Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a dynamic blood glucose monitor transmitter. Background Art

[0002] As people's living standards improve, they pay more attention to their health. For example, we need to regularly test the blood sugar index and pay attention to the blood sugar content. We usually monitor it through relevant monitoring instruments.

[0003] At present, the existing blood sugar monitoring method usually adopts a dynamic blood sugar monitoring system, which implants a blood sugar sensor under the skin, and the enzyme on the sensor reacts with the subcutaneous tissue fluid to detect the blood sugar value, and cooperates with the transmitter to send the blood sugar value to the terminal, which can continuously collect blood sugar data. Among them, the blood sugar monitoring transmitter can be used to accurately transmit and fix the sensor on the human skin. In actual use, people are prone to accidentally touch the button when they have not completely found the injection position, resulting in the sensor not being fixed on the human skin. Utility Model Content

[0004] The purpose of the utility model is to address the above problems in the prior art and to propose a transmitter for a dynamic blood glucose monitor.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] case;

[0007] A locking ring, the locking ring is rotatably mounted on the housing, the locking ring is fixedly connected to the housing in a pressing direction, and the rotation stroke of the locking ring includes a locking position and an unlocking position;

[0008] A push sleeve, wherein the push sleeve is movably installed in the shell along the pressing direction, and one of the push sleeve and the locking ring is provided with a locking buckle and the other is provided with a locking groove; when the locking ring is located at the locking position, the locking buckle is connected with the locking groove to limit the movement of the push sleeve along the pressing direction; when the locking ring is located at the unlocking position, the locking buckle is separated from the locking groove so that the push sleeve is allowed to move along the pressing direction.

[0009] Preferably, the device further comprises a trigger button, wherein the trigger button is located in the locking ring and connected to the ejection sleeve.

[0010] Preferably, the trigger button is provided with a first limit buckle, and the first limit buckle is connected to the locking ring.

[0011] Preferably, one of the inner wall of the shell and the locking ring is provided with a second limiting buckle and the other is provided with a second limiting groove, and the second limiting buckle is connected to the second limiting groove so that the locking ring and the shell are fixedly connected in the pressing direction.

[0012] Preferably, the locking ring is arranged at a port of the shell, and the pressing direction is set to be an axial direction of the shell.

[0013] Preferably, an upper spring cover, a return spring and a lower spring cover are installed in the ejection sleeve, and the upper spring cover is in contact with the trigger button; the two ends of the return spring are respectively in contact with the upper spring cover and the lower spring cover.

[0014] Preferably, a sensor is further included, a transmitter base is fixedly arranged at the bottom of the shell, the sensor is installed in the ejection sleeve and connected to the lower spring cover, and the other end of the ejection sleeve is installed in the emitter base.

[0015] Preferably, a protective sleeve is further included, and the protective sleeve is sleeved on the outer periphery of the shell.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. A locking ring is set at the trigger button. When the locking ring is in a locked state, it can effectively avoid the risk of launching the sensor without contact positioning due to misoperation.

[0018] 2. A fixing mechanism between the shell and the locking ring is formed by the second limiting buckle and the second limiting groove. The mutual engagement of the second limiting buckle and the second limiting groove ensures that the locking ring can rotate, but remains locked with the shell in the pressing direction.

[0019] 3. When the trigger button is pressed, pressure is transmitted to the ejection sleeve through the upper spring cover, the return spring and the lower spring cover. At this time, the return spring deforms and accumulates force. Once the pressing action is completed or reset is required, the return spring releases the stored energy and automatically pushes the ejection sleeve back to its original position, ensuring that the launcher quickly returns to the standby state and is ready for the next use.

DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figure 1-5 As shown, a continuous blood glucose monitor transmitter includes: a shell 100; a locking ring 200, the locking ring 200 is rotatably mounted on the shell 100, the locking ring 200 is fixedly connected to the shell 100 in the pressing direction, and the rotation stroke of the locking ring 200 includes a locking position and an unlocking position; a shooting sleeve 300, the shooting sleeve 300 is movably mounted in the shell 100 along the pressing direction, one of the shooting sleeve 300 and the locking ring 200 is provided with a locking buckle 210 and the other is provided with a locking groove 310; when the locking ring 200 is located in the locking position, the locking buckle 210 is connected to the locking groove 310 to limit the movement of the shooting sleeve 300 along the pressing direction; when the locking ring 200 is located in the unlocking position, the locking buckle 210 is separated from the locking groove 310 so that the shooting sleeve 300 is allowed to move along the pressing direction.

[0028] The locking ring 200 can be rotatably mounted at the port position of the housing 100, and the locking ring 200 can be rotated to reach a locked position or an unlocked position. In the locked position, the locking ring 200 is engaged with the corresponding locking buckle 210 and the locking groove 310 on the ejection sleeve 300 to prevent the ejection sleeve 300 from moving when it is not ready, thereby avoiding accidental firing of the sensor 500. When the user needs to push the ejection sleeve 300, the locking ring 200 can be turned to the unlocked position to release this restriction, so that the ejection sleeve 300 can smoothly move forward along the pressing direction.

[0029] This design can effectively prevent the sensor 500 from being fired without being correctly positioned due to an accidental touch of the button, thereby reducing the risk of incorrect operation during use. In addition, the ejection sleeve 300 and the locking ring 200 cooperate with each other through the locking buckle 210 and the locking groove 310 to achieve an efficient and reliable locking and unlocking mechanism. This method not only has high locking strength and good cost-effectiveness, but also has intuitive and simple locking and unlocking operations, reduces the possibility of operation failure, and enhances practicality.

[0030] The working mechanism of the continuous blood glucose monitor transmitter is as follows: in the initial state, the transmitter is in an inactive state, the locking ring 200 is in the locking position, the locking buckle 210 is engaged with the locking groove 310, and the ejection sleeve 300 is prevented from moving forward. The user needs to first rotate the locking ring 200 to the unlocking position, at which time the locking buckle 210 is separated from the locking groove 310, and the movement restriction of the ejection sleeve 300 is released. The ejection sleeve 300 can move in the pressing direction without any obstacles, and is ready to launch the sensor 500 and fix it on the skin.

[0031] On the basis of the above embodiment, a trigger button 400 is further included. The trigger button 400 is located in the locking ring 200 and connected to the ejection sleeve 300 .

[0032] The trigger button 400 is connected to the ejection sleeve 300, that is, the trigger button 400 can directly or indirectly push the ejection sleeve 300 to move along the pressing direction. After correctly unlocking, the user only needs to press the trigger button 400 to complete the fast and accurate firing and fixing steps of the sensor 500.

[0033] On the basis of the above embodiment, the trigger button 400 is provided with a first limit buckle 410, and the first limit buckle 410 is connected to the locking ring 200. The trigger button 400 fastens the locking ring 200 through the first limit buckle 410, so that the trigger button 400 cannot fall outward, and allows the trigger button 400 to be pressed inward.

[0034] Based on the above embodiment, one of the inner wall of the shell 100 and the locking ring 200 is provided with a second limiting buckle 220 and the other is provided with a second limiting groove 110, and the second limiting buckle 220 is connected to the second limiting groove 110 so that the locking ring 200 and the shell 100 are fixedly connected in the pressing direction.

[0035] In this embodiment, a fixing mechanism between the shell 100 and the locking ring 200 is formed by the second limiting buckle 220 and the second limiting groove 110. The mutual engagement of the second limiting buckle 220 and the second limiting groove 110 ensures that the locking ring 200 can rotate, but remains locked with the shell 100 in the pressing direction.

[0036] Based on the above embodiment, the locking ring 200 is disposed at the port of the housing 100, and the pressing direction is set to the axial direction of the housing 100. This embodiment further defines the pressing direction, which is preferably the direction from the port of the housing 100 to the inside along its axis.

[0037] like Figure 1-5 As shown, based on the above embodiment, an upper spring cover 320, a return spring and a lower spring cover 330 are installed in the ejection sleeve 300, and the upper spring cover 320 is in contact with the trigger button 400; the two ends of the return spring are respectively in contact with the upper spring cover 320 and the lower spring cover 330.

[0038] In this embodiment, an upper spring cover 320, a return spring and a lower spring cover 330 are designed. When the trigger button 400 is pressed, the trigger button 400 moves and transmits pressure to the ejection sleeve 300. At this time, the return spring deforms and accumulates force; once the pressing action is completed or reset is required, the return spring releases the stored energy and automatically pushes the ejection sleeve 300 back to its original position, ensuring that the launcher quickly returns to the standby state and is ready for the next use.

[0039] On the basis of the above embodiment, a sensor 500 is further included. A transmitter base 600 is fixedly arranged at the bottom of the housing 100. The sensor 500 is installed in the ejection sleeve 300 and connected to the lower spring cover 330. The other end of the ejection sleeve 300 is installed in the emitter base 600.

[0040] In the unlocked state, pressing the trigger button 400 will push the ejection sleeve 300 and the upper spring cover 320 in the ejection sleeve 300 to move along the guide hole of the housing 100 in the pressing direction until the bottom of the ejection sleeve 300 contacts the limit block on the inner wall of the transmitter base 600, and the ejection sleeve 300 will stop moving. Then, the lower spring cover 330 moves in the pressing direction under the action of the upper spring and the return spring until the sensor 500 is separated from the ejection sleeve 300, thereby achieving the launch of the sensor 500. When the user releases the trigger button 400, the transmitter is reset under the reaction of the return spring.

[0041] like Figure 1-5 As shown, based on the above embodiment, a protective cover 800 is further included, and the protective cover 800 is sleeved on the outer periphery of the shell 100 .

[0042] The protective cover 800 is sleeved on the outer periphery of the shell 100 to protect the entire transmitter. A desiccant 810 and a sensor needle holder 820 are also provided in the protective cover 800. The desiccant 810 keeps the sensor 500 dry; the sensor needle holder 820 ensures the normal use of the sensor 500 needle.

[0043] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0045] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
