Description

Technical Field

[0001] This utility model relates to medical instruments, and more particularly to a medical monitoring device. Background Technology

[0002] Blood glucose meters implant an analyte sensor into the skin tissue to monitor blood glucose levels in real time. However, current mass production of analyte sensors suffers from significant variations in product consistency, and each sensor requires individual calibration and a unique calibration code. For example, the patent with notification number CN105581781B, which pertains to medical device inserts and methods for inserting and using medical devices, features a separate design for the needle applicator and needle retrieval box. Even with a one-to-one matching of the needle applicator and retrieval box, there is a chance of product mismatch due to factory management issues. Furthermore, addressing this potential problem increases the factory's classification and management costs. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a medical monitoring device.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0005] A medical monitoring device includes a needle assist device, a transmitter, and a needle retrieval box, wherein the transmitter is mounted on the needle assist device;

[0006] The needle collection box includes an upper mounting slot and a lower mounting slot. The needle aid with the transmitter is installed on the upper mounting slot, and the needle collection platform is installed in the lower mounting slot. The analyzer sensor is installed on the needle collection platform.

[0007] The port of the lower mounting slot of the needle collection box is sealed with a sealing cover, which seals the needle collection stage and the analyte sensor inside the lower mounting slot.

[0008] This medical monitoring device integrates both the needle assist device and the analyte sensor into the needle retrieval box. It combines the traditional needle assist device cover and the outer shell of the needle retrieval box into a single design, allowing for a strong correlation between the transmitter and the analyte sensor. This reduces the probability of misplaced shipments and lowers management costs during the warehousing phase.

[0009] Preferably, the bottom of the upper mounting slot is provided with a support column for supporting the transmitter. When the needle aid is installed on the needle collection box, the support column is positioned below the transmitter. The support column is used to support the transmitter and prevent it from falling off the needle aid during transportation.

[0010] Preferably, the needle assist device includes a needle assist housing, a trigger sleeve, and a pusher core. The needle assist housing is fitted onto the upper end of the trigger sleeve, and the lower end of the pusher core is axially locked to the trigger sleeve via a first locking structure. An unlocking block is provided at the lower outer edge of the needle pickup stage. When the needle assist device picks up a needle from the needle pickup stage, the unlocking block triggers the first locking structure and releases the axial restriction between the trigger sleeve and the pusher core. This needle assist device has high safety and effectively avoids accidental operation. When the needle assist device picks up the analyzer sensor, the unlocking block on the needle pickup stage will release the first locking structure, allowing the needle assist device to be activated.

[0011] Preferably, the first locking mechanism includes a first spring plate on the trigger sleeve and an opening groove on the pusher core. When locked, the top of the first spring plate is supported at the opening groove. The first spring plate and the opening groove cooperate to lock the trigger sleeve and the pusher core together, preventing the needle assist device from starting without unlocking.

[0012] Preferably, a spring is installed between the pusher core and the trigger sleeve; the upper end of the pusher core is locked to the trigger sleeve by a second locking mechanism. When the needle housing moves axially with the trigger sleeve, the second locking mechanism between the trigger sleeve and the pusher core is released, and the pusher core, under the action of the spring, moves the transmitter toward the skin. The second locking mechanism further improves the safety of the needle aid; the user can only unlock the second locking mechanism by pushing the needle housing and moving the trigger sleeve simultaneously.

[0013] Preferably, the second locking mechanism includes a second spring plate on the trigger sleeve, a retaining hole in the booster core, and a top block on the inner wall of the booster needle housing. During locking, the top block presses against the second spring plate and engages it in the retaining hole. When the trigger sleeve moves axially downward, the second spring plate disengages from the retaining hole of the booster core, allowing the booster core to be ejected. The locking structure of the second locking mechanism is compact and ingeniously designed. Only a set minimum force can unlock the second locking mechanism; without applying any force, the booster core will be firmly positioned on the trigger sleeve.

[0014] Preferably, the outer wall of the trigger sleeve is provided with an axially extending guide positioning hole, and a positioning block is fixed to the outer wall of the top of the booster core. The positioning block moves axially along the guide positioning hole. After the booster core is triggered and ejected, it will not detach from the trigger sleeve, and the two remain tightly connected, facilitating the secondary use of the needle assist device.

[0015] Preferably, the inner wall of the needle housing is provided with a push block, and the trigger sleeve has at least two push holes evenly distributed on it. The push block extends into the push hole and presses against the push core. The push block is used to push the push core and unlock the second locking mechanism on the one hand; on the other hand, it prevents the needle housing from rotating on the trigger sleeve, so that the trigger sleeve and the needle housing do not need to be designed with too many limiting structures in axial limiting.

[0016] Preferably, the inner wall of the needle housing is provided with at least two axial limiting blocks, and the outer wall of the trigger sleeve is provided with a number of stops equal to the number of axial limiting blocks. When the trigger sleeve is installed on the needle housing, the stops are located above the axial limiting blocks, and the stops and axial limiting blocks form axial limiting.

[0017] Preferably, the needle retrieval station has two U-shaped third spring pieces integrally formed around its perimeter. The number of these third spring pieces is at least two and they are evenly distributed around the perimeter of the station. An upper limit block and a lower limit block are provided on the inner wall of the lower mounting groove. The lower end of each third spring piece is positioned between the upper limit block and the lower limit block. The needle retrieval station and the needle retrieval box are connected by a snap-fit ​​mechanism, making the needle retrieval station easy to assemble and disassemble.

[0018] This utility model, by adopting the above technical solution, has significant technical effects:

[0019] This medical monitoring device integrates both the needle assist device and the analyte sensor into the needle retrieval box. It combines the traditional needle assist device cover and the outer shell of the needle retrieval box into a single design, allowing for a strong correlation between the transmitter and the analyte sensor. This reduces the probability of misplaced shipments and lowers management costs during the warehousing phase. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described in detail with reference to the embodiments.

[0035] Example 1

[0036] A medical monitoring device for continuous glucose monitoring mainly includes a needle assist device 1, a transmitter 2, and a needle retrieval box 3. The needle assist device 1 is a handheld implantable device that can house sensors. The transmitter 2 connects the sensors to a host computer, converts blood information, and sends the information to a terminal device. The needle retrieval box 3 is a sealed, sterile packaging box for storing analyte sensors. The transmitter 2 is mounted on the needle assist device 1, and the two are connected by a snap-fit ​​mechanism.

[0037] The needle collection box 3 includes an upper mounting slot 31 and a lower mounting slot 32. The upper mounting slot 31 is not connected to the lower mounting slot 32. The needle aid 1, with the transmitter 2, is installed on the upper mounting slot 31. The needle collection platform 4 is installed in the lower mounting slot 32. The analyzer sensor 5 is installed on the needle collection platform 4.

[0038] A sealing cover 6 is sealed at the port of the lower mounting groove 32 of the needle collection box 3, thereby forming a sealed space. The sealing cover 6 seals the needle collection stage 4 and the analyzer sensor 5 inside the lower mounting groove 32.

[0039] This medical monitoring device integrates both the needle assist device 1 and the analyzer sensor 5 into the needle retrieval box 3. It integrates the traditional needle assist device cover and the outer shell of the needle retrieval box into one design, and enables the transmitter 2 and the analyzer sensor 5 to be strongly correlated, thereby avoiding and reducing the probability of disordered shipments and reducing the management costs during the warehousing stage.

[0040] The bottom of the upper mounting groove 31 is provided with a support column 33 for supporting the transmitter 2. The support column 33 is integrally formed at the bottom of the upper mounting groove 31. When the needle aid 1 is installed on the needle collection box 3, the support column 33 is positioned under the transmitter 2. The support column 33 is used to support the transmitter 2 and prevent the transmitter 2 from falling off the needle aid 1 during transportation.

[0041] The needle assist device 1 includes a needle assist housing 11, a trigger sleeve 12, and a pusher core 13. The needle assist housing 11 is threadedly connected to the needle retrieval box 3. The needle assist housing 11 is fitted onto the upper end of the trigger sleeve 12. The lower end of the pusher core 13 is axially locked onto the trigger sleeve 12 by a first locking structure. In this embodiment, there are three first locking mechanisms arranged in a circumferential array. An unlocking block 41 is provided at the lower outer edge of the needle retrieval platform 4. The number of unlocking blocks 41 is equal to the number of the first locking mechanisms, i.e., there are three unlocking blocks 41. When the needle assist device 1 retrieves a needle from the needle retrieval platform 4, the unlocking block 41 triggers the first locking structure and releases the axial restriction between the trigger sleeve 12 and the pusher core 13. When the first locking structure is not unlocked, there is an unlocking space between the top of the needle assist housing 11 and the top of the trigger sleeve 12. The unlocking space provides an unlocking form for the first locking structure. That is, when the top of the needle assist housing 11 is attached to the top of the trigger sleeve 12, the first locking mechanism will be completely unlocked.

[0042] The first locking mechanism includes a first spring piece 121 disposed on the trigger sleeve 12 and an opening groove 131 disposed on the pusher core 13. The first spring piece 121 is integrally formed on the trigger sleeve 12. When locked, the top end of the first spring piece 121 is supported at the opening groove 131. The first spring piece 121 and the opening groove 131 cooperate to lock the trigger sleeve 12 and the pusher core 13 together, preventing the needle assist device 1 from starting without unlocking.

[0043] A spring is installed between the pusher core 13 and the trigger sleeve 12 (the spring is not shown in the attached diagram). The upper end of the pusher core 13 is locked to the trigger sleeve 12 by a second locking mechanism. When the needle housing 11 moves axially with the trigger sleeve 12, the second locking mechanism between the trigger sleeve 12 and the pusher core 13 is released, and the pusher core 13, under the action of the spring, moves the transmitter 2 toward the skin. The second locking mechanism further improves the safety of the needle aid 1. The user can only unlock the second locking mechanism by pushing the needle housing 11 and moving the trigger sleeve 12 simultaneously, thus preventing the pusher core 13 from being accidentally activated.

[0044] The second locking mechanism includes a second spring piece 122 on the trigger sleeve 12, a locking hole 132 on the push core 13, and a top block 113 on the inner wall of the needle housing 11. The second spring piece 122 is integrally formed on the trigger sleeve 12, the locking hole 132 is an elongated locking hole, and the top block 113 is integrally formed on the inner wall of the needle housing 11. When the second locking mechanism is locked, the top block 113 pushes against the second spring piece 122 and engages with the locking hole 132. After the first locking mechanism is unlocked, the push core 13 moves downward under the action of the spring until the second spring piece 122 contacts the upper edge of the locking hole 132. At this time, the needle housing 11 is pushed, and the needle housing 11 moves downward. The top block 113 also moves downward and separates from the second spring piece 122. The second spring piece 122 loses its limit and is pushed open by the push core 13, that is, the spring carries the push core 13 towards the skin end.

[0045] The outer wall of the trigger sleeve 12 is provided with two axially extending guide positioning holes 123 that penetrate the outer circumferential side wall of the trigger sleeve 12. The top outer wall of the booster core 13 is integrally formed with two positioning blocks 133, which move axially along the guide positioning holes 123. After the booster core 13 is triggered and ejected, it will not detach from the trigger sleeve 12; the two remain tightly connected, facilitating the secondary use of the needle assist device 1.

[0046] The inner wall of the needle housing 11 is provided with four axially extending push blocks 111. The trigger sleeve 12 has at least two push holes 124 evenly distributed on it, also four in number. The push blocks 111 extend into the push holes 124 and press against the booster core 13. The push blocks 111 are used to push the booster core 13 and unlock the second locking structure, causing the booster core 13 to move the transmitter 2. On the other hand, the push blocks 111 cooperate with the push holes 124 to radially limit the needle housing 11 on the trigger sleeve 12. The cooperation between the push blocks 111 and the push holes 124 prevents the needle housing 11 from rotating on the trigger sleeve 12. The needle housing 11 cannot rotate on the trigger sleeve 12, and the push blocks 111 can only move along the push holes 124. This is also to optimize the structure, so that the trigger sleeve 12 and the needle housing 11 do not need to be designed with too many limiting structures in axial limiting.

[0047] The inner wall of the needle housing 11 is provided with at least two axial limiting blocks 112. In this embodiment, there are four axial limiting blocks 112, which are evenly distributed on the needle housing 11. The outer wall of the trigger sleeve 12 is provided with a number of stops 125 equal to the number of axial limiting blocks 112. The four stops 125 are evenly distributed on the trigger sleeve 12. When the trigger sleeve 12 is installed on the needle housing 11, the stops 125 are located above the axial limiting blocks 112. The stops 125 and the axial limiting blocks 112 form axial limiting to prevent the trigger sleeve 12 from detaching from the needle housing 11.

[0048] Example 2

[0049] Example 2 is basically the same as Example 1, except that the needle collection platform 4 has a U-shaped third spring piece 42 integrally formed around its perimeter. There are at least two third spring pieces 42 and they are evenly distributed around the perimeter of the needle collection platform 4. There are four third spring pieces 42. The inner wall of the lower mounting groove 32 is provided with an upper limit block 34 and a lower limit block 35. The lower end of the third spring piece 42 is limited between the upper limit block 34 and the lower limit block 35. The needle collection platform 4 and the needle collection box 3 are connected by a snap-fit ​​method. The needle collection platform 4 is easy to assemble and disassemble.

[0050] Example 3

[0051] A method of using a medical monitoring device includes the following steps:

[0052] S1, Remove the sealing cover 6 from the needle collection box 3 to fully expose the needle collection platform 4;

[0053] S2, remove the needle aid 1 from the needle collection box 3 and install it on the needle collection platform 4, push the needle aid housing 11 to move along the axis, install the analyzer sensor 5 on the transmitter 2, and at the same time, the unlocking block 41 on the needle collection platform 4 unlocks the first locking mechanism, releasing the axial lock between the lower end of the booster core 13 and the trigger sleeve 12.

[0054] S3, after removing the needle, place the needle aid 1 on the skin tissue, push the needle aid shell 11, the needle aid shell 11 moves axially together with the trigger sleeve 12, the second locking mechanism between the trigger sleeve 12 and the push core 13 is released, the push core 13 moves to the skin tissue under the action of elasticity, and implants the analyzer sensor 5 into the skin tissue.

[0055] S4, remove the needle aid 1, the transmitter 2 separates from the push core 13, and the transmitter 2 is attached to the skin tissue.
