Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an auxiliary detection device for diabetic microangiopathy. Background Art

[0002] Diabetes is a group of metabolic diseases characterized by high blood sugar. Based on a search for the detection of diabetic microvascular lesions, a Chinese utility model patent was found, with its authorization publication number CN216317812U. It discloses a diabetic microvascular lesion detection auxiliary device. Through the setting of a strap, an airbag and a pressure ball, it can effectively replace the operation of tying a compression cuff by personnel. At the same time, it can adjust the pressing force, which is easy to use and solves a series of inconveniences caused by the need for nurses to manually tie a compression cuff when drawing blood. However, when using it, it still requires the nurse to use a strap to fix the patient's arm, and then press the pressure ball to pressurize the airbag. The whole process still requires manual operation by the nurse, with a low degree of automation and low efficiency.

[0003] Based on the search for the automated use of the cuff, a Chinese utility model patent with the authorization announcement number CN216854772U was found, which discloses a cuff with automatic adjustment and high safety. When in use, two electric telescopic rods drive the A end and the B end of the cuff body to move outward, so that the air bag on the inner wall of the cuff body fits the patient's limbs, and then the inflation valve is opened to inject gas into the air bag to complete the binding and compression of the patient's limbs. Although this cuff technology can realize the automated binding and compression of the patient's limbs, it still has some shortcomings: according to the description of the patent document and the attached Figure 4 It can be seen that the main body of the cuff is made of elastic materials such as plastic or annular reed with a certain hardness. It is well known that the airbag is generally made of elastic and soft materials such as rubber. Therefore, when in use, the movement of the B end of the cuff main body will inevitably generate sliding friction with the airbag. Long-term use can easily cause the airbag to be worn by the B end of the cuff main body. In mild cases, it can easily cause the airbag to be worn thin, affecting the effect of the airbag in binding and compressing the patient's limbs. In severe cases, it can easily cause the airbag to rupture and cannot continue to be used. Therefore, there is room for improvement; in the binding process after the patient's limb passes through the cuff main body, the patient's limb will inevitably come into contact with the ring. Since the skin and flesh are soft, the ring can easily hit the patient under the binding and compression, causing pain to the patient. If the ring is cracked due to long-term use, the cracks will also pinch the skin and flesh, making the pain more severe. There is room for improvement.

[0004] Based on the above, the present invention proposes an auxiliary detection device for diabetic microangiopathy. Summary of the Invention

[0005] In order to solve the problem mentioned in the above background that the movement of the B end of the compression cuff body will inevitably generate sliding friction with the airbag, which may easily cause the airbag to be worn. In mild cases, the airbag may be worn thin, affecting the effect of the airbag in binding and compressing the patient's limbs. In severe cases, the airbag may easily rupture and cannot be used anymore. In addition, the ring may easily hurt the patient, causing discomfort to the patient.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments. Example

[0021] Reference Figure 1-Figure 7 A diabetic microangiopathy auxiliary detection device includes a base 100, a column 101 is provided on the upper surface of the base 100, a supporting seat 102 is provided at the upper end of the column 101, a mounting seat 1022 is provided on the supporting seat 102, and a bundling component 105 is provided on the mounting seat 1022.

[0022] The binding assembly 105 includes a compression cuff 1051 and a driving component 1052. The driving component 1052 is used to drive the compression cuff 1051 to be bound around the patient's limb to achieve automatic binding.

[0023] Reference Figure 3 and Figure 4 The compression cuff 1051 includes an outer sheet 1051b and a connecting plate 1051e.

[0024] The connecting plate 1051e can be driven by the driving component 1052 to move in the vertical direction.

[0025] A fixed pulley 1051a is provided on the mounting seat 1022 . The axis of the fixed pulley 1051a is arranged horizontally. There are two fixed pulleys 1051a , and the distance between the two fixed pulleys 1051a is arranged horizontally and perpendicular to the axis of the fixed pulley 1051a .

[0026] The outer sheet 1051b is made of an elastic metal sheet, such as a metal spring sheet, and the outer sheet 1051b includes a circular segment and a vertical segment. Initially, the circular segment is located above the two fixed pulleys 1051a and the axis of the circular segment is parallel to the axis of the fixed pulley 1051a. The central angle of the circular segment is less than three hundred and sixty degrees, so a gap is formed at the lowest point of the outer circular surface. The vertical segment is arranged vertically, and there are two vertical segments, which are respectively arranged at both ends of the gap of the circular segment. The connection between the vertical segment and the circular segment is arc-shaped. The two fixed pulleys 1051a are respectively located on the opposite sides of the two vertical segments, and the two fixed pulleys 1051a are respectively tangent to the two connections.

[0027] It should be noted that although the outer sheet 1051b is divided into a circular segment and a vertical segment, the two are integrally formed and are divided into two segments only for the convenience of description. In addition, when relative displacement occurs between the outer sheet 1051b and the fixed pulley 1051a, for example, with the outer sheet 1051b as a reference, when the two fixed pulleys 1051a move up synchronously, the circular segment will maintain an approximate circular shape, but the inner diameter will gradually decrease. Similarly, when the two fixed pulleys 1051a move down synchronously, the circular segment will be reset, maintaining an approximate circular shape and the inner diameter will gradually increase.

[0028] The bottom of the vertical section is connected to the connecting plate 1051e. Therefore, when the connecting plate 1051e is driven to move downward by the driving component 1052, the vertical section will move downward together, which is equivalent to causing the fixed pulley 1051a to move upward relative to the outer sheet 1051b. Similarly, when the connecting plate 1051e is driven to move upward by the driving component 1052, the outer sheet 1051b is reset due to its own elastic properties.

[0029] An inner airbag 1051c is provided on the inner wall of the outer sheet 1051b, and an air duct 1051d is provided at the end of the inner airbag 1051c. Air can be injected into the inner airbag 1051c through the air duct 1051d to expand the inner airbag 1051c.

[0030] Reference Figure 5 and Figure 6The driving component 1052 includes a pump housing 1052b arranged vertically and arranged on the mounting base 1022. The lower closed end of the pump housing 1052b is provided with an air hole, the upper open end of the pump housing 1052b is provided with a pump cover, the pump cover is provided with an upper nozzle 1052c, the end of the upper nozzle 1052c is provided with a connecting pipe 1052a, air can be injected into the pump housing 1052b through the connecting pipe 1052a, and a piston 1052d is provided in the pump housing 1052b, so that the piston 1052d can be moved downward, and a piston rod is provided at the bottom of the piston 1052d. 1052e, the lower end of the piston rod 1052e extends out of the pump housing 1052b and is connected to the connecting plate 1051e. The outer sleeve of the piston rod 1052e is provided with a second spring 1052f located between the piston 1052d and the lower closed end of the pump housing 1052b. The piston 1052d moves downward with the piston rod 1052e and the connecting plate 1051e, and the second spring 1052f is compressed. When the air injection stops, the second spring 1052f will release the elastic force, causing the piston 1052d, the piston rod 1052e and the connecting plate 1051e to move upward together.

[0031] In the above process, air can be provided to the air pipe 1051d or the connecting pipe 1052a through existing technologies, such as air compressors, air tanks storing compressed air, etc., which will not be described in detail.

[0032] Working principle of embodiment 1: The patient puts the limb through the cuff 1051. Preferably, a pillow 104 can be provided on the side of the mounting seat 1022 away from the supporting seat 102, which can effectively support the patient's limb in conjunction with the supporting seat 102. Then, the driving component 1052 drives the connecting plate 1051e downward, and the connecting plate 1051e moves downward together with the vertical segment of the outer sheet 1051b. This is equivalent to causing the fixed pulley 1051a to move upward relative to the outer sheet 1051b, so that the annular segment maintains an approximately annular shape, but the inner diameter gradually decreases, so that the inner airbag 1051c contacts the patient's limb. Then, air is injected into the inner airbag 1051c through the air tube 1051d, causing the inner airbag 1051c to expand and bind and compress the patient's limbs; After the blood collection is completed, the air in the inner air bag 1051c is discharged through the air duct 1051d, and the driving component 1052 drives the connecting plate 1051e to move upward. At this time, with the outer sheet 1051b as a reference, the fixed pulley 1051a moves downward relatively, and the outer sheet 1051b is reset under the action of its own elastic properties, that is, the strapping assembly 105 is reset, loosening the binding on the patient's limbs.

[0033] It should be noted that the air pipe 1051d or the connecting pipe 1052a is connected to the air compressor, air tank, etc. through a three-way valve. Therefore, air can be injected into the inner air bag 1051c or the pump housing 1052b through the air pipe 1051d or the connecting pipe 1052a, and the air in the inner air bag 1051c or the pump housing 1052b can be discharged through the air pipe 1051d or the connecting pipe 1052a. The three-way valve can be realized by existing technology and will not be elaborated on.

[0034] In a preferred embodiment, after the patient's limbs are bound, the patient's limbs are restricted and cannot move, so there will be a sense of discomfort. Figure 2 A vertically arranged guide rod 1021 is provided on the supporting seat 102, and the guide rod 1021 is slidably connected to the mounting seat 1022. A first spring 1023 is provided on the outer sleeve of the guide rod 1021. Two first springs 1023 are provided and are respectively located on the upper and lower sides of the mounting seat 1022. The advantage is that after the patient's limbs are tied up, the patient's limbs can move slightly, which will not affect the blood collection process, and the patient will be more comfortable.

[0035] Furthermore, a limiting ring is provided on the outside of the guide rod 1021 and is located above the mounting seat 1022 for assembling the first spring 1023 located above.

[0036] From the above description we can see that: 1. This solution can achieve automated binding and compression of the cuff, reducing the workload of blood drawers. On this basis, this solution first places the cuff's inner airbag close to the patient's limb, then injects air into the inner airbag to inflate it, achieving the purpose of binding and compression. The advantage is that it can adapt to patients of different body shapes and has a wider range of uses; It should be noted that those skilled in the art may easily think of realizing automatic binding and compression of the patient's limbs by using a structure similar to that used for binding the arms in blood pressure testing instruments. However, this method has its drawbacks: this method simply relies on the expansion of an air bag to bind the arm. Therefore, in order to achieve an adaptive effect, the rubber skin constituting the air bag has a larger area. Then, when encountering a patient with a thinner arm, the inflated air bag will less block the blood collector's line of sight. However, when encountering a patient with a thicker arm, the distance between the air bag and the patient's arm is smaller. Therefore, after the air bag contacts the arm, the air bag will swell to both sides, blocking both sides of the arm where the arm is bound. In addition, since the compression cuff is generally tied near the blood collection location during blood collection, it is easy to block the blood collector's line of sight. In contrast, this problem does not exist in the present solution. 2. In this solution, the layout of the cuff and the way of driving the cuff to bind and compress the patient's limbs are compared with the technology mentioned in the background technology. On the one hand, during the binding and compression process, no sliding friction will occur between the outer sheet (equivalent to the cuff main body in the background technology) and the inner airbag (equivalent to the airbag in the background technology). Therefore, it can solve the problem that "the movement of the B end of the cuff main body will inevitably generate sliding friction with the airbag, which is easy to cause wear of the airbag. In mild cases, the airbag will be worn thin, affecting the effect of the airbag binding and compressing the patient's limbs. In severe cases, it is easy to cause the airbag to rupture and cannot continue to be used." On the other hand, the patient's limbs will only be in contact with the airbag throughout the whole process, which solves the problem that "the loop is easy to hit the patient, causing discomfort to the patient." Example

[0037] Reference Figure 1 and Figure 2 When drawing blood, since some patients have thin blood vessels and some blood drawers are inexperienced, it is easy for the blood collection needle to have difficulty accurately inserting the blood vessels. In order to solve this problem, an auxiliary component 103 is provided on the support seat 102.

[0038] Specifically, refer to Figure 2 and Figure 7 The auxiliary component 103 includes an upper bracket 1031 located above the supporting seat 102, and a mounting ring 1032 is provided on the upper bracket 1031. The axis of the mounting ring 1032 is arranged vertically, and a magnifying glass 1034 is provided in the mounting ring 1032. The lower end surface of the mounting ring 1032 is provided with a plurality of lamp beads 1033; through the illumination of the lamp beads 1033 and the magnifying function of the magnifying glass 1034, it is convenient for blood collection personnel to accurately insert the blood collection needle into the blood vessel.

[0039] In a preferred embodiment, the upper bracket 1031 and the supporting seat 102 are hingedly connected, and the hinge axis formed at the hinge is arranged vertically (not shown in the figure). The advantage is that for experienced blood collectors, the presence of the auxiliary component 103 may cause interference. Therefore, blood collectors can choose whether to use the auxiliary component 103 according to their own habits.

[0040] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
