Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a syringe booster device with a layered handle. Background Technology

[0002] In recent years, cosmetic dermal filler procedures have become increasingly popular. During the procedure, a syringe is used to insert filler into the patient's skin. Therefore, there is a need for a more aesthetically pleasing injection device to reduce tension during the procedure. However, conventional syringes are manufactured according to specific medical device standards, resulting in limited design variation. Therefore, finding a more aesthetically pleasing syringe auxiliary device has become a key area for improvement.

[0003] In skin filler surgery, it is often necessary to operate the syringe with one hand. The needle tip is first inserted into the skin, and repeated aspiration is performed to determine if a blood vessel has been punctured. Only after confirming that no blood vessel has been punctured can the filler be injected. However, in cases with a high volume of surgeries, this repeated aspiration can become a burden for the surgeon, easily causing hand fatigue and affecting the surgical outcome. For example, Chinese Patent CN221751783U discloses an injection and aspiration device with an aspiration limiting block (i.e., the retaining ring in this application) and a pusher finger support (i.e., the handle in this application). When attaching it to the syringe, aspiration can be performed with one hand. When using this device to operate the plunger, the thumb is typically placed under the plunger head, while the other fingers rest on the aspiration limiting block, preventing the fingers from touching the upper surface of the pusher handle. Therefore, this patented device only has a soft rubber layer on the lower surface of the handle, while the upper surface of the handle does not have a soft rubber layer. However, hand size varies from person to person. Some people, when using the device, will forgo the suction limit block and instead place their fingers on the upper surface of the handle to operate the plunger. In this case, since the upper surface of the handle lacks a soft rubber layer, the comfort is greatly reduced, and it cannot meet the needs of prolonged use.

[0004] Furthermore, current soft rubber layers are generally made of elastic materials (such as TPE, Thermoplastic Elastomer, etc.) and attached to the surface of a rigid plastic support frame using an injection molding process. However, the booster handle is relatively thin and often has an ergonomic curve, making it prone to deformation during injection due to the impact. Therefore, current booster handles are typically injected only on one side, while the other side requires a template for positioning and preventing deformation. Since the template occupies the injection space on the other side, preventing the formation of a soft rubber layer there, there are currently no booster devices on the market that have soft rubber layers applied to both sides of the handle. Utility Model Content

[0005] This invention aims to solve the problems of the prior art by providing a syringe propulsion device with soft rubber layers on both the upper and lower surfaces of the handle, which greatly improves the comfort of use, and the distinct layers are more aesthetically pleasing and can reduce the tension during surgery.

[0006] This utility model provides a syringe propulsion device with a layered handle, comprising a sleeve with a slot, a handle at one end of the sleeve, an upper soft rubber layer and a lower soft rubber layer respectively on the upper and lower surfaces of the handle, with a side edge of the handle sandwiched between the upper and lower soft rubber layers. In this way, the handle body forms a distinct three-layer structure of upper soft rubber layer, side edge, and lower soft rubber layer, which is aesthetically pleasing and greatly reduces tension during surgery; moreover, the soft rubber layers on both the upper and lower surfaces of the handle can adapt to different usage habits, greatly improving user comfort.

[0007] Preferably, the sides of the handle are of uniform thickness. This makes the layered structure more distinct and aesthetically pleasing, while also ensuring structural compactness and facilitating processing and use.

[0008] Preferably, the lower surface of the handle has an ergonomic curvature, and its side has a groove; the lower soft rubber layer is attached to the lower surface of the handle, and its side is embedded in the groove. In this way, even with the curvature of the lower surface of the handle, a lower soft rubber layer can still be formed, providing a distinct layer and meeting usage requirements.

[0009] Preferably, the upper surface of the handle is provided with a positioning post, and the handle has an injection channel connecting the upper and lower surfaces. In this way, a soft rubber layer can be formed on both the upper and lower surfaces of the handle with a single injection, and the handle will not deform due to the impact of the injection.

[0010] Preferably, the positioning posts and channels are symmetrically distributed on both sides of the handle. This makes the overall shape more aesthetically pleasing and the overall structure more reasonable and compact.

[0011] Preferably, the handle has a surround around the plunger rod, which is integrally formed on the upper surface of the handle. This prevents the plunger rod from impacting and wearing down the soft rubber layer on the upper surface, thus improving service life.

[0012] Preferably, the back of the handle is provided with a thinning hole. This prevents uneven thickness of the handle due to thermal expansion and contraction of the material during injection molding, ensuring that the sides of the handle are of uniform thickness and that the layering effect is more obvious.

[0013] Preferably, the sleeve surface is provided with a soft rubber layer. This improves the user comfort at the sleeve location.

[0014] Preferably, a retaining ring is provided at the end of the sleeve away from the handle, and the surface of the retaining ring is provided with a soft rubber layer. This improves the comfort of use at the retaining ring.

[0015] Preferably, two soft rubber baffles are provided between the handle and the retaining ring, and the two soft rubber baffles are symmetrically distributed on both sides of the slot. This prevents discomfort to the hand when inserting the syringe.

[0016] The syringe booster device with a layered handle provided by this utility model has at least the following advantages:

[0017] 1. This utility model has a distinct and aesthetically pleasing appearance, greatly reducing the tension during surgery and facilitating its widespread adoption. Furthermore, the soft rubber layer on both the upper and lower surfaces of the handle significantly improves user comfort and caters to different usage habits.

[0018] 2. This utility model only requires one injection of glue to create a soft glue layer on both the upper and lower surfaces of the handle, and the handle will not deform due to the impact of the glue injection. Attached Figure Description

[0028] like Figure 1 , Figure 2 As shown, this utility model discloses a syringe booster device with a layered handle, comprising a sleeve 1 with a slot 11. The slot 11 consists of three through parts: a plunger rod groove for the plunger rod 6 to pass through, a flange slot for inserting the syringe barrel flange 51, and a syringe barrel groove for inserting the syringe barrel 5. A handle 2 is provided at one end of the sleeve 1. The handle 2 has sides 21 of uniform thickness, and its upper and lower surfaces are respectively provided with an upper soft rubber layer 22 and a lower soft rubber layer 23. The lower surface of the handle 2 has an ergonomic curvature, and its side has a groove 27; the lower soft rubber layer 23 is attached to the lower surface of the handle 2, and its side is embedded in the groove 27.

[0029] The upper surface of the handle 2 is provided with a positioning post 24, and the handle 2 has an injection channel 25 that connects the upper and lower surfaces. The positioning post 24 and the channel 25 are symmetrically distributed on both sides of the handle 2. The handle 2 is provided with a retaining ring 26 surrounding the plunger rod 6, which is integrally formed on the upper surface of the handle 2. The back of the handle 2 is provided with a thinning hole 28. The surface of the sleeve 1 is provided with a sleeve soft rubber layer 12. A retaining ring 3 is provided at the end of the sleeve 1 away from the handle 2, and the surface of the retaining ring 3 is provided with a retaining ring soft rubber layer 31. Two soft rubber baffles 4 are supported between the handle 2 and the retaining ring 3, and the two soft rubber baffles 4 are symmetrically distributed on both sides of the slot 11.

[0030] like Figure 3 As shown, the sleeve 1, handle 2 body, and retaining ring 3 are integral structures, injection molded from hard plastic material (such as ABS). The retaining wall 26 and positioning post 24 are also integrally formed on the handle 2 body. The channel 25 and thinning hole 28 are opened on the handle 2 body.

[0031] like Figure 4As shown, the upper soft rubber layer 22, lower soft rubber layer 23, sleeve soft rubber layer 12, retaining ring soft rubber layer 31, and soft rubber baffle 4 are an integral structure, made of elastic soft rubber materials such as TPE by injection molding. The upper soft rubber layer 22 and lower soft rubber layer 23 are connected together by channel soft rubber 29 located in the injection channel 25.

[0032] Because ABS and TPE materials have naturally different colors and appearances, the upper soft rubber layer 22, the handle side 21, and the lower soft rubber layer 23 of this invention form a distinct three-layer structure with clear layers and enhanced aesthetics. Simultaneously, it overcomes existing technical biases by using the positioning post 24 and the glue injection channel 25 to cover both the upper and lower surfaces of the handle 2 with a single glue injection, resulting in greater comfort and catering to different user habits. Of course, using this invention, the handle can also be made with a 5-layer or 7-layer structure, which will not be elaborated upon here.

[0033] The present invention relates to a syringe booster device with a layered handle, the manufacturing method of which includes the following steps:

[0034] Step 1: Put Figure 3 The rigid skeleton shown has been injection molded.

[0035] Step 2: Use the template to hold the upper end face of the positioning post 24, and inject liquid soft glue from below the handle 2 so that it is distributed on the lower surface of the handle 2, the outer surface of the sleeve 1, the outer surface of the retaining ring 3, and flows through the channel 25 to be distributed on the upper surface of the handle 2.

[0036] Step 3: Once the liquid soft glue has solidified, the process is complete.

[0037] The manufacturing method of this utility model can ensure that the handle 2 will not be deformed due to impact, and at the same time, only one injection of glue is needed to wrap the entire soft rubber layer on the upper and lower surfaces of the handle 2, which greatly improves the comfort during use.

[0038] The method of using this syringe compound booster device of the present invention is as follows:

[0039] First, such as Figure 5 As shown, the device of this utility model is installed on a syringe, with the syringe barrel 5, syringe barrel flange 51, and plunger rod 6 located in the slot 11.

[0040] When pushing the plunger rod 6 forward, the thumb presses on the upper surface of the head of the plunger rod 6, and the other fingers rest on the lower surface of the handle 2, respectively located on both sides of the slot 11. By applying force with the fingers, the plunger rod 6 can be pushed.

[0041] When pulling the plunger rod 6 back, the thumb rests on the lower surface of the head of the plunger rod 6, and the other fingers rest on the upper surface of the handle 2 or the upper surface of the retaining ring 3. By applying force with the fingers, the plunger rod 6 can be pulled back.

[0042] In the above usage methods, the fingers come into contact with the device through elastic soft rubber, which greatly reduces finger fatigue, meets the needs of long-term use in cosmetic skin filler surgery, and is conducive to its promotion.

[0043] When the syringe needs to be replaced, this device can be easily removed from the syringe and inserted into another syringe. The rigid frame ensures that it will not deform even after multiple insertions and removals, thus meeting the needs of long-term use. In addition, the soft rubber parts ensure that hands will not be injured during insertion and removal, resulting in good performance.
