Description

Technical Field

[0001] This utility model relates to the field of filling technology for auxiliary materials, specifically a filling and dispensing head for the production of sodium hyaluronate dressings. Background Technology

[0002] Sodium hyaluronate dressing is a medical product, which is the common hyaluronic acid. Sodium hyaluronate is a polysaccharide that exists naturally in the human body. It has a strong water retention capacity and can absorb 1,000 times its own weight in water.

[0003] When used as a medical adjuvant, sodium hyaluronate needs to be quantitatively packaged and stored in dressing bags. However, sodium hyaluronate is a jelly-like gel-like fluid, and the amount packaged is difficult to control using common flow equipment. Furthermore, due to its high viscosity, it tends to form lumps in the pipes during the packaging process, which can easily cause blockages. Utility Model Content

[0004] The purpose of this invention is to provide a filling and dispensing head for the production of sodium hyaluronate dressings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The quantitative filling head is elastically clamped and installed on a container holding sodium hyaluronate dressings. The quantitative filling head includes a quantitative component, an inlet end connected to the outlet on the container, and an inclined filling pipe for filling the dressing bag. The quantitative component includes an outer spherical frame clamped at the lower end of the container. A rotating ball is rotatably installed inside the outer spherical frame. Multiple sets of material grooves are arranged in a circumferential array on the arcuate outer wall of the rotating ball. The port positions of the material grooves correspond to the upper port of the inlet end and the inclined filling pipe. An ejection component is provided on the inclined filling pipe for opening and clamping the port of the dressing bag.

[0007] Preferably, a lower clamping frame is elastically installed at the lower end of the material tank, and the outer ball frame is clamped between the lower end of the material tank and the lower clamping frame, with the inclined injection pipe passing through the middle through hole of the lower clamping frame.

[0010] Preferably, the lower clamping frame and the lower outer wall of the material tank are provided with a slot, and the outer ball frame is provided with a locking block that engages with the slot.

[0011] Preferably, the ejection assembly includes ejector rods and pull ropes. A riser is installed inside the lower vertical pipe of the inclined injection pipe. The upper end of the riser extends above the middle inclined pipe of the inclined injection pipe. Multiple sets of ejector rods are elastically installed on the side wall of the lower vertical pipe port, arranged in a circumferential array. One end of the ejector rod extends to the outside of the vertical pipe, and the other end of the ejector rod is connected to the pull rope, which extends along the riser.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution:

[0023] Example 1: A quantitative filling head for producing sodium hyaluronate dressings. The quantitative filling head is elastically clamped and installed on a material tank 1 containing sodium hyaluronate dressings. The quantitative filling head includes a quantitative component, an inlet end 14 connected to the outlet 2 on the material tank 1, and an inclined filling pipe 7 for filling dressing bags 6. The quantitative component includes an outer ball frame 4 clamped at the lower end of the material tank 1. A lower clamping frame 3 is elastically installed at the lower end of the material tank 1. The outer ball frame 4 is clamped between the lower end of the material tank 1 and the lower clamping frame 3. The inclined filling pipe 7 passes through the middle through hole of the lower clamping frame 3. A pair of T-shaped pull rods 10 are provided on the lower clamping frame 3. The upper end of the pull rod 10 passes through the lower end of the material tank 1, and a first spring 11 is sleeved on the pull rod 10.

[0024] Through the cooperation of the first spring 11 and the pull rod 10, the lower clamping frame 3 is elastically installed at the lower end of the material tank 1, and then the elastic force of the first spring 11 is used to clamp the outer ball frame 4, so that the feed end 14 is kept tightly pressed and connected with the discharge port 2.

[0025] A rotating ball 5 is rotatably installed inside the outer ball frame 4. The outer ball frame 4 is composed of a pair of hemispherical frames connected by bolts. A motor 9 is installed on the outer ball frame 4. The rotating ball 5 rotates to fit against the inner arc of the outer ball frame 4. A rotating shaft 18 connected to the output end of the motor 9 is installed on the rotating ball 5.

[0026] By setting the outer ball frame 4 as a pair of hemispherical frames connected by bolts, the rotating ball 5 can be easily disassembled and replaced. Multiple sets of rotating balls 5 with the same outer diameter but different material trough 19 capacities can be prefabricated to adapt to different filling volume requirements. With the cooperation of the motor 9 and the rotating shaft 18, the rotating ball 5 is driven to rotate, realizing rotating material cutting and dropping.

[0027] The outer arc of the rotating ball 5 is provided with multiple sets of material troughs 19 arranged in a circular array. The port positions of the material troughs 19 correspond to the upper port of the feed end 14 and the inclined injection pipe 7.

[0028] The material trough 19 is used to limit the filling volume, and the inclined filling pipe 7 is used to achieve the purpose of material pouring.

[0029] Working principle: First, by connecting the inlet 14 and the outlet 2, the installation of pipes and control valves is avoided to prevent blockage. The gel-like sodium hyaluronate dressing can fall directly into the material tank 19. During the rotation of the rotating ball 5, the material tank 19 is rotated and misaligned. During the misalignment, the block-shaped sodium hyaluronate dressing is rotated and cut to achieve precise material cutting and avoid the material from sticking together. As it rotates, the material tank 19 aligns with the inclined filling pipe 7. Then, gravity is used to fill the dressing bag 6 along the inclined filling pipe 7. At the interval of rotation, the sodium hyaluronate dressing at the lower end of the material tank 1 is sealed, so that the filling and metering head can be adapted to the metering of gel-like raw materials.

[0030] Example 2: Based on Example 1, a slot 13 is provided on the lower outer wall of the lower clamping frame 3 and the material tank 1, and a locking block 12 is provided on the outer ball frame 4 to engage with the slot 13.

[0031] By setting the cooperation between the slot 13 and the block 12, the position of the outer ball frame 4 is limited to ensure its accuracy and avoid vibration and displacement during rotation, material dropping, etc.

[0032] An ejection assembly for opening and clamping the port of the dressing bag 6 is provided on the inclined infusion pipe 7. The ejection assembly includes a push rod 16 and a pull rope 15. A riser 8 is provided inside the lower vertical pipe of the inclined infusion pipe 7. The upper end of the riser 8 extends above the middle inclined pipe of the inclined infusion pipe 7. Multiple sets of push rods 16 are elastically installed on the side wall of the port of the lower vertical pipe of the inclined infusion pipe 7 in a circumferential array. One end of the push rod 16 extends to the outside of the vertical pipe, and the other end of the push rod 16 is connected to the pull rope 15. The pull rope 15 extends along the riser 8. A second spring 17 is sleeved on the end of the push rod 16 located on the outside of the vertical pipe. A push ball is provided on the outside of the push rod 16 and abuts against the inner wall of the port of the dressing bag 6. The second spring 17 is pressed between the push ball and the outer wall of the vertical pipe. The multiple sets of pull ropes 15 connected to the push rods 16 extend smoothly into the riser 8. The multiple sets of pull ropes 15 are tied to a pull ring located on the upper outside of the riser 8.

[0033] The second spring 17 enables the top rod 16 to be installed elastically. Since the second spring 17 is located on the outside of the vertical pipe, it will not affect the material drop. At the same time, the pull rope extending laterally between the vertical pipe and the riser 8 can cut the gel-like sodium hyaluronate dressing, preventing it from clogging or sticking inside the pipe and ensuring stable material drop and pouring.

[0034] When installing the dressing bag 6, open the bag opening and pull the pull rope 15 through the pull ring, causing the top rod 16 to retract and squeeze the second spring 17. At this time, put the dressing bag 6 on the outside of the lower end port of the vertical tube, release the pull ring, and under the restoring force of the second spring 17, the top rod 16 extends outward and squeezes and opens the bag opening of the dressing bag 6. After quantitative infusion, pull the pull ring again to retract the top rod 16, and the dressing bag 6 loses support, making it easy to fall off the vertical tube.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
