Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The terminology used in the embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in the disclosed embodiments and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise, and "the plural" typically includes at least two.

It should be understood that the term "and/or" as used herein is merely a relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B, may represent: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a good or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such good or apparatus. Without further limitation, an element defined by the phrase "comprising a" does not exclude the presence of another, identical element in a commodity or a device comprising the element.

In the art, after mixing solid and liquid components, tissue gels, such as medical hydrogels, need to be mixed in liquid level to achieve complete and uniform gelling. The use of such a well-mixed reaction regime results in a faster reaction rate and requires timely application of the hydrogel to the tissue to be treated, thus placing high demands on the applicator. Therefore, the use of tissue glues for procedures such as wound dressing requires immediate production and use. The tissue glue, such as medical hydrogel, in the present disclosure may be formed by mixing two solutions, i.e., a first solution and a second solution, which are not very stable and cannot be stored for a long time. The first solution may be formed by reacting a first solute with a first liquid and the second solution may be formed by reacting a second solute with a second liquid. The first solute, the first liquid, the second solute and the second liquid are all substances which are easy to preserve. In order to perform medical treatment with the tissue glue of the present disclosure, it is necessary to generate a first solution using a first solute and a first liquid, generate a second solution using a second solute and a second liquid, and react the first solution and the second solution to generate the tissue glue. For this reason, there are relatively high requirements on the structure of the tissue glue application device, so that it can store at least one of the first solute, the first liquid, the second solute, and the second liquid for a long period of time, and can simply and rapidly generate and apply tissue glue when performing an operation.

The present disclosure provides a tissue glue application device comprising: a first syringe configured to contain a first liquid; a second syringe configured to contain a second liquid; and a mixing device comprising a first branch and a second branch communicated with the first injector and the second injector respectively, each of the first branch and the second branch being provided with a channel switching assembly comprising: a housing member having a housing portion; a cock rotatably disposed in the housing, the inside of the rotation being provided with a first passage and a second passage which do not interfere with each other, the cock being switchable between a first position and a second position with respect to the housing, the branch corresponding syringe communicating with the first passage in response to switching of the cock to the first position, and the branch corresponding syringe communicating with the second passage in response to switching of the cock to the second position.

The tissue glue applying device is adopted, the double syringes are used for containing two pipes of specific liquid, and correspondingly, a plurality of penicillin bottles and other containers are used for storing various solutes, so that the tissue glue applying device is beneficial to storing tissue glue forming materials. The channel switching components of the tissue glue applying device are in different states, specific liquid and specific solute are mixed to form specific solution of the two, and the two solutions are mixed to form tissue glue and are directly applied. The tissue glue is formed and utilized immediately, so that the reactants are fully mixed, the gelling reaction is uniform and rapid, and the wound surface is effectively protected.

The tap 342 includes a tap body 3423 and a piercing portion 3424. The tap body 3423 is accommodated in the accommodation portion 3411, and is rotatable in the accommodation portion 3411 with respect to the receiving member 341. The acupuncturing portion 3424 extends from an end portion of the tap body 3423 away from the tap body 3423 in the direction of the tap body axis. At least a portion of the spike 3424 is located outside of the receiving portion 3411 and is configured to pierce a container containing a powder, such as a vial containing a solute for forming a tissue glue.

The first passageway 3421 extends from the rotating body 3423 to the needle punching portion 3424, and includes a first opening 34211 on the side wall of the needle punching portion 3424, and the first opening 34211 is located outside the accommodating portion 3411.

At this time, the second opening 34212 of the first passage 3421 is abutted with the first through hole 34111, for example, sealing. In this case, if the needle puncturing portion 3424 of the cock 342 pierces the vial containing the solute (e.g., the first solute) for forming the tissue glue, the syringe (e.g., the first syringe 10) may be communicated with the vial through the first passage 3421, so that the liquid (e.g., the first liquid) of the syringe (e.g., the first syringe 10) may be driven into the vial to be mixed with the solute (e.g., the first solute) in the vial to form a first solution, and the first solution may be drawn into the syringe (e.g., the first syringe 10) by pulling the plunger of the syringe (e.g., the first syringe 10).

Similarly, the second syringe 20 may also pump the second liquid stored therein into a penicillin bottle filled with a second solute for forming tissue glue in the same manner, and after the second solution is formed, the second solution is pumped into the second syringe 20.

When the cock 342 is switched to the second position, the syringe (e.g., the first syringe 10) corresponding to the branch (e.g., the first branch 31) is in communication with the second passageway 3422. At this time, the third opening 34221 of the second passageway 3422 is abutted, e.g., sealed to the first through hole 34111, and the fourth opening 34222 of the second passageway 3422 is abutted, e.g., sealed to the second through hole 34112. That is, the branch (for example, the first branch) forms a passage, and the injector (for example, the first injector 10) corresponding to the branch (for example, the first branch 31) is communicated with the mixing pipe member 33 through the branch (for example, the first branch 31).

Similarly, the second injector 20 can inject the second solution into the mixing tube 33 in the same manner. The first solution and the second solution are mixed and reacted in the mixing tube 33 to form tissue glue.
