Description

Technical Field

[0001] This utility model relates to the field of medical gas terminal technology, specifically to a medical gas terminal with flow regulation. Background Technology

[0002] Medical gas terminals, also known as quick connectors, are important components of medical central oxygen supply systems. They are devices that can be connected or disconnected using only two or one hand and are typically installed on medical gas distribution equipment in operating rooms, wards, emergency rooms, and other similar locations.

[0003] According to the Chinese patent publication number CN209019657U, "A Medical Gas Nebulization Terminal", the main description is that the provided medical gas nebulization terminal can steplessly adjust the gas flow rate within a certain range, which facilitates the adjustment of the nebulized gas flow rate.

[0004] In actual use, medical gas terminals typically control the flow rate through regulating valves. However, over time, impurities in the gas can gradually clog the flow meter regulating valve, leading to poor valve sealing and inaccurate flow regulation.

[0005] Therefore, a medical gas terminal with flow regulation is proposed to solve the problem that long-term use can cause impurities in the gas to clog the flow meter regulating valve, resulting in poor flow regulation effect of the valve. Utility Model Content

[0006] The technical problem this invention aims to solve is that prolonged use can cause impurities in the gas to clog the flow meter regulating valve, resulting in poor flow regulation. Therefore, this invention proposes a medical gas terminal with flow regulation.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a medical gas terminal with flow regulation, including a terminal shell, an air inlet pipe fixedly connected to one side of the terminal shell, a connecting frame fixedly connected to the upper side of the terminal shell, a support sleeve threadedly connected to the upper side of the terminal shell above the connecting frame, a ring sleeve threadedly connected to the inner side of the support sleeve, a rotating plate rotatably connected inside the ring sleeve, an air outlet pipe fixedly connected to the upper end of the rotating plate, a rotating sleeve fixedly connected to the upper end of the rotating plate, a connecting rod fixedly connected to the bottom end of the rotating plate, a semi-cylindrical block sleeved on the bottom side of the connecting rod, and an L-shaped groove opened on the opposite side of each of the two semi-cylindrical blocks, the bottom side of the L-shaped groove communicating with the air inlet pipe.

[0008] As a preferred technical solution of this utility model, the bottom side of the support sleeve is in contact with a washer, and the washer is sleeved on the outside of the terminal shell. By setting the washer, the tightness of the connection is increased.

[0009] As a preferred technical solution of this utility model, the upper end of the support sleeve is in contact with a slider, which is rotatably embedded on the four sides of the rotating sleeve. By setting the slider, the friction force of the rotating sleeve is reduced.

[0010] As a preferred technical solution of this utility model, the two mutually distant sides of the support sleeve are threaded with positioning rods, and the positioning rods are inserted into the upper side of the ring sleeve. By setting the positioning rods, the rotating sleeve and the ring sleeve can rotate coaxially.

[0011] As a preferred technical solution of this utility model, the semi-cylindrical block is provided with yin and yang grooves, which are located on opposite sides of the two semi-cylindrical blocks. By setting the yin and yang grooves, the connection effect of the two semi-cylindrical blocks can be increased.

[0012] This utility model has the following advantages: by manually adjusting the rotating sleeve, without the positioning rod being connected to the ring sleeve, the channel formed by the two L-shaped grooves can be misaligned with the port of the air inlet pipe, thereby changing the cross-sectional area of ​​the contact surface and realizing flow regulation. At the same time, the positioning rod connects to the ring sleeve and makes the rotating sleeve rotate, thereby facilitating the disassembly of the ring sleeve and the semi-cylindrical block, achieving the effect of easy removal and cleaning.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figs. 1-3The illustrated medical gas terminal with flow regulation includes a terminal housing 1. An inlet pipe 2 is fixedly connected to one side of the terminal housing 1. A connecting frame 3 is fixedly connected to the upper side of the terminal housing 1. A support sleeve 4 is threadedly connected to the upper side of the connecting frame 3. A ring sleeve 5 is threadedly connected to the inner side of the support sleeve 4. Rotating the ring sleeve 5 allows it to move up or down within the support sleeve 4. A rotating plate 6 is rotatably connected inside the ring sleeve 5. An outlet pipe 7 is fixedly connected to the upper end of the rotating plate 6. The outlet pipe 7 is used to connect to external devices. A rotating sleeve 9 is fixedly connected to the upper end of plate 6. When rotating the rotating sleeve 9, the semi-cylindrical block 10 can be rotated without the positioning rod 14 connecting to the ring sleeve 5. This controls the misalignment of the channel formed by the L-shaped groove 11 with the port of the air intake pipe 2, thereby changing the air intake cross section and achieving the effect of flow regulation. A connecting rod 8 is fixedly connected to the bottom end of rotating plate 6. A semi-cylindrical block 10 is sleeved on the bottom side of the connecting rod 8. An L-shaped groove 11 is opened on the opposite side of the two semi-cylindrical blocks 10. The bottom side of the L-shaped groove 11 is connected to the air intake pipe 2.

[0019] Among them, the bottom side of the support sleeve 4 is in contact with a washer 12, which is sleeved on the outside of the terminal housing 1. By setting the washer 12, the tightness of the connection between the connecting frame 3 and the support sleeve 4 can be increased.

[0020] Among them, the upper end of the support sleeve 4 is in contact with the slider 13, and the slider 13 is rotatably embedded on the four sides of the rotating sleeve 9. By setting the slider 13, the rotational friction of the support sleeve 4 is reduced.

[0021] The support sleeve 4 has a positioning rod 14 threadedly connected to both sides that are far apart from each other. The positioning rod 14 is inserted into the upper side of the ring sleeve 5. By setting the positioning rod 14, different effects can be achieved by connecting to or moving away from the ring sleeve 5.

[0022] The semi-cylindrical block 10 is provided with a yin-yang groove 15, which is located on the opposite side of the two semi-cylindrical blocks 10. By setting the yin-yang groove 15, the stability of the semi-cylindrical block 10 during rotation is increased.

[0023] Working principle: Connect the outlet pipe 7 to the external equipment. When the gas terminal needs flow adjustment, medical staff can manually rotate the positioning rod 14 so that the end of the positioning rod 14 is not inserted into the ring sleeve 5. Then, the rotating sleeve 9 rotates, and the semi-cylindrical block 10 rotates through the rotating plate 6 and the connecting rod 8. At this time, the channel port formed by the L-shaped groove 11 is misaligned with the port of the inlet pipe 2, and the cross-section changes, thereby realizing flow adjustment. When the gas terminal needs to be disassembled for maintenance, the positioning rod 14 can be inserted into the ring sleeve 5, and the rotating sleeve 9 can be rotated, so that the ring sleeve 5 moves upward and is finally disassembled. At this time, the ring sleeve 5 and the semi-cylindrical block 10 can be removed from the terminal housing 1, which makes it easy to clean the L-shaped groove 11.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
