Description

Technical Field

[0001] The utility model belongs to the manufacturing field of continuous monitoring sensors, in particular to a tooling fixture for semi-implanted sensors. Background Art

[0002] A continuous monitoring device for human body fluid detection usually includes a needle aid, a transmitter and a sensor implanted in the human body. The sensor includes a wire electrode at the implant end and a conductive sheet that cooperates with the transmitter. Semi-implanted sensors are small in size and difficult to manufacture. They are generally made of flexible circuits, which are easily damaged. In addition, there are multiple electrode contacts on the conductive sheet circuit, which is difficult to fix.

[0003] In the prior art, during production, a lower plate and an upper pressure plate are generally used to clamp one or a row of semi-implanted sensors through multiple clamps, and the sensors are clamped from multiple different directions, resulting in low production or testing efficiency. Since the enzymes, cross-linking agents and other substances used in the sensor manufacturing process are expensive, a multimeter is generally used to perform short-circuit detection on each sensor after the sensor electrode is printed. If the sensor is short-circuited, the sensor is discarded and does not undergo subsequent clamping and manufacturing process flow. If the sensor is not short-circuited, the sensor is clamped in a tool and then subjected to dipping, cross-linking, cleaning and other manufacturing process flows. However, the test efficiency of using a multimeter to detect sensor short circuits is low.

[0004] In summary, how to solve the problems of low efficiency in sensor production and short-circuit testing, easy damage of sensors, difficulty in fixing, and cumbersome production are issues that technical personnel need to solve at present. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

The spaced-apart snap-fitting columns 13 and snap-fitting grooves 17 make the side wall of the positioning groove 11 near the sensor implantation section 61 discontinuous. The pressing plate 2 forms spaced-apart grooves 21 and bosses 24 on the first surface near the substrate positioning groove 11. Bosses 24 are formed between the grooves 21. The positioning groove 11, the snap-fitting columns 13 and the snap-fitting grooves 17 are formed on the second surface away from the positioning groove 11 of the substrate 1. The bosses 24 can be adapted to the shape of the sensor (such as Figure 6 As shown), it can also be a rectangle or other shape that is greater than or equal to the area of ​​the sensor; when only one row of sensors is clamped, the pressure plate 2 does not need to place the sensor 6 on the other side away from the substrate 1, and the pressure plate 2 is flat on the other side away from the substrate 1; the fastener 3 passes through the through hole 12 formed when the pressure plate 2 and the substrate 1 are tightly fitted, so that the boss 24 is embedded in the snap-fit ​​groove 17 to firmly clamp the sensor 6, and the snap-fit ​​column 13 is embedded in the groove 21 to make way for the sensor implantation section 61, and the making way here means that multiple snap-fit ​​columns 13 are embedded in multiple grooves 21 and at least one side of the card and column 13 There is a certain gap between the groove 21 and the sensor implantation section 61, so that the sensor implantation section 61 extends out of the fixture. The extended sensor implantation section 61 is convenient for the operation of the production process such as dripping enzyme solution, cross-linking, cleaning, and coating the outer film, and does not affect the performance of the sensor conductive sheet 62, which solves the fixation problem in the production and manufacturing of wire electrodes with high softness, and realizes the clamping of the sensor conductive sheet 62 and the loosening of the sensor implantation section 61. The entire fixture is simple to combine and has a high degree of control. Multiple sensors can be clamped at the same time, and the processing efficiency is high.

The positioning groove 11 includes a bottom surface and two side walls that are substantially perpendicular to the bottom surface. The side wall close to the sensor implantation section 61 is composed of spaced-apart snap-fit ​​columns 13 and snap-fit ​​grooves 17. The snap-fit ​​grooves 17 between the snap-fit ​​columns 13 are used to accommodate the embedding of the bosses 24 of the pressure plate 2. The grooves 21 between the bosses 24 are used to accommodate the embedding of the snap-fit ​​columns 13. After the grooves 21 and the columns 13 are matched, a certain gap is left for the sensor implantation section 61 to extend out of the fixture. The substrate 1 and When the pressure plate 2 is tightly fitted or the pressure plates 2 are tightly fitted to each other, the locking column 13 will be embedded in the groove 21 and make way for part of the sensor implantation section 61.

Specifically, the auxiliary boss 14 is extended along the side wall of the positioning groove 11 opposite to the engaging column 13 in the direction away from the sensor 6, and the auxiliary groove 22 is formed by being recessed along the side wall of the boss 24 opposite to the groove 21 in the direction away from the sensor 6. The recess refers to the recessing of the auxiliary groove 22 into the inside of the tooling fixture in a direction perpendicular to the placement position of the sensor. The height of the auxiliary boss 14 is less than or equal to the depth of the auxiliary groove 22. Preferably, the height of the auxiliary boss 14 is equal to the auxiliary groove.

The two sides refer to the long sides of the tooling fixture, and the two ends refer to the short sides of the tooling fixture; of course, the auxiliary boss 14 can be separately arranged on the surface where the positioning groove 11 or the boss 24 is located, without contacting the positioning groove 11 or the boss 24, and the auxiliary groove 22 can be separately arranged on the other side opposite to the auxiliary boss 14, without contacting the boss 24 or the positioning groove 11.

When the substrate 1 and the pressure plate 2 or the pressure plate 2 are aligned up and down, the auxiliary positioning piece 15 is embedded in the auxiliary positioning groove 23, indicating that the stacked fixture is installed in place, and the fixture is limited in the horizontal direction, and cannot be translated to both sides along the long side of the fixture and cannot be translated to both ends along the short side of the fixture; preferably, the height of the auxiliary boss 14, the depth of the auxiliary groove 22, the height of the auxiliary positioning piece 15, and the depth of the auxiliary positioning groove 23 are the same. When the fixture is assembled, the auxiliary boss 14 is embedded in the auxiliary groove 22, and the auxiliary positioning piece 15 is embedded in the auxiliary positioning groove 23, so that a through hole 12 is formed between the substrate 1 and the pressure plate 2, which is convenient for the insertion of the fastener 3.

[0038] like Figure 4 and Figure 5As shown, when the substrate 1 and the pressing plate 2 are tightly fitted, one or more through holes 12 can be formed for the fastener 3 to be inserted. The diameter of the through hole 12 remains unchanged, or the diameter of the through hole 12 in the substrate can be smaller than the diameter of the through hole 12 in the pressing plate, or the diameter of the through hole 12 can gradually decrease from the pressing plate to the substrate. The through holes 12 can be all provided with internal threads 16, or only the through holes 12 in the substrate 1 can be provided with internal threads 16, or the through holes 12 in the substrate 1 and part of the pressing plate 2 can be provided with internal threads 16; preferably, a through hole 12 is formed at each end of the substrate 1 and the pressing plate 2 and is located at a symmetrical position, the diameter of the through hole 12 can remain unchanged, the through hole 12 is provided with an internal thread 16 at least in the substrate 1, the top of the fastener 3 is a limiting platform 33, and the rest are bolts 31, and the two fasteners 3 pass through the pressing plate 2 and the substrate 1 when they are tightly fitted to form The through hole 12 is tightened by the external thread 32 of the bolt 31 and the internal thread 16 of the through hole 12, so that the limiting platform 33 is against the top of the tooling fixture to form a lock for the tooling fixture. If not all the pressing plates 2 are used, the external thread of the bolt 31 and the internal thread 16 of the through hole can also be tightened in cooperation, but the limiting platform 33 does not abut against the tooling fixture; when the diameter of the through hole 12 in the substrate 1 is smaller than the diameter of the through hole 12 in the pressing plate 2, there is an internal thread 16 in the substrate 1, the bottom of the fastener 3 is the bolt 31, the upper part is the cylinder 34, and the top is the limiting platform 33.

The diameter of the bolt 31 gradually decreases from the limit platform downward, and the fastener 3 passes through all the pressure plates 2 so that the limit platform 33 is against the fixture, and the external thread 32 of the bolt 31 is tightened with the internal thread 16 of the through hole 12 to form a lock for the fixture. If not all the pressure plates are used, the external thread of the bolt 31 can also be tightened with the internal thread 16 of the through hole, but the limit platform 33 does not contact the fixture.

The buffer layer 4 is adapted to be silicone according to the shape of the sensor conductive sheet 62. The silicone can be fixed to the bottom surface of the positioning groove 11 or the boss 24, or by arranging some positioning hooks on the bottom surface of the positioning groove 11 or the boss 24, and arranging positioning holes on the silicone. By inserting the positioning hooks into the positioning holes, the silicone is fixed. The silicone can protect the sensor during the clamping process and reduce the damage rate of the sensor. Specifically, When there are electrodes on both sides of the sensor conductive sheet 62, in order to reduce the damage rate of the sensor, a buffer layer 4 can be set on both the positioning groove 11 and the boss 24.

Of course, a buffer layer 4 can also be set on both the positioning groove 11 and the boss 24. The silicone used as the buffer layer can be set as conductive silicone at the position that contacts the sensor 6 electrode.

[0040] like Fig. 9As shown, the fixture also includes an indicating short-circuit component 5, which includes an indicator light 51, a power supply 52, a resistor 53 and a wire 54. The indicator light 51, the power supply 52, the resistor 53 and the wire 54 are fixed in series to the inside of the substrate 1 and / or the pressure plate 2. The power supply 52 is located inside the substrate or the pressure plate, and the indicator light 51 is partially located inside the substrate or the pressure plate, and partially leaks out of the substrate or the pressure plate, so as to facilitate the identification of the indication of the short-circuit component on the sensor short circuit. According to the setting requirements, the indicator light 51 and the power supply 52 can be placed inside the same substrate or pressure plate, or the indicator light 51 and the power supply 52 can be placed inside the substrate and the pressure plate respectively; the detection principle of the indicating short-circuit component 5 is that when the indicator light 51, the power supply 52, the resistor 53, the wire 54 and the short-circuit sensor 6 form a loop, the indicator light is on, and an indicating short-circuit component 5 can be set at the corresponding position of each row of sensors to prompt that there is a short circuit in this row of sensors, or at each sensor A short-circuit indicating element 5 is provided at the corresponding position, and other existing technologies are used to cooperate to realize the detection of each sensor, and clearly indicate which specific sensor is short-circuited, or when a short-circuit is detected in a row, a multimeter is used to detect the specific sensor that is short-circuited; when the sensor 6 has electrodes printed on the front and back sides, the indicator light 51, the power supply 52, the resistor 53, the wire 54 and the conductive contacts 64 (the electrodes on the front and back sides) on the front and back sides of the short-circuit sensor 6 form a loop, and the indicator light 51 will light up. The short-circuit indicating element 5 can be provided at the corresponding position of each sensor to clearly indicate which specific sensor is short-circuited, or only one short-circuit indicating element 5 can be provided at the corresponding position of each row of sensors to prompt that the row of sensors has a short-circuit; when the sensor 6 has electrodes printed on one side, the indicator light 51, the power supply 52, the resistor 53, the wire 54 and the conductive contacts 64 on one side of the short-circuit sensor 6 form a loop, and the indicator light 51 will light up;Preferably, the electrodes of the sensor 6 are printed on both sides, and a conductive silicone rubber that matches the shape of the sensor conductive sheet 62 is fixed on the positioning groove 11 and the boss 24. An "L-shaped" channel extends outward from the slot hole of the auxiliary positioning groove 23, and one end of the "L-shaped" channel is located on the end face of the pressure plate 2, and the other end of the "L-shaped" channel is located on the boss 24. The channel on the end face of the pressure plate 2 is equipped with an indicator light 51, a resistor 53, and two wires 54, one of which A passes through the "L-shaped" channel roughly parallel to the long side direction of the fixture and is fixed to the bottom wall of the auxiliary positioning groove 23. The power supply 52 contacts the conductive end of the wire A and is fixed in the auxiliary positioning groove 23. The power supply is preferably Micro battery, of course, the power supply 52 may not be fixed in the fixture, and the indicating short-circuit member 5 may be powered by an external circuit or a dry cell or a storage battery. Another wire B is placed in the other end channel separated from the indicator light 51, and the conductive end of the wire B contacts the bottom wall of the groove of the boss 24. The contact here means that the wire can be fixed on the bottom wall by the existing technology and at least the conductive contact at its end is retained. The conductive contact of the wire A can contact the power supply 52, the conductive contact of the wire B contacts the conductive silicone / conductive contact / electrode, and the conductive silicone contacts the conductive sheet 62 of the sensor (when the substrate 1 and the pressure plate 2 are clamped, or when the pressure plates 2 are clamped), and the auxiliary positioning member 15 can The conductive coating is coated with a conductive coating, and the conductive coating is extended to the surface where the auxiliary boss 14 is located to the placement position of the sensor conductive sheet.

The conductive coating includes a metal conductive layer formed by various coating methods, a conductive tape or other special coating materials, such as a conductive paste used to fill the shielding gap. The electrical connection refers to the use of existing technology to manufacture a conductive path to achieve the electrical connection between the wire 54, the power supply 52, the resistor 53, the indicator light 51, the auxiliary positioning member 15 and the sensor 6 (when the substrate 1 and the pressure plate 2 are clamped, and the pressure plate 2 is clamped). The electrical connection can It is a way of transmitting electrons or current by wires, conductive coatings and other existing technologies; when the sensor 6 clamped by the pressure plate and the pressure plate card, or the substrate and the pressure plate card, is short-circuited, the indicator light 51, the resistor 53, the wire 54, the power supply 52, the auxiliary positioning member 15, the conductive silicone, and the sensor 6 will form a loop, and the indicator light will light up, indicating that this row of sensors is short-circuited. The addition of conductive silicone can not only assist the short-circuit indicator to form a loop, but also reduce the damage of the fixture to the sensor 6. Of course, the wire 54 and the resistor 53 can also be connected in series, and the indicator light 51 with a larger resistance value can be used. The wire can use the existing technology to make a conductive path instead of using the actual wire body. ;
