Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a laryngeal anesthesia sprayer for anesthesiology. Background Art

[0002] The laryngeal anesthesia sprayers currently on the market are not only complex in structure, but also have certain defects when used. Traditional laryngeal anesthesia sprayers all use an air bag to compress the storage bottle to spray the anesthetic. When the air bag is compressed and then inflated again, the anesthetic is easily sucked back into the air bag through the trachea, causing contamination and waste of the anesthetic. In addition, ordinary laryngeal anesthesia sprayers are not provided with a structure for clamping the nozzle. When not in use, the nozzle is often leaned against the bottle body or placed on the table, which can easily cause damage or contamination to the nozzle and affect subsequent use.

[0003] The Chinese utility model patent with announcement number CN210009502U in the prior art discloses a laryngeal anesthesia sprayer for anesthesiology, comprising an anesthetic storage bottle, a movable cover being screwed on the top of the anesthetic storage bottle through a thread, and an anesthetic outlet being provided at the bottom end of the side wall of the anesthetic storage bottle, an end of the anesthetic outlet away from the anesthetic storage bottle being connected to a nozzle, an end of the nozzle away from the anesthetic outlet being provided with a spray head, a piston matching the piston being provided at the top end of the inner part of the anesthetic storage bottle, the device being provided with a piston, a piston rod and a pressing plate, when anesthesia is required for the patient's throat, medical staff can press the pressing plate downward, and then the piston rod moves downward, so that the piston squeezes the anesthetic inside the anesthetic storage bottle out of the anesthetic outlet, and the patient's throat can be anesthetized, thereby solving the problem that the conventional laryngeal anesthesia sprayer adopts an air bag to compress the storage bottle, and the anesthetic is easily sucked back into the air bag through the trachea.

[0004] When the above device is not in working state, the nozzle is fixed by a spring and a clamp. Since most nozzles are hoses, in this technology, fixing them by a spring and a clamp not only has a poor fixing effect, but also the spring force acting on the clamp can easily cause the nozzle to deform, which not only affects the circulation of the anesthetic liquid in the nozzle, but also shortens the service life of the nozzle. Summary of the invention

[0005] The purpose of the present invention is to provide a laryngeal anesthesia sprayer for anesthesiology to solve the technical problems in the above-mentioned prior art.

[0006] The invention provides a laryngeal anesthesia sprayer for anesthesia department, comprising an anesthesia bottle, a top cover, a pressure piston, a piston rod and a pressure plate, the top of the anesthesia bottle is open, the top cover is fixed to the top of the anesthesia bottle by threads, the pressure piston is slidably connected to the inside of the anesthesia bottle, the piston rod is coaxially fixed on the pressure piston, and the piston rod extends upward to penetrate the top cover, the piston rod is sealingly and slidably connected to the top cover, the pressure plate is fixed to an end of the piston rod away from the pressure piston, a liquid outlet is provided on the lower side of the anesthesia bottle, the liquid outlet is connected to a nozzle, a spray head is installed at an end of the nozzle away from the liquid outlet, a plurality of fixing components are also installed on the side wall of the anesthesia bottle, the plurality of fixing components are all on the same longitudinal axis, each fixing component comprises a fixing block and two fixing bags, a clamping slot is provided in the fixing block, two fixing bags are respectively fixed on both sides of the clamping slot, when the nozzle is located in the clamping slot, the fixing bag in the clamping slot can be clamped and fixed to the nozzle.

[0007] Furthermore, the pressure piston is located at a lowest position in the anesthesia bottle that is higher than the position of the liquid outlet.

[0008] Furthermore, the volumes of the fixing bags of the fixing components increase sequentially from bottom to top.

[0009] Furthermore, the number of the fixing components is 3-5 groups.

[0010] Furthermore, a plurality of auxiliary capsules are installed in each of the fixing capsules, each of the auxiliary capsules is a spherical capsule, and the volume of the auxiliary capsules located at both ends of the fixing capsule in the same fixing capsule is larger than the volume of the remaining auxiliary capsules.

[0011] Furthermore, the number of auxiliary capsules in each fixed capsule is 4-6.

[0012] Furthermore, the several auxiliary bags in each fixed bag are interconnected, and each fixed bag also includes a connecting tube, which passes through the fixed bag and is connected to an auxiliary bag, and one end of the connecting tube away from the auxiliary bag is connected to the air pump.

[0013] Furthermore, the fixing capsule is filled with a non-Newtonian fluid.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The present invention fixes the nozzle by means of several groups of fixing components, and realizes the clamping fixation of the nozzle by means of two fixing bags. Due to the uniform contact between the fixing bags and the nozzle, excessive local pressure on the nozzle is prevented, which causes the nozzle to be squeezed and deformed, thereby avoiding the subsequent unsmooth flow of the anesthetic liquid in the nozzle and prolonging the service life of the nozzle;

[0016] (2) The volumes of the fixing bags of the fixing components of the present invention increase from bottom to top, so that when medical staff fix the nozzle, the fixing components at the lower position can be easily engaged with the nozzle, and the fixing components at the upper position can be more firmly engaged with the nozzle. Under the premise of keeping the nozzle fixed more stably, the difficulty of fixing the nozzle is reduced, thereby reducing the work intensity of medical staff.

[0017] (3) The present invention arranges the auxiliary bag in the fixed bag so that the fixed bag can be expanded by the expansion of the auxiliary bag. This not only facilitates the adjustment of the expansion degree of the fixed bags in each group of fixed components to adapt to nozzles of different diameters, but also makes the engagement with the nozzle more stable and the contact pressure with the nozzle more uniform according to the different volumes of the multiple auxiliary bags in the fixed bag, thereby further preventing the nozzle from being deformed and extending the service life of the nozzle.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Combine the following Figures 1 to 5As shown, an embodiment of the present invention provides a laryngeal anesthesia sprayer for anesthesiology, comprising an anesthesia bottle 100, a top cover 110, a pressure piston 120, a piston rod 130 and a pressing plate 140, wherein the top of the anesthesia bottle 100 is open, the top cover 110 is fixed to the top of the anesthesia bottle 100 by threads, the pressure piston 120 is slidably connected inside the anesthesia bottle 100, the piston rod 130 is coaxially fixed on the pressure piston 120, and the piston rod 130 extends upward through the top cover 110, the piston rod 130 is sealingly and slidably connected to the top cover 110, the pressing plate 140 is fixed to one end of the piston rod 130 away from the pressure piston 120, and the anesthesia bottle 1 A liquid outlet 150 is provided at the lower side of the anesthesia bottle 100, and the liquid outlet 150 is connected to a nozzle 160, and a spray head 170 is installed at one end of the nozzle 160 away from the liquid outlet 150. A plurality of fixing components 200 are also installed on the side wall of the anesthesia bottle 100, and the plurality of fixing components 200 are all located on the same longitudinal axis. Each fixing component 200 includes a fixing block 210 and two fixing capsules 230. A slot 220 is provided in the fixing block 210, and two fixing capsules 230 are respectively fixed on both sides of the slot 220. When the nozzle 160 is located in the slot 220, the nozzle 160 can be fixed by the fixing capsule 230 in the slot 220.

[0032] When performing anesthetic spraying, the medical staff first opens the top cover 110, replenishes the anesthetic solution in the anesthetic bottle 100, then installs the top cover 110, and then takes out the nozzle 160 from the fixing component 200, so that the spray head 170 is aimed at the patient's anesthesia position, and finally presses the pressing plate 140. The pressing plate 140 drives the pressure piston 120 to move downward through the piston rod 130, squeezes the anesthetic solution in the anesthetic bottle 100 into the nozzle 160, and finally sprays it out through the spray head 170 to achieve anesthetic spraying. After the operation is completed, the nozzle 160 is fixed by several groups of fixing components 200, and the nozzle 160 is clamped and fixed by two fixing bags 230. Due to the uniform contact between the fixing bag 230 and the nozzle 160, the local pressure on the nozzle 160 is prevented from being too large, so that the nozzle 160 is squeezed and deformed, thereby avoiding the subsequent anesthetic solution from flowing unsmoothly in the nozzle 160 and extending the service life of the nozzle 160.

[0033] Preferably, the pressure piston 120 is located at the lowest position in the anesthesia bottle 100 and is higher than the position of the liquid outlet 150 .

[0034] Preferably, the volumes of the fixing bags 230 of the fixing components 200 increase from bottom to top, so that when the medical staff fix the nozzle 160, the fixing components 200 at a lower position can be engaged with the nozzle 160 more easily, and the fixing components 200 at a higher position can be engaged with the nozzle 160 more firmly. On the premise of keeping the nozzle 160 relatively stable as a whole, the difficulty of fixing the nozzle 160 is reduced, thereby reducing the work intensity of the medical staff.

[0035] Preferably, the number of the fixing components 200 is 3-5 groups.

[0036] Preferably, a plurality of auxiliary capsules 240 are installed in each of the fixing capsules 230 , each of the auxiliary capsules 240 is a spherical capsule, and the volume of the auxiliary capsules 240 located at both ends of the fixing capsule 230 in the same fixing capsule 230 is greater than the volume of the remaining auxiliary capsules 240 .

[0037] Preferably, the number of auxiliary capsules 240 in each fixing capsule 230 is 4-6.

[0038] Preferably, the several auxiliary bags 240 in each fixed bag 230 are interconnected, and each fixed bag 230 also includes a connecting tube 250, which passes through the fixed bag 230 and is connected to an auxiliary bag 240, and the end of the connecting tube 250 away from the auxiliary bag 240 is connected to an air pump (not shown in the figure). By setting the auxiliary bag 240 in the fixed bag 230, the fixed bag 230 can be expanded by the expansion of the auxiliary bag 240, which is not only convenient for adjusting the expansion degree of the fixed bag 230 in each group of fixed components 200 to adapt to nozzles 160 of different diameters, but also according to the different volumes of the multiple auxiliary bags 240 in the fixed bag 230, the engagement with the nozzle 160 is more stable, and the contact pressure with the nozzle 160 is more uniform, which further prevents the nozzle 160 from deformation and extends the service life of the nozzle 160.

[0039] Preferably, the fixing capsule 230 is filled with a non-Newtonian fluid, so that the fixing effect of the fixing capsule 230 on the nozzle 160 is more stable.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
