Description

Technical Field

[0001] The present invention relates to medical instruments, and in particular to a medical monitoring device and a use method thereof. Background Art

[0002] The blood glucose meter implants the analyte sensor into the skin tissue to monitor the blood glucose level of the human body in real time. Due to the large fluctuations in the consistency of the current domestic analyte sensors during mass production, each sensor needs to be calibrated individually and generate a unique calibration code. For example, the announcement number CN105581781B is a medical device insert and a method for inserting and using a medical device, and its needle aid and needle removal box are designed to be separated. When the needle aid and the needle removal box are matched one-to-one, there is a certain probability that the product will be shipped in a chaotic manner due to factory management problems. At the same time, in order to solve this hidden danger, the classification management cost of the factory is increased. Summary of the invention

[0003] The present invention aims at the shortcomings of the prior art and provides a medical monitoring device and a method for using the same.

[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0005] A medical monitoring device comprises a needle assisting device, a transmitter and a needle removal box, wherein the transmitter is mounted on the needle assisting device;

[0006] The needle removal box comprises an upper mounting groove and a lower mounting groove, the needle assisting device with the transmitter is mounted on the upper mounting groove, the needle removal platform is mounted in the lower mounting groove, and the analyte sensor is mounted on the needle removal platform;

[0007] A sealing cover is sealed at the port of the lower mounting groove of the needle retrieval box, and the sealing cover seals the needle retrieval platform and the analyte sensor in the lower mounting groove.

[0008] This medical monitoring device integrates both the needle assist device and the analyte sensor on the needle removal box, integrates the cover of the traditional needle assist device and the outer shell of the needle removal box, and makes the transmitter and the analyte sensor have a strong correlation design, thereby avoiding and reducing the probability of chaotic shipments and reducing the management cost in the warehousing stage.

[0009] Preferably, a support column for supporting the transmitter is provided at the bottom of the upper mounting groove, and when the needle assisting device is installed on the needle removal box, the support column is placed under the transmitter. The support column is used to support the transmitter to prevent the transmitter from being separated from the needle assisting device during transportation.

[0010] Preferably, the needle-assisting device comprises a needle-assisting device shell, a trigger sleeve and a booster core, the needle-assisting device shell is sleeved on the upper end of the trigger sleeve, the lower end of the booster core is axially locked on the trigger sleeve through a first locking structure, and an unlocking block is provided at the outer edge of the lower end of the needle-removing platform. When the needle-assisting device removes the needle from the needle-removing platform, the unlocking block triggers the first locking structure and releases the axial limit between the trigger sleeve and the booster core. The needle-assisting device has high safety and effectively avoids misoperation. When the needle-assisting device grabs the analyte sensor again, the unlocking block on the needle-removing platform will release the first locking structure, and the needle-assisting device can be started.

[0011] Preferably, the first locking mechanism includes a first spring sheet provided on the trigger sleeve and an opening slot provided on the booster core, and when locked, the top end of the first spring sheet is supported at the opening slot.

The second locking mechanism further improves the safety of the auxiliary needle device, and the user can unlock the second locking mechanism only by pushing the auxiliary needle shell and driving the trigger sleeve to move at the same time.

[0013] Preferably, the second locking mechanism comprises a second spring sheet provided on the trigger sleeve, a clamping hole provided on the booster core and a top block provided on the inner wall of the auxiliary needle housing. When locked, the top block clamps the second spring sheet on the clamping hole. When the trigger sleeve moves axially downward, the second spring sheet will be separated from the clamping hole of the booster core, so that the booster core can be ejected. The locking structure of the second locking mechanism is compact and the layout is exquisite. Only by applying a set minimum force can the second locking mechanism be unlocked. If no booster core is applied, it will be firmly positioned on the trigger sleeve.

After the booster core is triggered and ejected, it will not separate from the trigger sleeve, and the two are still tightly connected together, which is convenient for the secondary use of the needle assist device.

[0015] Preferably, a push block is provided on the inner wall of the auxiliary needle shell, and at least two push holes are evenly distributed on the trigger sleeve. The push block extends into the push hole and presses against the auxiliary core. The push block is used to push the auxiliary core and unlock the second locking mechanism on the one hand; on the other hand, it prevents the auxiliary needle shell from rotating on the trigger sleeve, so that there is no need to design too many limiting structures in the axial limiting of the trigger sleeve and the auxiliary needle shell.

[0016] Preferably, a third spring piece in the shape of "U" is integrally formed around the needle retrieval table, the number of the third spring pieces is at least two and they are evenly distributed around the needle retrieval table, an upper limit block and a lower limit block are provided on the inner wall of the lower mounting groove, and the lower end of the third spring piece is limited between the upper limit block and the lower limit block.

[0019] S2, remove the needle assisting device from the needle retrieval box and install it on the needle retrieval table, push the axis of the needle assisting shell to move, install the analyte sensor on the transmitter, and at the same time, the unlocking block on the needle retrieval table unlocks the first locking mechanism to release the axial locking between the lower end of the boosting core and the trigger sleeve;

[0020] S3, placing the needle-assisting device after needle removal on the skin tissue, pushing the needle-assisting shell, the needle-assisting shell and the trigger sleeve move axially together, the second locking mechanism between the trigger sleeve and the boosting core is released, the boosting core moves to the skin tissue under the action of elastic force, and the analyte sensor is implanted into the skin tissue;

[0038] The following is combined with Figure 1-7 The present invention is further described in detail with examples.

[0039] Example 1

[0040] A medical monitoring device, which is used for dynamic blood glucose detection equipment, mainly includes a needle assisting device 1, a transmitter 2 and a needle removal box 3. The needle assisting device 1 is a handheld implant device, which can be equipped with a sensor. The transmitter 2 is a device for connecting the sensor to a host computer, converting blood information, and sending information to a terminal device. The needle removal box 3 is a sealed sterile packaging box for storing an analyte sensor. The transmitter 2 is installed on the needle assisting device 1, and the two are connected by snapping.

[0041] The needle removal box 3 includes an upper mounting groove 31 and a lower mounting groove 32. The upper mounting groove 31 is not connected to the lower mounting groove 32. The needle assisting device 1 with the transmitter 2 is installed on the upper mounting groove 31. The lower mounting groove 32 is provided with a needle removal table 4, on which an analyte sensor 5 is installed.

[0042] A sealing cover 6 is sealed at the end of the lower mounting groove 32 of the needle retrieval box 3 to form a closed space. The sealing cover 6 seals the needle retrieval platform 4 and the analyte sensor 5 in the lower mounting groove 32 .

[0043] The medical monitoring device integrates the needle assisting device 1 and the analyte sensor 5 on the needle removal box 3, integrates the cover of the traditional needle assisting device and the shell of the needle removal box, and makes the transmitter 2 and the analyte sensor 5 have a strong correlation design, thereby avoiding and reducing the probability of chaotic shipments and reducing the management cost at the warehousing stage.

[0044] A support column 33 for supporting the launcher 2 is provided at the bottom of the upper mounting groove 31. The support column 33 is integrally formed at the bottom of the upper mounting groove 31. When the needle assisting device 1 is installed on the needle removal box 3, the support column 33 is placed under the launcher 2. The support column 33 is used to support the launcher 2 to prevent the launcher 2 from separating from the needle assisting device 1 during transportation.

[0045] The needle-assisting device 1 comprises a needle-assisting housing 11, a trigger sleeve 12 and a booster core 13. The needle-assisting housing 11 is threadedly connected to the needle-removing box 3. The needle-assisting housing 11 is sleeved on the upper end of the trigger sleeve 12. The lower end of the booster core 13 is axially locked on the trigger sleeve 12 through a first locking structure. In this embodiment, there are three first locking mechanisms arranged in a circular array. An unlocking block 41 is provided at the outer edge of the lower end of the needle-removing platform 4. The number of the unlocking blocks 41 is equal to the number of the first locking mechanisms, that is, the number of the unlocking blocks 41 is 3. When the needle-assisting device 1 removes the needle from the needle-removing platform 4, the unlocking block 41 triggers the first locking structure and releases the axial limit between the trigger sleeve 12 and the booster core 13. When the first locking structure is not unlocked, an unlocking space is provided between the top of the needle-assisting housing 11 and the top of the trigger sleeve 12. The unlocking space is provided to unlock the first locking structure, that is, when the top of the needle-assisting housing 11 is attached to the top of the trigger sleeve 12, the first locking mechanism will be completely unlocked.

[0046] The first locking mechanism includes a first elastic piece 121 provided on the trigger sleeve 12 and an opening groove 131 provided on the boosting core 13. The first elastic piece 121 is integrally formed on the trigger sleeve 12. When locked, the top end of the first elastic piece 121 is supported at the opening groove 131. The first elastic piece 121 cooperates with the opening groove 131 to lock the trigger sleeve 12 and the boosting core 13 together, thereby preventing the needle assisting device 1 from being activated without unlocking.

[0047] A spring is installed between the booster core 13 and the trigger sleeve 12, but the spring is not shown in the attached drawings; the upper end of the booster core 13 is locked to the trigger sleeve 12 through a second locking mechanism. When the auxiliary needle shell 11 moves axially with the trigger sleeve 12, the second locking mechanism between the trigger sleeve 12 and the booster core 13 is released, and the booster core 13 moves toward the skin position with the transmitter 2 under the action of the spring. The second locking mechanism further improves the safety of the needle assisting device 1. The user can only unlock the second locking mechanism by pushing the auxiliary needle shell 11 and driving the trigger sleeve 12 to move at the same time, so as to avoid the booster core 13 from being accidentally started.

[0048] The second locking mechanism includes a second spring piece 122 provided on the trigger sleeve 12, a clamping hole 132 provided on the boosting core 13, and a top block 113 provided on the inner wall of the auxiliary needle housing 11. The second spring piece 122 is integrally formed on the trigger sleeve 12, the clamping hole 132 is a long strip clamping hole, and the top block 113 is integrally formed on the inner wall of the auxiliary needle housing 11. When the second locking mechanism is locked, the top block 113 clamps the second spring piece 122 on the clamping hole 132. After the first locking mechanism is unlocked, the boosting core 13 moves downward under the action of the spring until the second spring piece 122 contacts the upper edge of the clamping hole 132. At this time, the auxiliary needle housing 11 is pushed again, the auxiliary needle housing 11 moves downward, the top block 113 also moves downward and separates from the second spring piece 122, and the second spring piece 122 loses its limit and will be flushed by the boosting core 13, that is, the spring moves the boosting core 13 toward the skin end. The outer wall of the trigger sleeve 12 is provided with an axially extending guide positioning hole 123, the number of which is two and passes through the outer circumferential side wall of the trigger sleeve 12, and the outer wall of the top end of the booster core 13 is integrally formed with a positioning block 133, the number of which is also two, and the positioning block 133 moves axially along the guide positioning hole 123. After the booster core 13 is triggered and ejected, it will not be separated from the trigger sleeve 12, and the two are still tightly connected together, which is convenient for the secondary use of the needle-assisting device 1.

[0049] The inner wall of the auxiliary needle housing 11 is provided with an axially extending push block 111, and the number of the push blocks 111 is four. The trigger sleeve 12 is evenly provided with at least two push holes 124, and the number of the push holes 124 is also four. The push block 111 extends into the push hole 124 and presses against the booster core 13. On the one hand, the push block 111 is used to push the booster core 13 and unlock the second locking structure, and the booster core 13 drives the transmitter 2 to move; on the other hand, the push block 111 cooperates with the push hole 124 to radially limit the auxiliary needle housing 11 on the trigger sleeve 12. The push block 111 cooperates with the push hole 124 to prevent the auxiliary needle housing 11 from rotating on the trigger sleeve 12. The auxiliary needle housing 11 cannot rotate on the trigger sleeve 12, and the push block 111 can only move along the push hole 124. This is also to optimize the structure, so that the trigger sleeve 12 and the auxiliary needle housing 11 do not need to design too many limiting structures in the axial limiting.

[0050] At least two axial limit blocks 112 are provided on the inner wall of the auxiliary needle housing 11. In this embodiment, the number of the axial limit blocks 112 is four and they are evenly distributed on the auxiliary needle housing 11. The outer wall of the trigger sleeve 12 is provided with a number of stops 125 equal to the axial limit blocks 112. The four stops 125 are evenly distributed on the trigger sleeve 12. When the trigger sleeve 12 is installed on the auxiliary needle housing 11, the stop block 125 is arranged above the axial limit block 112. The stop block 125 and the axial limit block 112 form an axial limit to prevent the trigger sleeve 12 from detaching from the auxiliary needle housing 11.

[0051] Example 2

[0052] The features of Example 2 are basically the same as those of Example 1, except that a third spring piece 42 in the shape of a "U" is integrally formed around the needle removal table 4. The number of the third spring pieces 42 is at least two and they are evenly distributed around the needle removal table 4. The number of the third spring pieces 42 is four. An upper limit block 34 and a lower limit block 35 are provided on the inner wall of the lower mounting groove 32. 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 removal table 4 is connected to the needle removal box 3 by snapping, and the needle removal table 4 is easy to disassemble and assemble.
