Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to a breath test instrument for measuring red blood cell lifespan. Background Technology

[0002] Currently, Chinese Patent Publication No. CN219758136U discloses an exhaled red blood cell lifespan analyzer, which includes a microprocessor, a sample air bag, a bottom air bag, an air inlet pipe, a carbon monoxide detection mechanism, an air delivery pipe, a carbon dioxide detection mechanism, and an exhaust pipe. The air inlet pipe is equipped with an air pump, and the carbon monoxide detection mechanism is equipped with a constant temperature mechanism. This discloses a tester with a general existing structure. However, after use, the user may not seal the air bag, causing the air bag to leak and requiring re-inhalation. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a breath tester for measuring red blood cell lifespan, which solves the technical problem of air leakage due to improper operation after the air bag is used.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a breath test device for measuring red blood cell lifespan, comprising a body, an alveolar air inlet, an ambient background air inlet, and an inverted air bag inlet sequentially disposed at the front end of the body, a control panel disposed on one side of the top surface of the body, and a display disposed on the top surface of the body. The front end of the body is provided with an air bag for inserting into the alveolar air inlet, the ambient background air inlet, or the inverted air bag inlet. The air bag includes a bag body, a bag mouth disposed at the top of the bag body, and a connector screwed onto the outside of the bag mouth. The connector includes an external threaded ring extending from the top of the connector, a horizontal plate in the middle of the connector, a central hole in the middle of the horizontal plate, a detachable sealing plug located at the central hole of the horizontal plate, and an air inlet located on the horizontal plate and spaced apart from the central hole. The sealing plug has an outer ring rubber on one side for sealing the air inlet, a hollow part in the middle of the sealing plug, and a filling area on the other side of the sealing plug for sealing the hollow part. The body has positioning pins at the alveolar air inlet, the background air inlet, and the inflatable bag inlet.

[0005] Furthermore, a sealing cap is screwed onto the top of the connector.

[0006] Furthermore, the top of the sealing cap is provided with a protrusion, the top of which is a pointed portion.

[0007] Furthermore, the sealing plug has an outer ring on one side of the filling area with an outer diameter larger than the central hole of the transverse plate, and the thickness of the outer ring of the sealing plug gradually decreases from the outside to the middle.

[0008] Furthermore, the sealing plug is provided with a pull ring at the filling area, and the pull ring is integrally formed with the sealing plug.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0010] This erythrocyte lifespan determination breath test device uses a sealing plug. During use, when the air bag collects air, the airflow first passes through the connector. When the user exhales, the air flows through the air inlet. After completion, the outer ring rubber of the sealing plug deforms, allowing air to enter the air bag through the horizontal plate. When the gas collection in the air bag is complete and it expands, and the user stops exhaling, the air bag is affected by the internal air pressure, and the outer ring rubber will seal the air inlet on the horizontal plate to prevent the air bag from leaking due to improper operation after use.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figures 1 to 6 This embodiment provides a breath test device for measuring red blood cell lifespan, including a body 1, an alveolar air inlet 2, an ambient background air inlet 3 and an inverted air bag inlet 4 arranged sequentially at the front end of the body 1, a control panel 5 located on one side of the top surface of the body 1, and a display 6 located on the top surface of the body 1. The front end of the body 1 is provided with an air bag 7 for inserting into the alveolar air inlet 2, the ambient background air inlet 3 or the inverted air bag inlet 4.

[0019] The air bag 7 includes a bag body 701, a bag mouth 702 located at the top of the bag body 701, a connector 703 screwed onto the outside of the bag mouth 702, an external threaded ring 704 extending from the top of the connector 703, a horizontal plate 705 located in the middle of the connector 703, a central hole 706 located in the middle of the horizontal plate 705, a sealing plug 707 detachably located at the central hole 706 of the horizontal plate 705, and an air inlet 708 located on the horizontal plate 705 and spaced apart from the central hole 706. The sealing plug 707 has an outer ring rubber 709 on one side for sealing the air inlet 708, a hollow portion 710 in the middle of the sealing plug 707, and a filling area 711 on the other side of the sealing plug 707 for sealing the hollow portion 710. The body 1 has positioning pins 8 located at the alveolar air inlet 2, the environmental background air inlet 3, and the inverted air bag inlet 4.

[0020] During the air bag collection process, the airflow is first passed through the connector. When the user exhales, the airflow will pass through the air inlet. After completion, the outer ring rubber of the sealing plug will deform, allowing air to enter the air bag through the horizontal plate. When the air bag has finished collecting gas and expands, and the user stops exhaling, the air bag will be affected by the internal air pressure, and the outer ring rubber will seal the air inlet on the horizontal plate to prevent the air bag from leaking due to improper operation after use.

[0021] When it is necessary to insert the alveolar air inlet, background air inlet, or inflatable bag inlet on the body, the positioning pin will contact the sealing plug and push it down, making it easier for the body to collect air from the inflatable bag.

[0022] The connector 703 is screwed with a sealing cap 9 at the top. The sealing cap helps prevent leakage of the sealing plug during storage and improves the airtightness of the air bag.

[0023] The sealing cap 9 has a protrusion 10 on its top, and the top of the protrusion 10 is a pointed part 11, which can be referred to as... Figure 4 and Figure 5 When inserting it into the machine body, unscrew the sealing cap and insert it into the middle hole on the horizontal plate. The sealing plug will be pushed down into the air bag. The diameter of the tip of the convex column is reduced. When inserted, the sealing plug contracts to wrap around the tip of the convex column, and there is less resistance when pushing it down, making it easy to use.

[0024] The sealing plug 707 is located on one side of the filling area 711 and has an outer ring 712 with an outer diameter larger than the central hole 706 of the horizontal plate 705. The outer ring 712 of the sealing plug 707 gradually decreases in thickness from the outside to the middle. The outer ring gradually decreases in thickness towards the middle and its shape becomes conical. When the protrusion is inserted, it is beneficial to guide the protrusion and prevent it from being inconvenient to insert into the center of the sealing plug.

[0025] The sealing plug 707 has a pull ring 713 located in the filling area 711. The pull ring 713 is integrally formed with the sealing plug 707. (See reference...) Figure 6It is not necessary to set the protruding post. After unscrewing the sealing cap, you can directly pull it out through the pull ring and then insert it into the alveolar air inlet 2, the environmental background air inlet 3, or the inlet bag inlet 4.
