Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a syringe composite boosting device and a manufacturing method thereof. BACKGROUND

[0002] In recent years, cosmetic skin filler surgery has become increasingly popular. When performing skin filler surgery with a syringe, the syringe needs to be operated with one hand, the needle tip is first pierced into the skin, and repeated suction is performed to determine whether the blood vessel is pierced, and only after it is ensured that the blood vessel is not pierced, can the injection be performed to complete the filling. In the case of more operations, repeated pulling will become a burden for the operator, which is easy to cause hand fatigue, thereby affecting the effect of the operation.

[0003] At present, some flanges of injection cylinders are equipped with boosting devices for hand holding, which make it more convenient for the fingers to pull the piston rod during injection. In order to make the fingers more comfortable, the boosting device is provided with a soft rubber body on the finger contact surface. The current soft rubber body generally adopts an elastic material (such as TPE, Thermoplastic Elastomer, etc.) to be attached to the surface of a supporting skeleton made of hard plastic material through a glue injection processing technology. The handle part of the boosting device is relatively thin, and often has an ergonomic arc, so that the handle part is easily deformed due to the impact force of glue injection during glue injection. Therefore, the handle part of the current boosting device is often only glued on one side, and the other side needs to be stopped and positioned by a mold plate during glue injection to ensure that the handle part will not be deformed. Since the mold plate occupies the glue injection space on the other side, the soft rubber body cannot be formed on the side, so there is no boosting device that glues the soft rubber body on both sides of the handle part.

[0004] In addition, the current soft rubber body and hard plastic skeleton are basically two independent structures, which are combined only by the binding capacity of the two materials. After a long time of use, the material ages, and the soft rubber body is easy to fall off, affecting the use effect. SUMMARY

[0005] The present application solves the above-mentioned problems of the prior art, and provides a syringe composite boosting device and a manufacturing method thereof. The soft rubber body is distributed on the upper and lower surfaces of the handle part, and the soft rubber bodies at different positions are integrated, so that the boosting device is wrapped by the soft rubber body at different positions, and the hand feeling is more comfortable. In addition, the soft rubber body and the hard skeleton are combined more tightly, and are not easy to fall off, and will not deform the handle part during glue injection.

[0006] The injector composite boosting device comprises a hard framework and a soft gel body, the hard framework comprises a cylindrical base, a handle part extending from one end of the base to both sides, the base is provided with a barrel groove for inserting a barrel of an injection syringe, the handle part is provided with a flange groove for inserting a flange of the barrel of the injection syringe and a plunger groove for passing a plunger rod, and the barrel groove, the flange groove and the plunger groove are communicated together; an upper surface of the handle part is provided with a positioning column protruding upward, and the handle part is provided with a channel for communicating the upper surface and a lower surface; the upper surface and the lower surface of the handle part are respectively provided with an upper surface soft gel and a lower surface soft gel, and the upper surface soft gel and the lower surface soft gel are integrated by a channel soft gel located in the channel. When the gel is injected, the end surface of the positioning column can be pressed by a template, so that the handle part can withstand the impact of the gel injection and will not be deformed. At the same time, as long as the liquid soft gel is injected below the handle part, the soft gel can flow through the soft gel channel and cover the upper surface of the handle part. After solidification and molding, the upper and lower surface soft gels are integrated, the hard framework is combined more closely, and the soft gels are not easy to fall off, so that the service life is long. At the same time, when the plunger rod is pulled, the fingers contact the soft gel body of the device, the use is more comfortable, and the demand for long-term use is met.

[0007] Preferably, the channel is a through hole penetrating the upper and lower surfaces of the handle part. The through hole structure can make the soft gel pass through the center of the handle part, and the soft gel and the hard framework are interlaced and combined more closely.

[0008] Preferably, the channel is a through groove opened on the side surface of the handle part and communicating the upper and lower surfaces of the handle part. The upper and lower surface soft gels can also be integrated, and the device has aesthetic appearance.

[0009] Preferably, the plunger groove is provided with a surrounding fence surrounding the plunger rod, the surrounding fence is integrally formed on the upper surface of the handle part, and the height of the surrounding fence matches the height of the positioning column. The surrounding fence structure can ensure that the upper surface soft gel will not be worn due to the collision of the plunger rod, and the height of the upper surface soft gel is limited together with the positioning column, so that the thickness of the upper surface soft gel is more uniform. At the same time, the device has aesthetic appearance.

[0010] Preferably, the outer surface of the base is wrapped with a base soft gel, and the base soft gel is integrated with the lower surface soft gel. In this way, the range of the soft gel contacted by the fingers is increased, and the area of the soft gel wrapped around the hard framework is also increased, so that the hard framework and the soft gel are combined more closely.

[0011] Preferably, the base is provided with a stop ring at the end away from the handle part, the outer surface of the stop ring is also wrapped with a stop ring soft gel, and the stop ring soft gel is integrated with the base soft gel. In this way, the range of the soft gel contacted by the fingers is increased, and the area of the soft gel wrapped around the hard framework is also increased, so that the hard framework and the soft gel are combined more closely. At the same time, the stop ring can also be used as a force point of the fingers to move the plunger rod away from the barrel of the injection syringe, so that the operation of pulling the plunger rod can be completed by one hand.

[0012] Preferably, the lower surface of the handle is provided with two soft rubber flaps symmetrically distributed about the barrel groove, which are integrated with the soft rubber of the retaining ring, the base and the lower surface. In this way, the range of soft rubber contacted by the fingers is increased, and the area of the soft rubber wrapping the hard skeleton is also increased, so that the combination of the two is more compact. At the same time, the hard skeleton at the barrel groove can be prevented from scratching the hand.

[0013] Preferably, the lower surface of the handle is provided with an embedded groove, and the embedded groove is provided with embedded soft rubber, which is integrated with the soft rubber of the lower surface. In this way, the range of soft rubber contacted by the fingers is increased, and the area of the soft rubber wrapping the hard skeleton is also increased, so that the combination of the two is more compact. At the same time, it is more aesthetic.

[0014] Preferably, the positioning columns and the soft rubber channels are symmetrically distributed on both sides of the handle. The positioning columns and the soft rubber channels are distributed at the most deformable position of the handle, which not only increases the overall strength, but also has more aesthetic appearance.

[0015] The application also provides a manufacturing method of the syringe composite boosting device, which comprises the following steps:

[0016] Step 1: complete the injection molding of the hard skeleton;

[0017] Step 2: use a template to press against the upper end surface of the positioning column, and inject liquid soft rubber from below the handle, so that it is distributed on the lower surface of the handle, the outer surface of the base, and flows through the channels to be distributed on the upper surface of the handle;

[0018] Step 3: after the liquid soft rubber is solidified, the soft rubber body is formed, and the manufacturing is completed.

[0019] The manufacturing method of the application can effectively prevent the deformation of the handle, and only one injection of glue can fill the upper and lower surfaces of the handle with soft rubber, greatly improving the processing efficiency, greatly improving the comfort of use, and improving the overall bonding strength and service life.

[0020] The syringe composite boosting device and the manufacturing method thereof provided by the application have at least the following advantages:

[0021] 1.

[0022] 2. The application only needs one injection of glue to fill the upper and lower surfaces of the handle with soft rubber, and the handle will not deform due to the impact of the glue injection.

[0023] 3. The outer surface of the application is clear in levels and has more aesthetic appearance, which greatly reduces the nervousness during the operation and is conducive to promotion. Attached Figure Description

Detailed Implementation

[0034] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0035] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0036] Example 1: As Figures 1-6 As shown, this syringe composite propulsion device consists of a rigid frame 1 and a soft rubber body 2. The rigid frame 1 is made of hard plastic materials such as ABS, and the soft rubber body 2 is made of elastic soft rubber materials such as TPE. The rigid frame 1 is injection molded entirely from ABS material, and its frame forms a cylindrical base 11 with a notch to form a groove 3 for inserting the syringe barrel 7. The handle 12 also has a notch to form a flange groove 4 for inserting the syringe barrel flange 71 and a plunger groove 5 for passing the plunger rod 6. The groove 3, flange groove 4, and plunger groove 5 are connected together so that the syringe can pass through these three grooves, as shown. Figure 6 As shown, the main body of the handle 12 extends from the upper end of the flange groove 4 frame to both sides. This main body has a certain curvature, which conforms to ergonomics. This curvature can bend downwards or upwards as shown in the figure, which will not be elaborated further here.

[0037] The upper surface of the handle 12 is injection molded with positioning columns 13 on both sides, and the upper end surface of the positioning columns 13 is almost parallel to the upper surface of the handle, which is more convenient for positioning. The handle 12 is provided with cylindrical channels 14 on both sides, which are connected with the upper and lower surfaces. The upper and lower surfaces of the handle 12 are respectively provided with upper surface soft glue 21 and lower surface soft glue 22, and the upper surface soft glue 21 and the lower surface soft glue 22 are connected by channel soft glue 24 located in the channel 14. In this embodiment, the channel soft glue 24 is located inside and cannot be seen from the outside. Therefore, the outer surface of the device forms a three-layer structure of the upper surface soft glue 21, the hard skeleton 12 and the lower surface soft glue 22, which is more beautiful in appearance and is conducive to reducing the nervousness during the operation. This embodiment is a three-layer structure, and of course it can also be made into a five-layer structure, a seven-layer structure and the like. The plunger groove 5 is provided with a fence 15 surrounding the plunger rod 6, which is integrally formed on the upper surface of the handle 12, and the height thereof is matched with the height of the positioning column 13, and the height thereof is substantially the same, so that the thickness of the upper surface soft glue 21 can be processed uniformly. The upper end surface of the fence 15 is also substantially parallel to the upper surface of the handle.

[0038] The outer surface of the base 11 is wrapped with base soft glue 23. The end of the base 11 away from the handle 12 is provided with a stop ring 17, and the outer surface of the stop ring 17 is also wrapped with stop ring soft glue 25. The lower surface of the handle 12 and the stop ring 17 are provided with two pieces of baffle soft glue 26 which are symmetrically distributed with the cylinder groove 3 as the center. The lower surface of the handle 12 is provided with an embedding groove 16, and the embedding groove 16 is provided with embedding soft glue 27.

[0039] As shown in Figure 2 , the embedding soft glue 27, the baffle soft glue 26, the stop ring soft glue 25, the base soft glue 23, the upper surface soft glue 21 and the lower surface soft glue 22 are connected to form a soft glue body 2, so that the structure of the soft glue body 2 is more wrapped and combined with the hard skeleton 1. The two form a state of you in me and me in you, and are not easy to fall off.

[0040] As shown in Figure 7 , Figure 8 , the difference between the embodiment 1 is that the channel 14 is a through groove which is opened on the side surface of the handle 12 and is connected with the upper and lower surfaces of the handle. Of course, the through groove can be opened at any position on the side surface of the handle 12, which does not affect the use effect.

[0041] The application provides a manufacturing method of the above-mentioned syringe composite boosting device, which comprises the following steps:

[0042] Step 1: injection molding of the hard skeleton 1 is completed;

[0043] Step 2: Use a template to hold the upper end face of the positioning post 13, and inject liquid soft glue from below the handle 12, so that it is distributed on the lower surface of the handle 12, the base 11 and the outer surface of the retaining ring 17, and flows through the channel 14 to be distributed on the upper surface of the handle 12; and is distributed between the lower surface of the handle 12 and the retaining ring 17 to form the baffle soft glue 26.

[0044] Step 3: Wait for the liquid soft glue to solidify and form soft glue 2, then the production is complete.

[0045] The manufacturing method of the present invention can ensure that the handle 12 will not be deformed due to impact, and the entire soft rubber body 2 can be manufactured in one injection, covering the upper and lower surfaces of the handle 12, which greatly improves the comfort during use.

[0046] The method of using the syringe compound booster device of the present invention is as follows:

[0047] First, such as Figure 6 As shown, the device of the present invention is installed on a syringe, with the syringe barrel 7 located in the barrel groove 3, the syringe barrel flange 71 located in the flange groove 4, and the plunger rod 6 located in the plunger groove 5.

[0048] 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 12, respectively located on both sides of the base 11. By applying force with the fingers, the plunger rod 6 can be pushed.

[0049] 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 12 or the upper surface of the retaining ring 17. By applying force with the fingers, the plunger rod 6 can be pulled back.

[0050] In the above usage methods, the fingers come into contact with the device of the present invention 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 promotion.

[0051] When the syringe needs to be replaced, the device of this invention can be easily removed from the syringe and inserted into another syringe. The rigid frame 1 ensures that it will not deform after multiple insertions and removals, thus meeting the needs of long-term use. In addition, the soft rubber body 2 ensures that it will not hurt hands during insertion and removal, resulting in good performance.
