape to the capsule 1. The doctor can spray or soak the relevant hemostatic, analgesic or anti-infective drugs on a part of the elastic hemostatic gauze, and after completing the wound treatment, the capsule 1 can be directly rolled to the wound so that the elastic hemostatic gauze covers the wound.
[0044] The implementation principle of the hemostatic annular capsule of the embodiment of the present application is as follows: the capsule body 1 is placed on the bleeding path of the patient, and the gas medium is filled into the annular capsule body 1 from the gas nozzle 2 by using an air needle, so as to prop up the annular capsule body 1. During the inflation process, the patch pressure sensor 4 can be connected to the signal of the reading device, so as to control the amount of the gas medium filled according to the detection result of the patch pressure sensor 4 to achieve the best hemostatic effect.
[0045] After the annular capsule 1 is inflated, the physician can roll the capsule 1 along the bleeding path away from the bleeding location, thereby achieving the effect of expelling blood.
[0046] After completing the exsanguination, the doctor begins to treat the wound. The doctor can set hemostatic, analgesic or anti-infection related drugs on a partial area of the elastic hemostatic gauze by spraying or infiltration. After completing the wound treatment, the capsule 1 can be directly rolled to the wound so that the elastic hemostatic gauze covers the wound.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
