Description

Technical Field

[0001] This utility model relates to the field of sputum suction technology, and more specifically, to a sputum suction device for severe respiratory illnesses. Background Technology

[0002] Maintaining a clear airway is crucial in the treatment of critically ill respiratory patients, making suctioning a key nursing procedure. While existing suction devices can perform basic suctioning functions, they have several drawbacks.

[0003] On the one hand, the residual gas inside the suction device after sputum suction contains a large number of bacteria. If it is not promptly and properly discharged or sealed, this gas will accumulate inside the device, creating a breeding ground for bacteria. Due to the unreasonable gas discharge design of existing devices, the discharge process is cumbersome and difficult to completely expel the gas, allowing bacteria to multiply rapidly. This not only reduces the hygiene level of the device but also poses a serious threat to the patient's health, easily leading to complications such as secondary respiratory infections during subsequent use, hindering the patient's recovery process, and affecting the treatment effect.

[0004] On the other hand, some suction devices lack effective filtration measures, failing to filter bacteria and impurities during gas discharge. This results in contaminated gas being directly released into the surrounding environment, increasing the risk of cross-infection and posing potential harm to the health of medical staff and other patients. Furthermore, some suction devices suffer from unscientific overall structural designs, inconvenient operation, and poor stability, impacting the work efficiency of medical staff and the accuracy of suctioning procedures. Therefore, developing a respiratory critical care suction device with efficient gas discharge, good filtration performance, ease of operation, and structural stability is urgently needed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a respiratory critical care suction device, which aims to improve the problem of unreasonable gas emission design in existing devices.

[0006] This invention is implemented as follows: A respiratory critical care suction device includes a collection tank, a sealing cap threaded onto the top of the collection tank, an inlet pipe and an outlet pipe symmetrically fixedly installed on the top of the sealing cap, a suction tube sleeved onto the top of the inlet pipe, an elastic telescopic rod fixedly installed at the center of the top of the sealing cap, a first pressure plate rotatably installed at the output end of the elastic telescopic rod, sealing plates matching the inlet pipe and the outlet pipe fixedly installed at both ends of the first pressure plate, a second pressure plate fixedly installed on one side of the first pressure plate, a filter assembly matching the outlet pipe installed at one end of the second pressure plate, and an air pump cooperating with the filter assembly installed at the top of the collection tank.

[0007] In a preferred embodiment of this utility model, positioning rods are symmetrically fixedly installed on the top of the sealing cover, and positioning holes matching the positioning rods are provided on the first pressure plate and the second pressure plate. The positioning rods are symmetrically arranged on both sides of the elastic telescopic rod.

[0008] In a preferred embodiment of this utility model, a sealing plug is fixedly installed at the bottom end of the sealing plate, and the sealing plug is slidably connected to the inner wall of the liquid inlet pipe and the gas outlet pipe.

[0009] In a preferred embodiment of this utility model, the elastic telescopic rod includes a sleeve rod, a first spring, and a pull rod. The sleeve rod is fixedly installed at the top of the sealing cover, and the pull rod is slidably sleeved at the top of the sleeve rod. One end of the pull rod is fixedly installed between the sleeve rod and one side of the inner wall of the sleeve rod, and the other end of the pull rod is rotatably installed with the first pressure plate. The length of the first pressure plate is less than the length of the liquid inlet pipe and the air outlet pipe.

[0010] In a preferred embodiment of this utility model, a first slider is symmetrically fixedly installed at the bottom outer side of the pull rod, and a first groove matching the first slider is provided on the inner wall of the sleeve rod, and the first slider is slidably connected to the inner wall of the first groove.

[0011] In a preferred embodiment of this utility model, the filter assembly includes a support ring, a threaded sleeve, and a first filter screen. The support ring is fixedly installed at one end of the second pressure plate, and the threaded sleeve is threadedly installed at the top end of the support ring. The first filter screen is fixedly installed on the inner wall of the threaded sleeve. The support ring is slidably sleeved on the top end of the air outlet pipe. Two first filter screens are installed on the inner wall of the threaded sleeve, and a gap is provided between the two first filter screens.

[0012] In a preferred embodiment of this utility model, a first vertical plate is fixedly installed on one side of the top of the sealing cover. A four-sided groove is provided at the top of the first vertical plate. A four-sided prism is slidably installed on the inner wall of the four-sided groove. A second spring is fixedly installed between the bottom end of the four-sided prism and the bottom end of the inner wall of the four-sided groove. An L-shaped bracket is fixedly installed at the top of the four-sided prism. A ring is fixedly installed at one end of the bracket. The air pump is fixedly installed on the inner wall of the ring. A sealing ring is fixedly installed at the suction end of the air pump. The bottom end of the sealing ring is slidably sleeved on the threaded sleeve. The air pump is located directly above the air outlet pipe.

[0013] In a preferred embodiment of this utility model, a second slider is fixedly installed at the bottom outer side of the quadrangular prism, and a second groove matching the second slider is provided on the inner wall of the quadrangular groove.

[0014] The beneficial effects of this utility model are:

[0015] Efficient gas extraction inhibits bacterial growth: Equipped with an air pump and outlet tube, the device quickly extracts residual gas from the collection container after suctioning once the air pump is activated. This efficient gas extraction method significantly reduces the residence time of gas within the device, fundamentally disrupting the environment for bacterial growth, effectively inhibiting bacterial reproduction, significantly improving the hygiene of the device, providing greater safety for patients, and reducing the risk of secondary respiratory infections.

[0016] Multiple filtration ensures environmental and patient safety: The filter assembly includes a support ring, threaded sleeve, and a double-layered first filter with a gap between the two layers. During gas emission, this structure performs multiple filtrations, effectively intercepting bacteria and impurities. This avoids pollution of the surrounding environment by emitted gases, reduces the risk of cross-infection, and prevents bacteria from flowing back into the collection tank, further ensuring the cleanliness of the device's interior and comprehensively protecting the health and safety of patients and medical staff.

[0017] Excellent sealing prevents gas leakage: The sealing cap and collection tank are threaded together, and the sealing plug at the bottom of the sealing plate slides securely against the inner walls of the inlet and outlet pipes. This tight sealing design effectively prevents gas leakage during the emission process, ensuring that gas can only be discharged through the filter assembly, avoiding the spread of bacteria with leaked gas, and improving the safety and reliability of the device.

[0018] The structure is reasonable, and the operation is convenient and stable: The sealing cap has symmetrically arranged positioning rods at the top, and the first and second pressure plates have matching positioning holes. The elastic telescopic rod, the first spring, and the pull rod work together, with the pull rod slidingly connected to the first groove on the inner wall of the sleeve rod via a first slider. These structural designs make the operation of the first and second pressure plates more convenient and stable, allowing medical staff to accurately control the opening and closing of the inlet and outlet tubes, thus improving the efficiency of sputum suction.

The other end of the pull rod 133 is rotatably installed with a first pressure plate 140. The length of the first pressure plate 140 is less than the length of the liquid inlet pipe 121 and the air outlet pipe 122.

[0030] In some specific implementations, the first slider is symmetrically fixedly installed on the bottom outer side of the pull rod 133, and the inner wall of the sleeve rod 131 is provided with a first sliding groove that matches the first slider.

[0032] In some specific implementations, a second slider is fixedly installed on the outer bottom end of the quadrangular prism 162, and a second sliding groove matching the second slider is provided on the inner wall of the quadrangular groove. This ensures that the air pump 160 moves smoothly when adjusting its position, avoids shaking and deviation, ensures a tight connection between the air pump 160 and the filter assembly 150, maintains the stability of the gas emission system, ensures the normal operation of the device, and improves the user experience.

[0033] Working principle: In use, pull up the first pressure plate 140 until the sealing plate 141 separates from the liquid inlet pipe 121 and the air outlet pipe 122, and pull the bracket 163 to move the air pump 160 upward to above the first pressure plate 140. Rotate the first pressure plate 140 so that the support ring 151 is directly above the air outlet pipe 122. After releasing the first pressure plate 140, the first pressure plate 140 is moved downward by the pulling force of the first spring 132. The downward movement of the first pressure plate 140 moves the support ring... 151 is fitted onto the air outlet tube 122. Then, the bracket 163 is loosened, and the second spring pulls the bracket 163 down. The downward movement of the bracket 163 causes the air pump 160 to move down until the sealing ring is fitted onto the threaded sleeve 152. Finally, the suction tube is fitted onto the inlet tube 121 and the air pump 160 is started. When the first filter 153 needs to be replaced, simply move the first pressure plate 140 back as described above, and then rotate the threaded sleeve 152 to remove it for replacement.
