Description

Technical Field

[0001] The invention relates to the technical field of medical care appliances, and in particular to a device for automatically memorizing the rotation rule of peripheral blood collection sites. Background Art

[0002] Diabetes is a chronic, lifelong disease. The 2017 edition of the "Guidelines for the Prevention and Treatment of Type 2 Diabetes in China" published by the Diabetes Branch of the Chinese Medical Association points out that blood glucose monitoring is an important part of diabetes management. Its results help to assess the degree of glucose metabolism disorder in diabetic patients, formulate reasonable glucose-lowering plans, reflect the effect of glucose-lowering treatment and guide the adjustment of treatment plans. Good blood glucose control is the basis for the management of diabetic patients, and blood glucose monitoring is a key link in diabetes management. As a necessary monitoring method, blood glucose monitoring can help doctors formulate glucose-lowering plans, predict hypoglycemia, especially the overall changes in blood glucose in patients, and become a reliable indicator for clinical assessment of blood glucose control levels and accurate medication by doctors. Therefore, once each diabetic patient is diagnosed, the nursing staff should promptly give the patient diabetes education and recommend that the patient conduct blood glucose monitoring. The standard time for blood glucose monitoring is before three meals, 2 hours after three meals, and 22:00; those with obvious blood glucose fluctuations need to increase blood glucose testing at 2:00. The specific monitoring frequency should be determined according to the actual needs of the patient.

[0003] At present, hospitals mostly provide health guidance to diabetic patients through various educational methods, and recommend that patients adhere to self-blood sugar monitoring after discharge. However, most patients can buy home blood glucose meters, but they do not monitor their blood sugar themselves. Due to the high frequency of blood sugar monitoring every day and the lack of rotation and positioning teaching aids, blood will be drawn from the same finger repeatedly in a day; or the positioning of the blood collection teaching aids is unclear, and adjacent blood collection points cannot be accurately spaced; or the teaching content that the hospital needs to remember orally can be unclear, which can increase the pain during needle pricking and even cause finger infection and scars, causing patients to resist, affecting the treatment effect of the disease, and is not conducive to blood sugar control. Therefore, it is extremely important to provide diabetic patients with a device that can automatically remember and reasonably rotate the blood collection sites. Summary of the invention

[0004] In view of the above technical problems, the present invention discloses a device for automatically memorizing the rotation rules of peripheral blood collection sites, which replaces the previous education in the form of vague positioning, high blood collection point cycle frequency, and oral memory. It is to solve the problem that diabetic patients frequently monitor their blood sugar every day, but cannot accurately remember the rotation rules of blood collection sites. Repeated blood collection at the same site or adjacent sites causes pain during needle pricking, psychological resistance, and even finger infection and scarring, which directly affects the compliance of blood sugar monitoring and affects hypoglycemic treatment. The technical solution adopted by the present invention is:

[0005] A device for automatically memorizing the rotation rules of peripheral blood collection sites, comprising a box body, on which a first window and a second window are provided. The first window can sequentially display marks representing fingers that can be rotated for peripheral blood collection, and the second window can sequentially display the mark of each finger blood collection point. When all the finger marks displayed in the first window are rotated, the mark in the second window is only changed once.

[0006] Furthermore, there are a total of 8 fingers that can be used for rotating peripheral blood sampling, namely the left index finger, right index finger, left middle finger, right middle finger, left ring finger, right ring finger, left little finger, and right little finger, respectively abbreviated as left index, right index, left middle, right middle, left no, right no, left little finger, and right little finger; each finger blood sampling point has a total of N labels, namely 1, 2, 3, ...N.

[0007] Furthermore, axis 1 and axis 2 are pivotally provided on the left and right walls of the box body, and an octagonal prism is fixedly provided on the axis 1, and the eight side surfaces of the octagonal prism are respectively and sequentially marked as: left eccentric, right eccentric, left middle, right middle, left non-existent, right non-existent, left small, and right small; an N-shaped prism is fixedly provided on the axis 2, and the N side surfaces of the N-shaped prism are respectively and sequentially marked as 1, 2, 3, ... N; it also includes a sheave mechanism, in which one end surface of the octagonal prism also serves as a dial of the sheave mechanism, on which a convex locking arc and a cylindrical pin are fixedly provided; the sheave of the sheave mechanism is fixedly provided on the axis 2, and the sheave has N radial grooves and N concave locking arcs.

[0008] Furthermore, an operating wheel is fixed on the axis outside the box body, and a calibration mark is provided on the operating wheel. A circle of calibration positioning grids is arranged on the box body around the operating wheel. The calibration positioning grids take the central axis of the operating wheel as the center point and are spaced 45° apart. Each of the calibration positioning grids corresponds to the middle point of the eight sides of the regular octagonal prism.

[0009] Furthermore, a ratchet gear is fixedly arranged on the shaft 1, and the number of teeth of the ratchet gear is an integral multiple of 8, corresponding to each side surface of the octagonal prism; a ratchet shaft is fixedly arranged on the box body, and a ratchet is hinged on the ratchet shaft, and the ratchet is in abutment with the ratchet gear.

[0010] Furthermore, a torsion spring is wound around the pawl shaft, one end of the torsion spring abuts against the pawl, and the other end abuts against the box body.

[0011] Furthermore, a patient information card slot is provided on the outer side of the box body for storing the patient information card.

[0012] Furthermore, a schematic diagram of N blood collection points on fingers is also provided on the outer side of the box body, wherein the odd-numbered points are on the left and the even-numbered points are on the right.

[0013] Compared with the prior art, the present invention can effectively reduce the patient's skin damage, infection rate, and pain, and improve the patient's self-blood sugar monitoring and self-management, ultimately achieving the purpose of controlling blood sugar. Before each blood sugar test, the patient does not need to remember or recall any rotation rules, but only needs to turn the operating wheel to align the calibration mark with the calibration grid, and the window automatically displays the blood sampling point to be rotated. The blood sampling point has a low rotation frequency, sufficient healing time, and accurate positioning, which effectively avoids repeated blood sampling on the same finger within a day.

[0023] Embodiment 1, as Figure 1-5 The device shown in the figure automatically memorizes the rotation rule of peripheral blood collection sites, comprises a box body 10, a window 101 and a window 202 are provided on the box body 10, a shaft 10 and a shaft 20 are pivotally arranged on the left and right walls of the box body 10, a regular octagonal prism 40 is fixedly arranged on the shaft 10, and the eight sides of the regular octagonal prism 40 are marked in sequence: left food, right food, left middle, right middle, left none, right none, left small, right small; a regular hexagonal prism 50 is fixedly arranged on the shaft 20 of this embodiment. , the six sides of the regular hexagonal prism 50 are marked 1, 2, 3, 4, 5, and 6 in sequence; this embodiment also includes a sheave mechanism, wherein one end face of the regular octagonal prism 40 also serves as a dial of the sheave mechanism, on which a convex locking arc 60 and a cylindrical pin 70 are fixed; the sheave 80 of the sheave mechanism is fixed on the shaft 2 30, and the sheave 80 has 6 radial grooves 801 and 6 concave locking arcs 802; an operating wheel 90 is fixed on the shaft 1 20 outside the box body 10. The operating wheel has a calibration mark 901, and a circle of calibration locators 150 is set on the box body around the operating wheel. The calibration locators 150 are 45° apart with the central axis of the operating wheel as the circle point, and each calibration locator corresponds to the middle point of the eight sides of the regular octagonal prism 40. A schematic diagram 130 of six blood collection points of fingers is also provided on the outer side of the box body, wherein the odd points are on the left and the even points are on the right.

[0024] The left index finger, right index finger, left middle finger, right middle finger, left non-index finger, right non-index finger, left little finger, and right little finger marked on the eight sides of the regular octagonal prism 40 represent the left index finger, right index finger, left middle finger, right middle finger, left ring finger, right ring finger, left little finger, and right little finger respectively; the 1, 2, 3, 4, 5, and 6 marked on the six sides of the regular hexagonal prism 50 represent the six blood collection points of each finger respectively, such as Figure 3In the schematic diagram 130, the odd points are on the left and the even points are on the right. When monitoring blood sugar, in order to ensure accurate positioning, the patient can compare the finger to be tested with the schematic diagram 130 to assist in positioning. The label is marked with 6 blood sampling point numbers. In order to avoid overlap of two adjacent blood sampling points due to deviation and to ensure that the blood sampling points have sufficient time to heal after blood sampling, the 6 points are divided into odd columns and even columns. Each blood sampling point is 0.2 cm apart, and each blood sampling point is a circle with a diameter of 0.2 cm. This can ensure a one-way cycle of 48 blood sampling points, reasonable use, and non-repetitive positions.

[0025] When in use, the operating wheel 90 is rotated to align the calibration mark 901 with the calibration positioning grid 150, so that the window 1 101 can sequentially display the marks representing the fingers that can be rotated for peripheral blood sampling, and the window 2 102 can sequentially display the mark of each finger blood sampling point. When all the finger marks displayed in the window 1 101 are rotated, the mark in the window 2 102 is only changed once.

[0026] Since the present embodiment adopts a sheave mechanism with six radial grooves 801, when the shaft 1 rotates one circle, the shaft 2 rotates only one sixth of a circle. That is, when the shaft 1 rotates one circle, eight different logos will be displayed in the window 101, while the logo in the window 2 102 will not change. Figure 3 As shown, window one 101 switches from left index finger, right index finger, left middle finger, right middle finger, left none, right none, left little finger to right little finger, and the mark of window two 102 is always "1", which means that the patient has blood drawn from blood collection point No. 1 of the left index finger, right index finger, left middle finger, right middle finger, left ring finger, right ring finger, left little finger, and right little finger in sequence; when "left index finger" is displayed again in window one 101, the mark of window two 102 will be "2", which means that the patient has blood drawn from blood collection point No. 2 of the left index finger, right index finger, left middle finger, right middle finger, left ring finger, right ring finger, left little finger, and right little finger in sequence; and so on, which can avoid repeated blood drawing at 48 blood drawing points and ensure that the blood drawing points have sufficient time to heal.

[0027] Embodiment 2 is the same as Embodiment 1 except that a ratchet gear 100 is fixedly arranged on the shaft 1 20, and the number of teeth of the ratchet gear 100 is 8, corresponding to each side of the octagonal prism; a ratchet shaft 120 is fixedly arranged on the box body 10, and a ratchet 110 is hinged on the ratchet shaft 120, and the ratchet 110 is in abutment with the ratchet gear 100, and a torsion spring is wound around the ratchet shaft 120, and one end of the torsion spring is in abutment with the ratchet 110, and the other end is in abutment with the box body 10. A patient information card slot 140 is also arranged on the outer left side of the box body for storing the patient information card.

[0028] A one-way ratchet mechanism is used to ensure the one-way rotation of the operating wheel, preventing the two-way rotation from causing a disorder in the rotation pattern of the blood collection sites.

[0029] A slot for patient information cards is provided to prevent mixing between patients during hospitalization, which would cause confusion in the rotation pattern of blood collection points.

[0030] The present invention can not only effectively alleviate the patient's skin damage, reduce the infection rate, and reduce the pain, but also improve the patient's self-blood sugar monitoring and self-management, ultimately achieving the purpose of controlling blood sugar.

[0031] The present invention is simple and easy to operate. The device can automatically memorize the rotation rules of the peripheral blood collection sites, and there is a positioning device to improve the positioning accuracy. It is simple to operate, intuitive, and low-cost, and is more suitable for patients who are busy with daily work or are old and have poor memory. It can effectively avoid repeated blood sampling at the blood collection point in a short period of time. The present invention solves the troubles of patients who need to monitor blood sugar for a long time. There is no need to remember the rotation rules of the peripheral blood collection sites and the positioning is accurate. It can effectively avoid local skin damage and infection at the blood collection site, reduce pain, and improve the patient's compliance with blood sugar measurement, so as to achieve the purpose of controlling blood sugar, reduce and reduce the occurrence of complications, and improve the patient's quality of life.

[0032] The above-mentioned embodiments are only descriptions of the preferred implementation methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made by ordinary technicians in the field to the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention. For example, the grooved wheel mechanism can also be replaced by an incomplete gear mechanism and other intermittent mechanisms in the intermittent mechanism, and the number of marks for each finger blood sampling point is not six but other numbers. Correspondingly, the fixed connection with the second axis is not a regular hexagonal prism but a regular prism with a corresponding number of sides.
