Description

Technical Field

[0001] This utility model belongs to the technical field of medical devices and daily necessities, and specifically relates to an instant applicator with pre-filled application liquid. Background Technology

[0002] Currently, the main method for disinfecting, applying medication, or applying oil (all disinfectants, medications, and oils are referred to as smears) to wounds or skin involves pouring the smear onto a sterile cotton ball, then using tweezers to apply it to the wound or skin. This method is prone to the following problems during the disinfection and application process:

[0003] 1) The cotton ball containing the medicated solution held by tweezers is easy to fall off during application, affecting the operation; 2) Uneven force applied at the contact point between the cotton ball and the skin leads to uneven application; 3) The amount of medicated solution is difficult to control or is wasted; 4) Sterile cotton fibers are easy to stick to the wound, which is not conducive to wound healing; 5) The operation is cumbersome and easy to cause contamination. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide an instant applicator with pre-filled application liquid, which improves the uniformity of application, reduces waste of application liquid, and is for single use only, thus avoiding cross-contamination.

[0005] This utility model provides the following technical solution: an instant applicator with pre-filled application liquid, comprising an applicator body and a liquid reservoir. The applicator body includes a hollow applicator handle and an application head disposed at the front end of the applicator handle. The liquid reservoir contains application liquid and is inserted into the applicator handle. A sealing film is disposed at the front end of the reservoir. The interior of the applicator handle is provided with an opening structure for cutting the sealing film.

[0006] Furthermore, the application head includes a support, on which a sponge is disposed.

[0007] Furthermore, the reservoir rod and the applicator handle are connected by a threaded structure.

[0008] Furthermore, the film-opening structure is at least one protrusion disposed on the inner sidewall of the applicator handle.

[0009] Furthermore, the end of the liquid storage rod has no opening structure, but an extrusion device is provided at the opening.

[0010] By adopting the above-mentioned technology, the beneficial effects of this utility model compared with the prior art are as follows:

[0011] 1) Based on the structural design of the applicator body and the liquid storage rod, this utility model uses a threaded insertion connection method to control the amount of liquid flowing out, avoiding the waste caused by too much liquid and the problem of not being able to apply too little liquid.

[0012] 2) In this utility model, based on the setting of the film opening structure, the sealing film can be cut open by twisting, and the coating liquid flows from the liquid storage rod to the coating head, without the coating cotton ball falling off.

[0013] 3) This utility model adopts a single-use method, which avoids the occurrence of cross-infection;

[0014] 4) In this utility model, the liquid storage rod can be rotated to apply the liquid, which is simple in structure and easy to operate. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0021] An instant applicator with pre-filled application solution, such as Figure 1 As shown, it includes the applicator body and the liquid reservoir 3.

[0022] Specifically, such as Figure 2As shown, the applicator body includes an applicator handle 1 and an applicator head 2 disposed at the front end of the applicator handle 1. The applicator handle 1 and the applicator head 2 are both hollow structures and are connected to each other. The applicator head 2 includes a support 201, on which a sponge 202 is attached.

[0023] like Figure 2 and Figure 3 As shown, a base plate is provided radially inside the applicator handle 1. A set of through holes are provided on the base plate, and a film-opening structure 4 is provided axially. The film-opening structure 4 consists of multiple circumferentially arranged protrusions with spike-shaped heads. An internal thread structure is provided on the inner side wall of the applicator handle.

[0024] Specifically, such as Figure 4 As shown, the front end of the liquid reservoir 3 is provided with a sealing film, and the rear end is provided with a squeezing device 5, which can be pre-filled with application liquid. Its outer side wall is provided with an external thread that matches the internal thread structure on the applicator handle; its tail end is provided with a squeezing device 5, which is an elastic and squeezeable structure, similar to a bladder-like structure.

[0025] The reservoir rod 3 is inserted into the applicator handle 1 from one side and rotates and advances within the applicator handle 1 through a threaded engagement structure. When the sealing film contacts the opening structure 4, the rotation of the reservoir rod 3 cuts the sealing film, and the application liquid flows from the reservoir rod 3 along the applicator handle 1 to the application head 2. At the same time, the liquid can be squeezed by the squeezing device at the tail end of the reservoir rod 3 so that the liquid flows more quickly from the applicator handle 1 to the application head 2.

[0026] In this embodiment, the applicator has a pre-filled applicator liquid in the reservoir 3. The amount of applicator liquid is controlled by screwing the reservoir 3 into the internal thread of the applicator handle 1, which solves the problems of waste caused by too much applicator liquid and uneven application due to too little applicator liquid. The seal of the reservoir 3 can be cut open immediately, and the applicator liquid flows through the reservoir 3 to the applicator head 2 without falling off during use. In addition, it adopts a disposable method to avoid cross-contamination. The whole structure is simple and easy to use.

[0027] The applicator in this embodiment is not limited to medical liquid application, but can also be used for fluid application in daily life.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
