[0002] In the conservative medical treatment of esophageal varicose bleeding, a double-balloon gastric tube is often used to compress the gastric fundus and esophagus. However, the current double-balloon gastric tube has significant defects and poor compression effect, which cannot meet clinical treatment needs.

[0003] The main defects are: it cannot be effectively fixed. When the patient's position changes or moves, the compression balloon often becomes loose, especially the gastric fundus balloon and the gastric fundus become detached, resulting in interruption of compression. During compression, the compression intensity is adjusted by the doctor or nurse's subjective feeling, and the compression accuracy is extremely poor. If the compression intensity is too high, it will inevitably cause discomfort to the patient, and even local ischemia and necrosis. If the compression intensity is too low, local bleeding will continue, and the effect of compression hemostasis cannot be achieved.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0027] like Figure 1 and Figure 2 As shown: In order to achieve effective compression and hemostasis of the cardia and esophagus, and to adjust the compression state and improve the convenience of operation, the present invention includes a gastric tube 1 that can be inserted into the stomach through the nasal cavity, a cardia compression balloon 3 for compressing the cardia, and an esophageal compression balloon 4 for compressing the esophagus; it also includes a traction line 5 that can pull the gastric tube 1. After the gastric tube 1 is pulled by the traction line 5, the esophageal compression balloon 4 and the cardia compression balloon 3 can compress the esophagus and the cardia respectively.

[0028] Specifically, the gastric tube 1, the cardia compression sac 3, and the esophageal compression sac 4 are all made of materials that meet medical standards. The gastric tube 1 can be placed in the stomach through the nasal cavity. When the head end of the gastric tube 1 is placed in the stomach, the cardia compression sac 3 corresponds to the cardia, and the esophageal compression sac 4 is located in the esophagus. The cardia compression sac 3 is an air sac or a liquid sac, and the esophageal compression sac 4 is an air sac or a liquid sac. When the cardia compression sac 3 is in a filled state, the cardia can be compressed by the cardia compression sac 3, and when the esophageal compression sac 4 is in a filled state, the esophagus can be compressed by the esophageal compression sac 4. After compression by the cardia compression sac 3 and the esophageal compression sac 4, hemostasis can be achieved.

[0029] In order to achieve the effectiveness of compressing the cardia and esophagus and to adjust the compression state, in an embodiment of the present invention, the gastric tube 1 can be pulled by the pull wire 5, and the pulling force can be loaded on the gastric tube 1 through the pull wire 5, so that the esophageal compression balloon 4 and the cardia compression balloon 3 can compress the esophagus and the cardia respectively, and by adjusting the pulling force applied to the gastric tube 1 by the pull wire 5, the compression state of the esophageal compression balloon 4 and the cardia compression balloon 3 can be adjusted.

[0030] Furthermore, the head end of the pulling wire 5 is connected to the inner wall of the gastric tube 1, and the tail end of the pulling wire 5 is connected to a gravity traction device for applying traction;

[0031] The gravity traction device includes a gravity traction block for generating traction force and a traction pulley 16 adapted to be connected to the traction line 5 . The traction pulley 16 is connected to the traction load-bearing beam 14 through the pulley traction line 15 . The gravity traction block can be hung on the tail end of the traction line 5 .

[0032] In the embodiment of the present invention, the head end of the pulling wire 5 is fixed to the gastric tube, and the tail end of the pulling wire 5 is connected to the gravity traction device. The gravity traction block can be a weight or other object with a weight mark, which can be selected according to needs. The traction pulley 16 is a fixed pulley, and the traction load-bearing beam 14 can support the traction pulley 16. The traction pulley 16 is installed below the traction load-bearing beam 14 through the pulley pulling wire 15. When the gravity traction block is hung on the tail end of the pulling wire 5, the traction gravity of the gravity traction block acts on the gastric tube 1 through the action of the traction pulley 16. When the gastric tube 1 is pulled by the gravity traction block, the esophageal compression sac 4 and the cardia compression sac 3 in the filled state can respectively compress the esophagus and the cardia; when the weight of the gravity traction block is different, the traction force on the gastric tube 1 is different, and the compression state through the esophageal compression sac 4 and the cardia compression sac 3 can be adjusted. In addition, the gravity traction block can be hung on the tail end of the traction line 5 for a long time, that is, it can achieve the traction effect on the gastric tube 1 for a long time, so that the esophageal compression balloon 4 and the cardia compression balloon 3 can compress the esophagus and cardia for a long time, thereby improving the convenience of traction and compression.

[0033] During specific implementation, the head end of the pull wire 5 corresponds to the esophageal compression balloon 4, and the head end of the pull wire 5 is adjacent to the junction of the esophageal compression balloon 4 and the cardia compression balloon 3; a pull hook 11 is provided at the tail end of the pull wire 5; a pull positioning tube 12 is also provided on the gastric tube 1, and the tail end of the pull wire 5 can pass through the pull positioning tube 12.

[0034] In the embodiment of the present invention, the position of the pulling wire 5 in the gastric tube 1 corresponds to the esophageal compression sac 4, the esophageal compression sac 4 is wrapped on the gastric tube 1, the head end of the pulling wire 5 is adjacent to the joint of the esophageal compression sac 4 and the cardia compression sac 3, and the pulling wire 5 can be conveniently connected with the gravity traction block through the pulling hook 11. The pulling positioning tube 12 is obliquely distributed on the gastric tube 1, the head end of the pulling wire 5 is located in the gastric tube 1, and the tail end of the pulling wire 5 can be conveniently connected with the traction pulley 16 and the gravity traction block after passing through the pulling positioning tube 12.

[0035] Furthermore, a guide drainage head 2 for inserting a guide is provided at the head end of the stomach tube 1 , and the guide drainage head 2 can be connected to the stomach tube 1 .

[0036] In the embodiment of the present invention, the guide drainage head 2 is located at the head end of the stomach tube 1, and the tail end of the stomach tube 1 forms a connection joint 13, which can be connected to the drainage bag by using the connection joint 13. The guide drainage head 2 can guide the process of inserting the stomach tube 1 into the stomach, and after the stomach tube 1 is inserted in place, the guide drainage head 2 can be used to facilitate the liquid to be drained to enter the stomach tube 1 through the guide drainage head 2, and drain from the stomach tube 1 into the drainage bag, so as to achieve collection by the drainage bag.

[0037] Furthermore, the guide drainage head 2 includes an intragastric guide drainage tube 17 and a cardiac guide drainage tube 18, and the intragastric guide drainage tube 17 is connected to the gastric tube 1 through the cardiac guide drainage tube 18;

[0038] The cardiac compression balloon 3 is disposed on the cardiac guide drainage tube 18 , and the cardiac compression balloon 3 is adjacent to the esophageal compression balloon 4 on the gastric tube 1 .

[0039] In the embodiment of the present invention, the length of the guide drainage head 2 is 5 cm to 15 cm and the length of the cardiac guide drainage tube 18 is not more than 5 cm, or the length of the intragastric guide drainage tube 17 is 5 cm to 15 cm. By setting the length of the intragastric guide drainage tube 17 and the cardiac guide drainage tube 18, the entire guide drainage head 2 can be prevented from damaging the stomach and the like, and the reliability of the guide drainage head 2 during the guiding and drainage process can be improved.

[0040] like Figure 3As shown, an intragastric drainage partitioning support frame 20 is provided in the intragastric drainage guide tube 17 for partitioning the intragastric drainage guide tube 17 into a plurality of intragastric drainage cavities, and an intragastric drainage opening 21 is provided on the intragastric drainage guide tube 17;

[0041] The intragastric drainage opening 21 is distributed along the length direction of the intragastric guide drainage tube 17, and the intragastric drainage opening 21 corresponds to the intragastric drainage cavity separated by the intragastric drainage separation support frame 20; the cross-section of the intragastric drainage cavity is arc-shaped, and the intragastric drainage opening 21 occupies at least 2 / 3 of the curvature of the intragastric drainage cavity.

[0042] In the embodiment of the present invention, the intragastric drainage partition support frame 20 is in a trident shape, and the intragastric drainage partition support frame 20 is located in the intragastric guide drainage tube 17. Generally, the length of the intragastric drainage partition support frame 20 is not less than the length of the intragastric guide drainage tube 17, and the intragastric drainage partition support frame 20 is coaxially distributed with the intragastric guide drainage tube 17. In specific implementation, the intragastric guide drainage tube 17 can be divided into three intragastric drainage cavities by the intragastric drainage partition support frame 20. Of course, the intragastric drainage partition support frame 20 can also adopt other structural forms, as long as it can achieve the separation of the space in the intragastric guide drainage tube 17 to obtain the intragastric drainage cavity.

[0043] The intragastric drainage opening 21 passes through the tube wall of the intragastric guide drainage tube 17, and the length of the intragastric drainage opening 21 is not greater than the tube wall of the intragastric guide drainage tube 17. The intragastric drainage opening 21 corresponds to the intragastric drainage cavity, that is, the objects in the stomach can enter the corresponding intragastric drainage cavity through the intragastric drainage opening 21. Generally, the intragastric guide drainage tube 17 is a cylindrical tube, so the cross-section of the intragastric drainage cavity is fan-shaped. In order to improve the drainage effect, the intragastric drainage opening 21 occupies at least 2 / 3 of the curvature of the intragastric drainage cavity. The intragastric guide drainage tube 17 and the cardia guide drainage tube 18 can prevent the gastric tube 1 from sticking to the stomach wall.

[0044] like Figure 4 As shown, a cardiac drainage partition support frame 22 is provided in the cardiac guide drainage tube 18 for partitioning the cardiac guide drainage tube 18 into a plurality of cardiac drainage cavities. A plurality of cardiac drainage holes 19 are also provided on the cardiac guide drainage tube 18, and the cardiac drainage holes 19 are connected to the corresponding cardiac drainage cavities.

[0045] In the embodiment of the present invention, the cardiac drainage support partition frame 22 generally needs to adopt the same structural form as the gastric drainage partition support frame 20, that is, the cardiac drainage cavity in the cardiac guide drainage tube 18 can be connected to the gastric drainage cavity in a one-to-one correspondence, and the cardiac drainage cavity and the gastric drainage cavity are correspondingly connected to form a drainage channel. The cardiac drainage hole 19 runs through the wall of the cardiac guide drainage tube 18, and the drainage effect can be further improved through the cardiac drainage hole 19.

[0046] Furthermore, it also includes a cardiac compression balloon connecting tube 6 connected to the cardiac compression balloon 3 and an esophageal compression balloon connecting tube 10 connected to the esophageal compression balloon 4, the cardiac compression balloon connecting tube 6 is provided with a cardiac compression balloon connecting tube sealing valve 7, and the esophageal compression balloon connecting tube 10 is provided with an esophageal compression balloon connecting tube sealing valve 8.

[0047] In the embodiment of the present invention, the cardia compression sac 3 can be inflated or injected with water through the cardia compression sac connecting tube 6, and the esophageal compression sac 4 can be inflated or injected with water through the esophageal compression sac connecting tube 10. The cardia compression sac connecting tube sealing valve 7 can be used to control the process of filling and deflation of the cardia compression sac 3 or the process of injecting and draining water, and the esophageal compression sac connecting tube sealing valve 8 can be used to control the process of filling and deflation of the esophageal compression sac 4, and the specific use and working process of the cardia compression sac connecting tube sealing valve 7 and the esophageal compression sac connecting tube sealing valve 8 are well known to those skilled in the art and will not be described in detail here. In specific implementation, the cardia compression sac 3 includes a sac portion symmetrically distributed on the cardia guide drainage tube 18, and the sac portion is disc-shaped when in a filled state, and the shape of the cardia compression sac 3 can be used to compress the cardia.

[0048] Furthermore, it also includes a compression pressure detection device for measuring the compression pressure of the cardia compression balloon 3 and / or the compression pressure of the esophagus compression balloon 4.

[0049] In the embodiment of the present invention, the compression pressure detection device can detect the compression pressure of the cardia compression bag 3 and the compression pressure of the esophagus compression bag 4. Figure 1 and Figure 2 In the figure, an esophageal compression pressure detector 9 installed on the esophageal compression balloon connecting tube 10 is shown. The esophageal compression pressure detector 9 can detect the compression pressure of the esophageal compression balloon 4. The esophageal compression pressure detector 9 can be implemented by a pressure sensor, etc. Of course, other structural forms can also be used. The specific selection can be made according to needs, which will not be repeated here. The compression pressure of the cardia compression balloon 3 can also be implemented in the same detection method.

[0050] In specific implementation, the head end of the pulling wire 5 can be set at the end of the cardia drainage support partition frame 22 close to the esophageal compression sac 4. By connecting the pulling wire 5 to the cardia drainage support partition frame 22, the action point of the pulling wire 5 can be located at the center of the gastric tube 1. When the pulling wire 5 is connected to the gravity traction block, the entire gastric tube 1 can be evenly stressed. When the gastric tube 1 is stressed by the pulling wire 5, the esophageal compression sac 4 in a filled state can compress the esophagus under the pulling action, and then drive the cardia compression sac 3 to compress the cardia. The compression pressure can be detected by the compression pressure detection device, and the compression state can be adjusted according to the result of the compression pressure detection.

[0051] like Figure 5 As shown, the cardiac compression sac 3 and the esophageal compression sac 4 are interconnected, and also include a water injection and inflation connecting pipe 23 for injecting water or inflating air into the cardiac compression sac 3 and the esophageal compression sac 4. A water injection and inflation sealing valve 24 for controlling the water injection state and the inflation state is arranged on the water injection and inflation connecting pipe 23.

[0052] In the embodiment of the present invention, when the cardia compression sac 3 and the esophageal compression sac 4 are air sacs, gas can be injected into the cardia compression sac 3 and the esophageal compression sac 4 through the water injection and inflation connecting tube 23; when the cardia compression sac 3 and the esophageal compression sac 4 are liquid sacs, liquid can be injected into the cardia compression sac 3 and the esophageal compression sac 4 through the water injection and inflation connecting tube 23. After the cardia compression sac 3 and the esophageal compression sac 4 are connected, the pressure in the cardia compression sac 3 is the same as the pressure in the esophageal compression sac 4. The water injection and inflation sealing valve 24 is located at the end of the water injection and inflation connecting tube 23. The water injection and inflation sealing valve 24 can be used to control the state of inflation or water injection. The specific function of the water injection and inflation sealing valve 24 can refer to the description of the cardia compression sac connecting tube sealing valve 7 and the esophageal compression sac connecting tube sealing valve 8, which will not be repeated here. In addition, an esophageal compression pressure detector 9 can also be set on the water injection and air inflation tube 23.

[0053] During specific use, it is connected to the drainage bag through the connecting joint 13, and the cardiac compression effect can be judged by the drainage status of the drainage bag. If a large amount of blood continues to flow into the drainage bag after the compression begins, it means that the compression pressure of the cardiac compression bag 3 is insufficient, and the pulling weight of the pulling hook 11 can be increased to increase the compression pressure of the cardiac compression bag 3. After the pressure is increased, if no blood flows out or the drained blood gradually decreases, it means that the current compression effect of the cardiac compression bag 3 is good.

[0054] The esophageal compression situation can be judged by the patient's vomiting of blood in the mouth. If there is still a lot of blood in the mouth after the compression begins, it means that the compression pressure of the esophageal compression bag 4 is insufficient. The compression pressure of the esophageal compression bag 4 can be increased by increasing the pulling weight of the pulling hook 11.

[0055] When the cardiac compression bag 3 and the esophageal compression bag 4 are interconnected, if it is judged through the drainage bag and the vomiting blood in the mouth that the cardiac compression and / or esophageal compression pressure is insufficient, the air pressure or liquid pressure in the cardiac compression bag 3 and the esophageal compression bag 4 can be increased, or the pulling weight of the pulling hook 11 can be increased to increase the compression pressure and improve the compression effect.
