Embodiment 1

[0045] Embodiment 1: Extruder with triangular prism-shaped convex point in the middle

[0046] combine image 3 , Figure 13 In this embodiment, the outer diameter of one end of the bottle stopper 2 with the filter element 7 inside matches the inner diameter of the smear bottle 3, thereby connecting; the hollow part. In this way, the component connection of the applicator head 1, the bottle stopper 2 and the applicator bottle 3 is achieved, so as to realize the delivery of the glue from the storage part to the applicator part. The ampoule tube 8 is arranged in the internal storage part of the smear bottle 3, and the smear bottle 3 is fixed on the closed end of the bottom of the extruder 4 through a plug-in connection method. The entire device is thus completed with component connections.

[0047] combine Figure 4 , Figure 6, The extruder 4 of this embodiment has a length of 6.8cm, an inner diameter of the cylindrical part of 9.1mm, and an outer diameter of 10.8mm. The...

Embodiment 2

[0048] Example 2: Extruder with a conical convex point in the middle

[0049] combine Figure 7 , The extruder of this embodiment has a length of 6.8cm, an inner diameter of the cylindrical part of 9.1mm, and an outer diameter of 10.8mm. There are two raised points 9 and 10 inside the extruder, both of which are cones, wherein the diameter of the bottom surface of the cone is 3mm, the bottom angle is 60-80°, preferably 70°, and the raised point 10 is located The part of the card slot with a limit function set by the length is 4.6cm away from the bottom; the raised point 9 is located in the middle of the ampoule tube, 2.6cm away from the bottom, and the distance between the two raised points is 2cm. During use, the bottom of the ampoule tube is fixed on the extruder The closed end of the bottom, the middle part contacts the raised point 9, when the top of the ampoule tube is pressed, the raised point 8 acts as the fulcrum of the lever, and the closed end of the extruder acts a...

Embodiment 3

[0050] Example 3: Extruder with triangular prism-shaped convex points at the bottom

[0051] combine Figure 8 , The extruder of this embodiment has a length of 6.8cm, an inner diameter of the cylindrical part of 9.1mm, and an outer diameter of 10.8mm. There are two convex points 11 and 12 inside the extruder, both of which are triangular prisms with a height of 3mm, and the bottom is an equilateral triangle with a side length of 2-3mm. The part of the card slot with a limit function is 4.6cm away from the bottom; the raised point 11 is located at the bottom 1 / 3 of the ampoule tube, the distance between the raised point 11 and the raised point 12 is 3.1cm, and the distance between the raised point 11 and the closed end of the bottom of the extruder is 1.5cm , the closed end of the smear bottle attached with the ampoule tube is fixed on the closed end of the bottom of the extruder. Due to the support of the convex point 11 inside the extruder, the upper part of the ampoule tub...

Abstract

The invention discloses a medical adhesive applicator, and relates to a device for applying medical adhesives packaged by glass ampoule tubes. The medical adhesive applicator disclosed by the invention comprises an applying head, an ampoule plug, a filter core, an ampoule tube, an applying ampoule and an extruder. The filter core is adhered with the interior of the ampoule plug; one end of the ampoule plug is connected with the unenclosed end of the applying ampoule inside of which the ampoule tube is mounted while the other end of the ampoule plug is provided with a sharp end catheter, and the sharp end catheter is inserted into a hollow part of the inner part of the applying head; and the enclosed end of the applying ampoule is inserted into an enclosed circular tube part of the bottom of the extruder; and two protruding points are arranged on the inner wall of the extruder. According to the device disclosed by the invention, the ampoule tube arranged in the applying bottle contactswith the protruding points formed in the inner wall of the extruder through extruding the applying bottle, local pressure intensity is increased by utilizing a lever principle, so that a better crushing effect of the ampoule tube can be achieved, and higher utilization ratio of glue liquid and higher glue discharging velocity can be achieved; and moreover, a user also can crush the glass ampoule tube more easily, and thus, the convenient and quick using effect is achieved. The medical adhesive applicator disclosed by the invention has the advantages of being simple in structure and higher in practicability.

Description

technical field [0001] The invention relates to a medical adhesive application device, in particular to a medical adhesive application device packaged in a glass ampoule tube. Background technique [0002] As an emerging medical product that replaces postoperative stitches, medical adhesives provide a new method for postoperative tissue repair. The main component of widely used medical adhesives is α-cyanoacrylate, which has the characteristics of fast curing time and high closure strength. The packaging of medical adhesives used in clinical operations today is mostly filled and sealed in glass ampoules to maximize the shelf life of medical adhesive products. [0003] While the use of glass ampoules to encapsulate medical adhesive products improves the stability of product performance, there are also some problems in the use of clinical operations. For example, the medical adhesive product produced and sold by Guangzhou Baiyun Medical Adhesive Co., Ltd. under the trade nam...
