Description

Technical Field

[0001] The present invention belongs to the technical field of blood glucose detection, and particularly relates to a continuous blood glucose meter for intensive care units. Background Art

[0002] Due to stress reactions and other reasons, patients in intensive care units are prone to elevated blood glucose. Hyperglycemia can increase the risk of infection and affect wound healing. Some patients also show hypoglycemia due to organ dysfunction. Therefore, it is necessary to use a blood glucose meter to perform rapid bedside blood glucose detection, and the detection principle is reflectance photochemistry or electrochemistry.

[0003] The specific process of the blood glucose meter detecting blood glucose is as follows: a blood collection needle pricks the finger for blood collection, the blood glucose test strip absorbs the blood, the blood undergoes a chemical reaction with a specific enzyme, the blood glucose test strip is inserted into the slot of the blood glucose meter, and the blood glucose meter displays the blood glucose value.

[0004] A Chinese patent with the patent publication number CN105572377B discloses a blood glucose meter, which includes a main body, a pressing mechanism, an elastic mechanism and a limiting mechanism. After the blood glucose test strip is inserted, it is pressed by a pressing member, and when the elastic force is released, the blood glucose test strip is ejected. However, each time blood glucose is detected, the blood glucose test strip needs to be manually inserted, and it is difficult to automatically replace a new blood glucose test strip, resulting in difficulty in continuously performing multiple blood glucose detections, and the efficiency of blood glucose detection needs to be improved. Summary of the Invention

A lifting plate that slides up and down is provided on the fixing column. A return spring is connected between the lifting plate and the fixing column. Two arc-shaped clamping blocks made of rubber are connected to the lifting plate. A blood collection needle is placed between the two arc-shaped clamping blocks. When the blood collection needle descends, it will extend into the finger slot.

[0012] Further, the continuous blood glucose meter for the intensive care unit further includes a pressing mechanism. The pressing mechanism includes a fixing rod. A fixing rod with a fixed position is provided below the lower shell. Two sliding frames that slide back and forth are provided on the fixing rod. A compression spring is connected between the sliding frame and the fixing rod. Pressing blocks are connected to the sliding frames.

Detailed Embodiments

[0027] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1: A continuous blood glucose meter for the intensive care unit, referring to Figures 1-6 , includes a housing, a blood glucose detector 3, a translation rod 4, a driving mechanism, a push block 5, a square frame 6, a moving block 7, a blood glucose detection plate 71 and a slider 8. Since human fingers vary, the housing is made transparent for easy visual observation of blood collection. The housing includes an upper shell 1 and two lower shells 2 arranged at intervals. The two lower shells 2 are respectively connected to the front and rear parts of the upper shell 1. Finger grooves 20 are provided on the right parts of the two lower shells 2. A blood glucose detector 3 is installed on the left part of the housing. A translation rod 4 driven by a driving mechanism is provided below the blood glucose detector 3. The driving mechanism includes a guide rail 41 and a lead screw motor 42. A guide rail 41 is connected between the bottoms of the two lower shells 2. The lead screw motor 42 is installed on the guide rail 41. The translation rod 4 is installed on the lead screw motor 42; the right end of the translation rod 4 is connected to a push block 5 extending into the housing. A square frame 6 with an upper opening and a lower opening is connected to the middle of the upper shell 1. Vertical guide grooves 60 are opened on the front and rear inner walls of the square frame 6. A row of moving blocks 7 sliding on the guide grooves 60 are placed inside the square frame 6. A placement groove 50 for the moving blocks 7 to be embedded is opened on the push block 5, so that the push block 5 can drive the moving blocks 7 embedded in the placement groove 50 to move together. Blood glucose detection plates 71 are provided on the moving blocks 7. The right end of the blood glucose detector 3 has a slot for the blood glucose detection plate 71 to be inserted. Sliders 8 that slide back and forth are provided on the lower parts of the front and rear sides of the square frame 6. Tensile springs are fixedly connected between the sliders 8 and the square frame 6. Trapezoidal parts 81 are provided at the right ends of the sliders 8. The front and rear sides of the push block 5 respectively abut against the two trapezoidal parts 81. The edges of the moving blocks 7 are chamfered; a pair of limiting parts 9 with inclined surfaces 91 at the ends are provided on the upper parts of the sliders 8. As Figure 8 shown, square holes 61 and square grooves 62 are opened on the lower parts of the front and rear sides of the square frame 6. The two upper limiting parts 9 respectively extend into the inside of the square frame 6 through the two square holes 61, and the two lower limiting parts 9 respectively extend into the inside of the square frame 6 through the two square grooves 62. The limiting parts 9 are used to limit the blood glucose detection plate 71.

[0029] Referring to Figure 2 and Figure 3 , the continuous blood glucose meter for the intensive care unit further includes a guiding block 31. A guiding block 31 for guiding the blood glucose detection plate 71 is fixedly connected below the slot of the blood glucose detector 3. The top surface of the guiding block 31 is inclined. When the blood glucose detection plate 71 is inserted into the blood glucose detector 3, the guiding block 31 plays a guiding role for the blood glucose detection plate 71.

[0030] Referring to Figures 1-4, the continuous blood glucose meter for the intensive care unit further includes a fixed column 101, a lifting plate 102, an arc-shaped clamping block 103 and a blood collection needle 104. A fixed column 101 is fixedly connected to the right side of the top of the upper shell 1. A lifting plate 102 that slides up and down is provided on the fixed column 101. A reset spring is fixedly connected between the lifting plate 102 and the fixed column 101. Arc-shaped clamping blocks 103 made of rubber are connected to both the upper and lower parts of the lifting plate 102. A blood collection needle 104 is placed between the two arc-shaped clamping blocks 103. When the blood collection needle 104 descends, it will extend into the finger groove 20.

[0031] Reference Figure 1 , Figure 2 and Figure 7 , the continuous blood glucose meter for the intensive care unit further includes a pressing mechanism. The pressing mechanism includes a fixed rod 111, a sliding frame 112 and a pressing block 113. A fixed rod 111 with a fixed position is provided below the lower shell 2. The fixed rod 111 is connected to the right side of the guide rail 41. Two sliding frames 112 that slide back and forth are provided on the fixed rod 111. A compression spring is fixedly connected between the sliding frame 112 and the fixed rod 111. Pressing blocks 113 are fixedly connected to the right ends of the sliding frames 112. Through holes for the pressing blocks 113 to extend into are opened at the finger grooves 20 of the lower shell 2.

[0032] Reference Figure 2 and Figure 3 , the continuous blood glucose meter for the intensive care unit further includes a sliding rod 121 and a positioning rod 122. A sliding rod 121 that slides left and right is provided outside the guide rail 41. A return spring is fixedly connected between the sliding rod 121 and the guide rail 41. The right end of the sliding rod 121 is connected to a positioning rod 122 located in the middle of the finger groove 20.

[0033] Initially, the lowermost moving block 7 is embedded in the placement groove 50 of the pushing block 5. The front and rear sides of the pushing block 5 squeeze the trapezoidal part 81, and the tension spring on the slider 8 is in a stretched state.

[0034] When it is necessary to detect the blood glucose of a patient, in the first step, a disposable pad paper adapted to the size of the finger groove 20 is placed at the finger groove 20. The patient places the disinfected finger on the disposable pad paper to avoid contaminating the finger groove 20 and reduce the subsequent cleaning steps until the finger contacts the positioning rod 122. The position of the finger is positioned through the positioning rod 122 so that the finger is directly below the blood collection needle 104. Press the lifting plate 102 to descend and then release the lifting plate 102. The lifting plate 102 quickly rises and resets through the reset spring. During this process, the arc-shaped clamping block 103 and the blood collection needle 104 descend and then rise and reset together with the lifting plate 102. The blood collection needle 104 extends into the finger groove 20 to collect blood from the patient's finger, thus completing the blood collection work.

[0035] In the second step, manually press the two sliding frames 112 to make the two sliding frames 112 approach each other in the front-back direction, compress the compression spring, drive the two pressing blocks 113 to approach each other and extend into the finger groove 20 from the through hole, and the pressing blocks 113 press the patient's finger to make the blood flow out.

[0036] In the third step, keep the patient's finger still, manually hold the housing and gently push it to the right. The positioning rod 122 is squeezed by the patient's finger, and the positioning rod 122 moves to the left relative to the housing, compressing the return spring. The right end of the blood glucose test strip 71 moves to directly above the patient's finger. Then, hold the housing and tilt it slightly to the lower right, so that the right end of the lowermost blood glucose test strip 71 contacts the patient's finger. The blood glucose test strip 71 absorbs the blood of the patient's finger, and the patient's finger can leave the finger groove 20. The sliding rod 121 and the positioning rod 122 are reset by the return spring.

[0037] In the fourth step, control the lead screw motor 42 to drive the translation rod 4 to translate to the left, drive the push block 5 to move to the left. The push block 5 will separate from the trapezoidal part 81, and the tension spring returns to its original state, so that the two sliders 8 approach each other in the front-back direction. The limiting parts 9 on the sliders 8 move towards the direction close to the blood glucose test strip 71. The two pairs of limiting parts 9 squeeze the second blood glucose test strip 71 from the bottom up through the inclined surface 91, and the second blood glucose test strip 71 from the bottom up is clamped by the two pairs of limiting parts 9, thereby limiting the blood glucose test strip 71. Since the lowermost moving block 7 is embedded in the placement groove 50 of the push block 5, the push block 5 drives the lowermost moving block 7 and the lowermost blood glucose test strip 71 with adsorbed blood to move to the left. The guide block 31 guides the blood glucose test strip 71 through the inclined top surface, so that the blood glucose test strip 71 is inserted into the blood glucose detector 3 from the slot, and the blood glucose detector 3 displays the blood glucose value, so as to know the blood glucose of the patient.

[0038] In the fifth step, control the lead screw motor 42 to move the translation rod 4, the push block 5, the lowermost moving block 7 and the blood glucose test strip 71 to the right. Since the edge of the moving block 7 is chamfered, the lowermost moving block 7 can smoothly cross the second moving block 7 from the bottom up until the lowermost blood glucose test strip 71 extends out of the housing. The two pairs of limiting parts 9 continue to limit the remaining blood glucose test strips 71, and take out the used blood glucose test strip 71.

[0039] In the sixth step, control the lead screw motor 42 to move the translation rod 4 and the push block 5 to the initial position. The push block 5 squeezes the trapezoidal part 81, and the slider 8 moves away from the remaining blood glucose test strips 71. The tension spring stretches, and the limiting parts 9 on the slider 8 no longer limit the blood glucose test strip 71. The blood glucose test strip 71 and the moving block 7 fall along the guide groove 60 by gravity, so that the next moving block 7 is embedded in the placement groove 50 of the push block 5. Finally, take the used blood collection needle 104 off the arc-shaped clamping block 103 and replace it with a new blood collection needle 104, and then the blood glucose of the patient can be detected again.

[0040] In this way, the blood glucose test strip 71 can be automatically inserted into and withdrawn from the blood glucose detector 3, the automatic replacement of the blood glucose test strip 71 can be completed, the continuous blood glucose detection can be realized, and the efficiency of blood glucose detection can be improved.

[0041] Embodiment 2: On the basis of Embodiment 1, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 8 , the continuous blood glucose monitor for the intensive care unit further includes a cover plate 13, a bump 133 and a guide bar 134. A cover plate 13 that can move left and right is provided above the square box 6. The bottom of the cover plate 13 has a strip portion 131 and a bent portion 132 located at the right end of the strip portion 131. A groove is opened at the left part of the upper opening of the square box 6, and a bump 133 and two guide bars 134 are connected in the groove. Sliding grooves that cooperate with the guide bars 134 are opened on both the front and rear sides of the strip portion 131, so that the cover plate 13 can only move left and right relative to the square box 6. When the bent portion 132 moves to the left, it will contact the right side of the bump 133. When the bent portion 132 moves to the right, it will contact the right inner wall of the square box 6, thereby restricting the moving range of the cover plate 13. The left part of the cover plate 13 has a pushing portion 135.

[0042] After the blood glucose test strip 71 in the square box 6 is used up, manually pull the pushing portion 135 to the left, and the cover plate 13 moves to the left through the cooperation of the guide bar 134 and the sliding groove on the strip portion 131 until the bent portion 132 contacts the bump 133, and the cover plate 13 no longer covers the upper opening of the square box 6. Put a new blood glucose test strip 71 into the square box 6, and push the pushing portion 135 to the right, and the cover plate 13 covers the upper opening of the square box 6, playing a role in dust and pollution prevention.

[0043] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present invention, and all of them should be covered by the protection scope of the present invention.
