Abstract

The utility model relates to the technical field of medical equipment, in particular to a gluing device for a medical flushing sleeve. According to the scheme, through rotation of the rotating disc and design of the glue guiding holes, automatic guiding and uniform coating of glue are achieved. When the rotating disc rotates, glue in the glue storage pool can be periodically immersed into the glue guiding holes, and the glue is guided into the gluing holes.

Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a glue coating device for a medical flushing sleeve. Background Art

[0002] As a medical product, medical irrigation sets are widely used in many surgical fields, including but not limited to dentistry and minimally invasive surgery. Its structure usually includes one or more irrigation heads and a container for loading the cleaning fluid. In actual use, the irrigation head is connected to the container to effectively transport the cleaning fluid to the surgical site that needs to be cleaned or rinsed, thereby meeting the cleaning needs during delicate medical operations such as minimally invasive surgery.

[0003] In the prior art, when connecting the flushing head to the container, a beaker is often used to load cyclohexanone (a chemical with special effects). The main function of cyclohexanone is to swell the PPT tube for subsequent bonding. However, there are a series of technical defects in the traditional operation process.

[0004] First, the traditional operation method is usually to immerse the nozzle of the flushing head to be connected in a container containing cyclohexanone, so as to apply cyclohexanone to the nozzle. However, the problem with this method is that in the process of applying the liquid medicine, not only will the outside of the pipe be adhered to cyclohexanone, but the inside of the pipe will also inevitably contact the liquid medicine. This not only causes a waste of liquid medicine, but cyclohexanone is corrosive to PVC materials, which may cause unnecessary damage to the inside of the pipe.

[0005] Secondly, if cyclohexanone is also stuck inside the tube, there may be a risk of drug leakage during the blood or drug passing process. Although cyclohexanone will volatilize, in some cases, its residue may pose a threat to the quality and safety of the product.

[0006] In summary, there are many deficiencies in the use of cyclohexanone in the production process of external flushing sleeves, which not only affects the production efficiency but may also have an adverse effect on product quality. Summary of the invention

[0007] In order to solve the above problems, the utility model discloses a glue coating device for a medical flushing sleeve.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions: a glue coating device for a medical flushing sleeve, comprising a glue storage tank and a turntable rotatably arranged in the glue storage tank, wherein the turntable is provided with a glue coating hole along its axial centerline direction, and the turntable is provided with a plurality of glue introduction holes in a circumferential direction, each of the glue introduction holes is connected to the glue coating hole, and an avoidance hole is provided on the outer side of the glue storage tank corresponding to the glue coating hole, so that the end of the medical flushing sleeve can enter the glue coating hole through the avoidance hole;

[0009] When applying glue, the glue introduction hole on the rotating disk can be immersed in the glue in the glue storage tank.

[0010] In a possible implementation, the glue coating device further includes a glue storage barrel, the lower end of which is connected to the glue storage pool via a pipeline, the top end of the inner cavity of the glue storage pool is sealed and can form a negative pressure cavity.

[0011] Furthermore, the plurality of glue introduction holes are arranged in pairs, and each pair of glue introduction holes are arranged opposite to each other in the radial direction of the rotating disk.

[0012] In the above scheme, the side of the glue introduction hole outside the turntable is provided with a liquid blocking edge. When the turntable rotates, the side of the glue introduction hole without the liquid blocking edge is first immersed in the glue in the glue storage tank.

[0013] Specifically, the liquid blocking edge is in an arc shape surrounding one side of the glue introducing hole.

[0014] In the above solution, the outer side of the avoidance hole has a circle of chamfer.

[0015] In the above solution, the turntable is driven to rotate manually or automatically.

[0016] In the above solution, the turntable is driven by a motor to perform rotational motion.

[0017] In the above solution, the top of the glue storage tank is covered with a transparent cover plate.

[0018] The scheme of the embodiment of the present application utilizes the rotation of the turntable and the design of the glue introduction hole to realize the automatic introduction and uniform coating of glue. When the turntable rotates, the glue introduction hole will periodically immerse the glue in the glue storage tank and introduce the glue into the glue coating hole. As the turntable continues to rotate, the glue will be evenly coated on the end of the medical flushing sleeve under the action of centrifugal force and gravity. Since the end nozzle of the medical flushing sleeve will not be directly immersed in the glue, the glue is directly coated from the outside of the nozzle, thereby avoiding the situation where glue appears inside the nozzle. In addition, the entire glue coating process can be automated, which is conducive to improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0025] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention.

Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0027] Example 1: Figure 1-3 As shown, a glue coating device for a medical flushing sleeve comprises a glue storage pool 100 and a turntable 200 rotatably arranged in the glue storage pool 100, wherein the turntable 200 is provided with a glue coating hole 201 along its axial direction, and a plurality of glue introduction holes 202 are provided in the circumference of the turntable 200, each of the glue introduction holes 202 is connected to the glue coating hole 201, and an avoidance hole 101 is provided on the outer side of the glue storage pool 100 corresponding to the glue coating hole 201, so that the end of the medical flushing sleeve can enter the glue coating hole 201 through the avoidance hole 101; when coating glue, the glue introduction hole 202 on the turntable 200 can be immersed in the glue in the glue storage pool 100.

[0028] During operation, the end tube mouth of the medical flushing sleeve to be coated with glue is inserted into the glue coating hole 201 through the avoidance hole 101. When the turntable 200 rotates, the glue introduction hole 202 thereon will immerse the glue in the glue storage tank 100 and retain part of the glue. When the end of the medical flushing sleeve enters the glue coating hole 201 through the avoidance hole 101, as the turntable rotates, the glue will further enter the glue coating hole 201 through the glue introduction hole 202 under the action of gravity, and fall onto the end of the medical flushing sleeve placed in the glue coating hole 201. At this time, the medical flushing sleeve can be rotated again to coat the circumference with glue. Since the end tube mouth of the medical flushing sleeve will not be directly immersed in the glue, the glue is directly coated from the outside of the tube mouth, thereby avoiding the situation where glue appears inside the tube mouth.

[0029] The scheme of this embodiment utilizes the rotation of the rotating disk and the design of the glue introduction hole to realize the automatic introduction and uniform coating of glue. When the rotating disk rotates, the glue introduction hole will periodically immerse the glue in the glue storage tank and introduce the glue into the glue coating hole. As the rotating disk continues to rotate, the glue will be evenly coated on the end of the medical flushing sleeve under the action of centrifugal force and gravity. The whole glue coating process can be automated, which is conducive to the improvement of production efficiency.

[0030] In a possible implementation, the bottom of the glue storage tank 100 is designed as an inclined surface, and a glue discharge port is provided at the lowest point to facilitate replacement and cleaning of glue. At the same time, an anti-stick coating can be attached to the inner side of the wall of the glue storage tank 100 to prevent glue from sticking.

[0031] In order to prevent excessive glue from remaining in the glue coating holes 201 , the plurality of glue introduction holes 202 are arranged in pairs, and each pair of glue introduction holes 202 are arranged opposite to each other in the radial direction of the rotating disk 200 .

[0032] When the turntable 200 rotates, one glue introduction hole 202 will be immersed in the glue first, and as the turntable rotates, the hole will gradually leave the glue, and when the glue introduction hole 202 rotates to the vertical direction, the other glue introduction hole 202 corresponding to it and opposite to it will be located in the glue. On the one hand, this alternating dipping method can ensure that the glue in the glue coating hole 201 is updated and replenished in time; on the other hand, the excess glue in the glue coating hole 201 can fall into the glue storage tank 100 through the other glue introduction hole 202 corresponding to it and opposite to it, thereby avoiding excessive accumulation of glue in the glue coating hole 201.

[0033] Example 2: Figure 1-2 As shown, the glue coating device further includes a glue storage barrel 300, the lower end of which is connected to the glue storage pool 100 through a pipeline, and the top of the inner cavity of the glue storage pool 100 is sealed and can form a negative pressure cavity.

[0034] In the initial state, the upper end of the glue storage barrel 300 is evacuated to form a closed state. When the liquid level in the glue storage tank 100 is too low, for example, when the liquid level in the glue storage tank 100 is lower than the pipe mouth, some air can enter from the pipe mouth to the top of the glue storage barrel 300 to form a negative pressure chamber 301.

[0035] Since negative pressure (vacuum state) is formed at the upper end of the glue storage barrel 300, a pressure difference is formed with the atmospheric pressure. When the liquid level in the glue storage pool 100 drops below the pipe opening, air can enter the negative pressure chamber 301 at the upper end of the glue storage barrel 300 through the pipe, further reducing the pressure in the glue storage barrel 300, thereby increasing the pressure difference between the glue storage barrel 300 and the atmosphere. This pressure difference is the driving force for the glue to flow from the glue storage barrel 300 to the glue storage pool 100.

[0036] At this time, the glue (cyclohexanone) stored in the glue storage barrel 300 enters the glue storage tank 100 through the pipeline, thereby replenishing the glue storage tank 100. The solution of this embodiment uses physical principles to achieve automatic replenishment of liquid, without the need for additional electricity or pumping equipment, thereby saving energy and reducing equipment costs. When the liquid level is too low, glue can be automatically replenished, realizing automated management and reducing the need for manual intervention.

[0037] Example 3: Figure 4-5 As shown, the glue introduction hole 202 is provided with a liquid blocking edge 221 on one side outside the turntable 200. When the turntable 200 rotates, the side of the glue introduction hole 202 where the liquid blocking edge 221 is not provided is first immersed in the glue in the glue storage tank 100. Specifically, the liquid blocking edge 221 is in an arc shape surrounding one side of the glue introduction hole 202.

[0038] The liquid blocking edge 221 can intercept part of the glue, and as the turntable 200 rotates, the intercepted part of the glue enters the glue introduction hole 202 to prevent the amount of glue entering the glue introduction hole 202 from being too small.

[0039] Example 4: Figure 1-2 As shown, the outer side of the avoidance hole 101 has a circle of chamfers, which start from the edge of the avoidance hole 101 and gradually transition to the outer side and the inner side at a gentle angle. The chamfers provide a gradual guide surface for the entry of the flushing sleeve. Such a structure allows the flushing sleeve to be inserted into the avoidance hole more easily and smoothly, while also avoiding scratches or jamming caused by sharp edges.

[0040] Embodiment 5: The turntable 200 is driven to rotate manually or automatically.

[0041] In a specific structure, in order to realize automatic rotation, the turntable 200 is connected to a motor. The motor can be a stepper motor or a servo motor, which can provide precise control and stable rotation speed. The motor is connected to the turntable 200 through a transmission mechanism (such as gears, belts, etc.), thereby driving the turntable to rotate.

[0042] At the same time, in order to meet different scenarios and needs, the turntable 200 is also designed to be manually rotated. In manual mode, the operator can rotate the handle or knob on the turntable 200 to achieve rotation, which is suitable for flexible adjustment or operation without power supply.

[0043] Example 6: Figure 2 As shown, the top of the glue storage tank 100 is covered with a transparent cover plate 102 .

[0044] The design of the transparent cover 102 allows the operator to directly observe the glue situation in the glue storage tank 100, including the amount, color, state, etc. of the glue, without opening the cover. At the same time, the sealing and protective effects of the cover help maintain the internal environment of the glue storage tank 100.

[0045] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
