Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a painless bronchofiberscope anesthesia pipeline regulating device. Background Art

[0002] Fiberoptic bronchoscopy and treatment require insertion of a bronchoscope into the patient's trachea and bronchi, which is extremely irritating and painful without anesthesia. Painless fiberoptic bronchoscopy relieves this pain and is increasingly in demand. Current fiberoptic bronchoscopy anesthesia circuit regulators typically directly inject anesthetics, which enter the body directly without controlled flow or slow entry.

[0003] Chinese patent CN211093961U discloses a painless bronchoscopic anesthesia circuit regulator that facilitates control of the flow of anesthetic fluid via a flow control valve. However, this control method presents the following problems: existing valves typically control flow by the size of the gap opened by the valve ball. However, the valve ball is a sphere, and the speed at which the size of the opening changes first increases and then decreases, resulting in unstable flow control and an inability to uniformly change the flow rate, causing discomfort to the patient.

[0004] Chinese patent CN213787299U discloses a painless bronchoscopic anesthesia pipeline regulating device, which is provided with an air storage bin, a through hole is provided in the middle of the air storage bin, and a shrink hose is fixedly connected to the inner wall of the through hole, and the user adjusts the flow rate by adjusting the diameter of the shrink hose. However, in the process of adjusting the flow rate, this patent requires a manual airbag pump to pump air into the air storage bin, increasing the air pressure in the air storage bin so that the middle concave part of the shrink hose shrinks toward the center, reducing the diameter and reducing the flow rate; and releasing the pressure by opening the air relief valve, so that the diameter of the shrink hose increases and the flow rate increases. This control method has the following problems during use: increasing and decreasing the flow rate requires two sets of regulating devices, the flow rate cannot be changed flexibly and quickly, and the adjustment process requires multiple operations, which prolongs the operation time and is not conducive to the operation.

[0005] Therefore, it is necessary to design a painless bronchoscopic anesthesia pipeline adjustment device, which can increase and decrease the flow rate through a set of adjustment devices. Utility Model Content

[0006] The purpose of the present invention is to provide a painless bronchoscopic anesthesia pipeline adjustment device to overcome the defects in the prior art, solve the problems raised in the above-mentioned background technology, and realize the control of the flow of anesthetic drugs entering the patient's body with flexible and simple operation.

[0007] In order to solve the above problems, the technical solution of the utility model is:

[0008] A painless bronchoscopic anesthesia pipeline adjustment device includes a shell and a pressure wheel. The pressure wheel is arranged in the shell, and slide grooves are provided on both sides of the shell. The bottom surface of the shell is an inclined surface. The rotating shafts arranged on both sides of the pressure wheel are assembled in the slide grooves, and a wheel position sensing part is provided in the slide grooves.

[0009] The wheel position sensing part includes a plurality of pairs of arc-shaped ridges arranged at the bottom of the chute, each pair of ridges is arranged in sequence at the same interval, and notches are provided on the outer shell at both ends of the top surface of the chute.

[0010] The wheel position sensing part includes an opening on the bottom surface of the slide groove and two insertion holes on the outer shell. A top strip is provided in the opening, and a plurality of pairs of arc-shaped protrusions are provided on the surface of the top strip. Each pair of arc-shaped protrusions is arranged in sequence according to the same spacing. The two ends of the top strip are connected to the mounting block through an arc-shaped elastic strip. A plug rod is fixed on the mounting block, and the plug rod is inserted into the insertion hole.

[0011] The top strip, the arc-shaped protrusion, the arc-shaped elastic strip, the mounting block and the inserting rod are integrally injection-molded by plastic.

[0012] Scale lines are provided on the outer shell.

[0013] The beneficial effects of the utility model are:

[0014] 1. In the present invention, the degree of squeezing of the hose is changed by changing the position of the pressing wheel in the chute, thereby achieving control and adjustment of the flow rate of the anesthetic. The entire adjustment process only requires rolling the pressing wheel, which is easy to operate.

[0015] 2. The wheel position sensing part enables the user to clearly feel the sliding resistance, at which time the user can realize that the liquid flow rate has reached a certain set value; during use, the user can directly adjust to the appropriate scale line position according to the required liquid flow rate, and can judge whether the target position has been reached based on the number of times resistance is received when being pushed, thereby reducing errors caused by visual inspection, simplifying operating steps, and improving operating accuracy.

[0022] A painless bronchoscopic anesthesia pipeline adjustment device includes a shell 1 and a pressure wheel 4, the pressure wheel 4 is arranged in the shell 1, and slide grooves 2 are provided on both sides of the shell 1. The bottom surface of the shell 1 is an inclined surface, and the rotating shafts arranged on both sides of the pressure wheel 4 are assembled in the slide groove 2. A wheel position sensing part is provided in the slide groove 2. The hose for conveying anesthetics passes through the shell 1, and the pressure wheel 4 presses the hose on the bottom surface of the shell 1. By rolling the pressure wheel 4, the anesthetic flow through the hose is regulated. In addition, the wheel position sensing part allows the user to sense the position of the pressure wheel 4 by hand to determine whether the target position has been reached, thereby reducing errors caused by visual inspection. At the same time, the sensing part can limit the rotating shaft 6 to prevent it from causing the pressure wheel 4 to be displaced due to the movement of the hose, which ultimately leads to a sudden change in the anesthetic flow.

[0023] The structure of the sensing part is as shown in the following embodiment 1 and embodiment 2:

[0024] Example 1: Figure 1 and 2 As shown, the wheel position sensing portion comprises multiple pairs of curved ridges 3 disposed at the bottom of the chute 2. Each pair of curved ridges 3 is arranged sequentially at equal spacing. Notches 5 are provided in the housing 1 at both ends of the top surface of the chute 2. When the user pushes the pressure wheel 4, the axles at both ends of the pressure wheel 4 are able to pass over the curved ridges 3 and fit between the pair of curved ridges 3. During this process, the user can sense a noticeable resistance to pushing and realize that the anesthetic flow rate has reached a preset value. Furthermore, the notches 5 are provided to provide a certain degree of elasticity to the top surface of the chute 2, ensuring that the rotating shaft can pass over the curved ridges 3.

[0025] Example 2: Figure 3 and 4 As shown, the wheel position sensing portion includes an opening formed on the bottom surface of the chute 2 and two insertion holes formed on the housing 1. A top strip 8 is provided in the opening, and a plurality of pairs of arc-shaped protrusions 9 are provided on the surface of the top strip 8. Each pair of arc-shaped protrusions 9 is arranged in sequence at the same intervals. The two ends of the top strip 8 are connected to the mounting block 11 through an arc-shaped elastic strip 10. A plug rod is fixed on the mounting block 11, and the plug rod is inserted into the insertion hole. When the user pushes the pressure wheel 4, the axles at both ends of the pressure wheel 4 roll on the top strip 8. When the axle passes over the arc-shaped protrusion 9, the arc-shaped elastic strip 10 is deformed by the rotating shaft and immediately rebounds to push the top strip 8 against the axle, allowing the axle to accurately fall between the pair of arc-shaped protrusions 9, so that the user can feel the obvious pushing resistance and realize that the anesthetic agent flow rate has reached the preset value.

[0026] The top strip 8, the arc-shaped protrusion 9, the arc-shaped elastic strip 10, the mounting block 11 and the insertion rod are integrally injection-molded by plastics, which facilitates processing and manufacturing.

[0027] Scale lines 7 are provided on the housing 1. Each scale line 7 corresponds to each pair of arcuate ridges 3 or arcuate protrusions 9, and is used to indicate the flow rate of the anesthetic agent, making it easier to observe and confirm, and further reducing errors caused by visual observation.

[0028] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
