Description

Technical Field

[0001] This invention relates to the field of pulmonary function testing technology, and in particular to a high-efficiency portable pulmonary function instrument. Background Technology

[0002] A pulmonary function analyzer is a medical testing device used to assess lung function health. It measures lung health by measuring the amount of air exhaled and inhaled. Pulmonary function analyzers come in handheld and non-handheld versions. Handheld pulmonary function testing devices are used to assess a patient's respiratory function and can help detect respiratory diseases in their early stages.

[0003] Patent CN212089534U discloses a portable high-altitude pediatric pulmonary function instrument, comprising an instrument shell, a transmission tube, and a sliding cover. The instrument shell contains a detection element, and its upper surface has a first groove. The right end of the first groove communicates with the outside of the instrument shell. The lower end of the transmission tube extends through the lower wall of the first groove into the interior of the instrument shell and connects to the detection element. The upper end of the transmission tube has a mouthpiece. Limiting plates are fixedly connected to the front and rear walls of the first groove, corresponding to the right side of the transmission tube. A second groove is formed at the upper end of the front wall of the first groove. This invention solves the problem that existing high-altitude pediatric pulmonary function instruments have mouthpieces and transmission tubes that occupy space, are inconvenient to store, and are therefore difficult to carry, burdening medical personnel and affecting the efficiency of pulmonary function testing in primary hospitals. While placing the transmission tube and mouthpiece in the first groove allows for storage and saves space, it does not protect or sterilize the transmission tube and mouthpiece, posing a certain risk during use.

[0004] Currently available handheld pulmonary function analyzers are generally used outdoors. When using them outdoors, the mouthpiece of the pulmonary function analyzer is placed in the mouth, and the lung breathing function is tested by blowing air. However, due to the small size of the handheld pulmonary function analyzer, there are no specific protective measures on the mouthpiece during the carrying process, which leads to contact with external bacteria and unsanitary conditions. In addition, fibers, cotton threads, etc. may adhere to the mouthpiece during the carrying process, which may be inhaled into the body or blown into the device during the test. This will have a negative impact on human health and the instrument itself. Summary of the Invention

[0012] As a preferred embodiment of the present invention, it also includes a clamping plate, which is fixedly attached to the body of the detector.

[0013] As a preferred embodiment of the present invention, it further includes a conical nail, which is fixedly attached to the clamp plate.

[0014] As a preferred embodiment of the present invention, it further includes a disinfection component. The upper part of the sleeve is provided with a disinfection component for disinfecting the sleeve with disinfectant. The disinfection component includes a storage ring, an inlet pipe, an outlet pipe, and ball bearings. The upper part of the sleeve is provided with a storage ring for storing disinfectant. The inner wall of the storage ring is on the same plane as the inner wall of the sleeve.

Detailed Implementation

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0033] Example 1: A high-efficiency portable pulmonary function instrument, such as Figures 1-4As shown, the device includes a detector body 1, an air inlet pipe 2, a three-way connector 3, an air blowing hose 4, an air blowing nozzle 5, a locking device 6, and a shielding assembly 7. The air inlet pipe 2 is connected to the air inlet at the top of the detector body 1, guiding the air blown by the user into the detector body 1. One end of the air inlet pipe 2 is connected to the three-way connector 3, and one of the interfaces on the three-way connector 3 is connected to the air blowing hose 4. The remaining connector is blocked by a cap, leaving an empty connector for adding an extra air blowing hose 4. In actual use, only one air blowing hose 4 needs to be blocked to achieve alternating detection. The end of the air blowing hose 4 is connected to the air blowing nozzle 5, which the user bites onto to blow air. A locking device is located on one side of the detector body 1. Fastener 6, the air hose 4 is fastened to fastener 6. A shielding component 7 is set on the detector body 1 on the same side as fastener 6 to shield the air nozzle 5. Fastener 6 consists of a clamping plate 61 and a limiting plate 62. The clamping plate 61 is fixed to one side of the detector body 1 by bolts. The limiting plate 62 is slidably connected to the clamping plate 61. When in use, the limiting plate 62 is pulled open, and the air hose 4 is then clamped in the clamping plate 61. Then the limiting plate 62 is pushed back to complete the fastening of the air hose 4. The limiting plate 62 consists of a vertical rod and an arc rod. The vertical rod is slidably connected to the clamping plate 61. The arc rod can better pull the limiting plate 62. At the same time, the equipment can be hung when needed for convenient use.

[0034] like Figure 5 and Figure 6 As shown, the shielding assembly 7 includes a compression spring 70, a guide plate 71, a fixing ring 72, and a sleeve 73. The guide plate 71 is fixed to the detector body 1 on the same side as the buckle 6 by bolts. The fixing ring 72 is slidably connected to the guide plate 71 and slides up and down within the guide plate 71. A compression spring 70 is connected between the fixing ring 72 and the guide plate 71. The compression spring 70 is a miniature spring that can maintain the position of the fixing ring 72. The sleeve 73 is fixed to the fixing ring 72 by bolts. The sleeve 73 is detachable. The air nozzle 5 is placed inside the sleeve 73. When the detector body 1 is not in use, the air hose 4 is fastened and then the air nozzle 5 can be inserted into the sleeve 73 to prevent the air nozzle 5 from being exposed and to avoid contact with other external objects.

[0035] like Figure 7 As shown, it also includes an arc-shaped sleeve 74. The part of the air hose 4 near the air nozzle 5 is symmetrically fitted with the arc-shaped sleeve 74. The two arc-shaped sleeves 74 partially wrap around the part of the air hose 4 near the air nozzle 5. The arc-shaped sleeves 74 form a ring-shaped collar. The ring-shaped collar can be inserted into the sleeve 73. When the collar is inserted into the sleeve 73, the air nozzle 5 is completely sealed inside the sleeve 73, further improving the sealing and protection of the air nozzle 5.

[0036] like Figure 8As shown, it also includes a push-out component 8, which is provided on the guide plate 71. The push-out component 8 includes a guide plate 81 and a curved rod 82. The guide plate 71 is hinged to one side of the guide plate 81. The guide plate 81 has a slotted hole in the middle. The fixing ring 72 is slidably connected to the guide plate 81 through a locking shaft. The limiting plate 62 is fixed to one end of the curved rod 82, and the other end of the curved rod 82 is slidably connected to the guide plate 81. The position where the curved rod 82 is slidably connected to the guide plate 81 is between the fixing ring 72 and the guide plate 71. When the limiting plate 62 is pulled to move, the curved rod 82 pushes the guide plate 81 to swing, which causes the fixing ring 72 to move with the sleeve 73, thereby causing the sleeve 73 to disengage from the mouthpiece 5. This achieves the goal of pushing the sleeve 73 open while pulling the limiting plate 62.

[0037] like Figure 9 As shown, it also includes a slag removal component 9. The slag removal component 9 is installed inside the sleeve 73 to remove slag by wiping. The slag removal component 9 includes a piston push rod 91 and a tension spring 92. The piston push rod 91 is slidably connected inside the sleeve 73. The push rod of the piston push rod 91 slides out of the sleeve 73. The piston push rod 91 consists of a circular piston and a vertical push rod. The edge of the piston is made of soft material. After pushing the piston push rod 91, the impurities in the sleeve 73 can be pushed out, thereby achieving the effect of quickly cleaning the impurities inside the sleeve 73. The extension part of the push rod is fitted with a tension spring 92. The tension spring 92 is used to keep the piston push rod 91 from returning to its original position after it is pushed. At the same time, there is a hole at the bottom of the sleeve 73, so it will not be affected when the piston push rod 91 moves up or down.

[0038] like Figure 10 As shown, it also includes a clamp 10. The clamp 10 is fixed to the rear side of the detector body 1 by bolts. The clamp 10 can be used to clip the detector body 1 onto a cloth belt or clothing for easy carrying. The clamp 10 is made of elastic plastic or iron sheet. At the same time, the edges of the clamp 10 are chamfered to prevent the clamp 10 from scratching the user.

[0039] like Figure 11 As shown, it also includes a conical nail 101, which is fixed to the clamp 10. The conical nail 101 can make the clamp 10 fasten tightly to the fabric to prevent slippage.

[0040] like Figure 12As shown, it also includes a disinfection component 11. The upper part of the sleeve 73 is equipped with a disinfection component 11 for disinfecting the sleeve 73 with disinfectant. The disinfection component 11 includes a storage ring 111, an inlet pipe 112, an outlet pipe 113, and a ball bearing 114. The upper part of the sleeve 73 is equipped with a storage ring 111 for storing disinfectant. The inner wall of the storage ring 111 is on the same plane as the inner wall of the sleeve 73. A device for adding disinfectant to the storage ring 111 is provided on the upper part of the storage ring 111. The venom feed pipe 112 is connected to the storage ring 111. A cap is threaded onto the feed pipe 112, which blocks the top of the feed pipe 112. Eight discharge pipes 113 are evenly spaced on the inner wall of the storage ring 111. One end of the discharge pipe 113 is connected to the inside of the sleeve 73, and the other end is connected to the inside of the storage ring 111. Each discharge pipe 113 is equipped with a rotating ball bearing 114, and the diameter of the ball bearing 114 is the same as the diameter of the discharge pipe 113.

[0041] Before using the equipment, first unscrew the cap on the feed pipe 112, then add disinfectant into the storage ring 111. After the disinfectant is added, screw the cap back on. When the piston rod 91 moves upward, the piston rod 91 contacts the ball 114, causing the ball 114 to rotate. Because the side of the ball 114 facing the storage ring 111 is covered with disinfectant, the side with the disinfectant is facing the inside of the sleeve 73. When the piston rod 91 contacts the ball 114, the disinfectant sticks to the piston rod 91. When the piston rod 91 moves up and down to clean the inside of the sleeve 73, the inside of the sleeve 73 is disinfected at the same time through the disinfectant.

[0042] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
