Description

Technical Field

[0001] The utility model belongs to the technical field of medical infusion sets, and in particular relates to a splash-proof glue coating mechanism of an automatic drip-stopping bucket for welding films. Background Art

[0002] The drip bucket welding film automatic liquid stop infusion set currently used in clinical practice consists of a drip bucket seat, a liquid medicine filter membrane, an extruded drip bucket, and a drip bucket cover. During assembly and production, the liquid medicine filter membrane is welded to the drip bucket seat, and the two ends of the drip bucket are respectively coated with glue and then assembled with the drip bucket seat and the drip bucket cover. However, the actual production and clinical use of the welded film liquid stop drip bucket infusion set has the following two disadvantages:

[0003] 1. When the drip bucket port is applying glue, a layer of glue film will be formed at the drip bucket port. When the glue film is broken, glue spots will splash onto the surface of the liquid filter membrane in the drip bucket seat. After the liquid filter membrane is contaminated by glue, the integrity of the liquid filter membrane performance will be affected, and the liquid filter membrane will lose its automatic liquid stopping function or precision filtration function; 2. As the glue coating head moves up and down when applying glue, glue spots will splash onto the inner wall of the drip bucket, increasing the product defective rate and the production cost of the company's products.

[0004] According to clinical studies, failure of the automatic stop function will result in air infusion into the human body, and failure of the precision filtration function will result in large particles in the drug solution entering the human body, both of which will cause adverse reactions to varying degrees, and in severe cases, vascular embolism or even death. Although in actual clinical use, patients are checked by medical staff during infusion, and it is rare for air to be infused into the patient's body or for the filtration performance to fail, this safety hazard still exists, and the risk of failure of the automatic stop performance or precision filtration performance of the drug solution filter membrane should be reduced as much as possible.

[0005] For example, the Chinese utility model patent with application number 202320226781.0 discloses a gluing mechanism for controlling the amount of glue applied, which needs to be controlled by multiple motors, so it uses more components and has a more complex structure. In addition, although it can control the amount of glue applied, it is easy to splash glue. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a glue-splashing-proof glue-coating mechanism.

[0007] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0008] A glue-splash-proof glue coating mechanism comprises a glue coating head and a glue-blocking cap for shielding glue droplets from splashing, the glue coating head is provided with a glue storage groove and a glue discharge hole for discharging residual glue in the glue coating head, the center of the glue coating head is provided with an internal thread, the bottom of the glue-blocking cap is provided with an external thread threadedly connected to the internal thread, and the height of the glue-blocking cap and the glue coating head is adjustable through the internal thread and the external thread.

[0009] Preferably, the rubber blocking cap is provided with two layers of shielding.

[0010] Preferably, the rubber stop cap comprises a first core rod, a first rubber stop cap disposed on the upper end of the first core rod, a second core rod disposed on the upper end of the first rubber stop cap, and a second rubber stop cap disposed on the upper end of the second core rod.

[0011] Preferably, the diameter of the second section of the core rod is smaller than the diameter of the first section of the core rod.

[0012] Preferably, the external thread is arranged at the bottom of the first section of the core rod.

[0013] Preferably, the glue discharge hole is arranged on the outer ring of the internal thread, and the glue storage groove is arranged on the outer ring of the glue discharge hole.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The height of the glue stopper cap and the glue coating head is adjustable through the internal and external threads. Therefore, the glue stopper cap and the glue coating head are assembled by screwing the threads. At the same time, the height of the glue stopper cap is adjustable through the threaded hole. Therefore, the height of the glue coating on the inner wall of the drip bucket can be controlled by contacting with the inner wall of the drip bucket.

[0016] 2. By setting a glue storage groove at the bottom of the glue coating head, the amount of glue dipped at the dripping bucket can be effectively controlled by the depth of the glue storage groove;

[0017] 3. The utility model is lifted up to contact the drip bucket and apply glue. During the falling process, the glue film at the drip bucket port is torn during multiple diameter changes due to the obvious outer diameter difference between the glue coating head, the first section core rod, the first layer of glue blocking cap, and the second section core rod. Due to the shielding effect of the second layer of glue blocking cap on the top, the glue droplets are effectively prevented from splashing onto the inner wall of the drip bucket and the liquid medicine filter membrane at the other end of the drip bucket, ensuring that the liquid medicine filter membrane is not contaminated and corroded by the glue, and the safety performance of clinical use is greatly improved;

[0018] 4. Since the glue caps before and after the glue coating are located just below the mouth of the drip bucket to provide shielding, the glue drops generated during the glue pool action of the utility model are effectively prevented from splashing onto the inner wall of the drip bucket, thereby improving the qualified rate of the drip bucket glue coating production;

[0019] In summary, the utility model solves the problems of glue splashing caused by rupture of the glue film at the drip bucket port and glue splashing caused by the action of the glue coating head, thereby improving product safety and reliability, improving production qualification rate, and its structure is simple.

[0027] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0028] Embodiment 1:

[0029] like Figure 1-6 As shown, a glue splash-proof glue coating mechanism includes a glue coating head 9 and a glue blocking cap 12 for shielding glue droplets from splashing. The glue coating head 9 is provided with a glue storage groove 8 and a glue discharge hole 7 for discharging residual glue in the glue coating head 9. The center of the glue coating head 9 is provided with an internal thread 6. The bottom of the glue blocking cap 12 is provided with an external thread 1 threadedly connected to the internal thread 6. The height of the glue blocking cap 12 and the glue coating head 9 is adjustable through the internal thread 6 and the external thread 1. Therefore, the glue blocking cap 12 is assembled with the glue coating head 9 by screwing, and the height of the glue blocking cap 12 is adjustable through the threaded hole. Since there is a glue storage groove 8 at the bottom of the glue coating head 9, the amount of glue dipped at the drip bucket mouth can be effectively controlled.

[0030] Furthermore, the glue coating head 9 has a certain height, and can control the glue coating height of the inner wall of the dripping bucket 10 by contacting with the inner wall of the dripping bucket 10 .

[0031] Embodiment 2:

[0032] A splash-proof glue coating mechanism is different from the embodiment 1 in that the glue blocking cap 12 is provided with two layers of shielding.

[0033] like Figure 4 As shown, the rubber blocking cap 12 includes a first-section core rod 2, a first-layer rubber blocking cap 3 arranged at the upper end of the first-section core rod 2, a second-section core rod 4 arranged at the upper end of the first-layer rubber blocking cap 3, and a second-layer rubber blocking cap 5 arranged at the upper end of the second-section core rod 4. Furthermore, the outer diameters of the first-section core rod 2 and the second-section core rod 4 have obvious outer diameter differences from the outer diameters of the first-layer rubber blocking cap 3 and the second-layer rubber blocking cap 5.

[0034] In this embodiment, the diameter of the second section core rod 4 is smaller than the diameter of the first section core rod 2 , and the external thread 1 is arranged at the bottom of the first section core rod 2 .

[0035] Furthermore, Figure 6 As shown, the glue discharge hole 7 is arranged on the outer circle of the internal thread 6 , and the glue storage groove 8 is arranged on the outer circle of the glue discharge hole 7 .

[0036] The gluing process of the utility model is:

[0037] Before gluing, the glue head of the gluing head 9 is immersed below the glue liquid level, and the glue blocking cap 12 is above the glue liquid level. When gluing, the cylinder clamp drives the gluing mechanism to move upward, and the glue blocking cap 12 and the gluing head 9 are successively inserted into the drip bucket 10 until the end of the drip bucket 10 contacts the glue storage tank 8 for gluing. After the gluing is completed, the gluing mechanism falls back to its original position, and the glue storage tank 8, the gluing head 9, the first section core rod 2, the first layer of glue blocking cap 3, the second section core rod 4, and the second layer of glue blocking cap 5 are successively separated from the end of the drip bucket 10, and one gluing is completed.

[0038] There are two ways of splashing glue: Glue splashing process 1: After the end of the drip bucket 10 is dipped in glue in the glue storage tank 8, a glue film is easily formed at the end of the drip bucket 10. After the glue film breaks, the glue spots will splash onto the liquid filter membrane 11 in the drip bucket 10 and the inner wall of the drip bucket 10.

[0039] Glue splashing process 2: When the glue coating mechanism repeatedly dips and coats the glue in the glue pool, glue will splash into the drip bucket 10, contaminating the inner wall of the drip bucket 10 and the liquid filter membrane 11 at the other end of the drip bucket 10.

[0040] Therefore, the utility model solves the problems of glue splashing caused by the rupture of the glue film at the port of the drip bucket 10 and the glue splashing caused by the action of the glue coating head 9, improves product safety and reliability, improves the production qualification rate, and has a simple structure.
