Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a local anesthesia sprayer. Background Art

[0002] The working principle of an anesthesia nebulizer is primarily to increase the internal pressure of the liquid anesthetic, causing it to be ejected through a nozzle and form a mist. Specifically, the nebulizer usually includes a pressure tank or pump to pressurize the liquid anesthetic. When the pressure reaches a certain level, the liquid anesthetic is ejected through the small orifice of the nozzle. Due to the special design of the nozzle, the liquid is subjected to shear and centrifugal forces during ejection, breaking it into tiny droplets and forming a mist. These tiny droplets can evenly adhere to the area requiring anesthesia, achieving the effect of local anesthesia.

[0003] In the prior art, a utility model patent document with publication number CN201333240Y has been proposed. The technical solution disclosed in this patent document is as follows: This utility model provides a laryngeal local anesthetic sprayer, belonging to the field of medical device technology. Its structure is that one end of a conduit tube in an anesthetic reservoir is disposed at the bottom of the anesthetic reservoir, and the other end is connected to a nozzle via a connecting hub disposed on the anesthetic reservoir mouth. The front end of the nozzle is connected to a spray head. An trachea passes through one end of the connecting hub and is disposed in the anesthetic reservoir mouth. The other end of the trachea is connected to a blood pressure meter airbag. A spring plate is disposed on the connecting hub. The tail of the blood pressure meter airbag and the tail of the spring plate are connected by a hoop. The bottom of the anesthetic reservoir is provided with external threads. A support cap is threadedly connected to the bottom of the anesthetic reservoir, and a handle is fixedly connected to the lower part of the support cap. The front end of the nozzle is curved. This laryngeal local anesthetic sprayer facilitates multi-directional adjustment and enhances stability in use. It has a simple structure, is easy to use, and has excellent operational stability, which helps to improve work efficiency and enhance medical quality.

[0004] According to the technical solution proposed in the above utility model patent document, it can be seen that the above solution still has obvious shortcomings. For example, when using the laryngeal local anesthetic sprayer in the above technical solution for anesthesia, in order to ensure the stability of the patient's physical state, the patient often lies on his back on a chair. When the doctor holds the above instrument for anesthesia, he needs to cooperate with the lying patient to tilt the instrument so that the catheter can penetrate into the patient's laryngeal cavity. During the tilting of the instrument, the liquid level of the anesthetic liquid in the anesthetic storage bottle tilts, resulting in the bottom of the catheter in the anesthetic storage bottle not being able to always be located in the anesthetic liquid, so that the catheter will directly extract the air in the anesthetic storage bottle and spray the air into the patient's laryngeal cavity, which not only reduces the overall anesthesia efficiency, but also the sprayed air can easily cause certain damage to the patient's laryngeal cavity, making the patient's condition worse. Therefore, the existing technology urgently needs a technical solution to solve the above problems. Utility Model Content

[0023] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0024] Example

[0025] like Figures 1 to 5 As shown, the utility model provides a local anesthesia sprayer, including a liquid storage bottle 1, a connector 2 is threadedly connected to the top of the liquid storage bottle 1, a rotating connection component 3 for transporting the anesthetic liquid in the liquid storage bottle 1 is provided in the liquid storage bottle 1, and the top of the rotating connection component 3 is connected to the connector 2, one end of the connector 2 is connected to an air blowing component 4 for providing an air source, and the other end of the connector 2 is connected to a spraying component 5 for transporting the anesthetic liquid to the affected area, the air blowing component 4 is connected to the liquid storage bottle 1, and the spraying component 5 is connected to the rotating connection component 3.

[0026] The rotating connection assembly 3 includes a connecting tube 31 fixedly mounted on the bottom of the connector 2, a receiving tube 32 fixedly connected to the inside of the connecting tube 31, a bypass hole 321 for the passage of anesthetic liquid is opened at the bottom of the receiving tube 32, two limiting ring plates 33 are fixedly mounted on the outside of the bottom of the receiving tube 32, and the outside of the two limiting ring plates 33 are rotatably connected to the same connecting sleeve 34, a plastic tube 35 is fixedly connected to one side of the connecting sleeve 34, and the plastic tube 35 is connected to the connecting tube 31 through the bypass hole 321.

[0027] As a further illustration of this embodiment, when using an existing laryngeal local anesthetic sprayer for anesthesia, in order to ensure the stability of the patient's physical state, the patient usually lies on his back on a chair. During the process of anesthesia with the handheld instrument, the doctor needs to cooperate with the lying patient to tilt the instrument so that the catheter can penetrate into the patient's laryngeal cavity. During the tilting of the instrument, the liquid level of the anesthetic liquid in the anesthetic storage bottle tilts, resulting in the bottom of the catheter in the anesthetic storage bottle not being able to always be located in the anesthetic liquid, so that the catheter will directly draw air from the anesthetic storage bottle and spray the air into the patient's laryngeal cavity, which not only reduces the overall anesthesia efficiency, but also easily causes certain damage to the patient's laryngeal cavity, making the condition of the patient's affected area worse. To avoid this situation, in this embodiment, a rotating connecting component 3 is provided in the liquid storage bottle 1, and is used to transport the anesthetic liquid in the liquid storage bottle 1. When the doctor holds the device and pressurizes the liquid storage bottle 1 through the air blowing component 4, the anesthetic liquid is squeezed into the rotating connecting component 3 by the air pressure, so that the anesthetic liquid moves along the rotating connecting component 3. The connecting sleeve 34 is connected to the limiting ring plate 33 in a rotatable manner so that the plastic tube 35 and the connecting sleeve 34 can rotate along the circumferential direction of the receiving tube 32. When the liquid storage bottle 1 is tilted, the connecting sleeve 34 fixedly connected with the plastic tube 35 is affected by the gravity of the plastic tube 35 and rotates along the circumferential direction of the receiving tube 32, so that the bottom of the plastic tube 35 is always located at the bottom of the liquid storage bottle 1, and the anesthetic liquid in the liquid storage bottle 1 is also in the storage bottle. When the liquid bottle 1 is tilted, it gathers at the bottom of the liquid storage bottle 1, and then the bottom of the plastic tube 35 can always be located in the anesthetic liquid, and finally enters the spray component 5 through the connector 2 until it is sprayed out from the output end of the spray component 5. When the liquid storage bottle 1 is tilted, the bottom of the rotating connecting component 3 can always be deeply immersed in the anesthetic liquid in the liquid storage bottle 1, avoiding direct spraying of air during the anesthesia process, causing secondary damage to the patient's affected area, and effectively improving the spraying efficiency of the spray component 5, thereby improving the efficiency of doctors when performing anesthesia steps.

[0028] In a further embodiment of a local anesthesia sprayer, the liquid storage bottle 1 is made of a transparent material, with reference to common transparent glass bottles and transparent plastic bottles.

[0029] As a further explanation of this embodiment, the liquid storage bottle 1 in this embodiment is made of glass, so that the user can directly see the amount of anesthetic liquid in the liquid storage bottle 1, which is convenient for replenishing the anesthetic liquid.

[0030] In a further embodiment of the local anesthesia sprayer, a drainage hole 322 is formed at the bottom of the receiving tube 32 , and a sealing plug 323 is fixedly installed in the drainage hole 322 .

[0031] As a further explanation of this embodiment, some anesthetic liquid will remain at the bottom of the receiving tube 32 in this embodiment. In order to prevent the residual anesthetic liquid from affecting the subsequent use of the device, a drainage hole 322 and a sealing plug 323 are opened at the bottom of the receiving tube 32 to facilitate the discharge of residual anesthetic liquid when cleaning the device.

[0032] In a further embodiment of a local anesthesia sprayer, a plurality of balls 36 for reducing friction are slidably mounted between the two ends of the interior of the connecting sleeve 34 and the two limiting ring plates 33 .

[0033] As a further explanation of this embodiment, in this embodiment, a ball 36 is added between the limiting ring plate 33 and the connecting sleeve 34, so that the connecting sleeve 34 has less resistance during rotation, so that the plastic tube 35 can respond more quickly to the tilt state of the liquid storage bottle 1, thereby keeping the bottom of the plastic tube 35 connected to the anesthetic liquid at the bottom of the bottle.

[0034] A further embodiment of a local anesthesia sprayer, the inflation assembly 4 includes an air pipe 41 fixedly connected to the connector 2, and an air inlet 21 is provided in the connector 2 for gas in the air pipe 41 to enter, a one-way air valve is provided in the air inlet 21, an end of the air pipe 41 away from the connector 2 is fixedly connected to an air bag 42, both ends of the air bag 42 are provided with air ports, and a hard handle 43 is fixedly connected to the outside of the air pipe 41, and the hard handle 43 is in contact with the air bag 42.

[0035] As a further explanation of this embodiment, the airbag 42 in this embodiment is a commonly used sphygmomanometer airbag, so the airbag 42 has two air ports, one of which is deformed after the airbag 42 is squeezed and fills the air supply pipe 41 with gas. After the airbag 42 is released, air is taken in from the other air port to restore the airbag 42 to its initial state. During the reciprocating squeezing, deformation and recovery process of the airbag 42, the airbag 42 will continuously transport the gas into the liquid storage bottle 1 through the air supply pipe 41. In order to ensure that the gas in the liquid storage bottle 1 does not flow back, a one-way air valve for sealing the air port is installed at the air inlet 21. Since the liquid storage bottle 1 is a sealed environment, when the air pressure in the bottle continues to increase, the air pressure will force the anesthetic pressure into the plastic tube 35 and spray it out from the spray assembly 5.

[0036] A further embodiment of a local anesthesia sprayer, the spray assembly 5 includes an infusion tube 51 fixedly connected to the connector 2, the end of the infusion tube 51 away from the connector 2 is threadedly connected to an adapter 52, and the end of the adapter 52 away from the infusion tube 51 is fixedly connected to a spray tube 53.

[0037] As a further explanation of this embodiment, as a preferred solution of this example, the model of the adapter 52 in this embodiment is not fixed. The main function of the adapter 52 is to connect the spray tube 53, and the length and hardness model of the spray tube 53 are not unique. Therefore, this device is not limited to the medical scenario of laryngeal anesthesia. When the device needs to be applied to other medical scenarios, it is only necessary to connect the corresponding adapter 52 and spray tube 53.

Any person skilled in the art may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the present invention, but they should still be regarded as technologies or embodiments that are essentially the same as the present invention.

The description of the above embodiments is only used to help understand the method and core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures.
