Description

Technical Field

[0001] The present application relates to the technical field of spraying, and in particular to a spraying device. Background Art

[0002] Anesthesia is a comprehensive subject that includes knowledge from multiple disciplines. It covers a wide range, not only meeting the requirements of surgery, but also involving rescue work in various departments, painless delivery in gynecology, painless abortion, etc.

[0003] In the clinical medical process, when performing laryngoscopy and laryngeal surgery, in order to relieve the patient's pain and facilitate the doctor's work, it is necessary to use the anesthesia department's sprayer to perform local anesthesia on the laryngeal nerves. Anesthetic spray is widely used in throat surgery and endoscopic examination. In these works, anesthetic drugs need to be sprayed. Common spray devices have only one nozzle and cannot be replaced according to needs. Since there are many patients in the hospital, cross infection is easily caused by multiple people using it, which increases the workload of medical staff and has poor practicality. Therefore, a spray device is needed to improve the above problems. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present application provides a spray device having the following beneficial effects:

[0016] The spray device slides the second connecting tube into the first connecting tube and presses the connecting plate downward, so that the sliding rod drives the fixing plate and the clamping block to move downward, so that the sliding rod passes through the sliding groove. At this time, the two springs perform compression operation, loosen the connecting plate, and the sliding rod, the fixing plate and the clamping block are reset by the elastic force of the two springs themselves, so that the clamping block and the clamping groove are clamped, thereby completing the connection operation of the first connecting tube and the second connecting tube. By rotating the second bolt, the first connecting tube and the second connecting tube are connected more tightly, and the sliding rod is limited by the two limiting mechanisms to prevent accidental contact with the sliding rod. When the nozzle needs to be replaced, the limiting operation of the limiting mechanism and the second bolt on the second connecting tube is released, and the connecting plate is pressed downward, so that the sliding rod drives the clamping block to move downward, so that the clamping block is separated from the clamping groove, and the second connecting tube is taken out for replacement, thereby realizing the replacement operation of the nozzle, avoiding cross infection, and having high practicality.

[0025] See also Figure 1 and Figure 2 A spray device includes a medicine liquid bottle 1 and a second connecting tube 5, the second connecting tube 5 is provided with a nozzle 6, the medicine liquid bottle 1 is provided with a connecting port 2, the connecting port 2 is connected and connected with a mounting plate 3, the mounting plate 3 is fixedly installed with a first connecting tube 4, the first connecting tube 4 is provided with a second bolt 21, and the first connecting tube 4 is slidably connected to the second connecting tube 5.

[0026] See also Figure 1-5The first connecting tube 4 and the second connecting tube 5 are connected by a connecting mechanism, which includes a sliding rod 7. A sliding hole is provided on the first connecting tube 4. The sliding rod 7 is slidably connected to the sliding hole. A connecting plate 8 is fixedly installed on the sliding rod 7. Two telescopic columns 9 are symmetrically fixedly installed on the bottom end of the connecting plate 8. Springs 10 are mounted on the two telescopic columns 9. The two ends of each spring 10 are respectively fixedly connected to the first connecting tube 4 and the connecting plate 8. A card slot 13 and a slide slot 14 are provided on the second connecting tube 5. The sliding rod 7 passes through the slide slot 14. A fixed plate 11 is fixedly installed on the bottom end of the sliding rod 7. A card block 12 is fixedly installed on the fixed plate 11. The card block 12 is clamped with the card slot 13. The second connecting tube 5 is slid into the first connecting tube 4, and the connecting plate 8 is pressed downward, so that the sliding rod 7 drives the fixed plate 11 and the card block 12 to move downward, so that the sliding rod 7 passes through the slide groove 14, at which time the two springs 10 perform a compression operation, loosen the connecting plate 8, and the elastic force of the two springs 10 drives the slide bar 7, the fixing plate 11 and the block 12 to reset, so that the block 12 and the slot 13 perform a clamping operation, thereby completing the connection operation of the first connecting pipe 4 and the second connecting pipe 5, and by rotating the second bolt 21, the first connecting pipe 4 and the second connecting pipe 5 are connected more tightly, and the slide bar 7 is limited by the two limiting mechanisms to prevent accidental contact with the slide bar 7. When the nozzle 6 needs to be replaced, the limiting operation of the limiting mechanism and the second bolt 21 on the second connecting pipe 5 is released, and the connecting plate 8 is pressed downward, so that the slide bar 7 drives the block 12 to move downward, so that the block 12 is disengaged from the slot 13, and the second connecting pipe 5 is taken out for replacement, thereby realizing the replacement operation of the nozzle 6.

[0027] See also Figure 3 and Figure 4 The slide bar 7 is limited by two limiting mechanisms, one of which includes a fixed column 15, which is fixedly mounted at the bottom end of the connecting plate 8, and a sliding column 16 is slidably mounted in the fixed column 15. One end of the sliding column 16 away from the fixed column 15 is fixedly connected to the first connecting pipe 4. Limiting holes are provided on the fixed column 15 and the sliding column 16, and a first bolt 17 is slidably mounted in the limiting hole. When the clamping block 12 and the clamping groove 13 are clamped, the two fixed columns 15 and the two sliding columns 16 are limited by the two first bolts 17, thereby limiting the slide bar 7, thereby making the connection between the first connecting pipe 4 and the second connecting pipe 5 more stable.

[0028] See also Figure 2 A rubber pad 18 is provided on the inner wall of the first connecting pipe 4, and the sealing performance is improved by the provision of the rubber pad 18.

[0029] See also Figure 1 It should also be noted that an observation window 19 is connected to the medicine liquid bottle 1 and provided with scale lines. The installation of the observation window 19 facilitates observation of the capacity inside the medicine liquid bottle 1 .

[0030] See also Figure 3 and Figure 4 The connecting plate 8 is provided with anti-skid patterns 20, and the friction force is increased by the provision of the anti-skid patterns 20.

[0031] In summary, when the spray device is in use, add liquid medicine into the liquid medicine bottle 1, observe the capacity of the liquid medicine bottle 1 through the observation window 19 and the scale line, slide the second connecting tube 5 into the first connecting tube 4, press the connecting plate 8 downward, so that the slide bar 7 drives the fixed plate 11 and the card block 12 to move downward, and the slide bar 7 passes through the slide groove 14. At this time, the two springs 10 perform a compression operation, release the connecting plate 8, and drive the slide bar 7, the fixed plate 11 and the card block 12 to reset through the elastic force of the two springs 10 themselves, so that the card block 12 and the card groove 13 are engaged, thereby completing the connection operation of the first connecting tube 4 and the second connecting tube 5. By rotating the second bolt 21, the first connecting pipe 4 and the second connecting pipe 5 are connected more tightly, and the two first bolts 17 are used to limit the two fixed columns 15 and the two sliding columns 16, thereby limiting the slide rod 7 to prevent accidental contact with the slide rod 7. When the nozzle 6 needs to be replaced, the limiting operation of the two first bolts 17 on the two fixed columns 15 and the two sliding columns 16 is released, and the limiting operation of the second bolt 21 on the second connecting pipe 5 is released, and the connecting plate 8 is pressed downward to make the slide rod 7 drive the block 12 to move downward, so that the block 12 is disengaged from the slot 13, and the second connecting pipe 5 and the nozzle 6 are taken out for replacement.
