The specific contents are as follows; 1. It is equipped with a hemostatic balloon and a rotating tube head. The rotating tube head can twist, coil and tighten the hemostatic balloon under the action of elastic force, so that the hemostatic balloon fits spirally on the outside of the drainage tube, thereby making the end of the hemostat smoother in the process of extending into the patient's uterine cavity.

When the hemostasis is completed and the hemostatic balloon is controlled to contract, the rotating tube head will rotate elastically and pull the movable tube to slide and reset, thereby squeezing the elastic liquid sac, so that the medicine in the elastic liquid sac is sprayed out through the drainage tube. At the same time, the rotating tube head slides while elastically rotating, so that the drainage tube can evenly spray and flush the inner wall of the uterine cavity.

[0018] A rotating tube head and an elastic scraper are provided. As the hemostatic balloon recovers and the rotating tube head rotates elastically, it can drive the elastic scraper to scrape off blood clots and body fluids attached to the inner wall of the drainage tube, thereby further improving the cleaning effect of the instrument; an observation tube is further provided, and the movable column can extend and slide under the action of hydraulic pressure to display the hydraulic pressure in the hemostatic balloon.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: When using the existing clinical intrauterine hemostatic device for obstetrics and gynecology, the capsule cannot be tightly limited, making it difficult to insert and inconvenient to display the pressure. In order to solve this technical problem, this embodiment discloses the following technical content, please refer to Figure 1-Figure 5 As shown; A clinical intrauterine hemostat for obstetrics and gynecology that is easy to clean includes a drainage tube 1 for draining blood, a filling tube 3 fixedly installed on the outside of the drainage tube 1, and a hemostatic balloon 5 fixedly connected to the right end of the filling tube 3; a drainage interface 2 fixedly connected to the left end of the drainage tube 1, an infusion connector 4 fixedly connected to the outside of the left end of the filling tube 3, and a regulating valve 6 installed on the infusion connector 4, and a pressure display mechanism for displaying the internal pressure of the hemostatic balloon 5 installed on the infusion connector 4.

[0023] The drainage tube 1 and the filling tube 3 are coaxially arranged, and the filling tube 3 is fixed on the outside of the drainage tube 1, and the infusion connector 4 injects physiological saline into the filling tube 3 and the hemostatic balloon 5 through an external infusion set. At the same time, the hemostatic balloon 5 expands and fits the bleeding area of the patient's uterine cavity after being injected with liquid.

[0024] The pressure display mechanism includes an observation tube 7 fixedly connected to the outside of the infusion connector 4, and a sealing plug 9 is slidingly connected to the inner side of the observation tube 7 in an interference fit manner, and a movable column 8 is fixedly connected to the left side of the sealing plug 9. At the same time, the movable column 8 passes through the left end of the observation tube 7 and is telescopically connected to the observation tube 7. A spring 10 is connected between the sealing plug 9 and the observation tube 7. The outer wall of the movable column 8 is provided with scale lines, and the movable column 8 can detect the pressure inside the hemostatic balloon 5 when it is telescopically adjusted in the observation tube 7.

[0025] In the initial state, the hemostatic balloon 5 remains twisted and rolled up and tightly adheres to the outside of the drainage tube 1 under the action of the rotational elastic force of the rotating tube head 13. At this time, the hemostatic balloon 5 can be extended into the patient's uterine cavity. During the extension process, the extension of the hemostatic balloon 5 can be assisted by rotation. When the hemostatic balloon 5 is extended to the bleeding position, the injector connected to the infusion connector 4 is controlled to inject physiological saline into the infusion connector 4 and the filling tube 3, so that the physiological saline enters the hemostatic balloon 5, thereby causing the hemostatic balloon 5 to expand and adhere to the bleeding position in the patient's uterine cavity, thereby applying pressure and stopping bleeding. As the hydraulic pressure inside the hemostatic balloon 5 increases, the sealing plug 9 will drive the movable column 8 to elastically expand and contract in the observation tube 7 under the action of the liquid pressure, so that the scale on the movable column 8 can monitor and display the hydraulic pressure in the hemostatic balloon 5. Subsequently, by pressing the movable column 8 back and forth, the pressure test effect of the hemostatic balloon 5 can be adjusted to achieve a kneading effect.

[0026] Example 2: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 1. The existing clinical intrauterine hemostatic device for obstetrics and gynecology is inconvenient to evenly flush and apply medicine to the bleeding area inside the uterine cavity during use, and it is inconvenient to assist in cleaning the blood stains inside the pipeline. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 2 and Figure 5-10 As shown; the right end of the drainage tube 1 is fixedly connected to the connecting tube 11, and the outer side of the connecting tube 11 is telescopically connected to the movable tube 12, and the right end of the movable tube 12 is elastically rotatably installed with a rotating tube head 13, and a tube opening 1301 is provided in the middle of the rotating tube head 13. An infusion component for conveying cleaning fluid is also provided between the connecting tube 11 and the movable tube 12, and the left end of the rotating tube head 13 is also fixedly connected to an elastic scraper 18.

[0027] The connecting tube 11 and the movable tube 12 are coaxially arranged, and the outer wall of the connecting tube 11 is evenly provided with guide grooves 1101, and the inner wall of the left end of the movable tube 12 is evenly fixed with a guide block 1201, and the guide block 1201 slides along the guide groove 1101. The hemostatic balloon 5 is sleeved on the outside of the drainage tube 1 and the movable tube 12, and the rotating tube head 13 is fixedly connected to the right end of the hemostatic balloon 5. In the initial state, the rotating tube head 13 drives the hemostatic balloon 5 to spirally twist, and during the filling process of the hemostatic balloon 5, the rotating tube head 13 is driven to rotate elastically and drive the movable tube 12 to slide to the right on the outside of the connecting tube 11. During the discharge of the hemostatic balloon 5, the rotating tube head 13 drives the hemostatic balloon 5 to twist and tighten.

[0028] The infusion assembly includes an elastic liquid bag 14 which is sleeved on the outside of the connecting tube 11, and the elastic liquid bag 14 is arranged in an annular structure, and the left and right ends of the elastic liquid bag 14 are respectively fixedly connected to the right end of the drainage tube 1 and the left end of the movable tube 12, the left end of the elastic liquid bag 14 is fixedly connected to a liquid drawing tube 15, and the right side of the elastic liquid bag 14 is evenly fixedly connected to a liquid discharge tube 17, and the right end of the liquid discharge tube 17 is evenly fixedly connected to the rotating tube head 13. At the same time, a liquid storage bottle 16 is installed on the outside of the left end of the drainage tube 1, and the left end of the liquid drawing tube 15 is located on the inner side of the liquid storage bottle 16 to realize liquid absorption. Both the liquid drawing tube 15 and the liquid discharge tube 17 are provided with a one-way valve structure, and an elastic scraper 18 is evenly fixedly installed on the left end of the rotating tube head 13, and the elastic scraper 18 is attached to the inner wall of the drainage tube 1, and the elastic scraper 18 is driven to scrape off blood clots and body fluids adhered to the inner wall of the drainage tube 1 during the elastic rotation of the rotating tube head 13.

[0029] As the hemostatic balloon 5 expands, its right end will drive the rotating tube head 13 to rotate elastically, and at the same time drive the movable tube 12 to slide on the outside of the connecting tube 11. As the movable tube 12 slides, it can stretch the elastic liquid sac 14, so that the elastic liquid sac 14 draws the medicine in the liquid storage bottle 16 through the liquid drawing tube 15. When the hemostasis is completed, the regulating valve 6 is opened to discharge the physiological saline through the infusion connector 4. At this time, the rotating tube head 13 will elastically rotate and reset to achieve the re-twisting of the hemostatic balloon 5. As the hemostatic balloon 5 twists, it will pull the movable tube 12 along the outside of the connecting tube 11. Sliding reset is performed, at this time the movable tube 12 will cooperate with the drainage tube 1 to squeeze the elastic liquid bag 14, so that the medicine inhaled in the elastic liquid bag 14 is discharged through the discharge pipe 17, and with the rotation and movement of the rotating tube head 13, the spraying effect of the medicine can be further promoted, and with the rotation of the rotating tube head 13, it can drive multiple elastic scrapers 18 to rotate synchronously, so that the elastic scrapers 18 can scrape off the blood and body fluids attached to the inner wall of the drainage tube 1, and with the twisting of the hemostatic balloon 5, it can achieve full discharge of the inner liquid, reducing the subsequent pressure of medical waste disposal.
