Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and particularly relates to a pulmonary function detection device. Background Art

[0002] Pulmonary function examination is one of the necessary examinations for respiratory diseases, mainly used to detect the patency of the respiratory tract and the size of lung volume. It has important clinical value in early detection of lung and airway lesions, assessment of the severity and prognosis of diseases, evaluation of the efficacy of drugs or other treatment methods, identification of the causes of dyspnea, diagnosis of the lesion site, assessment of the tolerance of lung function to surgery or labor intensity, and monitoring of critically ill patients.

[0003] For the existing pulmonary function detection device, after use, the blowing end needs to be replaced. When replacing, the hand is easily contaminated with the saliva attached to the blowing end, which may pose a health hazard. Therefore, we propose a pulmonary function detection device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that for the existing pulmonary function detection device, after use, the blowing end needs to be replaced, and when replacing, the hand is easily contaminated with the saliva attached to the blowing end, which may pose a health hazard.

[0005] To achieve the above technical purpose, the technical scheme adopted by the utility model is as follows:

[0006] A pulmonary function detection device includes a detector body and an acquisition component electrically connected to the detector body through a data cable. The acquisition component includes a detection handle with a humidity sensor, a pressure sensor and an airflow sensor integrated inside, a trachea and a blowing tube. An input port is provided on the detection handle. The trachea is fixedly inserted into the detection handle, and the input port is communicated with the trachea. A connecting cylinder is fixedly installed at one end of the blowing tube, and the connecting cylinder is movably inserted into the end of the trachea. A rubber layer is provided on the outer wall of the connecting cylinder. When the connecting cylinder extends into the trachea, the connecting cylinder is in close contact with the inner wall of the trachea. The other end of the blowing tube is a cylindrical structure with a gradually decreasing inner diameter. A rubber ring is fixedly installed at the end of the blowing tube far from the trachea. A fixing ring is fixedly installed on the blowing tube, and a folding sleeve is fixedly installed on the side of the fixing ring far from the trachea.

[0007] Further limited, two soft magnetic strips are fixedly installed at the end of the folding sleeve far from the fixing ring, and the sides of the two soft magnetic strips close to each other have opposite magnetic poles and attract each other. With such a structural design, after the folding sleeve is stretched to wrap the end of the blowing tube, the two soft magnetic strips can attract each other, so that the end of the folding sleeve is in a contracted state, further reducing the probability of contact between the hand and the saliva at the blowing end.

[0008] It is further defined that a rubber sleeve is fixedly provided at one end of the air blowing tube close to the air guide tube, and a plurality of anti-slip grooves are provided on the rubber sleeve. Such a structural design can increase the friction between the hand and the air blowing tube through the rubber sleeve, so as to facilitate the disassembly and assembly of the air blowing tube.

[0009] It is further defined that the air guide tube is provided with a strip opening, a spring sheet is fixedly installed on the air guide tube, the end of the spring sheet extends into the strip opening, a clamping block is fixedly installed on the end of the spring sheet, and a clamping groove matched with the clamping block is provided on the connecting tube. With such a structural design, the spring sheet can fit into the clamping groove of the connecting tube with the clamping block, thereby clamping the air blowing tube to the air guide tube.

[0010] It is further defined that the card block is fixedly connected with a drawstring, and the end of the drawstring passes through the strip opening and is fixedly installed with a draw ring. With such a structural design, the card block can be pulled out of the card slot through the draw ring and the drawstring, so as to facilitate the disassembly of the air blowing tube.

[0011] The utility model adopting the above technical solution has the following advantages:

[0012] The utility model can collect lung function data and display it through the collection component cooperating with the detector body. After the test is completed, the foldable sleeve can be stretched until the foldable sleeve completely wraps the blowing end of the blowing tube, so as to prevent the hands from being contaminated with saliva and make it more convenient to disassemble the blowing tube.

[0031] Such as Figures 1 to 6As shown in the figure, a pulmonary function detection device of the present utility model includes a detector body 1 and an acquisition component 2 that is electrically connected to the detector body 1 through a data cable. The acquisition component 2 includes a detection handle 21 with a humidity sensor, a pressure sensor, and an airflow sensor integrated inside, an air duct 22, and a blowing tube 23. An input port is provided on the detection handle 21. The air duct 22 is fixedly inserted into the detection handle 21, and the input port is communicated with the air duct 22. One end of the blowing tube 23 is fixedly installed with a connection cylinder 230. The connection cylinder 230 is movably inserted into the end of the air duct 22. The outer wall of the connection cylinder 230 is provided with a rubber layer. When the connection cylinder 230 extends into the air duct 22, the connection cylinder 230 closely adheres to the inner wall of the air duct 22. The other end of the blowing tube 23 is a cylindrical structure with a gradually decreasing inner diameter. A rubber ring 231 is fixedly installed at the end of the blowing tube 23 away from the air duct 22. The rubber ring 231 can improve the comfort during oral occlusion. A fixing ring 232 is fixedly installed on the blowing tube 23. A folding sleeve 233 is fixedly installed on the side of the fixing ring 232 away from the air duct 22.

[0032] Two soft magnetic strips 2331 are fixedly installed at the end of the folding sleeve 233 away from the fixing ring 232. The sides of the two soft magnetic strips 2331 close to each other have opposite magnetic polarities and attract each other. When the folding sleeve 233 is in a contracted state, the two soft magnetic strips 2331 are attached to the outer wall of the blowing tube 23. When the folding sleeve 233 is in a stretched state and completely wraps the blowing end of the blowing tube 23, and there is no external force pressing on the two soft magnetic strips 2332, the two soft magnetic strips 2331 can attract each other, making the end of the folding sleeve 233 in a closed state, further avoiding hand contact with saliva.

[0033] A rubber sleeve 24 is fixedly sleeved on the blowing tube 23 near the air duct 22. A plurality of anti-slip grooves are provided on the rubber sleeve 24. The anti-slip grooves and the rubber sleeve 24 can increase the friction between the hand and the blowing tube 23, making it more convenient to disassemble and assemble the blowing tube 23.

[0034] A strip-shaped opening 221 is provided on the air duct 22. A elastic piece 222 is fixedly installed on the air duct 22.

The end of the pull rope 2231 passes through the strip-shaped opening 221 and is fixedly installed with a pull ring 2232.

[0035] The usage method of the present utility model is as follows:

[0036] In use, take an unused blowing tube 23, hold it by hand at the rubber ring 231 part, align the connecting cylinder 230 with the end of the air guide tube 22, apply force to insert the connecting cylinder 230 into the air guide tube 22 until the locking block 223 is snapped into the card slot 2301 under the elastic force of the elastic piece 222, and the blowing tube 23 is locked at the end of the air guide tube 22;

[0037] When blowing air at the blowing tube 23, the acquisition assembly 2 and the detector body 1 can cooperate to test the lung function. After the detection is completed, hold the detection handle 21 with one hand, pinch the connection part of the two soft magnetic strips 2331 with the other hand, and stretch the folding sleeve 233 through the two soft magnetic strips 2331 so that the folding sleeve 233 completely wraps the blowing end of the blowing tube 23. At this time, release the force applied to the two soft magnetic strips 2331, and the two soft magnetic strips 2331 attract each other under the magnetic force, so that the mouth of the folding sleeve 233 is in a closed state to avoid contact between the hand and the saliva attached to the blowing tube 23;

[0038] When it is necessary to disassemble the blowing tube 23 for replacement, pull the locking block 223 through the pull rope 2231 so that the locking block 223 disengages from the card slot 2301, and the connection between the connecting cylinder 230 and the air guide tube 22 can be released. At this time, apply force to pull out the connecting cylinder 230 from the air guide tube 22.
