Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable flow anesthetic spray device. Background Technology

[0002] In the field of medical device technology, anesthetic spray devices are commonly used in clinical anesthesia and pain management. They achieve local or general anesthesia by atomizing anesthetic fluid and spraying it onto the treatment site. However, existing anesthetic spray devices have the following shortcomings in practical applications: First, existing devices typically only have a single anesthetic solution storage structure. However, some patients have allergic reactions to certain components of common anesthetics, making it difficult to flexibly mix anesthetic solutions with different components according to the patient's specific condition or anesthetic needs. Furthermore, the lack of an efficient mixing mechanism leads to uneven mixing of the anesthetic solution, affecting the stability and consistency of the anesthetic effect. Second, in terms of flow control, traditional devices mostly use simple valve adjustments, resulting in low flow control precision. This cannot meet the precise control requirements for anesthetic dosage in different surgical or treatment scenarios. At the same time, the adjustment process is cumbersome and not conducive to rapid clinical operation.

[0003] In addition, the height adjustment structure of existing anesthetic spray devices is relatively simple, relying mostly on manual knobs or fixed brackets. It is difficult to make quick and accurate height adjustments according to the patient's position or the operating habits of medical staff, which affects the convenience of operation. At the same time, the device has poor mobility and lacks flexible movement and locking mechanisms, which is inconvenient when used in clinical transport or in multiple scenarios.

[0004] To address the aforementioned problems, this invention proposes an adjustable flow anesthetic spray device. Summary of the Invention

[0005] To address the problems in the existing technology, the present invention provides an adjustable flow anesthetic spray device, which solves the problems of inaccurate flow adjustment, poor anesthetic solution mixing effect, inconvenient device height adjustment, and insufficient mobility.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: an adjustable flow anesthetic spray device, including a support plate, the upper end of which is fixedly connected to a first storage tank and a second storage tank filled with different anesthetic liquids via a bracket, and a feed pipe is fixedly connected to one side of each of the first and second storage tanks. A peristaltic pump is fixedly connected to the upper end of the support plate via a bracket, and a U-shaped pipe with a valve at the upper end is fixedly connected to the input end of the peristaltic pump. The upper end of the U-shaped pipe is connected to the first and second storage tanks respectively. A drive motor is fixedly connected to the upper end of the first storage tank via a bracket, and a first rotating rod is fixedly connected to the output end of the drive motor. The first rotating rod is rotatably connected to the inside of the first storage tank via a bearing, and a first transmission wheel is fixedly connected to the upper wall of the first rotating rod. The second storage tank is rotatably connected to a second rotating rod via a bearing, and a second transmission wheel is fixedly connected to the upper end of the second rotating rod. The second transmission wheel and the first transmission wheel are connected to a belt for transmission. A symmetrically arranged mixing plate is fixedly connected to the lower ends of both the first and second rotating rods. A first scraper that abuts against the inner walls of the first and second storage tanks is fixedly connected to both sides of the mixing plate, and a second scraper is fixedly connected to the lower end of each mixing plate via a bracket.

[0007] Specifically, the peristaltic pump output pipe is fixedly connected to the first connecting pipe via an adapter. The upper inner wall of the first connecting pipe is rotatably connected to the drive rod via a bracket and a bearing. The upper end of the drive rod is fixedly connected to symmetrically arranged drive fan blades. The lower end of the drive rod is fixedly connected to a symmetrically arranged hybrid rod. The bottom end of the drive rod is fixedly connected to a fixed rod. The outer wall of the fixed rod is fixedly connected to a threaded fan blade.

[0008] Specifically, a plurality of spray holes are formed through one side of the lower end of the first connecting pipe. A first annular groove is formed on the outer wall of the first connecting pipe above the spray holes. A first slider is slidably connected to both sides of the first annular groove. The opposite sides of the first slider are fixedly connected to a rotating pipe with sealing rings at both ends. A sealing sheet is fixedly connected to the inner wall of one side of the upper end of the rotating pipe. The sealing sheet is positioned corresponding to the spray holes. A second connecting pipe is sleeved on the lower end of the rotating pipe. A second annular groove is formed on the outer wall of the upper end of the second connecting pipe. A second slider is slidably connected to both sides of the second annular groove. The opposite side of the second slider is fixedly connected to the inner wall of the rotating pipe.

[0009] Specifically, a corrugated telescopic tube is fixedly connected to the lower end of the second connecting tube, and an atomizing spray mask is fixedly connected to the output end of the corrugated telescopic tube. A valve is installed on the lower end wall of the corrugated telescopic tube.

[0010] Specifically, one side of the support plate is connected to a screw rod via a bracket thread. The lower end of the screw rod is rotatably connected to the base plate via a bearing. The upper end of the screw rod is fixedly connected to a stepper motor with an automatic locking structure. The upper end of the stepper motor is fixedly connected to an L-shaped plate. The lower end of the L-shaped plate is fixedly connected to the base plate. A sliding groove is opened on the L-shaped plate. A sliding plate is slidably connected in the sliding groove.

[0011] Specifically, the discharge pipe openings of both the first and second storage boxes are filled with butyl rubber.

[0012] Specifically, self-locking casters are fixedly connected to both corners of the lower end of the base plate.

[0013] The beneficial effects of this invention are: (1) The adjustable flow anesthetic spray device of the present invention stores different anesthetic liquids through a first storage box and a second storage box respectively. The drive motor drives the rotating rod, mixing plate and scraper to dynamically stir the liquid.

(2) The adjustable flow anesthetic spray device of the present invention has a peristaltic pump that can precisely control the flow rate of the drug solution. With the spray hole on the first connecting pipe and the sealing plate structure of the rotating pipe, the coverage area of ​​the sealing plate on the spray hole can be adjusted by rotating the rotating pipe, so as to achieve stepless and precise adjustment of the spray flow rate, solve the problem of insufficient adjustment accuracy of traditional valves, and adapt to the dosage control requirements of different surgical scenarios. (3) The adjustable flow anesthetic spray device of the present invention uses a stepper motor to drive the support plate to move up and down through a screw. The L-shaped plate and the sliding groove structure of the slide plate enable precise adjustment of the device height. The self-locking universal wheels at the bottom of the base plate support the device to move flexibly and lock in position, which makes it easy to adjust the position of the device according to the patient's position or the operating habits of medical staff, thereby improving the convenience and stability of clinical use.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-8 As shown, the present invention provides the following technical solution: Example 1: An adjustable flow anesthetic spray device includes a support plate 1. A screw 31 is threadedly connected to one side of the support plate 1 via a bracket. The lower end of the screw 31 is rotatably connected to a base plate 32 via a bearing. A stepper motor 33 with an automatic locking structure is fixedly connected to the upper end of the screw 31. An L-shaped plate 34 is fixedly connected to the upper end of the stepper motor 33. The lower end of the L-shaped plate 34 is fixedly connected to the base plate 32. A sliding groove 35 is provided on the L-shaped plate 34. A sliding plate 36 is slidably connected in the sliding groove 35. The sliding plate 36 is threadedly connected to the wall of the screw 31. Self-locking casters are fixedly connected to both corners of the lower end of the base plate 32.

[0019] In use, unlock the self-locking casters at the bottom of the base plate 32, push the device to the target position, and then step on the locking pedal of the casters to complete the positioning. The base plate 32 is connected to the support plate 1 through the screw 31. The L-shaped plate 34 is fixed to the base plate 32. The slide plate 36 in the slide groove 35 is threadedly engaged with the screw 31. Start the stepper motor 33 (with its own automatic locking structure). The motor drives the screw 31 to rotate, causing the slide plate 36 to slide up and down in the slide groove 35, thereby realizing the synchronous adjustment of the height of the support plate 1 and the upper components. After adjusting to the required height, the stepper motor 33 automatically locks the screw 31 to prevent the device from shaking.

[0020] Example 2: This example differs from Example 1 in that the upper end of the support plate 1 is fixedly connected to a first storage tank 2 and a second storage tank 3, which are filled with different anesthetic solutions, via a bracket. A feed pipe is fixedly connected to one side of both the first and second storage tanks 2 and 3. The openings of the feed pipes of both the first and second storage tanks 2 and 3 are filled with butyl rubber. A peristaltic pump 4 is fixedly connected to the upper end of the support plate 1 via a bracket. The input end of the peristaltic pump 4 is fixedly connected to a U-shaped pipe 5 with a valve at its upper end. The upper end of the U-shaped pipe 5 is connected to both the first and second storage tanks 2 and 3, respectively. A drive motor 6 is fixedly connected to the upper end of the first storage tank 2 via a bracket. The drive motor 6 outputs... The first rotating rod 7 is fixedly connected to the first storage box 2 via a bearing. The first rotating rod 7 is rotatably connected to the first storage box 2 via a bearing. The upper end of the first rotating rod 7 is fixedly connected to the first transmission wheel 8. The second storage box 3 is rotatably connected to the second rotating rod 9 via a bearing. The upper end of the second rotating rod 9 is fixedly connected to the second transmission wheel 10. The second transmission wheel 10 and the first transmission wheel 8 are connected to the belt 11 for transmission. The lower ends of the first rotating rod 7 and the second rotating rod 9 are both fixedly connected to the mixing plates 12, which are symmetrically arranged. The two sides of the mixing plates 12 are both fixedly connected to the first scraper 13, which abuts against the inner walls of the first storage box 2 and the second storage box 3. The lower ends of the mixing plates 12 are both fixedly connected to the second scraper 14 via a bracket.

[0021] In use, anesthetic solutions of different compositions are injected into the feeding tubes of the first storage tank 2 and the second storage tank 3 through needles. The butyl rubber at the opening of the feeding tube prevents leakage or evaporation of the solution. At this time, the drive motor 6 is started by an external power supply. The first rotating rod 7 at the output end of the drive motor 6 rotates in the first storage tank 2 through the bearing. The first transmission wheel 8 drives the second transmission wheel 10 through the belt 11, so that the second rotating rod 9 rotates synchronously in the second storage tank 3. The mixing plate 12 at the lower end of the first rotating rod 7 and the second rotating rod 9 rotates with the rotating rod to stir the solution. The first scraper 13 abuts against the inner wall of the storage tank to prevent the solution from adhering or settling. The second scraper 14 scrapes off the residual solution at the bottom of the storage tank to ensure uniform mixing. After the peristaltic pump 4 is started, the valve is controlled according to actual needs, so that the solution is extracted from the first storage tank 2 and the second storage tank 3 through the U-shaped tube 5 for use.

[0022] Example 3: The technical solution of this example, which differs from Example 2, includes: the peristaltic pump 4 output pipe is fixedly connected to the first connecting pipe 15 via an adapter; the upper inner wall of the first connecting pipe 15 is rotatably connected to the drive rod 16 via a bracket and bearing; the upper end of the drive rod 16 is fixedly connected to symmetrically arranged drive fan blades 17; the lower end of the drive rod 16 is fixedly connected to symmetrically arranged hybrid rods 18; and the bottom end of the drive rod 16 is fixedly connected to a fixing rod 19; the outer wall of the fixing rod 19 is fixedly connected to threaded fan blades 20; several spray holes 21 are opened through one side of the lower end of the first connecting pipe 15; a first annular groove 22 is opened on the outer wall of the first connecting pipe 15 above the spray holes 21; and both sides of the first annular groove 22 are slidable. The first slider 23 is dynamically connected, and the first slider 23 is fixedly connected to the rotating tube 24 with sealing rings at both ends on the opposite side. The inner wall of the upper end of the rotating tube 24 is fixedly connected to the sealing plate 25, and the sealing plate 25 and the spray hole 21 are positioned correspondingly. The lower end of the rotating tube 24 is sleeved with the second connecting tube 26. The upper outer wall of the second connecting tube 26 has a second annular groove 27. The second annular groove 27 is slidably connected to the second slider 28 on both sides. The opposite side of the second slider 28 is fixedly connected to the inner wall of the rotating tube 24. The lower end of the second connecting tube 26 is fixedly connected to the corrugated telescopic tube 29. The output end of the corrugated telescopic tube 29 is fixedly connected to the atomizing spray mask 30, and a valve is installed on the lower end of the corrugated telescopic tube 29.

[0023] In use, when the liquid medicine output by the peristaltic pump 4 flows through the first connecting pipe 15, the driving fan blade 17 is driven to rotate by the water flow, which in turn drives the mixing rod 18 at the lower end of the driving rod 16 and the threaded fan blade 20 to rotate, thus performing secondary stirring of the liquid medicine and enhancing the uniformity of atomization. When the flow rate needs to be adjusted, the rotating pipe 24 is rotated. When the rotating pipe 24 rotates, it drives the sealing plate 25 to rotate. At the same time, the force on the rotating pipe 24 will cause it to slide through the first slider 23 in the first annular groove 22, and the second slider 28 will rotate in the second annular groove 27, so that the sealing plate 25 covers the liquid medicine. The relative position of the nozzle 21 and the sealing plate 25 to the nozzle 21 determines the open area of ​​the nozzle 21: the flow rate is zero when fully covered, and the flow rate increases as the open area increases when partially covered, achieving stepless precise adjustment. After adjusting to the appropriate flow rate, the liquid medicine enters the second connecting pipe 26 through the nozzle 21, and is delivered to the atomizing spray mask 30 through the corrugated telescopic pipe 29. The valve at the lower end of the corrugated telescopic pipe 29 can control the spray on and off. The atomizing spray mask 30 fits the patient's target area (such as the oral cavity or nasal cavity) to achieve atomized spraying of the anesthetic liquid.
