Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drug delivery assisting devices, in particular to a positioning device for aerosol drug delivery. BACKGROUND

[0002] At present, inhalation anesthetics are very important for local anesthesia of the larynx and trachea during laryngoscopy and tracheoscopy, which can significantly reduce the patient's coughing and pain, and improve the patient's cooperation and comfort. For patients undergoing tracheal intubation under general anesthesia, especially for elderly patients, good local anesthesia intubation can not only reduce the amount of general anesthetics, but also significantly reduce cardiovascular stress response and avoid cardiovascular accidents. Most of the existing local anesthetics are administered by spray pot. However, when the spray pot is used for drug delivery, the drug cannot be accurately delivered to the position where the patient needs to be administered. For the scenario of administering a canister drug such as lidocaine aerosol, a drug delivery straw is generally installed at the spray opening of the aerosol canister to drain the aerosol through the straw and spray it near the target position. However, the existing drug delivery straw is short and cannot be bent according to the target administration position. It is difficult to find an appropriate spray angle for accurate drug delivery in actual use. The poor positioning accuracy of the existing drug delivery makes the drug delivery inefficient, which is not conducive to local anesthesia of the larynx and trachea. CONTENT OF THE UTILITY MODEL

[0023] The preferred embodiments of the present application are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and do not limit the present application.

[0024] In the present application, the meaning of "and / or" means that each single existence or both existences are included.

[0025] The "inner, outer" in the present application refers to the direction pointing to the inner center of the support frame, and the opposite direction is outer, which is not a specific limitation of the device mechanism of the present application.

[0026] The "connection" in the present application can be a direct connection between components or an indirect connection between components through other components.

[0027] The "upper, lower" in the present application refers to the direction pointing to the outlet of the medicine bottle when the user faces the positioning device installed outside the medicine bottle, and the opposite direction is lower, which is not a specific limitation of the device mechanism of the present application.

[0028] The positioning device for aerosol administration provided by the present application has the advantages of Figure 1 as shown in the

[0029] The support frame 3 is detachably fixed outside the medicine bottle, for example, it can be provided as a steel wire fixed around the medicine bottle, or a ring-shaped bottle sleeve clamped on the outer wall of the medicine bottle;

[0030] The hose 1 is detachably connected to the support frame 3 and has a flexible bending degree to accurately guide the medicine output from the medicine bottle to the target position. For example, the hose 1 can be fixed on the extension of the steel wire by winding to provide guidance by the steel wire structure, or one end of the hose 1 can be detachably and sealingly connected to the medicine outlet of the medicine bottle through the fixing structure on the ring-shaped bottle sleeve, and the other end of the hose 1 is extended to the target administration position.

[0031] Therefore, the present application can use the support frame with bending degree to detachably and sealingly connect one end of the hose to the medicine outlet of the medicine bottle, and accurately extend the other end of the hose to the target administration position by bending the support frame structure, solving the problems of poor accuracy and low efficiency of existing positioning administration.

[0032] To facilitate the fixation of the hose, the present application can further provide Figure 3 a flexible support structure 2 between the support frame 3 and the hose 1, which is bent and wound with the hose 1 to fix the bending radius of the hose 1.

[0033] The flexible support structure 2 used in the present application can generally be realized by metal wires and / or metal strips. It has a certain plasticity, and the extension direction and bending angle at different positions can be changed by manual bending to guide the hose fixed thereon to the target spraying position in the appropriate direction.

[0034] To protect the hose, the application further generally has a flexible covering structure fixed outside the metal wire and / or metal strip. The flexible covering structure can avoid the metal structure being directly exposed and puncturing the air pipe. The flexible covering structure can be realized by any one of fabric, flexible polymer material, silica gel strip, rubber strip, adhesive tape, and can also be realized by flexible combination thereof. The flexible covering structure is synchronously wound outside the hose 1 with the metal wire and / or metal strip, which on one hand limits the deformation displacement between the hose and the metal support structure through the covering structure, and on the other hand also protects the hose in use to avoid damage caused by external force.

[0035] For the fabric or adhesive tape, it can be connected on the metal wire, metal strip or the like structure by the way of bandage or the way of winding and wrapping, and the hose is guided and shaped by the way of binding or the adhesion of the adhesive tape. For the flexible support structure adopting plastic, plastic or other flexible polymer material or adopting silica gel strip, rubber strip or other covering structure, the application can adopt the way shown in the figure to set a groove 5 on the surface thereof, so as to clamp the hose 1 in the groove, and the hose is fixedly connected with the metal wire and / or metal strip through the groove to realize the guidance. In the groove, the metal wire and / or metal strip of the flexible support structure 2 can be arranged at the position of the two side walls of the groove or can be directly arranged at the bottom of the groove. Figure 2

[0036] To facilitate the connection of the flexible support structure 2, the application can further set a connecting arm 4 extending from the support frame body to the connection position of the hose 1 as shown in the figure; the connecting arm 4 can be arranged as a rigid structure of the same material as the support frame, or can be arranged as an independent part by using flexible material or material capable of plasticity and having supporting effect, so as to adjust the connection angle of the flexible support structure 2 through the bending degree of freedom of the connecting arm 4 itself to facilitate the positioning of the hose. The flexible support structure 2 is generally arranged to be fixedly connected with the extension end of the connecting arm 4, for example, the two are arranged as a whole. However, it can be understood by those skilled in the art that the flexible support structure 2 is fixedly installed on the extension end of the connecting arm by any other way such as buckle, clamping piece, joint connecting structure, which generally does not bring negative influence on the effect, and therefore should also be included in the protection scope of the application. Figure 2 In some more flexible implementation ways, the support frame 3 of the application can be arranged as a half-round clamping structure to be clamped and fixed with the outer wall of the medicine bottle, or the support frame 3 can also be arranged as a snap or bandage having a flexible structure connection to be fixed on the medicine bottle in the way of embracing, or the support frame 3 can also be directly arranged as a bottom support for accommodating the medicine bottle to realize the fixed connection in the way of directly supporting the medicine bottle.

[0037]

[0038] ​​The soft tube 1 used in the present application can be made of silica gel material or medical rubber or medical flexible plastic material. The inner diameter of at least one end of the soft tube matches the outer diameter of the medicine outlet of the medicine bottle, for example, it can be slightly smaller than the outer diameter of the medicine outlet of the medicine bottle to improve the sealing performance during the spraying process of the medicine outlet, or it can be directly set to the same size as the outer diameter of the medicine outlet. The other end of the soft tube 1 can be set according to the type of the medicine bottle, and in the use scenario of directly outputting liquid medicine from the medicine outlet, a spray head is provided to atomize the medicine through a plurality of small holes provided on the spray head, so that the liquid output medicine can act on the target position in the form of fine droplets. Or, when used for lidocaine aerosol and other canned medicines, the free end of the soft tube can also be directly set as bare to directly act on the target position.

[0039] The advantage of the present application is that the flexible support structure provides flexible support for the soft tube, which can be flexibly maintained in a proper curved state according to the spraying position, effectively avoiding interference and obstacles through the bending of the soft tube, and accurately extending into the laryngeal and tracheal parts for point and directional medicine spraying. The present application can effectively guide the medicine to the target spraying position, improve the accuracy of drug positioning, improve the efficiency of drug administration, and is beneficial to the local anesthesia of the larynx and trachea.
