Description

Technical Field

[0001] This invention relates to a pre-filled gel syringe and its use, belonging to the technical field of stem cell syringe equipment. Background Technology

[0002] Stem cells are an important biological resource. In recent years, stem cell therapy has developed rapidly as an emerging medical technology, showing significant therapeutic effects on various diseases, such as osteoarthritis, graft-versus-host disease, systemic lupus erythematosus, diabetes, and cardiovascular diseases. Stem cells have also achieved good results in treating local skin damage. Stem cells and their secreted factors can build collateral circulation, alleviate ischemic symptoms, inhibit inflammation, regulate immunity, and activate and recruit autologous stem cells for repair.

[0003] However, the syringes currently on the market have a relatively simple structure and only have the function of injection. When injecting the gel, other equipment is needed to spread the gel. Since the cells in the gel are expensive and the gel components are sterile, using other equipment to spread the gel can easily lead to waste such as contamination. There is an urgent need for a pre-filled gel syringe to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a syringe for pre-filling and using gel, thereby solving the problems mentioned in the background. This invention designs a multifunctional syringe structure that not only allows for gel injection but also facilitates rapid spreading of the injected gel by staff, preventing waste such as contamination.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a syringe for pre-filling and using gel, comprising an injection tube body, an inner thread connector, an outer thread connector, and a usage connector. A rubber piston is inserted inside the injection tube body, and a push-pull rod is installed at the upper end of the rubber piston. A tube head is integrally fixed at the middle of the lower end of the injection tube body. The inner thread connector is installed outside the tube head. The outer thread connector is screwed onto the lower end of the inner thread connector by a thread principle. A usage connector is horizontally fixed at the lower end of the outer thread connector. Multiple small holes are opened from left to right at the lower end of the usage connector. A silicone sheet is provided at the rear end of the usage connector.

[0006] Furthermore, the upper edge of the injection tube is integrally provided with a rolled outer edge.

[0007] Furthermore, a milliliter scale is provided on the left side of the injection tube.

[0008] Furthermore, the external threaded connector communicates internally with the connector in use.

[0009] Furthermore, the injection tube is filled with cell gel.

[0010] Furthermore, the injection tube is made of polypropylene, the rubber piston is a halogenated butyl rubber piston, and the push rod is made of polyethylene.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a pre-filled gel syringe. Because this utility model adds a push-pull rod, injection tube body, tube head, inner thread connector, outer thread connector, usage connector, small hole, rubber piston, and silicone sheet, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. The design of a multi-functional syringe structure can not only inject gel, but also facilitate the staff to quickly spread the injected gel, and will not easily cause waste such as contamination.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a syringe for pre-filling and using gel, including an injection tube body 2, an inner thread connector 6, an outer thread connector 7, and a usage connector 8. A rubber piston 11 is inserted inside the injection tube body 2, and a push-pull rod 1 is installed on the upper end of the rubber piston 11. A tube head 5 is integrally fixed in the middle of the lower end of the injection tube body 2. The inner thread connector 6 is installed outside the tube head 5. The outer thread connector 7 is screwed onto the lower end of the inner thread connector 6 by means of a thread. The usage connector 8 is horizontally fixed at the lower end of the outer thread connector 7. Multiple small holes 9 are opened from left to right at the lower end of the usage connector 8. A silicone sheet 10 is provided at the rear end of the usage connector 8. This design solves the problem that the existing syringes on the market have a relatively simple structure and only have an injection function.

[0020] As the first embodiment of this utility model: the upper edge of the injection tube body 2 is integrally provided with an outer rolled edge 3, and a milliliter scale 4 is provided on the left side of the injection tube body 2. The external thread connector 7 and the user connector 8 are internally connected. The added internal thread connector 6, user connector 8, external thread connector 7 and injection tube body 2 are all made of the same polypropylene material. Due to the setting of the internal thread connector 6 and external thread connector 7, it is convenient to disassemble the user connector 8. Therefore, when the device is not in use, a polyethylene rubber cap (such as...) can be sealed and installed at the lower end of the internal thread connector 6. Figure 3 The injection tube 2 is filled with cell gel. The injection tube 2 is made of polypropylene, the rubber piston 11 is a halogenated butyl rubber piston, and the push-pull rod 1 is made of polyethylene. The added cell gel contains protective agents that safeguard cell viability, such as albumin and dimethyl sulfoxide. Stem cells must be active for the drug to be effective. The finished product is generally stored long-term at -80 degrees Celsius. After thawing, the gel is temporarily stored at 4 degrees Celsius.

[0021] As a second embodiment of this utility model: The syringes selected in this utility model are sterile (EO sterilized), pyrogen-free, graduated, and tightly sealed, with volumes of 3ml, 5ml, and 10ml. The polyethylene rubber cap, inner thread connector 6, usage connector 8, and outer thread connector 7 are all sterile and pyrogen-free. When using, the frozen gel is thawed in a water bath at 37±2℃ for 5 minutes. The polyethylene rubber cap is removed, and the outer thread connector 7 is tightened at the lower end of the inner thread connector 6. The usage connector 8 has different lengths. The scenarios in which the gel is used are when the wound is relatively large, such as diabetic foot ulcers, pressure sores, urticaria, and other skin diseases. Squeezing the push-pull rod 1 and the rubber piston 11 allows the gel to flow from the tube head 5, inner thread connector 6, outer thread connector 7, and usage connector 8. Finally, the gel is evenly distributed to the wound surface through a row of small holes 9 at the bottom of the usage connector 8. At the same time, the silicone sheet 10 at the rear can directly scrape or compact the gel on the wound surface. Finally, a sterile dressing of appropriate size is applied and bandaged for 30 minutes.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
