Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a flushing and fixing device for medical suction drainage tubes. Background Technology

[0002] Clinical suctioning is a key nursing procedure in medical settings for patients who are unable to expectorate sputum independently. Its core purpose is to remove sputum, secretions, and foreign objects from the patient's airway through external force, maintain airway patency, prevent complications such as suffocation, lung infection, and atelectasis caused by sputum blockage, ensure stable respiratory function, and provide basic support for treatment and rehabilitation.

[0003] The existing clinical sputum suction system mainly consists of a negative pressure suction device, a suction tube, a drainage tube, and a sputum collection container. After the negative pressure suction device is activated, it generates negative pressure, which is conducted to the suction tube through the sputum collection container and the drainage tube. Medical staff insert the suction tube into the patient's airway to a specified depth. Under the action of negative pressure, the sputum passes through the suction tube and the drainage tube in sequence and is finally aspirated into the sputum collection container for storage. After a single suction is completed, in order to prevent residual sputum from solidifying and blocking the drainage tube, medical staff need to first remove the used suction tube from the drainage tube, and then insert the end of the drainage tube into a cup of clean water. The negative pressure is used to draw in saline solution to flush the inner wall of the drainage tube, awaiting subsequent standardized treatment.

[0004] Currently, after completing suctioning and flushing, medical staff must immediately connect a new sterile suction catheter to the end of the drainage tube to prevent the inner wall of the drainage tube from being exposed to air and coming into contact with dust and microbial contaminants, thus avoiding the risk of cross-infection. To achieve temporary fixation and suspension of the drainage tube, the common clinical method is to wrap the packaging bag containing the new suction catheter around the metal frame of the negative pressure suction device. The packaging bag helps the drainage tube hang naturally next to the frame, ensuring that the drainage tube is suspended and that the inner wall does not come into contact with the outside. Since medical staff must first flush the tube and clean away any residual saline and sputum inside before connecting and fixing the new suction catheter, the entire process requires multiple adjustments to hand movements and tube positions. The steps are cumbersome and time-consuming, especially in emergency suctioning scenarios, which may delay nursing efficiency and increase the workload of medical staff. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a flushing and fixing device for medical suction drainage tubes to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flushing and fixing device for a medical suction drainage tube, comprising a liquid controller, a liquid passage tube fixedly installed inside the liquid controller, a fixing head and a first connecting head respectively provided at both ends of the liquid passage tube, a push plate installed inside the liquid controller, four sets of springs fixed at the bottom of the push plate, a liquid stop block provided at the top of the push plate, four sets of connecting columns fixed at the top of the push plate, a pressing plate installed at the end of the connecting columns, a connecting tube connected to one end of the liquid passage tube, a second connecting head and a puncture device respectively provided at both ends of the connecting tube, and an infusion bag connected to the end of the puncture device.

[0007] By adopting the above technical solution, the cumbersome operation of flushing and fixing traditional drainage tubes is solved. After the medical staff completes the suctioning operation, they remove the suction tube connected to one end of the drainage tube and insert the other end of the drainage tube into the fixing head on one side of the liquid dispensing device. Then, the medical staff can press the liquid dispensing device and the pressing plate, so that the pressing plate moves closer to the liquid dispensing device. The liquid stop block inside the liquid dispensing device releases the pressure on the inside of the infusion tube, allowing the liquid inside the infusion bag to flow into the drainage tube through the connecting tube and the infusion tube. This method simplifies the fixing and flushing operation of the drainage tube, thereby reducing the workload of medical staff.

[0008] The present invention is further provided that the top and bottom of the infusion bag are provided with rubber stoppers, and the rubber stoppers penetrate into the interior of the infusion bag.

[0009] Preferably, the needle tip of the syringe and the tip of the puncture device can be inserted into the infusion bag through a rubber stopper, thereby realizing the drainage and replenishment of the fluid inside the infusion bag.

[0010] The present invention is further provided that a hanging ring is fixed to the top of the infusion bag.

[0011] Preferably, after the entire device is assembled and installed, medical staff can hang the entire device on the infusion stand using the hanging ring on the top of the infusion bag.

[0012] The present invention is further configured such that the top of the puncture device is provided with an exhaust hole, the outer wall of the puncture device is provided with a vent pipe, the inside of the vent pipe is provided with an air inlet hole, and the air inlet hole and the exhaust hole are interconnected.

[0013] Preferably, when the liquid inside the infusion bag flows out from the connecting tube, the air pressure inside the infusion bag will decrease, and the vent hole inside the puncture device will circulate with the outside air through the vent tube, thereby solving the problem that the pressure inside the infusion bag will change due to the discharge of liquid.

[0014] The present invention is further configured such that a sealer is connected to one side of the vent pipe, and a sealing column is provided inside the sealer.

[0015] Preferably, if the device is not used for an extended period of time, medical staff can use a sealer to seal the vent tube.

[0016] The present invention is further configured such that the spring is always in a compressed state, and the liquid controller has a sliding groove inside.

[0017] Preferably, when the pressing plate is pushed without external pressure, the compressed spring pushes the pressing plate upward, causing the liquid stop block to compress the liquid passage tube and thus prevent the liquid inside the liquid passage tube from flowing.

[0018] The present invention is further configured such that the fixing head is tapered, and the outer wall of the fixing head is provided with multiple sets of retaining sleeves.

[0019] Preferably, when one end of the drainage tube is completely fitted onto the fixing head, the annular ferrule on the fixing head can seal the gap between the fixing head and the inner wall of the drainage tube, thereby preventing the inside of the drainage tube from being in contact with the external environment for a long time.

[0020] The present invention is further configured such that a fluid passage hole is provided at the top of the puncture device, and the fluid passage hole is connected to the connecting pipe at the bottom of the puncture device.

[0021] Preferably, the liquid inside the infusion bag flows through the infusion hole on the puncture device into the connecting tube connected to the end of the puncture device.

[0022] In summary, the present invention has the following main advantages: 1. This utility model solves the problem of cumbersome flushing and fixing operations of traditional drainage tubes by setting up a liquid controller, connecting tube, puncture device, and infusion bag. After the medical staff completes the sputum suction operation, they remove the sputum suction tube connected to one end of the drainage tube and insert one end of the drainage tube into the fixing head fitted on one side of the liquid controller. Then, the medical staff can press the liquid controller and the pressing plate, so that the pressing plate moves closer to the liquid controller. The liquid stop block inside the liquid controller releases the compression on the inside of the infusion tube, allowing the liquid inside the infusion bag to flow into the drainage tube through the connecting tube and the infusion tube. This method simplifies the fixing and flushing operations of the drainage tube, thereby reducing the workload of medical staff.

[0023] 2. This utility model, by setting up an infusion bag, a hanging ring, and a rubber stopper, allows the infusion bag to be hung on an infusion stand above the hospital bed via the hanging ring fixed at its top. When the drainage tube is connected to the fixed head, the entire device can fix the drainage tube. Furthermore, personnel can use an infusion needle to replenish the fluid inside the infusion bag through the rubber stopper at the top of the infusion bag, enabling the entire device to be used multiple times.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Please see Figure 1 — Figure 6The system includes a liquid control device 1, with a liquid passage tube 2 fixedly installed inside the liquid control device 1. A fixing head 201 and a first connecting head 203 are respectively installed at both ends of the liquid passage tube 2. A push plate 104 is installed inside the liquid control device 1. Four sets of springs 106 are fixed to the bottom of the push plate 104. A stop block 105 is installed at the top of the push plate 104. Four sets of connecting posts 103 are fixed to the top of the push plate 104. A pressing plate 102 is installed at the end of each connecting post 103. A connecting pipe 3 is connected to one end of the liquid passage tube 2. A second connecting head 301 and a puncture device 302 are respectively installed at both ends of the connecting pipe 3. An infusion device 302 is connected to the end of the puncture device 302. Bag 5 solves the problem of cumbersome flushing and fixing operations of traditional drainage tubes. After medical staff complete the suctioning operation, they remove the suction tube connected to one end of the drainage tube and insert one end of the drainage tube into the fixing head 201 on one side of the liquid controller 1. Then, medical staff can press the liquid controller 1 and the pressing plate 102, so that the pressing plate 102 moves closer to the liquid controller 1. The liquid stop block 105 inside the liquid controller 1 releases the compression on the inside of the liquid infusion tube 2, so that the liquid inside the infusion bag 5 flows into the drainage tube through the connecting tube 3 and the liquid infusion tube 2. This method simplifies the fixing and flushing operations of the drainage tube, thereby reducing the workload of medical staff.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 Both the top and bottom of the infusion bag 5 are provided with rubber stoppers 501, and the rubber stoppers 501 penetrate into the interior of the infusion bag 5. Personnel can insert the needle part of the needle tube and the tip of the puncture device 302 into the interior of the infusion bag 5 through the rubber stoppers 501, thereby realizing the drainage and replenishment of the liquid inside the infusion bag 5.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The top of the infusion bag 5 is fixed with a hanging ring 502. After the entire device is assembled and installed, medical staff can hang the entire device on the infusion stand through the hanging ring 502 on the top of the infusion bag 5.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The top of the puncture device 302 is provided with an exhaust port 305, and the outer wall of the puncture device 302 is provided with a vent tube 303. The vent tube 303 is provided with an air inlet 304, and the air inlet 304 and the exhaust port 305 are connected to each other. When the liquid inside the infusion bag 5 flows out from the connecting tube 3, the air pressure inside the infusion bag 5 will decrease. The exhaust port 305 inside the puncture device 302 circulates with the outside air through the vent tube 303, thereby solving the problem that the pressure inside the infusion bag 5 will change due to the discharge of liquid.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4A sealer 4 is connected to one side of the vent tube 303. The sealer 4 has a sealing column 401 inside. If the equipment is not used for a long time, medical staff can use the sealer 4 to seal the vent tube 303.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The spring 106 is always in a compressed state. The liquid controller 1 has a sliding groove 101 inside. When there is no external pressure to push the pressing plate 102, the compressed spring 106 pushes the pushing plate 104 upward, so that the liquid stop block 105 squeezes the liquid passage pipe 2 to produce compression deformation, thereby preventing the liquid inside the liquid passage pipe 2 from flowing.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The fixing head 201 is tapered, and the outer wall of the fixing head 201 is provided with multiple sets of retaining sleeves 202. When one end of the drainage tube is completely fitted onto the fixing head 201, the annular retaining sleeves 202 on the fixing head 201 can seal the gap between the fixing head 201 and the inner wall of the drainage tube, thereby preventing the inside of the drainage tube from being in contact with the external environment for a long time.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The top of the puncture device 302 is provided with a liquid passage hole 306, which is connected to the connecting tube 3 at the bottom of the puncture device 302. The liquid inside the infusion bag 5 flows into the connecting tube 3 connected to the end of the puncture device 302 through the liquid passage hole 306 on the puncture device 302.

[0036] In practical operation, medical staff insert the puncture device 302, which is connected to one end of the connecting tube 3, into the infusion bag 5 through the rubber stopper 501 at the bottom of the infusion bag 5. Then, the connecting tube 3 is threaded to the first connector 203, which is fixedly connected to one end of the liquid controller 1, through the second connector 301 at one end, thereby completing the overall assembly and installation of the flushing and fixing device. Then, the infusion bag 5 is hung on the infusion stand through the hanging ring 502 at the top. After the medical staff completes the suctioning procedure, they remove the suction tube from the end of the drainage tube and insert one end of the drainage tube into the fixing head 201 fixedly connected to one side of the liquid dispensing device 1. This prevents the end of the drainage tube from falling to the ground. Furthermore, due to the conical design of the fixing head 201, multiple sets of annular retaining sleeves 202 are provided on the outer wall of the fixing head 201, making the connection between the fixing head 201 and the drainage tube more secure. When one end of the drainage tube is completely fitted onto the fixing head 201, the annular retaining sleeves 202 on the fixing head 201 can seal the gap between the fixing head 201 and the inner wall of the drainage tube, thereby preventing the inside of the drainage tube from being in contact with the external environment for a long time. After the installation and connection between the fixing head 201 and the drainage tube are completed, medical staff can press the pressing plate 102 towards the liquid controller 1 with their fingers. This causes the pressing plate 102 to move the push plate 104 towards the bottom of the liquid controller through the four sets of connecting columns 103 fixedly connected to one side. This releases the pressure block 105 on the top of the push plate 104 from the compression and blockage of the liquid passage tube 2 inside the liquid controller 1. The water inside the infusion bag 5 flows into the drainage tube through the connecting tube 3 and the liquid passage tube 2, thus completing the flushing operation of the drainage tube. After the flushing operation of the drainage tube is completed, the medical staff release the pressing plate 102. The spring 106, which is in a compressed state, pushes the pressure block 105 back to its original position through the push plate 104. This causes the pressure block 105 to compress and deform the liquid passage tube 2, preventing the liquid in the liquid passage tube 2 from flowing.
