Description

Technical Field

[0001] This utility model relates to the field of anesthesia video laryngoscope viewing film technology, specifically a universal locking and positioning structure for anesthesia video laryngoscope viewing film. Background Technology

[0002] In the use of anesthesia video laryngoscopes, the accompanying viewing slide needs to be soaked and disinfected after each use. Therefore, the viewing slide and the main unit of the anesthesia video laryngoscope are separate structures. The viewing slide and the main unit of the anesthesia video laryngoscope rely on elastic positioning beads for limiting their position. In actual operation, the viewing slide and the main unit of the anesthesia video laryngoscope are prone to detachment, and it is necessary to relock them and restart the machine. This phenomenon directly affects the efficiency of endotracheal intubation.

[0003] Furthermore, because the size of the endoscopic lens varies depending on the patient, the force with which the lens detaches also differs, further exacerbating these problems.

[0004] To address this, a universal locking and positioning structure for anesthesia video laryngoscope viewing films is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a universal locking and locking structure for the viewing film of anesthesia video laryngoscope, which solves the problem of the viewing film easily detaching during use. It allows for operation in different directions according to the actual situation without worrying about the viewing film detaching. It can be adapted to viewing films of different sizes and has strong versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A universal locking and positioning structure for anesthesia video laryngoscope viewing film includes a lens hook, with a left handle and a right handle respectively installed on both sides of the lens hook;

[0008] The left and right handles are provided with mutually cooperating elastic components;

[0009] The lens hook is equipped with a positioning structure for use with an external viewing lens.

[0010] Furthermore, a spring-loaded positioning bead is installed on one side of the left handle.

[0011] Furthermore, a spring positioning pin is installed on one side of the right handle.

[0012] Furthermore, the elastic positioning bead and the spring positioning pin constitute an elastic component.

[0013] Furthermore, the positioning structure is a positioning pin.

[0014] Furthermore, the positioning pin engages with the lens hook groove on the viewing lens.

[0015] Furthermore, a metal lens is provided at the bottom of the lens hook.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In terms of operation, there are only four steps required for both use and post-use: docking, locking, unlocking, and disconnecting;

[0018] 2. Wide application: There is no need to consider the universality of viewing lenses of different specifications and sizes. This structure can be used with viewing lenses of various sizes, and the same fixing effect can be achieved after locking.

[0019] 3. Good stability: Because of the use of spring pins, there is no need to worry about the viewing plate detaching due to large movements or other factors during operation. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1:

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] The universal locking and positioning structure for anesthesia video laryngoscope viewing films includes a lens hook 1, a left handle 2 and a right handle 3 installed on both sides of the lens hook 1, and an elastic component that cooperates with each other between the left handle 2 and the right handle 3. The lens hook 1 is provided with a positioning structure that is used in conjunction with an external viewing film.

[0029] like Figure 1 As shown:

[0030] The left handle 2 has a spring positioning bead 5 installed on one side, and the right handle 3 has a spring positioning pin 6 installed on one side. The spring positioning bead 5 and the spring positioning pin 6 form an elastic component.

[0031] like Figure 1 As shown:

[0032] The positioning structure is a positioning pin 7. The positioning pin 7 is connected to the lens hook groove on the viewing film to complete the assembly. The bottom of the lens hook 1 is provided with a metal lens 8.

[0033] Operating principle:

[0034] Select the viewing lens of the corresponding size and specifications before use.

[0035] The lens hook slot on the viewing film is aligned with the positioning pin 4 to provide a positioning function for subsequent locking. Figure 2 ).

[0036] Rotate the viewing plate; at this point, the viewing plate comes into contact with the elastic positioning bead 5 and the spring positioning pin 6. Figure 3 ).

[0037] Continue rotating the viewing lens. The spring positioning bead 5 and spring positioning pin 6 are under pressure, causing the spring to contract. The viewing lens reaches the predetermined locking position. At this point, the spring positioning bead 5 and spring positioning pin 6 are in a free-flowing state and return to their original positions under the spring force. The viewing lens is now locked in place, preventing it from coming loose under pressure. Figure 4 , Figure 5 ).

[0038] After use, to unlock and detach the viewing plate, simply push out the spring positioning pin 6 lever. The spring positioning pin 6 will be pulled, and the pin head will retract back into the spring pin. Rotating the viewing plate will then unlock and detach it.

[0039] Similarly, it can be applied to various models and sizes of viewing lenses.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
