Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable cosmetic dressing bag. Background Art

[0002] With the rapid development of medical cosmetic technology, hyaluronic acid (HA) has become a core material in the field of micro-plastic surgery such as facial filling and contour modification due to its excellent biocompatibility, degradability and filling and shaping effects. In clinical practice, disposable sterile treatment packs are usually used for hyaluronic acid injection treatment, which can improve the convenience and safety of medical operations and significantly reduce medical costs. However, there are still some shortcomings, as described below:

[0003] During the injection of hyaluronic acid, after the needle pierces the human tissue, it is necessary to withdraw the needle first. After ensuring that the needle has not entered the blood vessel by mistake, the hyaluronic acid can be injected. This operation method can prevent hyaluronic acid from entering the blood circulation and causing embolism. However, the molecular structure of hyaluronic acid is dense and has strong viscoelasticity. During the withdrawal operation, the negative pressure suction force formed in the syringe is difficult to act quickly on the needle site, resulting in a relatively slow blood return speed after the withdrawal action, which prolongs the patient's treatment time.

[0004] Therefore, during the injection operation of hyaluronic acid injection, how to increase the blood return rate after the withdrawal action and reduce the patient's treatment time is a technical problem that needs to be urgently solved in the existing technology.

[0005] The rapid and safe installation of components is an urgent problem to be solved in the current steel structure construction. Utility Model Content

[0006] The purpose of the utility model is to provide a disposable cosmetic dressing bag to address the problem in the prior art that the molecular structure of hyaluronic acid is dense and has strong viscoelasticity, and the negative pressure suction force formed in the syringe during the withdrawal operation is difficult to act quickly on the needle tip, resulting in a relatively slow blood return speed after the withdrawal action, which prolongs the patient's treatment time.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A disposable cosmetic dressing bag comprises a dressing bag body, wherein a plurality of medical articles for hyaluronic acid injection are placed in the dressing bag body, wherein the medical articles comprise a hyaluronic acid syringe, and the hyaluronic acid syringe comprises a needle component, a syringe and a push injection component.

[0009] The needle component includes a puncture needle, a drainage tube and a negative pressure tube. The drainage tube is inserted into the liquid outlet of the syringe. The puncture needle and the negative pressure tube are respectively arranged at both ends of the drainage tube. The negative pressure tube extends into the accommodating cavity of the syringe. The drainage tube and the puncture needle are connected with the negative pressure tube. A through hole is also arranged on the drainage tube, and the through hole is used to connect the drainage tube with the accommodating cavity of the syringe.

[0010] The push injection component includes a plug and a plug rod, the plug is clamped in the syringe, the plug rod is connected to the plug, and the plug rod is used to push / pull the plug to slide in the syringe; a linear cavity is also provided along the central axis of the plug and the plug rod, and the linear cavity is used to accommodate the negative pressure tube.

[0011] Preferably, the through hole is arranged on a side of the drainage tube facing the syringe accommodating chamber.

[0012] Preferably, the length of the liquid introduction tube is smaller than the length of the liquid outlet nozzle of the syringe.

[0013] Preferably, a first one-way valve is provided in the through hole, and the first one-way valve is used to open the through hole when a positive pressure environment is formed in the syringe, and to close the through hole when a negative pressure environment is formed in the syringe.

[0014] Preferably, the length of the negative pressure tube is greater than 3 / 4 of the length of the syringe.

[0015] Preferably, a second one-way valve is also provided at the connection portion between the negative pressure tube and the drainage tube, and the second one-way valve is used to close the internal cavity of the negative pressure tube when a positive pressure environment is formed in the syringe, and to open the internal cavity of the negative pressure tube when a negative pressure environment is formed in the syringe.

[0016] Preferably, the drainage tube and the puncture needle are detachably connected.

[0017] Preferably, the puncture needle and the liquid outlet nozzle of the syringe are threadedly connected.

[0018] Preferably, an observation area is also provided on the syringe, the length of the observation area matches the length of the negative pressure tube, and the observation area is used to magnify the image of the negative pressure tube.

[0019] Preferably, the medical supplies also include disinfectant, large sterile cotton swabs, oval-neck treatment towels, disposable curved treatment trays, and gauze.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] 1. In the disposable cosmetic dressing pack described in the utility model, when the hyaluronic acid syringe is used for the back-drawing operation, the negative pressure tube can directly transfer the negative pressure suction force formed in the syringe to the drainage tube, so that the blood can smoothly enter the negative pressure tube under the action of the negative pressure suction force, thereby avoiding the hyaluronic acid in the syringe from hindering the flow of blood, thereby effectively reducing the waiting time after the back-drawing action and improving the efficiency of injection treatment;

[0022] 2. In the disposable cosmetic dressing bag described in the utility model, a first one-way valve is provided in the through hole, and the first one-way valve is used to open the through hole when a positive pressure environment is formed in the syringe, and to close the through hole when a negative pressure environment is formed in the syringe. This structural setting can prevent the hyaluronic acid in the syringe from entering the drainage tube through the through hole during the withdrawal operation, thereby preventing the blood from flowing into the negative pressure tube. This further reduces the waiting time after the withdrawal action and improves the efficiency of injection treatment. On the other hand, when a negative pressure environment is formed in the syringe, the first one-way valve closes the through hole, which can make the negative pressure suction force more concentrated inside the drainage tube. This further increases the speed of blood flowing back to the negative pressure tube and improves the efficiency of injection treatment.

[0023] 3. The disposable cosmetic dressing pack described in the present invention can prevent hyaluronic acid from entering the negative pressure tube when a positive pressure environment is formed in the syringe by closing the internal cavity of the negative pressure tube through the second one-way valve during the push injection operation. In this way, when performing puncture injection operations at multiple locations without replacing the needle component, the total amount of hyaluronic acid entering the negative pressure tube can be effectively reduced. Furthermore, when the puncture needle and the drainage tube are filled with hyaluronic acid, the speed at which blood flows into the negative pressure tube can be accelerated after the back-drawing action, thereby further improving the practicality of the present invention in actual use. On the other hand, adopting this structural setting can reduce the waste of hyaluronic acid during the push injection process and further improve the effective utilization rate of the hyaluronic acid agent.

Such terms are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0033] Example 1: Figure 1 and Figure 2 As shown, the disposable cosmetic dressing pack of the utility model comprises a dressing pack body, wherein a plurality of medical articles for hyaluronic acid injection are placed in the dressing pack body, wherein the medical articles comprise a hyaluronic acid syringe 1, wherein the hyaluronic acid syringe 1 comprises a needle component 2, a syringe 3 and a push injection component 4.

[0034] The needle component 2 includes a puncture needle 5, a drainage tube 6 and a negative pressure tube 7. The drainage tube 6 is inserted into the liquid outlet of the syringe 3. The puncture needle 5 and the negative pressure tube 7 are respectively arranged at both ends of the drainage tube 6. The negative pressure tube 7 extends into the accommodating cavity of the syringe 3. The drainage tube 6 and the puncture needle 5 are connected with the negative pressure tube 7. A through hole 8 is also arranged on the drainage tube 6, and the through hole 8 is used to connect the drainage tube 6 with the accommodating cavity of the syringe 3.

[0035] The push injection component 4 includes a plug 9 and a plug rod 10, the plug 9 is clamped in the syringe 3, the plug rod 10 is connected to the plug 9, and the plug rod 10 is used to push / pull the plug 9 to slide in the syringe 3; a linear cavity 11 is also provided along the central axis of the plug 9 and the plug rod 10, and the linear cavity 11 is used to accommodate the negative pressure tube 7.

[0036] When using the disposable cosmetic dressing bag described in the present invention and performing a backdrawing operation using the hyaluronic acid syringe 1, the negative pressure tube 7 can directly transfer the negative pressure suction force formed in the syringe 3 to the drainage tube 6. In this way, blood can smoothly enter the negative pressure tube 7 under the action of the negative pressure suction force, thereby preventing the hyaluronic acid in the syringe 3 from obstructing the flow of blood, thereby effectively reducing the waiting time after the backdrawing action and improving the efficiency of injection treatment.

[0037] Specifically, in this embodiment, the needle component 2 is an integral structure; in actual use, after the syringe 3 is used to extract hyaluronic acid, the negative pressure tube 7 is inserted along the liquid outlet of the syringe 3, and the puncture needle 5 is connected to the liquid outlet of the syringe 3 to complete the assembly of the new hyaluronic acid syringe 1; it should be noted that the height of the hyaluronic acid filled in the syringe 3 exceeds the end of the negative pressure tube 7;

[0038] During the hyaluronic acid injection operation, the puncture needle 5 is first kept in a state where there is no hyaluronic acid agent inside for puncture. When the puncture needle 5 reaches the target depth, the plug rod 10 is pulled back to form a negative pressure environment in the syringe 3. At this time, the negative pressure suction force can be directly transmitted to the drainage tube 6 through the negative pressure tube 7; if the puncture needle 5 pierces the blood vessels of human tissue, blood flows back into the negative pressure tube 7, and the operator can determine whether the puncture is successful by observing whether there is blood in the negative pressure tube 7.

[0039] As a preferred embodiment, based on the above method, further, the through hole 8 is arranged on the side of the drainage tube 6 facing the accommodating cavity of the syringe 3. With this structural arrangement, hyaluronic acid can enter the drainage tube 6 more smoothly during the push injection operation, thereby improving the practicality of the present invention in actual use.

[0040] As a preferred embodiment, based on the above method, further, the length of the liquid introduction tube 6 is less than the length of the liquid outlet of the syringe 3. With this structural setting, the hyaluronic acid can be better concentrated to the through hole 8 during the push injection operation, thereby reducing the residual amount of hyaluronic acid in the syringe 3 and improving the effective use rate of the hyaluronic acid.

[0041] As a preferred embodiment, based on the above method, further, the length of the negative pressure tube 7 is greater than 3 / 4 of the length of the syringe 3.

[0042] Example 2: Figure 1 and Figure 2 As shown, the disposable cosmetic dressing bag described in the utility model is based on the above method, and further, a first one-way valve 12 is arranged in the through hole 8, and the first one-way valve 12 is used to open the through hole 8 when a positive pressure environment is formed in the syringe 3, and to close the through hole 8 when a negative pressure environment is formed in the syringe 3. With this structural setting, it is possible to avoid the hyaluronic acid in the syringe 3 entering the drainage tube 6 through the through hole 8 during the withdrawal operation, thereby preventing the blood from flowing into the negative pressure tube 7, thereby further reducing the waiting time after the withdrawal action and improving the efficiency of injection treatment; on the other hand, the first one-way valve 12 closes the through hole 8 when a negative pressure environment is formed in the syringe 3, so that the negative pressure suction force is more concentrated inside the drainage tube 6, thereby further increasing the speed of blood returning to the negative pressure tube 7 and improving the efficiency of injection treatment.

[0043] As a preferred embodiment, based on the above method, further, a second one-way valve 13 is provided at the connection portion between the negative pressure tube 7 and the drainage tube 6. The second one-way valve 13 is used to close the internal cavity of the negative pressure tube 7 when a positive pressure environment is formed in the syringe 3, and to open the internal cavity of the negative pressure tube 7 when a negative pressure environment is formed in the syringe 3.

[0044] Specifically, in this embodiment, the internal cavity of the negative pressure tube 7 is closed by the second one-way valve 13 during the push injection operation, so that hyaluronic acid can be prevented from entering the negative pressure tube 7 when a positive pressure environment is formed in the syringe 3. In this way, when performing multi-site puncture injection operations without replacing the needle component 2, the total amount of hyaluronic acid entering the negative pressure tube 7 can be effectively reduced. Furthermore, when the puncture needle 5 and the drainage tube 6 are full of hyaluronic acid, the speed of blood flowing into the negative pressure tube 7 can be accelerated after the back suction action, thereby further improving the practicality of the present invention in actual use. On the other hand, adopting this structural setting can reduce the waste of hyaluronic acid during the push injection process, and further improve the effective utilization rate of the hyaluronic acid agent.

[0045] Example 3: Figure 1 and Figure 2 As shown, the disposable cosmetic dressing bag described in the present invention is based on the above method, and further, the drainage tube 6 and the puncture needle 5 are detachably connected.

[0046] Specifically, in this embodiment, a plug-in column tube is provided on the puncture needle 5. When the two are connected, the plug-in column is inserted into the inner cavity of the drainage tube 6. With this structural setting, the puncture needle 5 of different specifications and models can be easily replaced, which further improves the practicality of the new model in actual use.

[0047] As a preferred embodiment, based on the above method, further, the puncture needle 5 is threadedly connected with the liquid outlet of the syringe 3. With this structural setting, the stability of the assembly connection between the needle component 2 and the syringe 3 can be improved.

[0048] As a preferred embodiment, based on the above method, further, the syringe 3 is provided with an observation area, the length of which matches the length of the negative pressure tube 7, and the observation area is used to magnify the image of the negative pressure tube 7. With this structural setting, it is more convenient for the operator to observe whether the blood enters the negative pressure tube 7, thus further improving the practicality of the new model in actual use.

[0049] Example 4: Figure 1 and Figure 2 As shown, the disposable cosmetic dressing bag described in the utility model is based on the above method, and further, the medical items also include disinfectant, large sterile cotton swabs, oval neckline treatment towels, disposable treatment curved trays, and gauze.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
