Description

Technical Field

[0001] This invention relates to the field of suction devices, specifically a suction device for respiratory and critical care medicine. Background Technology

[0002] In the field of respiratory and critical care medicine, poor sputum expectoration is a major contributing factor to respiratory tract infections, ventilation dysfunction, and even respiratory failure in patients. Timely and effective sputum suction is a key nursing measure to maintain airway patency. In respiratory and critical care nursing, the direct removal of the suction catheter during sputum suction is prone to damaging the oral cavity or airway lining, which is an urgent problem to be solved.

[0003] Most existing suction devices use a direct suction design, where the tip of the suction tube experiences rigid friction against the mucosa during the suction process. This not only increases patient discomfort but may also cause complications such as mucosal bleeding and laryngospasm. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a suction device for respiratory and critical care medicine. In order to solve the aforementioned problems, this invention proposes a suction device for respiratory and critical care medicine, which solves the problem that the tip of the existing suction tube causes rigid friction with the mucosa during the extraction process, which not only increases patient pain but may also cause complications such as mucosal bleeding and laryngospasm.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a sputum suction device for respiratory and critical care medicine, including a push-pull plate and an opening assembly, wherein a manual sputum suction device is embedded in the front end of the push-pull plate, the output end of the manual sputum suction device is connected to a suction tube, a connecting hose is fixedly connected to the front end of the suction tube, and a conical tube is fixedly connected to the front end of the connecting hose. The conical tube is wound with a spirally arranged shape memory alloy wire inside, and the shape memory alloy wire passes through the connecting tube and extends to the middle of the suction tube. A temperature heater is installed in the middle of the suction tube wall, and the output end of the temperature heater is electrically connected to one end of the shape memory alloy wire. The push-pull plate has symmetrically formed sliding grooves on its two outer walls. An adjustment component for adjusting the length of the suction tube is provided at the outer end of the push-pull plate. The adjustment component includes a sliding frame that is slidably sleeved on the outer end of the push-pull plate. A connecting block is fixedly connected to the top and bottom of the sliding frame. A slider that is locked in the sliding groove is fixedly connected to the upper and lower ends of the inner wall of the sliding frame. A return spring is fixedly connected between the slider and the sliding groove. A pull wire that passes through and is slidably locked into the tapered tube is fixedly connected to the outer wall of the connecting block. An inclined bracket is symmetrically fixedly installed at the front end of the push-pull plate. Rollers with a groove diameter that matches the outer diameter of the pull wire are rotatably connected between the brackets.

[0006] Specifically, a connecting pipe is installed on the wall of the suction tube near the push-pull plate, a cleaning component is provided at the top of the push-pull plate, the cleaning component includes a water tank, a water pump, and a water outlet pipe, a sputum storage container is provided at the bottom of the push-pull plate, and a drain pipe is provided at one end of the sputum storage container, with the drain pipe and the water outlet pipe respectively connected to the suction tube.

[0007] Specifically, the suction tube and the conical tube are harder than the connecting tube and are both made of either rubber or silicone.

[0008] Specifically, the filaments are slidably engaged within the suction tube and connecting tubing and fixedly connected to the inner end of the conical tube.

[0009] Specifically, handles are fixedly connected to both outer walls of the sliding frame.

[0010] Specifically, the opening assembly includes a connecting cylinder that is bolted to the front end of the manual suction device. One end of the connecting cylinder is threadedly connected to a threaded sleeve. Both the upper and lower ends of the threaded sleeve are fixedly connected to a telescopic rod. An oral cavity opener is provided at the top and bottom ends of the telescopic rod.

[0011] Specifically, an opening is provided at the other end of the connecting cylinder.

[0012] The beneficial effects of this invention are: (1) The sputum suction device for respiratory and critical care medicine described in this invention can shrink the diameter of the conical tube as needed by using a memory alloy wire and a temperature heater. When withdrawing, the tube diameter is reduced to avoid the conical tube directly scraping the inner wall of the oral cavity, thus reducing the risk of mucosal damage. The wire pulling and sliding frame in the adjustment component can be linked to retract the conical tube into the suction tube, which not only prevents sputum from flowing out when withdrawing, but also strengthens the anti-damage effect through the double shrinkage structure. (2) The sputum suction device for respiratory and critical care medicine described in this invention has a detachable oral cavity expander that adjusts the opening degree through a threaded sleeve and a telescopic rod, which can stably open the patient's oral cavity, provide a clear operating view, and is easy to disassemble, clean and disinfect, thereby improving the convenience and safety of sputum suction operation.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: A sputum suction device for respiratory and critical care medicine includes a push-pull plate 1 and an opening assembly 510. A manual sputum suction device 11 is embedded at the front end of the push-pull plate 1. The output end of the manual sputum suction device 11 is connected to a suction tube 12. A connecting hose 13 is fixedly connected to the front end of the suction tube 12. A tapered tube 14 is fixedly connected to the front end of the connecting hose 13. A connecting tube 120 is installed on the tube wall of the suction tube 12 near the push-pull plate 1. A cleaning assembly 3 is provided at the top of the push-pull plate 1. The cleaning assembly 3 includes a water tank, a water pump, and a water outlet pipe. A sputum storage container 4 is provided at the bottom of the push-pull plate 1. A drain pipe is provided at one end of the sputum storage container 4. The drain pipe and the water outlet pipe are respectively connected to the suction tube 12.

[0018] When using the device, first lift the push-pull plate 1, then start the water pump in the cleaning assembly 3. Water from the water tank enters the suction tube 12 through the outlet pipe and connecting pipe 120 to pre-flush the suction tube 12, ensuring the tubing is clear and free of debris. Next, operate the manual suction device 11, pushing and pulling its piston rod to create a vacuum in the vacuum cylinder. This negative pressure is transmitted through the suction tube 12 and connecting hose 13 to the conical tube 14. Position the conical tube 14 towards the area where suctioning is needed. The sputum is drawn into the suction tube 12 under negative pressure, then passes through the connecting pipe 120 and the drain pipe into the sputum collection container 4 for collection. After suctioning, restart the cleaning assembly 3 to flush the suction tube 12. Finally, turn off the water pump and remove the sputum collection container 4 for cleaning and disinfection.

[0019] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a shape memory alloy wire 16 arranged in a spiral shape is wound inside the tapered tube 14, and the shape memory alloy wire 16 passes through the connecting tube 13 and extends to the middle of the suction tube 12. A temperature heater 15 is installed in the middle of the tube wall of the suction tube 12, and the output end of the temperature heater 15 is electrically connected to one end of the shape memory alloy wire 16.

[0020] The push-pull plate 1 has symmetrically formed grooves 101 on its two outer walls. An adjustment assembly 210 for adjusting the length of the suction tube 12 is provided at the outer end of the push-pull plate 1. The adjustment assembly 210 includes a sliding frame 2 that is slidably fitted onto the outer end of the push-pull plate 1. Connecting blocks 21 are fixedly connected to the top and bottom ends of the sliding frame 2. Slider blocks 23, which are locked within the grooves 101, are fixedly connected to the upper and lower ends of the inner wall of the sliding frame 2. Return springs 110 are fixedly connected between the sliders 23 and the grooves 101. Pull wires 24, which penetrate and slide into the conical tube 14, are fixedly connected to the outer walls of the connecting blocks 21. Inclined brackets 17 are symmetrically fixedly installed at the front end of the push-pull plate 1. The brackets 17 are rotatably connected to each other. Rollers 18 with groove diameters matching the outer diameter of the wire 24 are connected. The hardness of the suction tube 12 and the conical tube 14 is greater than that of the connecting hose 13, and both are made of rubber or silicone. The wire 24 is slidably engaged in the suction tube 12 and the connecting hose 13 and fixedly connected to the inner end of the conical tube 14. Handles 22 are fixedly connected to both outer walls of the sliding frame 2. Pulling the handles 22 moves the sliding frame 2. The sliding frame 2 compresses the return spring 110 through the slider 23. The rubber or silicone material can greatly reduce damage to the patient's oral cavity. The wire 24 can slide along the suction tube 12 and the connecting hose 13 to pull the conical tube 14 into the suction tube 12.

[0021] When in use, after suctioning is finished, first pull the sliding frame 2 by holding the handles 22 on both sides of the sliding frame 2. The slider 23 on the inner wall of the sliding frame 2 will slide in the slide groove 101 and compress the return spring 110. At this time, the connecting block 21 drives the pull wire 24 to move. The pull wire 24 slides along the suction tube 12 and the connecting hose 13, thereby pulling the conical tube 14 into the suction tube 12, so that the conical tube 14 is retracted into the suction tube 12, thereby reducing the diameter of the front end of the suction tube 12. When the suction tube 12 needs to be withdrawn after suctioning, since the conical tube 14 has been retracted into the suction tube 12, the conical tube 14 at the front end of the suction tube 12 is prevented from directly contacting the inner wall of the patient's oral cavity, thus preventing direct withdrawal from causing greater damage to the patient's oral cavity. When the conical tube 14 is inserted into the suction tube 12, its internal channel will be blocked, thereby preventing residual sputum from flowing out when withdrawn. The temperature heater 15 is activated, and its output end is connected to the shape memory alloy wire 16 to heat the shape memory alloy wire 16. The shape memory alloy wire 16 is spirally wound inside the conical tube 14 and extends through the connecting tube 13 to the middle of the suction tube 12. When heated, it contracts, thereby reducing the diameter of the conical tube 14 and the tip of the suction tube 12, further reducing damage to the patient's oral cavity during removal. After suctioning, the temperature heater 15 is turned off, the shape memory alloy wire 16 cools and returns to its original shape, and the diameter of the suction tube 12 returns to normal. The two work together to greatly reduce the harm to the patient's oral cavity caused by directly removing the suction tube 12.

[0022] Example 3: The technical solution of this example, which differs from that of Example 2, includes: the opening component 510 includes a connecting cylinder 5 that is bolted to the front end of the manual suction device 11. One end of the connecting cylinder 5 is threadedly connected to a threaded sleeve 51. The upper and lower ends of the threaded sleeve 51 are fixedly connected to telescopic rods 52. The top and bottom ends of the telescopic rods 52 are provided with oral cavity openers 53. The other end of the connecting cylinder 5 has an opening 501. The opening 501 can avoid affecting the setting of the wire puller 24, the water outlet pipe, and the liquid outlet pipe.

[0023] When in use, if the patient's mouth is difficult to open naturally, first rotate the threaded sleeve 51, which will be fixed on the connecting tube 5. Then press the oral retractor 53 to lock it onto the patient's upper and lower teeth, providing a clear view and sufficient operating space for suctioning. After suctioning, first remove the oral retractor 53 from the patient's mouth, then unscrew the threaded sleeve 51, remove the connecting tube 5, and clean and disinfect the retractor assembly 510 for the next use.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
