Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical device blood sampling and pulse machine. Background Art

[0002] As modern people pay more and more attention to their own health, most people will have a physical examination once or twice a year. Physical examination is inseparable from blood drawing, blood pressure measurement and pulse counting. The existing blood drawing methods mostly use the traditional manual compression cuff method, which uses the cuff to compress the vein to expose the vein to complete the blood drawing process. Usually, one examinee is assigned one medical staff, which greatly increases the workload of medical staff during group physical examinations. As patients now have higher and higher requirements for the medical environment, the repeated use of cuffs and pads is prone to skin cross-infection medical accidents. Blood pressure measurement and pulse counting are also a basic part of the physical examination, and medical staff are also required to be on duty. The process is relatively complicated, which wastes the time of the examinee and greatly increases the work pressure of the medical staff.

[0003] In the prior art, a Chinese invention patent with publication number CN110403616A discloses a blood sampling pulse meter. The blood sampling pulse meter includes a controller and a blood sampling pulse meter body, the blood sampling pulse meter body includes a fixed shell and a rotating shell, the middle of the fixed shell and the rotating shell are both provided with grooves, when the lower end of the rotating shell contacts the upper end of the fixed shell, the two groups of the grooves form a through hole; air bags are provided in the two groups of the grooves, the blood sampling pulse meter body is provided with an inflation mechanism, the air outlet of the inflation mechanism is connected to the inflation port of the air bag, and the input end of the inflation mechanism is electrically connected to the output end of the controller; the blood sampling pulse meter can simultaneously complete blood pressure measurement, pulse counting and blood drawing, reducing the use of the site and reducing the workload of medical staff.

[0004] The above device drives the non-woven fabric to rewind through a stepper motor, so that when the patient uses the device, the non-woven fabric can be replaced, and the patient's arm and the airbag are isolated by the non-woven fabric to prevent cross infection. However, when the patient places his arm, there may be a certain deviation (for example, children are more likely to move when having blood drawn), and when the airbag is not fully inflated, the patient's arm may move, which may cause the non-woven fabric to wrinkle or entangle. When the non-woven fabric is wrinkled or entangled, it can no longer isolate the patient's arm from the airbag, thus causing cross infection. Summary of the invention

[0005] The embodiment of the present application provides a medical blood sampling device, which solves the technical problem in the prior art that if the patient's arm moves when placing the arm, the non-woven fabric may be entangled or wrinkled, thereby affecting the isolation effect of the non-woven fabric.

[0006] An embodiment of the present application provides a medical device for collecting blood and pulse, comprising a base, a fixed shell and a rotating shell, wherein the fixed shell is fixedly mounted on the top of the base, and the rotating shell is rotatably mounted on the top of the fixed shell, and a placement groove is provided on the side where the rotating shell and the fixed shell are close to each other, and a circular placement through hole can be formed when the two placement grooves are in contact, and an airbag is installed in each placement groove, and the airbag is semi-annular, and an air pump capable of controlling the expansion of the airbag is installed in the fixed shell, and a blood pressure measurement sensor and a pulse counting sensor are installed in the airbag, and a blood drawing hand rest is also fixedly mounted on the base, and a rotating shaft is installed in both the fixed shell and the rotating shell, and a non-woven fabric is wound on the rotating shaft in the rotating shell, and the other end of the non-woven fabric is connected to the rotating shaft in the fixed shell, and strip capsules are bonded and fixed to both ends of the non-woven fabric on one side facing the airbag, and the strip capsules can provide support for the non-woven fabric.

[0007] Furthermore, the width of the non-woven fabric is greater than the width of the airbag, and the spacing between the strip-shaped bags on both sides of the non-woven fabric is greater than the width of the airbag.

[0008] Furthermore, the strip-shaped capsule is filled with magnetic fluid, and a plurality of magnetic sheets are fixed on the front and rear sides of each of the airbags, and the magnetic sheets can generate magnetic attraction with the magnetic fluid in the strip-shaped capsule.

[0009] Furthermore, there are several strip-shaped bags on each side of the non-woven fabric, and the several strip-shaped bags are bonded to the non-woven fabric and connected to each other by drawstrings. When the non-woven fabric contacts the airbag, the non-woven fabric can be adsorbed on the airbag through the magnetic attraction of the magnetic sheet and the magnetic fluid in the strip-shaped bags, and the gaps between the several strip-shaped bags can provide deformation space for the non-woven fabric to fit the semi-circular airbag.

[0010] Furthermore, the several strip capsules on each side of the non-woven fabric are divided into long strip capsules and short strip capsules, the length of the long strip capsules is greater than the length of the short strip capsules, and the several long strip capsules and the several short strip capsules are arranged alternately on the non-woven fabric, and the several long strip capsules and the several short strip capsules on the same side of the non-woven fabric are connected to each other by drawstrings.

[0011] Furthermore, one end of the rotating shell is rotatably connected to the fixed shell, and a sector gear is installed at one end of the rotating shell and the fixed shell. A motor frame is fixed in the fixed shell, and a driving motor is installed on the motor frame. The main shaft of the driving motor passes through the motor frame and is connected to the driving gear, and the driving gear is meshed with the sector gear.

[0012] Furthermore, a stepper motor is fixedly installed in the fixed shell, and the output shaft of the stepper motor and the outer surface of the rotating shaft in the fixed shell are fixedly connected with pulleys, a synchronous belt is arranged between the two sets of pulleys, and a synchronous cover capable of protecting the pulleys and the synchronous belt is also installed on the outside of the fixed shell.

[0013] Furthermore, a tensioning column for providing tensioning force to the non-woven fabric is rotatably installed in the fixed shell.

[0014] Furthermore, a matching groove which fits with the strip bag is provided on the tensioning column.

[0015] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: First, the present invention can significantly reduce the wrinkles or entanglement problems of the non-woven fabric when the patient's arm is placed offset or moved through the supporting effect of the strip bag, thereby ensuring that the non-woven fabric can always effectively isolate the patient's arm from the airbag, and due to the supporting effect of the strip bag, it can ensure that the non-woven fabric always remains flat, thereby avoiding the influence of wrinkles or entanglement on blood pressure measurement and pulse counting, and improving the accuracy of measurement; by reducing the wrinkles and entanglement problems of the non-woven fabric, the risk of wear and tear caused by the non-woven fabric getting stuck on other parts when the stepper motor is working to rewind the non-woven fabric can be reduced, and the workload of operators who frequently change or arrange the non-woven fabric can be reduced; Second, the present invention uses the magnetic attraction of magnetic fluid and magnetic sheet to make the non-woven fabric fit tightly on the airbag, and will not fall off or shift easily even if the patient's arm moves, thereby improving the stability and reliability of the equipment and ensuring that the non-woven fabric can achieve its isolation effect to prevent cross infection; Third, the present invention arranges multiple strip capsules on the non-woven fabric at intervals and designs the gaps between the strip capsules, so that the non-woven fabric can better adapt to the shape and size of the airbag, ensuring the close fit between the non-woven fabric and the airbag, thereby improving the isolation effect. The magnetic attraction between the magnetic fluid in the strip capsule and the magnetic sheet on the airbag enables the non-woven fabric to fit firmly on the airbag. Even if the patient's arm moves, the non-woven fabric will not fall off or shift easily, thereby enhancing the stability of the device; Fourthly, the present invention arranges the long strip capsules and the short strip capsules in a staggered manner. On the premise that the non-woven fabric can adapt to and fit the semi-circular airbag, the long strip capsules maintain the supporting effect on the non-woven fabric, so that the non-woven fabric is not easily deformed before and after fitting with the airbag, and can better isolate the patient's arm from the airbag to prevent cross infection.

[0021] Embodiment 1: Figure 1-Figure 4As shown, the embodiment of the present application provides a medical device blood sampling pulse machine, including a base 100, a fixed shell 110 and a rotating shell 120, wherein the fixed shell 110 is fixedly mounted on the top of the base 100, and the rotating shell 120 is rotatably mounted on the top of the fixed shell 110, and a placement groove 130 is provided on the side where the rotating shell 120 and the fixed shell 110 are close to each other, and the two placement grooves 130 can form a circular placement through hole when they are in contact, and an air bag 140 is installed in each placement groove 130, and the air bag 140 is semi-circular, and the fixed shell 110 is fixedly mounted on the top of the fixed shell 110, and the rotating shell 120 is rotatably mounted on the top of the fixed shell 110, and the rotating shell 120 and the fixed shell 110 are close to each other. An air pump (not shown in the figure) capable of controlling the expansion of the airbag 140 is installed inside the airbag 140, a blood pressure measurement sensor and a pulse counting sensor (not shown in the figure) are installed inside the airbag 140, a blood drawing hand pillow 150 is also fixedly installed on the base 100, a rotating shaft 160 is installed in both the fixed shell 110 and the rotating shell 120, a non-woven fabric 200 is wound on the rotating shaft 160 in the rotating shell 120, the other end of the non-woven fabric 200 is connected to the rotating shaft 160 in the fixed shell 110, and the two ends of the non-woven fabric 200 facing one side of the airbag 140 The strip capsule 210 is bonded and fixed, and the strip capsule 210 can provide support for the non-woven fabric 200. A controller is also installed on the base 100. The output ends of the blood pressure measurement sensor and the pulse counting sensor are electrically connected to the input end of the controller. When performing blood sampling, the operator controls the rotating shell 120 to rotate so that the moving end of the rotating shell 120 rotates upward, and a gap appears between the rotating shell 120 and the fixed shell 110, and the non-woven fabric 200 is exposed in the gap. At this time, the patient places his arm through the gap on the fixed shell 110. The non-woven fabric 200 is placed on the placement groove 130, and will be driven to fit into the placement groove 130. Then the operator controls the rotating shell 120 to reset and drives the airbag 140 to expand. At this time, the patient's forearm is placed on the blood drawing hand pillow 150, and the operator can perform the blood drawing operation. At the same time, the blood pressure measurement sensor and the pulse counting sensor work to measure the patient's blood pressure and pulse. After the blood drawing is completed, the above steps are repeated to make the patient draw out his arm, and then the rotating shaft 160 in the fixed shell 110 is driven to rotate to roll up the used non-woven fabric 200.

[0022] The side ends of the fixed shell 110 and the rotating shell 120 are both detachably mounted with mounting shells, and the non-woven fabric 200 in the rotating shell 120 and the fixed shell 110 can be replaced by opening the mounting shells.

[0023] Preferably, one end of the rotating shell 120 is rotatably connected to the fixed shell 110, and a sector gear 111 is installed at one end of the rotating shell 120 rotatably connected to the fixed shell 110, and a motor frame 112 is fixed in the fixed shell 110, and a driving motor 113 is installed on the motor frame 112. The main shaft of the driving motor 113 passes through the motor frame 112 and is connected to a driving gear 114. The driving gear 114 is meshed with the sector gear 111, and the driving motor 113 is electrically connected to the controller. When the driving motor 113 is working, the rotating shell 120 is driven to rotate by the meshing driving gear 114 and the sector gear 111. This is a prior art and will not be elaborated on.

[0024] Preferably, a stepper motor 161 is also fixedly installed in the fixed shell 110, and the output shaft of the stepper motor 161 and the outer surface of the rotating shaft 160 in the fixed shell 110 are fixedly connected with a pulley 162, and a synchronous belt 163 is arranged between the two sets of pulleys 162. A synchronous cover 164 capable of protecting the pulleys 162 and the synchronous belt 163 is also installed on the outer side of the fixed shell 110. The stepper motor 161 is electrically connected to the controller. When the stepper motor 161 is working, the rotating shaft 160 in the fixed shell 110 is driven to rotate through the two sets of pulleys 162 and the synchronous belt 163, and then the non-woven fabric 200 is rolled up to achieve the replacement of the non-woven fabric 200. This is a prior art and will not be elaborated in detail.

[0025] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: Through the support of the strip bag 210, the wrinkle or entanglement problem of the non-woven fabric 200 when the patient's arm is placed offset or moved can be significantly reduced, thereby ensuring that the non-woven fabric 200 can always effectively isolate the patient's arm from the airbag 140, and due to the support of the strip bag 210, it can be ensured that the non-woven fabric 200 always remains in a flat state, thereby avoiding the influence of wrinkles or entanglement on blood pressure measurement and pulse counting, and improving the accuracy of measurement; by reducing the wrinkle and entanglement problems of the non-woven fabric 200, the risk of wear and tear caused by the non-woven fabric 200 getting stuck on other parts when the stepper motor 161 is working to rewind the non-woven fabric 200 can be reduced, thereby reducing the workload of operators who frequently replace or arrange the non-woven fabric 200.

[0026] Embodiment 2: In order to further ensure the isolation effect of the non-woven fabric 200 on the patient's arm and the airbag 140, as shown in FIG. Figure 5 As shown, further improvements are made to the first embodiment: Preferably, the width of the non-woven fabric 200 is greater than the width of the airbag 140 , and the distance between the strip-shaped bags 210 on both sides of the non-woven fabric 200 is greater than the width of the airbag 140 .

[0027] Preferably, the strip-shaped capsule 210 is filled with magnetic fluid, and a plurality of magnetic sheets 220 are fixed to the front and rear sides of each of the airbags 140 . The magnetic sheets 220 can generate magnetic attraction with the magnetic fluid in the strip-shaped capsule 210 .

[0028] When the patient places his arm, the non-woven fabric 200 will be driven to move toward the airbag 140. When the non-woven fabric 200 contacts the airbag 140, the strip bag 210 on the non-woven fabric 200 generates a magnetic attraction force with the magnetic sheet 220 on the airbag 140 through the magnetic fluid filled inside, thereby providing a certain fixing effect for the contact between the non-woven fabric 200 and the airbag 140. When the non-woven fabric 200 is rolled up, the magnetic attraction force will not affect the rolling up of the non-woven fabric 200. Moreover, since the width of the non-woven fabric 200 and the spacing between the strip bags 210 are both greater than the width of the airbag 140, and the magnetic sheet 220 is located on the front and rear sides of the airbag 140, the detection effect of the blood pressure measurement sensor and the pulse counting sensor in the airbag 140 will not be affected after the strip bag 210 and the magnetic sheet 220 are magnetically attracted.

[0029] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: Through the magnetic attraction of the magnetic fluid and the magnetic sheet 220, the non-woven fabric 200 can fit tightly on the airbag 140 and will not easily fall off or shift even if the patient's arm moves, thereby improving the stability and reliability of the equipment and ensuring that the non-woven fabric 200 can achieve its isolation effect and prevent cross infection.

[0030] Embodiment 3: Since the airbag 140 is semi-circular, after the strip bag 210 is installed on the non-woven fabric 200, the strip bag 210 on the non-woven fabric 200 may not be able to adapt to and fit the semi-circular airbag 140 (since the strip bag 210 has a certain elasticity, after the strip bag 210 is fitted with the semi-circular airbag 140, the elasticity of the strip bag 210 itself will interact with the magnetic attraction of the magnetic sheet 220 and the magnetic fluid, thereby affecting the isolation effect of the non-woven fabric 200). In order to avoid the above situation, Figure 6 As shown, further improvements are made to the second embodiment: Preferably, there are several strip capsules 210 on each side of the non-woven fabric 200, and the several strip capsules 210 are bonded to the non-woven fabric 200, and the several strip capsules 210 are connected to each other by drawstrings 230. Since the strip capsules 210 on the non-woven fabric 200 are fixed to the non-woven fabric 200 by bonding, the strip capsules 210 are connected by drawstrings 230, which simplifies the strength of the initial assembly operation. When the non-woven fabric 200 contacts the airbag 140, the non-woven fabric 200 can be adsorbed on the airbag 140 through the magnetic attraction of the magnetic sheet 220 and the magnetic fluid in the strip capsules 210, and the gaps between the several strip capsules 210 can provide deformation space for the non-woven fabric 200 to fit the semi-circular airbag 140.

[0031] Preferably, a tensioning column 240 for providing tensioning force to the non-woven fabric 200 is rotatably installed in the fixed shell 110 .

[0032] Preferably, the tensioning column 240 is provided with a matching groove that fits with the strip bag 210. The matching groove can accommodate the strip bag 210 and can limit the strip bag 210, further ensuring that the non-woven fabric 200 is not easily deformed, and can stably isolate the patient's arm from the airbag 140 to prevent cross infection.

[0033] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: By arranging multiple strip-shaped capsules 210 at intervals on the non-woven fabric 200 and designing the gaps between the strip-shaped capsules 210, the non-woven fabric 200 can better adapt to the shape and size of the airbag 140, ensuring the close fit between the non-woven fabric 200 and the airbag 140, thereby improving the isolation effect, and the magnetic attraction between the magnetic fluid in the strip-shaped capsules 210 and the magnetic sheet 220 on the airbag 140 enables the non-woven fabric 200 to be firmly attached to the airbag 140. Even if the patient's arm moves, the non-woven fabric 200 will not fall off or shift easily, thereby enhancing the stability of the device.

[0034] Embodiment 4: In the above solution, a plurality of strip-shaped capsules 210 are provided, which may affect the supporting effect of the strip-shaped capsules 210 on the non-woven fabric 200. In order to solve this problem, Figure 7 As shown, further improvements are made to the third embodiment: Preferably, the several strip-shaped capsules 210 on each side of the non-woven fabric 200 are divided into long strip capsules 211 and short strip capsules 212, the length of the long strip capsules 211 is greater than the length of the short strip capsules 212, and the several long strip capsules 211 and the several short strip capsules 212 are arranged alternately on the non-woven fabric 200, and the several long strip capsules 211 and the several short strip capsules 212 on the same side of the non-woven fabric 200 are connected to each other by a drawstring 230.

[0035] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: By staggered arrangement of the long strip capsules 211 and the short strip capsules 212, while the non-woven fabric 200 is able to adapt to fit the semi-circular airbag 140, the long strip capsules 211 maintain the supporting effect of the non-woven fabric 200, so that the non-woven fabric 200 is not easily deformed before and after fitting with the airbag 140, and can better isolate the patient's arm from the airbag 140 to prevent cross infection.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
