Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical supplies, and in particular to a lung function testing cover for tracheotomized patients. Background Technology
[0002] Pulmonary function testing is an essential examination for respiratory diseases. It is mainly used to detect the patency of the airways and the size of the lungs. It has important clinical value in the early detection of lung and airway lesions, assessing the severity and prognosis of the disease, evaluating the efficacy of drugs or other treatments, identifying the cause of dyspnea, diagnosing the location of lesions, assessing the lung function's tolerance to surgery or labor intensity, and monitoring critically ill patients.
[0003] The equipment used for pulmonary function testing consists of a main unit and tubing, with a mouthpiece connected to the end of the tubing. During the test, the subject places the mouthpiece in their mouth, closes their nose, breathes through their mouth, and adjusts their breathing rhythm and the duration of inhalation and exhalation. The main unit then displays the relevant data for the pulmonary function test.
[0004] Tracheostomy patients often need to undergo lung function tests, but because the air passage for tracheostomy patients is the opening removed from the neck, they cannot bite down on a mouthpiece and need a matching device. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a lung function testing mask for tracheotomized patients with low usage cost.
[0006] The technical solution adopted in this utility model is as follows: the lung function testing mask for tracheotomized patients includes a testing mask body and a disposable isolation material; the testing mask body includes a connecting tube and a cone-shaped mask, the cone-shaped mask being larger at the front and smaller at the back, the connecting tube being coaxially arranged with the cone-shaped mask and connected to the rear end of the cone-shaped mask, the rear part of the connecting tube being the detector connection part, and the front end of the cone-shaped mask being provided with a flexible pad; the disposable isolation material at least covers the surface of the flexible pad and the inner surface of the cone-shaped mask.
[0007] Furthermore: the main body of the detection cover includes a fixing structure, the front of the connecting tube is a plastic tube mounting part, the front end of the conical cover has an outer flange, and the flexible pad is connected to the outer flange; the disposable isolation material includes a conical film sleeve, a rigid plastic tube and an elastic ring, the rigid plastic tube and the elastic ring are respectively connected to the small end and the large end of the conical film sleeve; the conical film sleeve is fitted on the front end of the conical cover and covers the inner surface of the conical cover, the elastic ring shrinks, the outer flange restricts the elastic ring from slipping off, the rigid plastic tube is inserted into the plastic tube mounting part and cooperates with the plastic tube mounting part, and the fixing structure restricts the forward movement of the rigid plastic tube.
[0008] Furthermore, the plastic tube mounting part has a through hole; the fixing structure includes a clamping rod, a clamping head and an elastic element, the middle part of the clamping rod is hinged to the plastic tube mounting part and the hinge point is located behind the through hole, the clamping head is correspondingly set to the through hole and connected to the front end of the clamping rod, and the elastic element is set between the rear end of the clamping rod and the connecting pipe, the elastic element causes the clamping head to move inward to clamp the rigid plastic tube.
[0009] Furthermore, the elastic element is a torsion spring.
[0010] Furthermore, the fixing structure is a tightening screw, which is threadedly connected to the plastic tube mounting part and tightens the rigid plastic tube.
[0011] Furthermore, the front end of the rigid plastic tube has a positioning flange that fits against the front end face of the plastic tube mounting part, and the rear end of the rigid plastic tube is flush with the rear end of the plastic tube mounting part.
[0012] Furthermore, the flexible pad includes a silicone jacket and foam filling the silicone jacket.
[0013] The beneficial effects of this utility model are as follows: When using this utility model, the detector connection part is connected to the pipeline of the lung function testing equipment, the cone-shaped mask is attached to the neck of the test subject and covers the incision in the neck, and then the patient breathes according to the testing requirements to complete the lung function test.
[0014] While lung function testing can be performed using only the main body of the testing mask, its surface cannot be reused directly because the front end of the mask comes into contact with the test subject and moisture from the patient's breath adheres to it. The main body of the testing mask is also more expensive than the existing mouthpiece. Since lung function tests are completed very quickly, using the main body only once is wasteful and places a heavy burden on the test subject.
[0015] This application incorporates a disposable isolator that covers at least the surface of the flexible pad and the inner surface of the cone-shaped hood. This disposable isolator is the only part that comes into contact with the test subject and adheres to their exhaled moisture. The cost of the disposable isolator can be very low, and it is replaced after each patient's test, ensuring the safety of the lung function test while reducing the testing costs borne by the test subject.

Detailed Implementation
[0021] The following is in conjunction with the appendix Figure 1-4 This utility model will be described in detail.
[0022] The tracheostomy patient lung function testing mask includes a main body 1 and a disposable isolation device 2. The main body 1 includes a connecting tube 11 and a cone 12, which is wider at the front and narrower at the back. The connecting tube 11 is coaxially arranged with the cone 12 and connected to the rear end of the cone 12. The rear part of the connecting tube 11 is a detector connection part 111. A flexible pad 121 is provided at the front end of the cone 12. The disposable isolation device 2 is detachably connected to the main body 1 and at least covers the surface of the flexible pad 121 and the inner surface of the cone 12.
[0023] When using this invention, the detector connection part 111 is connected to the detection equipment tube 3, the cone-shaped cover 12 is attached to the neck of the test subject and covers the incision in the neck, and then the patient breathes according to the test requirements to complete the lung function test.
[0024] While lung function testing can be performed using only the main body 11 of the testing mask, its surface cannot be reused directly because the front end of the mask body 11 comes into contact with the test subject and moisture from the patient's breath adheres to its surface. The main body 11 is also more expensive than existing mouthpieces. Since lung function tests are completed very quickly, using the main body 11 only once is wasteful and places a heavy burden on the test subject.
[0025] This application includes a disposable isolator 2, which at least covers the surface of the flexible pad 121 and the inner surface of the cone-shaped hood 12. The disposable isolator 2 is the only material that comes into contact with the test subject and adheres to the moisture exhaled by the test subject. The disposable isolator 2 can be very inexpensive, and it is replaced after each patient's test, ensuring the safety of the lung function test while reducing the testing costs borne by the test subject.
[0026] The detector connector 111 is used to connect to the detection device tube 3, and is typically fitted onto the detection device tube 3. The detector connector 111 simply needs to have a hole that matches the detection device tube 3. The conical shield 12 is used to cover the tracheotomy incision. To ensure a good fit to the subject's neck, the front of the conical shield 12 can be... Figure 2 As shown, it has a certain curvature. The flexible pad 121 conforms to the neck of the test subject and can deform to ensure good fit in all areas, thereby ensuring a sealing effect. Specifically, the flexible pad 121 may include a silicone outer shell and foam filled inside the silicone outer shell. Thus, the flexible pad 121 can have a large amount of deformation.
[0027] The preferred configuration of the disposable isolation device 2 is as follows: The main body 1 of the detection cover includes a fixing structure 13, the front part of the connecting tube 11 is a plastic tube mounting part 112, the front end of the conical cover 12 has an outer flange 122, and a flexible pad 121 is connected to the outer flange 122; the disposable isolation device 2 includes a conical film sleeve 22, a rigid plastic tube 21, and an elastic ring 23, the rigid plastic tube 21 and the elastic ring 23 are respectively connected to the small end and the large end of the conical film sleeve 22; the conical film sleeve 22 is fitted on the front end of the conical cover 12 and covers the inner surface of the conical cover 12, the elastic ring 23 shrinks, the outer flange 122 restricts the elastic ring 23 from slipping off, the rigid plastic tube 21 is inserted into the plastic tube mounting part 112 and cooperates with the plastic tube mounting part 112, and the fixing structure 13 restricts the forward movement of the rigid plastic tube 21. The elastic ring 23 can be a rubber band.
[0028] When installing the disposable isolator 2, the elastic ring 23 is stretched, and the front end of the conical film sleeve 22 is placed on the front end of the conical cover 12. The elastic ring 23 is located behind the outer flange 122. After the elastic ring 23 shrinks, it is blocked by the outer flange 122, limiting its slippage. Then, the rigid plastic tube 21 is inserted into the plastic tube mounting part 112, and its movement is restricted by the fixing structure 13. When removing the disposable isolator 2, the fixing structure 13 is released, the elastic ring 23 is stretched to disengage it from the outer flange 122, and then it can be removed by pulling forward. In this way, the installation and removal of the disposable isolator 2 are relatively convenient. Preferably, the front end of the rigid plastic tube 21 has a positioning flange 211, which fits against the front end face of the plastic tube mounting part 112, and the rear end of the rigid plastic tube 21 is flush with the rear end of the plastic tube mounting part 112. With this disposable isolation material 2, the covering area reaches its maximum. After the lung function testing mask for tracheotomized patients is installed, the entire inner surface of the main body 1 of the testing mask is covered.
[0029] The specific structure of fixed structure 13 can be as follows: Figure 1 and Figure 2As shown, the plastic tube mounting part 112 has a through hole 113; the fixing structure 13 includes a clamping rod 131, a clamping head 132, and an elastic element 133. The middle part of the clamping rod 131 is hinged to the plastic tube mounting part 112, and the hinge point is located behind the through hole 113. The clamping head 132 is correspondingly arranged with the through hole 113 and connected to the front end of the clamping rod 131. The elastic element 133 is disposed between the rear end of the clamping rod 131 and the connecting pipe 11. The elastic element 133 causes the clamping head 132 to move inward and clamp the rigid plastic tube 21. Specifically, the elastic element 133 is a torsion spring.
[0030] Pressing down the rear end of the clamping lever 131 causes the clamping head 132 to tilt upwards, disengaging it from the rigid plastic tube 21, allowing for the installation and removal of the disposable isolation device 2. Without pressing down the rear end of the clamping lever 131, the elastic element 133 causes the clamping head 132 to move inwards and clamp the rigid plastic tube 21. Since the disposable isolation device 2 is not subjected to significant force during the use of the tracheostomy patient's lung function testing mask, this fixing method is reliable. Contact fixing is simple; just press down the clamping lever 131, and fixing is easy; once secured, it is released.
[0031] The specific structure of fixed structure 13 can also be as follows: Figure 4 As shown, the fixing structure 13 is a tightening screw 134, which is threadedly connected to the plastic tube mounting part 112 and tightens the rigid plastic tube 21. Tightening the tightening screw 134 fixes the plastic tube mounting part 112, and loosening it releases the fixation. This fixing method has a simpler structure, but the operation is more cumbersome than the previous fixing method.
