The outer wall of the pillar 14 is provided with a support plate, and a high-pressure nozzle 38 and an ultraviolet germicidal lamp 39 corresponding to the positions of the inlet 28 and the outlet 27 are arranged at the lower part of the support plate. pipeline;

The principle of UV germicidal lamp 39 is: the use of ultraviolet rays of appropriate wavelengths can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, resulting in growth cell death and/or regenerative cell death. The effect of sterilization and disinfection. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics. It uses specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to irradiate flowing water to remove various bacteria, viruses, parasites, algae and Other pathogens kill directly. The ultraviolet light used for disinfection is C-wave ultraviolet, and its wavelength range is 200-275nm, and the band with the strongest bactericidal effect is 250-270nm. The ultraviolet germicidal lamp 39 is irradiated on the connection between the outlet pipe 29 and the outlet 27, and the connection between the inlet 28 and the gas supply end, because there is usually a gap at the connection, which breeds bacteria, viruses, etc., and the sanitation of the connection is guaranteed by the treatment of ultraviolet rays;

The high-pressure disinfectant liquid supply pipeline provides high-pressure disinfectant, and under the treatment of the high-pressure nozzle 38, the high-pressure disinfectant is atomized and sprayed, so that the gas outlet pipe 29, the outlet 27, and the inlet 28 can be sterilized before being connected to the gas supply end, and It can blow away dust and other impurities on the surface.

A cleaning hole is opened on the side wall of the unit chamber, and the cleaning hole is closed by an embedded sealing gasket 26; as shown in FIG. The rubber pad 26 is arranged on the lower side of the partition plate 25 . When cleaning, the sealing rubber pad 26 can be pulled off to clean the interior of the unit chamber. The sealing rubber pad 26 is arranged on the side wall of the air chamber 24 facing the pillar 14 , Under the blocking of the pillar 14 , the sealant pad 26 is not easy to fall off, and the outside is not easily touched. When cleaning, the air chamber 24 needs to be disassembled from the pillar 14 .

The mounting seat 15 is provided with a bottle hanging rod 16 ; the mounting seat 15 is hollow, the bottle hanging rod 16 is longitudinally slidably inserted in the mounting seat 15 , and the side wall of the mounting seat 15 slides on the side wall. A lock rod 18 is inserted, and one end of the lock rod 18 facing the bottle hanging rod 16 is provided with a locking tooth 19 , and the outer wall of the bottle hanging rod 16 is provided with a positioning tooth corresponding to the position of the locking tooth 19 bar 17, a limit stop is set on the outer wall of the lock rod 18, and a support spring 20 is supported between the limit stop and the inner wall of the mounting seat 15;

According to different infusion situations, the height of the hanging bottle hanging rod 16 needs to be adjusted, which is suitable for different infusion environments. When adjusting, the locking rod 18 is pulled outward, and the support spring 20 is compressed, so that the locking rod 18 drives the locking tooth 19 from the The positioning rack 17 is disengaged, thereby removing the restriction on the positioning rack 17. At this time, according to the use situation, adjust the height of the bottle hanging rod 16. After adjustment, release the locking rod 18, and the elastic force of the supporting spring 20 Under the action, the locking rod 18 pushes the locking teeth 19 to move toward the positioning rack 17 and is stuck with the positioning rack 17, so that the bottle hanging rod 16 cannot move longitudinally.

The damping friction pad 23 is in contact with the friction roller 22. When the gear 21 rotates up and down with the positioning rack 17, it will drive the friction roller 22 to rotate, and the damping friction pad 23 and the friction roller 22 rotate relative to each other. The friction roller 22 rotates slowly, thereby preventing the bottle hanging rod 16 and the positioning rack 17 from moving too fast, making the movement and adjustment of the bottle hanging rod 16 safer, and preventing the bottle hanging rod 16 from falling rapidly under the action of gravity.

The outer walls of the bottle hanging rod 16 and the locking rod 18 are axially provided with slide bars, and the connection positions of the mounting seat 15 and the bottle hanging rod 16 and the locking rod 18 are provided with a limit suitable for the slide bars. Bit chute.

Through the cooperation of the slide bar and the limit chute, the bottle hanging rod 16 and the locking rod 18 can only linearly translate relative to the mounting seat 15 but cannot rotate, so that the locking teeth 19 and the locking rod 18, the gear 21 and the positioning teeth Bar 17 is in the right position.

Working principle: Install the mounting plate 1 at the installation place, and when the device is used to provide the corresponding gas to the patient, the drive motor 4 drives the upper half shaft 3 to rotate through the pulley mechanism 5, and the rotating upper half shaft 3 is linked to the lower half shaft 6 and the lower part. The structure enables the bottle hanging rod 16 and the air chamber 24 to rotate close to the patient.

The folding adjustment motor 13 can drive the lower horizontal support plate 12 and the lower structure to rotate through the connecting shaft 11. When the upper horizontal support plate 10 and the lower horizontal support plate 12 are staggered, the bottle hanging rod 16 and the air chamber 24 on the lower side are deviated from the lower side. The axis of the half shaft 6 can thus expand the moving range of the bottle hanging rod 16 and the air chamber 24 .

Before use, the outlet 27, the inlet 28, the connector 35 and the gas supply end are sterilized and cleaned in advance through the high-pressure nozzle 38 and the ultraviolet germicidal lamp 39, and then the connector 35 is connected to the outlet 27, and the inlets 28 of different units are connected correspondingly. The gas supply end can provide oxygen, nitrogen, compressed air and other gases respectively. The gas outlet pipe 29 leads the corresponding gas to the patient, and a valve can be preset on the gas outlet pipe 29 to control the on-off of the gas supply.

After use, the telescopic structure 7 shrinks, and the telescopic end of the telescopic structure 7 pulls the tie rod 9, the swivel sleeve 8, and the lower half shaft 6, so that the lower half shaft 6 rotates upward around the pin between the upper half shaft 3 and the lower half shaft 6. Lift (the upper half shaft 3 and the lower half shaft 6 need to be pre-adjusted to rotate until the pin shaft is perpendicular to the tie rod 9), until the whole is lifted up, so that the occupied space can be reduced, and structures such as hooks can be added. Then, hang the pillar 14 through the hook to prevent the pillar 14 and other structures from descending under the action of gravity after being lifted up.
