[0037] As Figures 1 to 6 shown, the needle assisting system according to the embodiment of the present invention mainly includes a bottom plate 10, a needle assisting component 20 and a subcutaneous implantable pipeline 30.

[0038] The base plate 10 has a base plate through hole 101 and a base plate buckle 102. The base plate 10 is used to contact the user's skin and to at least partially fix the subcutaneous implantation tube 30.

[0039] The needle assisting assembly 20 mainly includes a housing 201, a button 202, a puncture needle holder 203, a puncture needle 204, and a spring 205.

[0040] The bottom of the housing 201 is connected to the base plate 10 through a detachable fixing device. The detachable fixing device can be a clip mechanism 201a, which has the advantages of multi-directional force application, firm combination, and easy processing. The interior of the housing 201 has a needle assisting channel 201b perpendicular to the base plate 10 and with an opening aligned with the base plate through hole 101. The housing 201 includes a housing deformable part 201c, which deforms when a force greater than the pressing force threshold is applied and allows the button 202 to slide in the needle assisting channel 201b. The needle assisting channel 201b also includes a channel side hole 201d.

[0041] The skin-remote end of the button 202 is located outside the top surface of the housing 201, and the skin-proximal end is located within the needle assisting channel 201b. To facilitate the user to press the button 202 with a finger or palm, the top of the button 202 has a pressing platform 202a.

[0042] The button 202 also includes a button deformable part 202b. Before the needle assisting operation, the button deformable part 202b cooperates with the part above the channel side hole 201d of the needle assisting channel 201b so that the button deformable part 202b deforms and engages with the top of the puncture needle holder 203. After the needle assisting operation, the button deformable part 202b partially embeds into the channel side hole 201d so that the button deformable part 202b returns to its original state and disengages from the top of the puncture needle holder 203. The number of the button deformable parts 202b can be four, and they are evenly arranged on the contour circle of the circular cross-section of the button 202.

[0043] The button 202 also includes a release control part. Before being triggered, the release control part can prevent the bottom of the housing 201 from separating from the base plate 10 before the needle assisting operation, and after being triggered, it can assist the bottom of the housing 201 to separate from the base plate 10 after the needle assisting operation. The release control part can specifically be a side wing 202c, which is arranged on the movement track of the clip mechanism 201a of the housing 201. At the same time, the housing 201 also includes a housing outer hole 201e that matches the shape of the side wing 202c. When the side wing partially embeds into the housing outer hole 201e, the bottom of the housing 201 can be separated from the base plate 10.

[0044] The button 202 further includes a buckle 202d, which is located above the deformable member 201c of the housing. The number of buckles 202d can be two, which are oppositely arranged on the contour of the circular cross-section of the button 202 and are staggered from the position of the deformable member 202b of the button.

[0045] The needle assisting system is triggered by the user pressing the button 202, and the implantation of part of the subcutaneous implantation tube is completed by utilizing inertia force. Specifically, when the user presses the button 202, if the pressing force does not exceed the pressing force threshold, the needle assisting system will not start; when the pressing force threshold is exceeded, the deformable member 201c of the housing will deform and open to both sides, allowing the buckle 202d of the button 202 to pass through the needle assisting channel 201b, and then the needle assisting system will start. This pressing force threshold can be adjusted according to the actual situation, and the recommended value is 15 to 30 N. Because the triggering force is large and the triggering is sudden, the user will press the button 202 all the way to the position closest to the skin under the action of inertia (see the subsequent analysis for details).

[0046] The puncture needle holder 203 is located in the needle assisting channel 201b and below the button 202.

[0047] The puncture needle 204 is dimensionally matched with the subcutaneous implantation tube 30. Before the needle assisting operation, the bottom of the puncture needle holder 203 is fixedly connected to the tail end of the puncture needle 204, and the subcutaneous implantation tube 30 is sleeved on the middle section of the puncture needle 204. During the needle assisting operation, the puncture needle 204, the subcutaneous implantation tube 30 and the puncture needle holder 203 move together. After the needle assisting operation, the puncture needle 204 is separated from the subcutaneous implantation tube 30, and the puncture needle 204 is only fixed by the puncture needle holder 203.

[0048] The subcutaneous implantation tube 30 can generally be selected from a 4.5 mm hard needle, a 6 mm soft needle or a 9 mm soft needle.

[0049] The skin-remote end of the spring 205 abuts against the bottom of the puncture needle holder 203, and the skin-proximal end abuts against the bottom of the housing 201. The spring 205 is in a relaxed state before the needle assisting operation; in a compressed state during the needle assisting operation; and in a rebounding state after the needle assisting operation.

[0050] The skin-proximal end of the subcutaneous implantation tube 30 has a part suitable for at least partially inserting into the subcutaneous tissue of the user. The subcutaneous implantation tube 30 has a clamping member 301 that matches the bottom plate buckle 102. The subcutaneous implantation tube 30 abuts against the bottom of the puncture needle holder 203 before the needle assisting operation, and is clamped to the bottom plate buckle 102 of the bottom plate 10 by the clamping member 301 after the needle assisting operation. A sealed and waterproof design is preferably adopted between the subcutaneous implantation tube 30 and the bottom plate 10, which can be specifically realized by an O-ring 302 or an interference fit.

[0051] Preferably, the needle assisting system may further include at least one safety locking device 40. The safety locking device may be disposed between the housing 201 and the button 202. The safety locking device 40 may be removed from or damaged to leave the needle assisting system. Before the safety locking device 40 leaves the main body part of the needle assisting system, the main body part of the needle assisting system cannot be activated.

[0052] The assembling method of the needle assisting system according to the embodiment of the present invention mainly includes the following steps.

[0053] (1) Bond and fix the tail end of the puncture needle 204 to the bottom of the puncture needle seat 203, and then penetrate the tip of the puncture needle 204 through the subcutaneous implantation tube 30 so that the subcutaneous implantation tube 30 is fixed below the puncture needle seat 203;

[0054] (2) Detachably connect the bottom of the housing 201 to the bottom plate 10, and then place the spring 205 into the needle assisting channel 201b of the housing 201;

[0055] (3) Place the fixedly attached puncture needle seat 203, puncture needle 204, and subcutaneous implantation tube 30 together into the needle assisting channel 201b of the housing 201;

[0056] (4) Leave the skin - far end of the button 202 above the top surface of the housing 201, place the skin - near end of the button 202 into the needle assisting channel 201b of the housing 201, and mate the deformable button member 202b with the part above the channel side hole 201d of the needle assisting channel 201b so that the deformable button member 202b deforms and engages with the top of the puncture needle seat 203, and align the buckle 202d with the position of the deformable housing member 201c, that is, make the buckle 202d be in the skin - far direction (i.e., the upper side in the figure) of the deformable housing member 201c.

[0057] If the needle assisting system further includes a safety locking device, the assembling method should further include the step: setting the safety locking device 40 between the housing 201 and the button 202.

[0058] After completing the above - mentioned assembling process, the needle assisting system can be packaged and sterilized.

[0059] The using method of the needle assisting system according to the embodiment of the present invention is introduced in detail as follows:

[0060] The user takes out the needle-assisting system from the package, removes the safety locking device 40 (if any), and then presses the button 202 with force. When the pressing force is small, the buckle 202d in the button 202 is blocked by the deformable member 201c of the housing, and the needle-assisting system cannot be activated. When the pressing force breaks through the pressing force threshold, the deformable member 201c of the housing deforms to both sides, causing the button 202 to be pressed and, under the action of inertia, pushing the puncture needle seat 203, the puncture needle 204, and the subcutaneous implantation tube 30 to slide together in the needle-assisting channel 201b while compressing the spring 205.

[0061] During the period when the button 202 just starts to slide downward, as Figure 7 (for the convenience of observing other details, Figure 7 the spring in Figure 8 is omitted from the drawing) and as shown in

[0062] When the button 202 continues to move to the first specific position, as shown in Figures 9 to 11 , the subcutaneous implantation tube 30 is clamped and fixed to the bottom plate buckle 102, and the implantation is completed. At the same time, the deformable member 202b of the button is partially embedded in the side hole 201d of the channel, causing the deformable member 202b of the button to return to its original state and disengage from the top of the puncture needle seat 203. The puncture needle seat 203, together with the puncture needle 204, moves away from the skin under the elastic force of the spring 205, that is, the needle withdrawal is triggered.

[0063] When the button 202 continues to move to the second specific position, as shown in Figures 12 to 14 , the release structure is triggered, that is, the wing 202c is embedded in the outer hole 201e of the housing, causing the clip mechanism 201a of the housing to pop out outward, so that the bottom of the housing 201 can be separated from the bottom plate 10. This step is the disassembly and detachment.

[0064] The needle-assisting assembly 20 is removed in a direction perpendicular to the bottom plate 10. At this time, only the bottom plate 10 and the subcutaneous implantation tube 30 remain on the user's skin (as shown in Figure 15 ). The needle-assisting assembly 20 composed of the housing 201, the button 202, the puncture needle seat 203, the puncture needle 204, and the spring 205 (as shown in Figure 16 ) can be discarded into a specific medical sharps waste bin.

[0065] As can be seen from the above, the needle-assisting system of the embodiment of the present invention has many advantages:

[0066] First aspect: When the subcutaneous implantation tube is implanted in place, the spring is triggered to retract, realizing the automatic needle withdrawal function, which is convenient to operate and saves time.

[0067] Second aspect: When the subcutaneous implantation tube is implanted in place and the spring rebounds to withdraw the needle, the button will continue to be pressed down under the action of inertia, and the flanks of the button will force the housing clip to open to both sides, realizing the disassembly and detachment of the needle assisting system from the base plate. This method combines the needle assisting implantation action and the disassembly action into one, with simple operation and no misoperation due to reversed order.

[0068] Third aspect: Initially, the spring is in a free state (or a slightly compressed state), and the spring is compressed simultaneously during the implantation process of the subcutaneous implantation tube; after the subcutaneous implantation tube is successfully implanted in place, the spring is compressed to the working position and triggered to rebound. Its advantages include: 1. It is easier to assemble the system without the need to compress the spring; 2. It reduces the risk of the spring popping open by itself before the system is used, making the system more stable and safer; 3. There is no need to compress the spring in advance, which means avoiding the spring being in a compressed and stressed state for a long time, thus reducing the risk of permanent deformation or fracture and increasing the standby life of the system.

[0069] Fourth aspect: The structure is simple, and the manufacturing cost and usage cost are relatively low.

[0070] The assembly method and usage method of the needle assisting system of the present invention have the advantages of simple operation.

[0071] The above specific embodiments do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
