Description

Technical Field

[0001] The utility model belongs to the technical field of anesthesia sprayers, and particularly relates to an anesthesia sprayer. Background Technique

[0002] Anesthesia is a reversible functional inhibition of the central nervous system and / or peripheral nervous system caused by drugs or other methods. The main feature of this inhibition is the loss of sensation, especially pain sensation; an anesthesia sprayer is a device that uses the siphon effect to turn the anesthesia liquid medicine into a mist and evenly spray it onto the anesthesia site.

[0003] In the Chinese patent with the publication number CN219595593U, an anesthesia sprayer is disclosed. In the utility model, a spreading arc plate is installed outside the installation column through an installation cylinder and a telescopic shaft. Since the telescopic shaft can be telescoped at one end of the installation cylinder and is fixed by a fixing bolt entering the fixing hole, the distance between the spreading arc plates can be changed, so that the opening angle of the oral cavity can be adjusted.

[0004] The anesthesia sprayer in the above comparative patent adjusts the fixed arc plate through the telescopic shaft. However, due to the relatively narrow structure of the human oral cavity, the actual volume of the telescopic shaft and the fixing bolt is very small. It is necessary to complete the adjustment before placing the spreading arc plate into the patient's mouth, and at the same time, additional tools are also required to adjust and install the fixing bolt, resulting in greater difficulty in actual operation of this adjustment method. Therefore, an anesthesia sprayer that can more conveniently open the patient's oral cavity is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anesthesia sprayer to solve the problems proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An anesthesia sprayer, comprising:

[0008] A bottle body and a bottle cap, the upper end of the bottle body is threadedly connected to the bottle cap;

[0009] A suction pump, which is installed in the middle of the bottle cap, and its infusion end and liquid extraction end are respectively connected with an infusion tube and a liquid extraction tube;

[0010] An oral intubation, which is installed at the other end of the infusion tube, and a atomizing nozzle is fixedly installed at its end;

[0011] The spreading component, the spreading component is sleeved on the outside of the oral intubation tube, and it includes a rubber bite plate, a support rod, an externally threaded slider and an internally threaded tube. The support rods are symmetrically fixed at both ends of one side of the rubber bite plate. The externally threaded slider is fixedly installed at one end of the support rod. Both ends of the internally threaded tube are threadedly connected to the two externally threaded sliders on the same side.

[0012] Preferably, threads with opposite helix directions are respectively arranged on both sides of the inner side surface of the internally threaded tube.

[0013] Preferably, through holes adapted to the support rods are respectively opened at both ends of the internally threaded tube.

[0014] Preferably, a tooth groove is opened at one end of the rubber bite plate away from the support rod.

[0015] Preferably, arc-shaped elastic plates are symmetrically fixed between the two rubber bite plates.

[0016] Preferably, a handle is arranged on one side of the bottle body, and an observation window is arranged on its side surface.

[0017] Preferably, an internally threaded joint is fixedly connected to one end of the infusion tube away from the suction pump, and an externally threaded joint is fixedly connected to one end of the oral intubation tube away from the atomizing nozzle.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] (1) By setting the rubber bite plate, the support rod, the externally threaded slider and the internally threaded tube in the present utility model, when using this anesthesia sprayer, the patient bites the upper and lower teeth on the two rubber bite plates, and then rotates the two internally threaded tubes to increase the distance between the two rubber bite plates, so that the opening angle of the patient's oral cavity can be quickly adjusted, enabling the atomizing nozzle and the oral intubation tube to conveniently pass through between the two rubber bite plates and be inserted into the patient's throat.

[0020] (2) By setting the arc-shaped elastic plate in the present utility model, not only can the rubber bite plate be made to fit with the patient's teeth under the elastic force of the arc-shaped elastic plate, but also the oral intubation tube can be limited, making the insertion and extraction of the oral intubation tube into and from the oral cavity more smooth, and avoiding contact between the atomizing nozzle and the oral intubation tube and the internally threaded tube.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figure, the relative dimensions and proportions of the parts shown in the figure are exaggerated or reduced in size and illustrated, and any dimensions are only exemplary and not restrictive.

[0028] Embodiment 1:

[0029] Please refer to Figure 1 - Figure 4 As shown, an anesthetic sprayer includes:

[0030] A bottle body 1 and a bottle cap 2, the upper end of the bottle body 1 is threadedly connected to the bottle cap 2;

[0031] A suction pump 3, the suction pump 3 is installed in the middle of the bottle cap 2, and its infusion end and liquid extraction end are respectively connected with an infusion tube 31 and a liquid extraction tube 32;

[0032] An oral intubation 4, the oral intubation 4 is installed at the other end of the infusion tube 31, and its end is fixedly installed with an atomizing nozzle 5;

[0033] A spreading component 6, the spreading component 6 is sleeved outside the oral intubation 4, and it includes a rubber bite plate 61, a support rod 62, an external thread slider 63 and an internal thread tube 64. The support rods 62 are symmetrically fixed at both ends of one side of the rubber bite plate 61, the external thread slider 63 is fixedly installed at one end of the support rod 62, and both ends of the internal thread tube 64 are threadedly connected to the two external thread sliders 63 on the same side.

[0034] Specifically, as can be seen from Figure 4 the two sides of the inner side surface of the internal thread tube 64 are respectively provided with threads with opposite helix directions.

[0035] Specifically, as can be seen from Figure 4It can be seen that both ends of the internal threaded tube 64 are provided with through holes adapted to the support rod 62 .

[0036] Specifically, by Figure 3 It can be seen that a tooth groove 65 is formed at one end of the rubber bite plate 61 away from the support rod 62 .

[0037] As can be seen from the above, when using this anesthesia sprayer, first put the two rubber bite plates 61 into the patient's mouth so that they are bitten by the patient's upper and lower teeth respectively. Since the external thread slider 63 is fixedly connected to the rubber bite plate 61 through the support rod 62, and the external thread slider 63 is sleeved inside the internal thread tube 64, the external thread slider 63 cannot rotate. Since the two sides of the inner side surface of the internal thread tube 64 are respectively provided with threads with opposite rotation directions, when the internal thread tube 64 is rotated, the two external thread sliders 63 threadedly connected thereto move in opposite directions, so that the two rubber bite plates 61 can be adjusted. The distance between the rubber bite plates 61 is adjusted in this way, and the operation is simpler and more convenient. The tooth grooves 65 are arranged so that the rubber bite plates 61 are not easy to fall off the patient's teeth. After the installation of the support component 6 is completed, the atomizing nozzle 5 can be directly inserted into the patient's oral cavity through the two rubber bite plates 61. Since the structure of the support component 6 is simple, it is convenient to check the moving depth of the atomizing nozzle 5, making the anesthesia sprayer more convenient to use. At the same time, it is convenient to clean and replace the oral cannula 4 and the support component 6 after use.

[0038] Specifically, by Figure 3 and Figure 4 It can be seen that an arc-shaped elastic plate 66 is symmetrically fixed between the two rubber bite plates 61 .

[0039] As can be seen from the above, by providing the arc-shaped elastic plate 66, the rubber bite plate 61 can be pushed to deform into an arc shape so that it fits the patient's teeth and is less likely to fall off. At the same time, the two arc-shaped elastic plates 66 cooperate with each other to limit the oral cannula 4, making it easier to insert the oral cannula 4 into and remove it from the oral cavity.

[0040] Embodiment 2:

[0041] refer to Figure 1 and Figure 2 As shown, a handle 11 is provided on one side of the bottle body 1, and an observation window 12 is provided on the side thereof.

[0042] As can be seen from the above, by providing the handle 11, it is convenient to lift the anesthesia sprayer, and by providing the observation window 12, it is convenient to observe the remaining amount of the anesthetic solution.

[0043] Specifically, by Figure 2 It can be seen that the end of the infusion tube 31 away from the suction pump 3 is fixedly connected to the internal threaded connector 33 , and the end of the oral cannula 4 away from the atomizing nozzle 5 is fixedly connected to the external threaded connector 41 .

[0044] As can be seen from the above, by providing the internal-threaded joint 33 and the external-threaded joint 41, it is convenient to connect and disconnect the oral intubation tube 4 and the infusion tube 31.
