Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical wound treatment devices, and in particular to a medical adhesive coating device. Background Art
[0002] For many years, the use of sutures, rivets and other materials or instruments to suture wounds has been the most commonly used and effective wound bonding method in clinical practice due to its advantages of firm sutures and difficulty in wound splitting. However, with the rapid development of modern medicine, the requirements for surgical methods and auxiliary materials in clinical practice are becoming increasingly higher, not only requiring to minimize the pain of patients and shorten the wound healing time, but also requiring that the appearance be perfectly restored while recovering, so medical adhesives have begun to be widely used; In the prior art, medical adhesives packaged in glass ampoules are mostly applied by manually breaking off the bottleneck of the ampoule, and using a disposable straw to absorb the liquid. The amount of application is difficult to control during actual use, and excessive application poses certain hidden dangers. In addition, the breaking and destruction of the ampoule has certain safety hazards and may cause damage during use. The current destruction methods of ampoule tubes are mainly carried out through supporting packaging, breaking and side extrusion. Breaking requires that the material can be bent well, but the bending damage is likely to occur in the middle of the glass tube, which will cause the glass tube to be incompletely broken, and some liquid will still accumulate in the glass tube, resulting in a low utilization rate. For side extrusion damage, similar medical adhesive packaging currently uses thin-walled glass tubes with convex points set inside. The glass tube is pressed, and the glass tube is in contact with the convex points, resulting in damage. However, the force point only relies on the force of squeezing with fingers, and the thickness of the ampoule tube exceeds 0.25mm and cannot be easily destroyed. There are still certain defects in use. For example, the medical adhesive products produced and sold by Nanjing Zhuhai Biotechnology Co., Ltd. directly break the ampoule bottle during use, and use a disposable dropper to absorb the internal glue liquid and apply it to the wound surface. Because the diameter of the straw is a retractable capillary, when the liquid level is below the height of the internal capillary, the liquid cannot flow out through the diameter. This method is complicated to operate and takes a long time, and the capillary is too thin, so it may break accidentally. Another medical adhesive produced and sold by Jiangxi Bornruier Biological Co., Ltd., whose applicator invention patent application number is CN 110721397A, destroys the ampoule by squeezing the ampoule tube to make it contact with the convex points. This method has specific requirements on the thickness of the ampoule tube so that it can easily squeeze and destroy the ampoule tube; in addition, it is inconvenient to use force when squeezing, and it is more laborious to squeeze out the liquid, resulting in poor control of the application amount, which poses a hidden danger to use. For this reason, our company proposes a medical adhesive application device. Summary of the invention

After the internal ampoule tube 2 is broken by external force, the liquid is collected in the liquid storage sleeve 4, and then filtered by the filter element 6 and transported to the coating head 7 through the tip catheter of the delivery head 5, so as to achieve the transfer from the storage part to the coating part, thereby achieving the purpose of use, wherein one end of the delivery head 5 stores the filter element 6, and the other end is a tip infusion The catheter controls the liquid to not drip automatically without external force. Reinforcement ribs are arranged around the tip to prevent the tip from breaking due to uneven force when the smear head is installed. One end of the liquid storage sleeve 4 is fixedly connected to a delivery head 5. The outer diameter of the delivery head 5 is adapted to the inner diameter of the liquid storage sleeve 4 and is fixed to the unsealed end of the liquid storage sleeve 4. A filter element 6 is attached to the inside of the delivery head 5 to filter broken glass residues. The other tip catheter of the delivery head 5 is inserted into the hollow part inside the smear head. The inner side of the delivery head 5 is embedded with a filter element 6 and fixedly installed. The other end of the delivery head 5 is fixedly connected to a smear head 7. An expansion opening 101 is provided on the surface of the extruder shell 1 near one end, a slot 102 is provided on the surface of the extruder shell 1 at one side of the expansion opening 101, and a protrusion 103 is fixedly installed on the inner surface of the extruder shell 1; the pressing structure 3 includes a connecting rod 301, a clamp 302, a pressing handle 303 and an extrusion protrusion 304, the connecting rod 301 can be deformed and press downward to the internal ampoule tube 2, and the ampoule tube 2 is damaged by the force; one end of the connecting rod 301 is connected to the clamp 302, and the other end of the connecting rod 301 is connected to the pressing handle 303, and the lower surface of the pressing handle 303 is fixedly installed with an extrusion protrusion 304; the delivery head 5 is connected to the application head 7, and the liquid storage sleeve 4 and the delivery head 5 are connected through the filter element 6; the pressing structure 3 is inserted into the slot 102 through the block on the clamp 302 fixed; the length of the extruder shell 1 is 70mm, the inner diameter of the cylindrical part of the extruder shell 1 is 7.8mm, the outer diameter of the cylindrical part of the extruder shell 1 is 8.8mm, and there are three raised blocks 103 with a spacing of 0.4cm. The height range of each raised block 103 is between 1mm and 3mm; the smear head 7 is made of silicone material, and the inclination angle of the smear head 7 is preferably 45°, which is more in line with the usage habits of most operators. The silicone head has a smooth smearing slope and a hardness of 40-50A. The body surface feels relatively soft, and the plane improves the efficiency of glue application. The material of the extruder shell 1 is acrylonitrile-butadiene-styrene copolymer, and the extrusion protrusion 304 does not contact the surface of the liquid storage sleeve 4. The contact part between the extrusion protrusion 304 and the liquid storage sleeve 4 is linear, and there is a 0-8mm arc groove in the middle.
[0017] What needs instructions is a medical adhesive application device, combined with Figure 2 and Figure 3In this embodiment, the outer diameter of one end of the delivery head 5 with the filter element 6 inside is consistent with the inner diameter of the liquid storage sleeve 4, so as to make a connection; the tip catheter of the other end of the delivery head 5 can be directly inserted into the hollow part inside the smear head 7. Thus, the assembly connection of the three parts of the smear head 7, the delivery head 5 and the liquid storage sleeve 4 is achieved, so as to realize the delivery of the glue from the storage part to the smear part. The ampoule tube 2 is arranged in the internal storage part of the liquid storage sleeve 4, and the liquid storage sleeve 4 is fixed in the extruder shell 1 through interaction. The pressing structure 3 is buckled on the outside of the extruder shell 1. The whole set of devices thus completes the assembly connection; the extruder shell 1 of this embodiment has a length of 70mm, an inner diameter of the cylindrical part of 7.8mm, and an outer diameter of 8.8mm.

During the pressing process, since the bottom of the ampoule tube 2 contacts the closed end of the liquid storage sleeve 4 as a positioning point, the body of the ampoule tube 2 contacts the raised block 103, and the overall force-bearing part is in the middle and lower part of the ampoule tube 2. At this time, only a small force is needed to press the pressing handle 303 of the pressing structure 3 to break the ampoule tube, thereby achieving the purpose of rapid glue discharge, and only a small amount of glue remains on the inner wall of the ampoule tube, thereby improving the utilization rate of the glue.
