Description

Technical Field

[0001] The utility model relates to the technical field of detection tooling, in particular to a tooling for detecting the needle tube length of an hyaluronic acid needle. Background Art

[0002] The exposed length of the needle tube of an hyaluronic acid needle is a very important indicator, because when the exposed length is too long, it is easy to damage the nerves. The existing method of detecting the needle tube length of an hyaluronic acid needle mostly uses a projector for measurement. However, the measurement process requires clamping, focusing, marking and other steps, so it takes about ten minutes to measure a hyaluronic acid needle. Therefore, it is difficult to achieve a full inspection and there is a certain risk of use. Summary of the invention

[0003] In order to solve the above problems, the main purpose of the utility model is to provide a needle tube length detection tool that can quickly detect whether the needle tube length of the hyaluronic acid needle meets the standard.

[0004] In order to achieve the main purpose of the utility model, the utility model provides a needle tube length detection tool for an hyaluronic acid needle, which includes a holder and a diaphragm. The holder is provided with a plug hole, which penetrates the holder in the height direction of the holder. The diaphragm is installed on the holder. The diaphragm can be elastically deformed. The diaphragm divides the plug hole into two parts or the diaphragm covers one end of the plug hole.

[0005] As can be seen from the above, when testing the needle tube length of the hyaluronic acid needle, the hyaluronic acid needle is inserted into the socket. When the needle tube length of the hyaluronic acid needle is too long, the excessively long needle tube will push up the diaphragm to form a conical bulge at the corresponding position of the diaphragm. By designing the needle tube length detection tooling, the inspector can quickly and intuitively observe the bulge on the diaphragm, thereby realizing rapid detection of the needle tube length of the hyaluronic acid needle. Moreover, the needle tube length detection tooling can also be used to detect the entire batch of hyaluronic acid needles.

[0006] A preferred solution is that the card seat includes a seat body and a cover body, the cover body and the seat body are distributed along the height direction, the cover body and the seat body are detachably connected, the jack is formed on the seat body and the cover body, and the diaphragm is installed between the seat body and the cover body and separates the jack.

[0007] As can be seen from the above, this design makes the diaphragm replaceable, so that the service life of the needle tube length detection tooling can be extended by replacing the diaphragm.

[0008] A further solution is that one of the seat body and the cover body is formed with a recess in the circumferential direction of the insertion hole, and the other is formed with a protrusion in the circumferential direction of the insertion hole; the diaphragm is arranged at the bottom of the recess, and the protrusion is inserted into the recess and abuts against the diaphragm.

[0009] As can be seen from the above, this design is conducive to limiting the diaphragm and reducing the volume of the needle tube length detection tooling.

[0010] A further solution is that a first fixing frame is provided on the circumference of the diaphragm, the first fixing frame is located on the circumference of the insertion hole, and the first fixing frame is adjacent to the bottom of the recess and the protrusion respectively.

[0011] As can be seen from the above, by providing a first fixed frame on the circumference of the diaphragm, the diaphragm can always remain taut, thereby ensuring the reliability and accuracy of the needle tube length detection tooling in detecting the needle tip of the hyaluronic acid needle, and also allowing the operator to observe the test results more clearly.

[0012] A further solution is that a first connecting hole is provided on the base body, a first through hole is provided on the cover body, the first through hole penetrates the cover body in the height direction, and the needle tube length detection tooling also includes a first fastener, which is connected to the first connecting hole after passing through the first through hole; or a first magnet is provided on the base body, and a second magnet is provided on the cover body, and a magnetic force of attraction is formed between the first magnet and the second magnet; or the base body has a first snap-fit ​​structure, and the cover body has a second snap-fit ​​structure, and the first snap-fit ​​structure and the second snap-fit ​​structure are snap-fitted and connected.

[0013] As can be seen from the above, the above design makes the assembly and disassembly between the base body and the cover body simpler and easier to operate.

[0014] Another preferred solution is that the diaphragm is bonded and fixed to the card holder, and the diaphragm covers one end of the insertion hole.

[0015] As can be seen from the above, this design is conducive to simplifying the structure of the needle tube length detection tooling, reducing the production cost of the needle tube length detection tooling, and when the diaphragm is damaged, the diaphragm can be torn off from the holder and then a new diaphragm can be re-bonded and fixed.

[0016] Another preferred solution is that a second fixing frame is provided on the circumference of the diaphragm, the second fixing frame is detachably connected to the holder, and the diaphragm covers one end of the insertion hole.

[0017] As can be seen from the above, the design is conducive to simplifying the structure of the needle tube length detection tooling and reducing the production cost of the needle tube length detection tooling.

[0018] A further solution is that a second connecting hole is provided on the holder, a second through hole is provided on the second fixed frame, the second through hole penetrates the second fixed frame in the height direction, the needle tube length detection tooling also includes a second fastener, the second fastener is connected to the second connecting hole after passing through the second through hole; or a third magnet is provided on the holder, a fourth magnet is provided on the second fixed frame, and a magnetic force of attraction is formed between the third magnet and the fourth magnet, or the second fixed frame is made of iron, and a magnetic force of attraction is formed between the third magnet and the second fixed frame; or the holder has a third snap-fit ​​structure, the second fixed frame has a fourth snap-fit ​​structure, and the third snap-fit ​​structure and the fourth snap-fit ​​structure are snap-fitted and connected.

[0019] As can be seen from the above, this design makes the replacement of the diaphragm more convenient.

[0020] A further solution is that the socket has a first hole segment and a second hole segment, and in the height direction, the projection of the first hole segment is located within the projection of the second hole segment; the diaphragm separates the first hole segment, or the diaphragm covers one end of the first hole segment away from the second hole segment.

[0021] It can be seen from the above that the structural design of the jack can ensure the stability during the detection process and the detection effect of the needle tube length detection tooling.

[0022] A further solution is that the diaphragm is a PP film, a PA film or a rubber mold.

[0023] It can be seen from the above that the design of the diaphragm is conducive to ensuring the service life of the diaphragm and the reliability of the needle tube length detection tooling detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The first embodiment of the needle tube length detection tool

[0036] Reference Figure 1 The needle tube length detection tool 100 is used to detect the length of the needle tube 101 of the water light needle needle 10; Figures 2 to 4 The needle tube length detection tool 100 includes a card base 1 and a diaphragm 2. The card base 1 is provided with a plug hole 11, and the plug hole 11 penetrates the card base 1 in the height direction of the card base 1. The diaphragm 2 is installed on the card base 1, and the diaphragm 2 can be elastically deformed. Among them, the diaphragm 2 is preferably a PP (polypropylene) film. Of course, as other optional solutions, the diaphragm 2 can also be a PA (polyamide) film or a rubber mold; this design is conducive to ensuring the service life of the diaphragm 2 and the reliability of the needle tube length detection tool 100.

[0037] In this embodiment, the card base 1 is a split structure, and the diaphragm 2 divides the insertion hole 11 into two parts. Specifically, the card base 1 includes a base 12 and a cover 13, and the cover 13 and the base 12 are distributed along the height direction of the card base 1, and the cover 13 and the base 12 are detachably connected; in addition, the insertion hole 11 is formed on the cover 13 and the base 12, and the diaphragm 2 is installed between the base 12 and the cover 13, and divides the insertion hole 11. This design makes the diaphragm 2 replaceable, so that the service life of the needle tube length detection tool 100 can be extended by replacing the diaphragm 2.

[0038] Preferably, one of the seat 12 and the cover 13 is formed with a recess 131 on the circumference of the insertion hole 11, and the other is formed with a protrusion 121 on the circumference of the insertion hole 11, and the protrusion 121 is arranged to match the recess 131. The diaphragm 2 is arranged at the bottom of the recess 131. When the seat 12 and the cover 13 are assembled, the protrusion 121 is inserted into the recess 131 and abuts against the diaphragm 2, thereby clamping and fixing the diaphragm 2 and keeping the diaphragm 2 in a tight state to ensure the detection accuracy of the needle tube length detection tool 100; this design is conducive to limiting the position of the diaphragm 2 and also conducive to reducing the volume of the needle tube length detection tool 100. As in the present embodiment, the recess 131 is formed on the cover 13, and the protrusion 121 is formed on the seat 12.

[0039] like Figure 5 As shown, preferably, a first fixing frame 21 can be arranged on the circumference of the diaphragm 2, and the first fixing frame 21 is located in the axial direction of the insertion hole 11; when the diaphragm 2 is installed between the seat body 12 and the cover body 13, the fixing frame is adjacent to the bottom of the recess 131 and the protrusion 121 respectively. The arrangement of the first fixing frame 21 enables the diaphragm 2 to always remain in a tight state, so as to ensure the reliability and defect prevention of the needle tube length detection tool 100 on the hyaluronic acid needle 10, and also enables the operator to observe the detection result more clearly.

[0040] In addition, in this embodiment, the insertion hole 11 is configured as a stepped hole; specifically, the insertion hole 11 has a first hole section 111 and a second hole section 112, and the first hole section 111 and the second hole section 112 are preferably coaxially arranged. Of course, the first hole section 111 and the second hole section 112 can also be changed according to the specific structure of the water light needle needle 10, such as making the first hole section 111 and the second hole section 112 non-coaxially offset. In the height direction, the projection of the first hole section 111 is located within the projection of the second hole section 112, and the first hole section 111 is formed on the seat body 12 and the cover body 13 respectively, so that the diaphragm 2 separates the first hole section 111, and the second hole section 112 is formed on the seat body 12. Through the structural design of the jack 11, when the needle tube length detection tool 100 detects the length of the needle tube 101 of the hyaluronic acid needle 10, the housing 102 of the hyaluronic acid needle 10 can be inserted into the second hole section 112 until it is adjacent to the bottom of the second hole section 112, so as to position the hyaluronic acid needle 10, thereby ensuring stability during the detection process and ensuring the detection effect of the needle tube length detection tool 100. Furthermore, by designing the depth of the second hole section 112 (i.e., the spacing between the second hole section 112 and the diaphragm 2), the second hole section 112 can be used as the insertion depth reference of the hyaluronic acid needle 10, and then by designing the depth of the second hole section 112, the needle tube length detection tool 100 can be used to detect whether the length of the needle tube 101 of the hyaluronic acid needle 10 is too long or too short.

[0041] In addition, in this embodiment, the seat body 12 is provided with a first connection hole 122, which is parallel to the height direction of the card seat 1; the cover body 13 is provided with a first through hole 132, which penetrates the cover body 13 in the height direction; the needle tube length detection tool 100 also includes a first fastener 3, which passes through the first through hole 132 and is connected to the first connection hole 122. Preferably, the first connection hole 122 is a light hole or a threaded hole, and the first fastener 3 is a bolt; further, a knurled nut is provided in the first connection hole 122, and the knurled nut is used to connect with the bolt to protect the seat body 12, thereby extending the service life of the seat body 12.

[0042] When it is necessary to detect whether the length of the needle tube 101 of the hyaluronic acid needle 10 is too long, insert the hyaluronic acid needle 10 into the socket 11 of the cartridge 1 until the shell 102 of the hyaluronic acid needle 10 is adjacent to the bottom of the second hole section 112 of the socket 11; when the length of the needle tube 101 of the hyaluronic acid needle 10 is too long, the excessively long needle tube 101 will push up the diaphragm 2 to form a conical bulge at the corresponding position of the diaphragm 2.

[0043] It can be seen that through the design of the needle tube length detection tool 100, the detection personnel can quickly and intuitively observe the bulge on the diaphragm 2, and then realize the rapid detection of the length of the needle tube 101 of the hyaluronic acid needle 10 (generally, the detection of the length of the needle tube 101 of the hyaluronic acid needle 10 can be completed within 10 seconds), and the use of the needle tube length detection tool 100 can also realize the detection of the entire batch of hyaluronic acid needles 10.

[0044] When it is necessary to detect whether the length of the needle tube 101 of the hyaluronic needle needle 10 is too short, the distance between the second hole section 112 and the diaphragm 2 can be adjusted to meet the requirement for detecting whether the length of the needle tube 101 of the hyaluronic needle needle 10 is too short; during the detection, when the hyaluronic needle needle 10 is inserted into the insertion hole 11 until it is adjacent to the bottom of the second hole section 112, if the length of the needle tube 101 of the hyaluronic needle needle 10 meets the requirement, the needle tube 101 of the hyaluronic needle needle 10 will form nine conical convex hulls on the diaphragm 2, and when the length of the needle tube 101 of the hyaluronic needle needle 10 is too short, the conical convex hulls at the corresponding position on the diaphragm 2 will become shorter or disappear.

[0045] Second embodiment of the needle tube length detection tool

[0046] Reference Figure 6 The difference between this embodiment and the first embodiment of the needle tube length detection tool lies in the connection method between the seat body and the cover body of the holder. Specifically, in this embodiment:

This design makes the disassembly and assembly between the base body 41 and the cover body 42 simpler, more convenient and easier to operate.

This design is conducive to simplifying the structure of the needle tube length detection tooling, reducing the production cost of the needle tube length detection tooling, and when the diaphragm 52 is damaged, the diaphragm 52 can be torn off from the holder 51 and then a new diaphragm 52 can be bonded and fixed again.
