Description

Technical Field

[0001] This invention relates to the field of gastroenterology nursing technology, specifically to a simple bedside hemostasis device for upper gastrointestinal bleeding. Background Technology

[0002] In gastroenterology, upper gastrointestinal bleeding caused by ulcers, vascular malformations, tumors, or ruptured esophageal and gastric varices is a common gastroenterological emergency. The upper gastrointestinal tract includes the oral cavity, esophagus, stomach, and duodenum. Because patients with upper gastrointestinal bleeding are at risk of recurrent bleeding, the accuracy and timeliness of nursing care directly affect the patient's prognosis.

[0003] Existing treatment methods mainly include endoscopic hemostasis and drug therapy. Endoscopic hemostasis is the preferred treatment for acute upper gastrointestinal bleeding, allowing direct observation of the bleeding site and precise intervention via endoscopy. Drug therapy is usually used as an adjunct or transitional treatment when endoscopic intervention is not immediately possible. However, in routine clinical hemostasis procedures, endoscopic hemostasis is difficult to perform and often requires experienced physicians. Nurses may not be able to provide timely hemostasis care, potentially delaying the patient's condition. Therefore, this invention provides a nursing device for upper gastrointestinal bleeding that allows nurses to insert a gastric tube for hemostasis, facilitating clinical hemostasis care, reducing the bleeding rate, and improving the prognosis for patients with upper gastrointestinal bleeding. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a simple bedside hemostasis device for upper gastrointestinal bleeding, which facilitates clinical hemostasis nursing operations for nurses, reduces the bleeding rate, and improves the prognosis of patients with upper gastrointestinal bleeding.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A simple bedside hemostasis device for upper gastrointestinal bleeding, comprising a gastric tube body; the gastric tube body includes an insertion end and a delivery end, the delivery end including a central tube for aspirating and exchanging fluids and an injection tube for injecting hemostatic drugs, the injection tubes being symmetrically arranged with the central tube as the center;

[0006] The insertion end and the delivery end are detachably connected, and the insertion end is equipped with a detection mechanism for detecting the contact between the insertion end and gastric fluid.

[0007] Furthermore, the testing mechanism includes a transfer port located at the center of the insertion end, which is connected to the central tube. The end of the central tube away from the insertion end is connected to a negative pressure mechanism. The diameter of the transfer port on the side closer to the central tube is larger than the diameter on the side farther from the central tube. An activation block is fitted inside the insertion end with a clearance, and the activation block is arranged in a ring around the transfer port.

[0008] The starting block includes a counterweight block and a floating block that are fixedly connected to each other. The floating block is located above the counterweight block. When the insertion end is in contact with the gastric juice, the starting block is located in the transfer port and adjacent starting blocks abut against each other. When the insertion end is not in contact with the gastric juice, adjacent starting blocks separate.

[0009] Furthermore, a sliding groove is provided on the insertion end, which is connected to the transfer port. A slider is fitted inside the sliding groove with a gap, and the slider is fixedly connected to the starting block.

[0010] Furthermore, the injection tube is connected to the central tube, and the central tube has several through holes arranged sequentially along the length of the central tube, and the diameter of the through holes is smaller than the diameter of the transfer port.

[0011] A first contact is fixedly connected to the floating block, and a second contact is fixedly connected to the insertion end. The second contact is located inside the transfer port. The first contact and the second contact form a circuit loop. The first contact and the second contact are also electrically connected to a control panel. The control panel is electrically connected to the negative pressure mechanism.

[0012] The control panel is used to input the preset execution power, control the operation of the negative pressure mechanism based on the execution power, generate a display reminder command based on the circuit loop current generated when the first contact and the second contact are in contact, and then generate a power increase command to the negative pressure mechanism based on the circuit loop current.

[0013] Furthermore, a camera is slidably fitted inside the central tube, and the central tube, insertion end, and counterweight are made of transparent rubber layers.

[0014] Furthermore, the injection tube is connected to a transfer tube, which is located on both sides of the central tube. A first solenoid valve is connected to the connection between the injection tube and the transfer tube. The first solenoid valve is located above the float and is electrically connected to the control panel.

[0015] Furthermore, a flow rate sensor is connected inside the transfer pipe. The flow rate sensor is used to measure the real-time flow rate inside the transfer pipe and send the real-time flow rate to the control panel.

[0016] The control panel is used to compare the real-time flow rate with the set standard flow rate when executing the power increase command. If the real-time flow rate is less than the standard flow rate, a start command is sent to the first solenoid valve. If the real-time flow rate is greater than or equal to the standard flow rate, a maintain command is sent to the first solenoid valve.

[0017] Furthermore, the control panel is also used to generate a delayed intermittent command based on the start command sent by the first solenoid valve when the real-time flow rate is less than the standard flow rate, send a start-stop cycle command to the first solenoid valve based on the delayed intermittent command, and send a suction cycle command to the negative pressure mechanism based on the delayed intermittent command.

[0018] Furthermore, the control panel is also used to compare the real-time flow rate with the set safe flow rate when the negative pressure mechanism is running based on the power control. If the real-time flow rate is greater than the safe flow rate, a power reduction command is sent to the negative pressure mechanism; if the real-time flow rate is less than or equal to the safe flow rate, a maintenance command is sent to the negative pressure mechanism.

[0019] Furthermore, the end of the central tube furthest from the insertion end is connected to a storage sac.

[0020] The above approach has the following beneficial effects:

[0021] 1. This solution features a detachable connection between the insertion end and the delivery end, allowing for easy replacement of the insertion end and delivery end during use. This also facilitates the detection mechanism within the insertion end to adapt to the needs of different delivery ends, ensuring that each patient has their own tube.

[0022] 2. In this protocol, fluids such as mucus, gastric juice, and blood are aspirated from the upper respiratory tract through a central tube. This allows the hemostatic drugs delivered by the injection tube to come into contact with the wound, thereby ensuring the hemostatic effect of the drugs on the wound and reducing the amount of bleeding for the patient.

[0023] 3. In this procedure, during the insertion of the gastric tube, the nurse can directly reach the stomach through the gastric tube to stop bleeding. The delivery position of the gastric tube can be detected by a detection device to improve the safety and experience required during the insertion process. Hemostatic drugs can then be used for temporary hemostasis. This procedure is convenient for nurses to operate, reduces the bleeding rate in a timely manner, and improves the prognosis of patients with upper gastrointestinal bleeding.

[0024] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The following detailed description illustrates the specific implementation method:

[0034] Example 1:

[0035] As attached Figures 1 to 4 As shown: A simple bedside hemostasis device for upper gastrointestinal bleeding includes a gastric tube body 1; the gastric tube body 1 includes an insertion end 2 and a delivery end, the delivery end includes a central tube 11 for aspirating and exchanging fluids and an injection tube 3 for injecting hemostatic drugs. In this embodiment, the hemostatic drugs include, but are not limited to, norepinephrine-soaked saline and thrombin, etc., and the injection tubes 3 are symmetrically arranged with the central tube 11 as the center.

[0036] The end of the central tube 11 furthest from the insertion end 2 is connected to a storage sac. The gastric fluid is temporarily stored in the storage sac so that it can be reinfused after the gastric wound has been hemostatically treated. This reduces the interference of the gastric fluid with the coagulation of the wound, facilitates the coagulation of the wound, and reduces the amount of bleeding.

[0037] The insertion end 2 is detachably connected to the delivery end. The insertion end 2 is provided with a detection mechanism for detecting the contact between the insertion end 2 and gastric fluid. The detection mechanism includes a transfer port 21 located at the center of the insertion end 2. The transfer port 21 is connected to the central tube 11. The end of the central tube 11 away from the insertion end 2 is connected to a negative pressure mechanism. The negative pressure mechanism is existing technology and will not be described in detail in this embodiment. The diameter of the transfer port 21 on the side closer to the central tube 11 is larger than the diameter on the side of the transfer port 21 away from the central tube 11. The insertion end 2 is fitted with a starter block 22 with a clearance fit. The starter block 22 is arranged in a ring around the transfer port 21.

[0038] The starting block 22 includes a counterweight block and a floating block that are fixedly connected to each other. The floating block is located above the counterweight block. When the insertion end 2 is in contact with the gastric juice, the starting block 22 is located in the transfer port 21 and adjacent starting blocks 22 abut against each other. When the insertion end 2 is not in contact with the gastric juice, adjacent starting blocks 22 separate.

[0039] The injection tube 3 is connected to the central tube 11, and the central tube 11 has several through holes 12. The through holes 12 are arranged sequentially along the length of the central tube 11, and the diameter of the through holes 12 is smaller than the diameter of the transfer port 21. A first contact is fixedly connected to the float block, and a second contact is fixedly connected to the insertion end 2. The second contact is located inside the transfer port 21. The first contact and the second contact form a circuit loop. The first contact and the second contact are also electrically connected to a control panel. The control panel is located outside the gastric tube body 1 and is electrically connected to the negative pressure mechanism.

[0040] The control panel is used to input the preset execution power, control the operation of the negative pressure mechanism based on the execution power, and generate a display reminder command based on the circuit loop current generated when the first contact and the second contact are in contact. In this embodiment, the control panel is electrically connected to a display screen that displays based on the reminder command. The display screen is existing technology and will not be described in detail in this embodiment. Then, a power increase command is generated to the negative pressure mechanism based on the circuit loop current.

[0041] The specific implementation process is as follows:

[0042] This device is not suitable for patients with severe nasopharyngeal malformations, ruptured esophageal varices with bleeding, or corrosive drug poisoning, where the insertion of a gastric tube may be affected. For conscious patients, a semi-recumbent or supine position should be adopted, with the head turned to one side (to prevent aspiration). For comatose patients, the patient should be placed supine without a pillow, with the head tilted back; a mouth opener may be used to assist in opening the mouth if necessary. The gastric tube insertion length is then measured using the gastric tube, from the tip of the nose, through the earlobe, to the xiphoid process; approximately 45-55 cm for adults and 14-18 cm for children. The tip of the gastric tube should be thoroughly lubricated with lubricant for 10-15 cm to reduce insertion resistance. The gastric tube is then inserted through the nose or mouth according to the gastric tube insertion precautions. In some other embodiments, several inflatable balloons for hemostasis are fixedly connected to the delivery end, allowing for the replacement of different delivery ends as needed.

[0043] Since the insertion end 2 and the delivery end are detachably connected, the insertion end 2 and the delivery end can be replaced during use, and the detection mechanism inside the insertion end 2 can adapt to the needs of different delivery ends, so as to realize the need for one tube per patient.

[0044] During continuous aspiration via the negative pressure mechanism connected to the central tube 11, fluids such as mucus, gastric juice, and blood from the upper respiratory tract are aspirated through the central tube 11. This facilitates the contact between the hemostatic drugs delivered by the subsequent injection tube 3 and the surrounding wound. The counterweight then causes the activation block 22 to seal the central tube 11, reducing the risk of aspiration of surrounding tissues during the insertion of the gastric tube 1 and ensuring the safety of the insertion process.

[0045] When the insertion end 2 comes into contact with the gastric juice, the density of the floating block is less than that of the gastric juice, causing the floating block to carry the starting block 22 to float on the surface of the gastric juice. As the starting block 22 moves upward, the diameter difference of the transfer port 21 causes the starting block 22 to move to both sides, thus preventing the starting block 22 from sealing the central tube 11. Based on the continuous negative pressure suction within the central tube 11, the gastric juice is aspirated, allowing the nurse to determine whether the insertion end 2 has reached the stomach based on the gastric juice level displayed in the central tube 11. Temporary hemostasis is then achieved using hemostatic drugs, which is convenient for nurses to operate, promptly reduces the bleeding rate, and improves the prognosis of patients with upper gastrointestinal bleeding.

[0046] The working status of the negative pressure mechanism is controlled by the control panel. During normal operation of the negative pressure mechanism, continuous low-power suction is performed by the negative pressure mechanism. The through hole 12 on the central tube 11 is used to aspirate mucus, attachments and bleeding around the esophagus. The suction material discharged during the insertion of the gastric tube body 1 is used to determine whether bleeding has occurred around the esophagus, so that the operator (nurse) can easily identify the bleeding point.

[0047] After the gastric tube body 1 comes into contact with the gastric fluid, the circuit formed by the connection of the first and second contacts will remind the operator to stop the insertion of the gastric tube according to the reminder displayed on the control panel. This will reduce the need to confirm the insertion length during the insertion process. The power will be increased to facilitate the aspiration of the gastric fluid, which will then facilitate the subsequent application of hemostatic drugs to the stomach for hemostasis.

[0048] Example 2:

[0049] The difference from Embodiment 1 is that the insertion end 2 has a sliding groove (not shown in the figure), the sliding groove is connected to the transfer port 21, and a slider is fitted in the sliding groove with a gap. The slider is fixedly connected to the starting block 22.

[0050] The specific implementation process is as follows: the slider slides in the groove to limit the direction and position of the starting block 22 in the transfer port 21, thereby ensuring that the starting block 22 is dispersed to both sides during the movement of the transfer port 21, so that the starting block 22 no longer closes the transfer port 21.

[0051] Example 3:

[0052] The difference from Embodiment 2 is that a camera is slidably fitted inside the central tube 11, and the central tube 11, the insertion end 2, and the counterweight are made of transparent rubber layers.

[0053] The specific implementation process is as follows: The camera slides inside the central tube 11, and the transparent rubber layer of the central tube 11, the insertion end 2 and the counterweight are used to display the insertion status of the gastric tube body 1, thereby improving the accuracy of the insertion process.

[0054] Example 4:

[0055] The difference from Embodiment 3 is that, in another embodiment, the injection tube 3 is connected to a transfer tube 31, which is located on both sides of the central tube 11, and a first solenoid valve is connected at the connection between the injection tube 3 and the transfer tube 31. The first solenoid valve is located above the float and is electrically connected to the control panel.

[0056] The specific implementation process is as follows: During the process of aspirating gastric juice through the central tube 11, if the central tube 11 becomes blocked or the flow rate decreases, the transfer tube 31 is opened through the first solenoid valve, and physiological saline is injected through the injection tube 3 and discharged through the transfer tube 31. The physiological saline pushes the floating block to move away from the central tube 11 through the transfer port 21. Then, the floating of the gastric juice causes the diameter of the transfer port 21 to change and loosen, so as to reduce the possibility of blockage caused by food residue during the process of aspirating gastric juice through the central tube 11 and ensure the unobstructed flow of the central tube 11.

[0057] Example 5:

[0058] The difference from Embodiment 4 is that a flow rate sensor is connected inside the transfer pipe 31. The flow rate sensor is used to measure the real-time flow rate inside the transfer pipe 31 and send the real-time flow rate to the control panel.

[0059] The control panel is used to compare the real-time flow rate with the set standard flow rate when executing the power increase command. If the real-time flow rate is less than the standard flow rate, a start command is sent to the first solenoid valve. If the real-time flow rate is greater than or equal to the standard flow rate, a maintain command is sent to the first solenoid valve.

[0060] For example, during the process of aspirating gastric fluid from the central tube 11, the real-time flow rate is compared with the standard flow rate to determine the blockage of the central tube 11. When the real-time flow rate is less than the standard flow rate, causing blockage, the first solenoid valve is activated to discharge saline solution from the transfer tube 31 to flush the inside of the transfer port 21. At the same time, the starting block 22 inside the transfer port 21 is moved to clear the transfer port 21 and ensure the unobstructed flow of the central tube 11.

[0061] The control panel is also used to generate a delayed intermittent command based on the start command sent by the first solenoid valve when the real-time flow rate is less than the standard flow rate, send a start-stop cycle command to the first solenoid valve based on the delayed intermittent command, and send a suction cycle command to the negative pressure mechanism based on the delayed intermittent command.

[0062] For example, during the process of clearing the interior of the transfer port 21 through the transfer tube 31, the first solenoid valve and the negative pressure mechanism are repeatedly activated by delay, so that the saline solution discharged from the transfer tube 31 and the gastric juice in the central tube 11 are drawn, and the interior of the transfer port 21 is repeatedly flushed, thereby strengthening the clearing of the blockage inside the transfer port 21 and ensuring the smooth flow of the central tube 11.

[0063] Example 6:

[0064] The difference from Embodiment 5 is that the control panel is also used to compare the real-time flow rate with the set safe flow rate when the negative pressure mechanism is running based on the power control. If the real-time flow rate is greater than the safe flow rate, a power reduction command is sent to the negative pressure mechanism; if the real-time flow rate is less than or equal to the safe flow rate, a maintenance command is sent to the negative pressure mechanism.

[0065] For example, during the insertion of the gastric tube body 1, the real-time flow rate is compared with the safe flow rate to reduce the excessive negative pressure suction on the surrounding tissues generated during the movement of the gastric tube body 1, thereby reducing the risk of collision damage between the gastric tube body 1 and the surrounding tissues (such as the tracheal wall) and ensuring the safety of the gastric tube insertion.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
