DETAILED DESCRIPTION

[0045] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0046] First embodiment

[0047] like Figure 1 As shown, the clamping structure 110 includes:

[0048] An auxiliary tube 111, wherein the auxiliary tube 111 is provided with a mounting channel 111a, wherein the mounting channel 111a is exposed at both ends of the auxiliary tube 111 in the axial direction;

[0049] A clamping block 112, wherein the clamping block 112 has opposite fitting plates 112a and a sliding point 112b, the clamping block 112 is inserted into the auxiliary tube 111, the fitting plate 112a is located in the installation channel 111a, and the sliding point 112b is located outside the auxiliary tube 111;

[0050] A transmission gear 113, wherein the transmission gear 113 is sleeved on the outside of the auxiliary cylinder 111, and a slide groove 113a is provided on the axial end surface of the transmission gear 113, and a sliding point 112b of the clamping block 112 is located in the slide groove 113a;

[0051] The power piece 116 is in transmission connection with the transmission gear 113 , and the power piece 116 drives the transmission gear 113 to rotate. The transmission gear 113 pulls the clamping block 112 to move the clamping block 112 along the radial direction of the auxiliary cylinder 111 .

[0052] The installation channel 111a can be used to arrange insulin injection pens, etc. The transmission gear 113 is driven to rotate by the power member 116, and the transmission gear 113 pulls the clamping block 111 to move along the radial direction of the auxiliary tube 111. When the clamping block 111 moves along the radial inner side of the auxiliary tube 111, the fitting plate 112a of the clamping block 111 fits the surface of the insulin injection pen and holds the insulin injection pen, thereby fixing the insulin injection pen to facilitate subsequent monitoring of the fixed insulin injection pen. When the power member 116 drives the transmission gear 113 to rotate in the opposite direction, the clamping block 111 moves along the radial outer side of the auxiliary tube 111, and the clamping block 111 releases the insulin injection pen to allow the insulin injection pen to be taken out of the installation channel 111a.

[0053] like Figure 1 As shown, the auxiliary barrel 111 is tubular, that is, the mounting channel 111a is exposed at both ends of the auxiliary barrel 111 in the axial direction, so that the insulin injection pen can be inserted into the mounting channel 111a from any end of the auxiliary barrel 111 in the axial direction. The length of the auxiliary barrel 111 satisfies that when the insulin injection pen is fixed in the mounting channel 111a, the pen core and the dial of the insulin injection pen are exposed outside.

[0054] The auxiliary tube 111 is provided with a hole through which the clamping block 111 passes, the hole connects the installation channel 111a and the outside, the shape of the clamping block 111 matches the shape of the hole, and in one embodiment, the clamping block 111 and the hole are both rectangular. In another embodiment, the shape of any cross section of the clamping block 111 along the axial direction of the auxiliary tube 111 is the same, both are triangular, that is, the clamping block 111 is a triangular prism, in which case the hole is rectangular, the bottom of the triangle of the clamping block 112 is connected to the bonding plate 112a, and the top of the triangle of the clamping block 112 is connected to the sliding point 112b.

[0055] Preferably, the size of the fitting plate 112a is slightly larger than the size of the hole to prevent the fitting plate 112a from being removed from the installation channel 111a and unable to be reset. The fitting plate 112a is arc-shaped to fit the circular outer surface of the insulin injection pen.

[0056] like Figure 1The transmission gear 113 is sleeved on the outside of the auxiliary cylinder 111, and the transmission gear 113 can rotate relative to the auxiliary cylinder 111 to pull the clamping block 111. A sliding groove 113a is provided on the axial end surface of the transmission gear 113, and the sliding point 112b of the clamping block 112 is located in the sliding groove 113a.

[0057] refer to Figure 2 and Figure 3 , the distance from the slide groove 113a to the center of the circle of the transmission gear 113 gradually increases from one end to the other end. Specifically, the distance from the slide groove 113a to the center of the circle of the transmission gear 113 gradually increases from one end and in a clockwise direction to the other end. Since the distance from the other end of the slide groove 113a to the center of the circle of the transmission gear 113 is the largest, when the sliding point 112b of the clamping block 111 is located at the other end of the slide groove 113a, the clamping block 111 is in a relaxed state, and since the distance from one end of the slide groove 113a to the center of the circle of the transmission gear 113 is the smallest, when the sliding point 112b of the clamping block 111 is located at one end of the slide groove 113a, the clamping block 111 is in a clamped state. Based on this, the transmission gear 113 is moved along Figure 2 In the counterclockwise state shown in FIG. 1 , until the sliding point 112 b of the clamping block 111 is located at the other end of the slide groove 113 a, the clamping block 111 can be moved radially and outwardly to release the clamping of the insulin injection pen, and the transmission gear 113 can be moved radially and outwardly. Figure 2 In the clockwise state shown, until the sliding point 112b of the clamping block 111 is located at one end of the sliding groove 113a, the clamping block 111 can be moved radially and inwardly to clamp the insulin injection pen.

[0058] like Figure 1 As shown, the fixing effect of the insulin injection pen is improved by increasing the number of the clamping blocks 111. Each of the clamping blocks 111 corresponds to one of the slide grooves 113a, that is, the sliding point 112b of each of the clamping blocks 111 is located in one of the slide grooves 113a.

[0059] In this embodiment, the number of the clamping blocks 112 is multiple and divided into two groups. The two groups of clamping blocks 112 are arranged on both sides of the axial direction of the transmission gear 113. The number of the clamping blocks 112 in each group is multiple and arranged at intervals along the circumferential direction of the transmission gear 113. As a preferred embodiment, the number of the clamping blocks 112 in each group is three and they are arranged at equal intervals along the circumferential direction of the transmission gear 113, that is, the angle between two adjacent clamping blocks 112 is 120°, which ensures uniform clamping force and improves the clamping effect.

[0060] The bonding plate 112a is made of rubber to protect the insulin injection pen. The clamping structure 110 is used to properly clamp the insulin injection pen 200 after it is inserted into the installation channel 111a, ensuring that the insulin injection pen 200 will not move relative to the device during use without damaging the insulin injection pen 200.

[0061] like Figure 1 As shown, the clamping structure 110 further includes:

[0062] A driving gear 114, wherein the driving gear 114 is meshed with the transmission gear 113;

[0063] The reducer 115 is connected between the driving gear 114 and the power member 116 .

[0064] The power member 116 may be a micro motor, the output force of which is decelerated by the reducer 115 and drives the driving gear 114 to rotate, and the driving gear 114 drives the transmission gear 113 to rotate. The diameter of the transmission gear 113 is larger than the diameter of the driving gear 114, which can be adjusted according to design requirements.

[0065] like Figure 1 As shown, the clamping structure 110 further includes a power fixing frame 117, and the power fixing frame 117 includes:

[0066] An arc plate 117a, wherein the arc plate 117a is fixed on the outer wall of the auxiliary tube 111;

[0067] The vertical plate 117b is connected to the arc plate 117a, the driving gear 114 and the transmission gear 113 are located on the front side of the vertical plate 117b, the power member 116, the reducer 115 and the arc plate 117a are located on the rear side of the vertical plate 117b, the power member 116 is fixed on the vertical plate 117b, and the reducer 115 is located between the power member 116 and the vertical plate 117b.

[0068] The arc plate 117a and the vertical plate 117b can be integrally connected and formed by sheet metal welding or the like.

[0069] It should be noted that the clamping structure 110 can clamp other components in addition to the insulin injection pen, etc. In addition, the mounting channel 111a, in addition to being circular, can also be adaptively adjusted to fix components of corresponding shapes.

[0070] In summary, the components to be fixed are arranged in the installation channel 111a, and then the power member 116 drives the transmission gear 113 to rotate, and the transmission gear 113 pulls the clamping block 111 to move radially inward along the auxiliary tube 111, so that the clamping block 111 clamps the components, so that the components are fixed stably, and the displacement of the components during subsequent monitoring is prevented, thereby affecting the monitoring effect. The transmission gear 113 is driven to rotate in the opposite direction, and the transmission gear 113 pulls the clamping block 111 to move radially outward along the auxiliary tube 111 to release the clamping of the components by the clamping block 111, and the components can be removed from the installation channel 111a at this time, which is convenient and quick to use.

[0071] Second embodiment

[0072] like Figures 4 to 8 As shown, the monitoring device 100 for the insulin injection pen includes the clamping structure 110 of the above embodiment, and the monitoring device 100 for the insulin injection pen further includes:

[0074] An image capturing system 120, wherein the image capturing system 120 comprises a camera 1 121 and a camera 2 122, wherein the camera 1 121 and the camera 2 122 are respectively fixed on opposite sides of the housing 150;

[0075] An interactive system 130, the interactive system 130 includes a display screen 131, a control button 132 and a speaker 133, and the display screen 131, the control button 132 and the speaker 133 are fixed on the surface of the housing 150;

[0076] The computing control communication unit 140 is disposed inside the housing 150 , and the computing control communication unit 140 is connected to the display screen 131 , the control button 132 , the speaker 133 and the power member 116 , respectively.

[0077] The housing 150 is used to carry and fix the clamping structure 110, the image capture system 120, the interactive system 130 and the computing control communication unit 140. The camera 1 121 and the camera 2 122 are used to collect real-time images of the insulin injection pen 200, including the insertion status of the insulin injection pen 200, the pen core 201 and the dial 202. The computing control communication unit 140 is used to calculate the real-time picture collected by the image capture system 120, extract information such as the dial scale and the remaining amount of medicine, and is also used to calculate the clamping status of the clamping structure 110, display information through the display screen 131 of the interactive system 130, and broadcast information through the speaker 133. The control button 132 is the on / off button of the power member 116, which improves the convenience of use and facilitates patients to accurately and safely perform insulin injection operations.

[0078] like Figure 5 As shown, the housing 150 includes:

[0079] A top plate 151, on which the display screen 131 is arranged;

[0080] Two side plates 152, the two side plates 152 are respectively connected to both sides of the top plate 151 in the length direction, the two ends of the auxiliary cylinder 111 in the axial direction are respectively connected to the two side plates 152, the power member 116 is located between the top plate 151 and the auxiliary cylinder 111, the outer surface of one side plate 152 is provided with the camera 1 121, and the outer surface of the other side plate 152 is provided with the camera 2 122;

[0081] The enclosure 153 has two ends connected to the two sides of the top plate 151 in the width direction, the enclosure 153 surrounds the periphery of the clamping structure 110 and is respectively connected to the two side plates 152 , and the outer surface of the enclosure 153 is provided with a control button 132 and a speaker 133 .

[0082] The top plate 151 is completely covered by the display screen 131 , providing a larger screen for the user, so that the insulin cartridge dosage image, the dial scale image, and the image abnormality prompt information processed and extracted by the computing control communication unit 140 can be displayed through the display screen 131 .

[0083] The outer surface of the enclosure 153 is provided with a control button 132 and a speaker 133. The speaker 133 is used to broadcast the scale change of the dial in real time, as well as the abnormal dosage of the insulin pen cartridge 201 and the insertion of the insulin injection pen. The control button 132 is used to send a relaxation and clamping command that meets the intuitive operation to the computing control communication unit 140.

[0084] The computing control communication unit 140 is located inside the housing 150, and is used to receive and process the real-time images captured by the camera 1 121 and the camera 2 122, and automatically determine the insertion direction of the insulin injection pen and then change the extracted content of the real-time images on both sides, so that the device can be used normally regardless of the direction from which the insulin injection pen is inserted into the auxiliary cylinder. For example, if the computing control communication unit 140 determines that the camera 1 121 is opposite to the refill 201 of the insulin injection pen 200, and the camera 2 122 is opposite to the dial 202 of the insulin injection pen 200, then it is determined that the insulin injection pen 200 is inserted into the installation channel 111a of the auxiliary cylinder 111 from the direction of the camera 2 122 to the camera 1 121, and the names of the images captured by the camera 1 121 and the camera 2 122 are associated.

[0085] The computing control communication unit 140 is connected to the power part 116, and is used to control the rotation of the power part 116 after receiving the loosening or clamping command from the control button 132, and monitor the driving current of the power part 116 in real time. When the current exceeds the threshold, it is determined that the motor has stalled after rotating to a certain limit, and then it is determined that it has been clamped or released.

[0086] refer to Figure 6 The distance between the two side panels 152 is the largest near the top panel 151 , so the camera 1 121 and the camera 2 122 can be installed near the top panel 151 , so as to ensure that they can capture the images of the pen core 201 and the dial 202 .

[0087] Furthermore, the side panel 152 has a slope 152a, and the slope 152a is arranged close to the top panel 151, wherein the camera 1 121 is arranged on the slope 152a of one of the side panels 152, and the camera 2 122 is arranged on the slope 152a of the other side panel 152, so as to further increase the collection field of view.

[0089] The computing control communication unit 140 can also be connected to a user terminal such as a mobile phone or a computer to display and broadcast information through the user terminal, thereby further increasing the usage functions.

[0090] In summary, the clamping structure 110, the image capture system 120, the interactive system 130 and the computing control communication unit 140 are integrated in the housing 150, which makes reasonable use of space and has a compact structure. The camera 1 121 and the camera 2 122 are used to collect real-time images of the insulin injection pen 200, and then the computing control communication unit 140 calculates and extracts information such as the dial scale and the remaining amount of medicine, and finally displays the information on the display screen 131 of the interactive system 130 and broadcasts the information on the speaker 133, so that the user can perform the injection operation accurately and safely.
