Through the coordination of mechanical transmission and electrical control, they achieve quantitative collection and sealed storage of blood samples, serving as a tool connecting on-site sampling and laboratory testing.

[0003] In medical rescue or field research, portable blood sample storage devices can quickly draw blood samples using the principle of negative pressure, avoiding contamination or measurement errors caused by manual operation; the storage cylinder and sealing structure can prevent blood sample leakage or deterioration, ensuring sample integrity; the portable design allows it to be used in environments without fixed medical facilities, shortening the time interval between sampling and testing.

[0004] Existing portable blood sample storage devices use a manually operated piston to create negative pressure to draw blood samples, avoiding contamination caused by direct contact with the blood sample and meeting basic sampling requirements to some extent. However, the blood volume of existing devices needs to be adjusted by manually observing the scale and manually controlling the piston stroke. During operation, the scale needs to be checked repeatedly, and inaccurate measurements can easily occur due to hand tremors. Improper operation can easily lead to leakage. It is difficult to meet the needs of rapid, accurate, and continuous sampling in outdoor or emergency rescue scenarios. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable blood sample storage device, which aims to improve the existing technology that relies on manual observation of the scale and manual control of the piston stroke for adjustment. This is prone to inaccurate measurement due to hand tremors and is difficult to meet the needs of rapid, accurate and continuous sampling in outdoor or emergency rescue scenarios.

[0013] As a further description of the above technical solution: The outer surface of the handle is ergonomically designed and has a frosted finish.

[0014] This utility model has the following beneficial effects: 1. In this utility model, pressing the button controls the number of rotations of the drive motor, which in turn drives the drive screw to rotate, causing the rubber piston to move axially along the guide assembly to create negative pressure. Blood samples are then drawn from the conical nozzle through the liquid storage cylinder. Pressing and holding the button triggers a reverse operation to close the liquid storage cylinder, thus achieving quantitative automatic blood sample collection. The amount of blood collected can be precisely controlled by the number of button presses. The operation is simple, and the energy storage mechanism enhances portability. It is suitable for outdoor or emergency rescue scenarios, ensuring the stability and accuracy of blood sample collection.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Reference Figures 2-5 An embodiment of this utility model provides a portable blood sample storage device, including an outer shell 1, a handle 2 fixedly connected to the top of the outer side of the outer shell 1, a conical suction nozzle 3 provided at the bottom of the outer shell 1, a sampling mechanism 4 provided inside the outer shell 1, the sampling mechanism 4 being used to draw blood samples by negative pressure, and an energy storage mechanism 5 provided on the outer side of the outer shell 1, the energy storage mechanism 5 being used to store electrical energy, making the device easy to carry. The sampling mechanism 4 includes a drive motor 41 and a rubber piston 44. The drive motor 41 is fixedly connected to the top of the inner side of the outer cylinder shell 1. A button 42 is fixedly connected to the top of the handle 2, and the button 42 is electrically connected to the drive motor 41. A drive screw 43 is fixedly connected to the bottom of the drive motor 41, and the drive screw 43 is threaded into the inside of the rubber piston 44. A liquid storage cylinder 45 is fixedly connected to the top of the conical suction nozzle 3. A pressure regulating hole 46 is opened at the top of the liquid storage cylinder 45. A guide assembly 47 is provided on the inner side of the outer cylinder shell 1. The guide assembly 47 includes multiple guide posts 471, which are fixedly connected to the inner periphery of the outer cylinder shell 1. Multiple guide grooves 472 are provided on the outer side of the rubber piston 44. A stabilizing assembly 48 is provided on the top of the outer side of the drive screw 43. The stabilizing assembly 48 includes an I-shaped post 481, which is fixedly connected to the upper middle part of the outer side of the drive screw 43. An mounting part 482 is fixedly connected to the upper middle part of the inner side of the outer cylinder shell 1. The interior of the mounting part 482 is rotatably connected to the exterior of the I-shaped post 481. Specifically, in the sampling mechanism 4, the drive motor 41 is fixed to the top of the inner side of the outer cylinder shell 1, and the drive screw 43 at its bottom end is threadedly connected to the rubber piston 44; the button 42 at the top of the handle 2 is electrically connected to the drive motor 41, and pressing the button 42 a different number of times can trigger the drive motor 41 to rotate a different number of times; when the button 42 is pressed, the drive motor 41 is energized and runs, driving the drive screw 43 to rotate; under the action of the threaded engagement, the rubber piston 44 moves axially along the inside of the outer cylinder shell 1, and the guide posts 471 around the inner side of the outer cylinder shell 1 are embedded in the guide grooves 472 on the outside of the rubber piston 44, restricting the rubber piston 44 to rotate synchronously with the drive screw 43, ensuring that it only makes linear motion; The number of rotations of the drive motor 41 directly determines the rotation angle of the drive screw 43, thereby changing the moving height of the rubber piston 44. When the rubber piston 44 moves upward, the volume of the space below the rubber piston 44 inside the outer cylinder shell 1 changes with the moving height, and the air pressure decreases accordingly, forming negative pressure of different degrees. This negative pressure is transmitted to the conical suction nozzle 3 at the bottom through the liquid storage cylinder 45, so that when the conical suction nozzle 3 contacts the blood sample, the amount of blood sample sucked into the liquid storage cylinder 45 varies with the difference in negative pressure intensity. The pressure regulating hole 46 at the top of the liquid storage cylinder 45 can balance the air pressure inside the liquid storage cylinder 45 and the outer cylinder shell 1, avoiding the impact of local air pressure fluctuations on the stability of blood sample aspiration. The I-shaped column 481 on the upper outer side of the drive screw 43 is rotatably connected to the mounting part 482 on the upper inner side of the outer cylinder shell 1. When the I-shaped column 481 rotates with the drive screw 43, the mounting part 482 provides radial support to it, preventing the drive screw 43 from radially shifting or shaking under different rotations, and ensuring that the threaded fit between the drive screw 43 and the rubber piston 44 is always stable. The energy storage mechanism 5 provides power to the drive motor 41, freeing the device from the limitation of external power supply. Together with the handle 2 on the top of the outer shell 1, it is convenient for operators to carry the device to different scenarios. After the blood sample is collected, press and hold the button 42 for three seconds. The drive motor 41 receives the reverse rotation signal, which drives the drive screw 43 to rotate in the opposite direction. The rubber piston 44 moves downward, compressing the space above the liquid storage cylinder 45 and helping to seal the liquid storage cylinder 45 to prevent blood sample leakage. The guide post 471 of the guide assembly 47 cooperates with the guide groove 472 to ensure the straightness of the trajectory of the rubber piston 44 at different moving heights and avoid friction or jamming between it and the inner wall of the outer cylinder shell 1; the I-shaped post 481 of the stabilizing assembly 48 cooperates with the mounting part 482 to enhance the stability of the drive screw 43 under forward and reverse rotation and different rotation numbers, and reduce the impact of mechanical vibration on the accuracy of blood sample quantitative aspiration. The sampling mechanism 4 achieves quantitative automatic blood sample aspiration by controlling the number of times the button 42 is pressed. Pressing the button 42 for a long time triggers a reverse operation to complete the sealing. The liquid storage cylinder 45 stores the blood sample, ensuring a stable and efficient process under different aspiration volumes. The energy storage mechanism 5 and the handle 2 enhance the portability of the device, making the entire device suitable for outdoor sampling or emergency rescue scenarios to meet the collection needs of different blood sample volumes.

[0019] Reference Figure 1 , Figure 6 and Figure 7The energy storage mechanism 5 includes a flame-retardant shell 51, which is fixedly connected to the upper right side of the outer shell 1. The handle 2 is sleeved on the outside of the flame-retardant shell 51. An energy storage power supply 52 is fixedly connected to the top inner side of the flame-retardant shell 51, and a backup power supply 53 is fixedly connected to the bottom inner side of the flame-retardant shell 51. A Type-C charging port 54 is provided at the top right side of the handle 2, and multiple power indicator lights 55 are fixedly connected to the upper right side of the handle 2. Specifically, the flame-retardant shell 51 of the energy storage mechanism 5 is fixed to the upper right side of the outer shell 1, forming a closed space inside. The handle 2 is sleeved on the outside of the flame-retardant shell 51, which is convenient for holding the device and also provides external protection for the flame-retardant shell 51. The energy storage power supply 52 at the top of the inner side of the flame-retardant shell 51 and the backup power supply 53 at the bottom of the inner side are both used as energy storage components. They are electrically connected to the drive motor 41 and button 42 of the sampling mechanism 4 through internal circuits to provide power for the forward and reverse rotation of the drive motor 41. The Type-C charging port 54 at the top right of handle 2 is connected to the energy storage power supply 52 and the backup power supply 53 via a line. An external power supply can input power to the two power supplies through the Type-C charging port 54 to complete the power replenishment. When the device is in working condition, the energy storage power supply 52 prioritizes power supply to the drive motor 41. When the energy storage power supply 52 is low on power, the backup power supply 53 automatically switches to the circuit to ensure that the drive motor 41 continues to run and avoids interruption of blood sample collection due to power failure. Multiple power indicator lights 55 on the upper right side of handle 2 are electrically connected to the energy storage power supply 52 and the backup power supply 53. The on / off state of different indicator lights corresponds to the remaining power of different power supplies. When the energy storage power supply 52 has sufficient power, a specific indicator light will light up. As the power is consumed, the indicator light will gradually turn off, prompting the operator to charge in time. The power status of the backup power supply 53 is displayed through another set of indicator lights, making it easy for the operator to grasp the overall power reserve. The flame-retardant shell 51 is made of flame-retardant material, which can block the influence of external fire sources or high temperatures on the internal power supply, and at the same time prevent the spread of combustion caused by power supply failure, thus improving the safety of the device. The dual power supply design of energy storage power supply 52 and backup power supply 53 extends the device usage time after a single charge and reduces the need for frequent charging. The inclusion of the Type-C charging port 54 ensures compatibility with mainstream electronic devices, enhancing charging convenience; the status feedback of the power indicator light 55 allows operators to intuitively understand the power status and rationally arrange usage and charging times. The energy storage mechanism 5 achieves power protection through the flame-retardant shell 51, and the energy storage power supply 52 and the backup power supply 53 provide continuous power. The Type-C charging port 54 and the power indicator light 55 respectively ensure charging convenience and power visibility, and together provide power support for the stable operation of the sampling mechanism 4, enhancing the practicality and reliability of the device in mobile scenarios.

[0020] Reference Figure 1 , Figure 2 and Figure 5 A rubber sleeve 6 is fixedly connected to the top outer side of the conical nozzle 3, and the outer side of the rubber sleeve 6 is engaged with the bottom inner side of the outer cylinder shell 1; a magnetic suction piece 7 is fixedly connected to the top outer side of the conical nozzle 3, and the top of the magnetic suction piece 7 is magnetically connected to the bottom of the outer cylinder shell 1; multiple anti-slip holes 8 are provided on the outer side of the handle 2, and the inner and outer ends of the multiple anti-slip holes 8 are all rounded; the outer surface of the handle 2 is ergonomically designed and the outer surface is frosted. Specifically, the rubber sleeve 6 on the outer side of the top of the conical suction nozzle 3 is engaged with the bottom of the inner side of the outer cylinder shell 1. The rubber sleeve 6 deforms under pressure, filling the gap between the conical suction nozzle 3 and the outer cylinder shell 1 to form a sealing structure, preventing the blood sample in the liquid storage cylinder 45 from leaking from the connection. At the same time, the elastic properties of the rubber material can buffer the vibration transmission between the conical suction nozzle 3 and the outer cylinder shell 1, reducing the shaking effect during the blood sample aspiration process. The magnetic suction plate 7 at the top of the outer side of the conical suction nozzle 3 is magnetically connected to the bottom of the outer shell 1. The magnetic force enhances the connection strength between the conical suction nozzle 3 and the outer shell 1, preventing the conical suction nozzle 3 from accidentally falling off during use. The magnetic suction plate 7 cooperates with the rubber sleeve 6 to fix the conical suction nozzle 3 in both axial and radial directions, ensuring its relative position with the liquid storage cylinder 45 is stable and ensuring the smooth flow of the blood sample aspiration channel. Multiple anti-slip holes 8 on the outer side of the handle 2 come into contact with the fingers when gripping, increasing the friction between the hand and the handle 2 to prevent the device from slipping during operation; the rounded design of the inner and outer ends of the anti-slip holes 8 avoids pressure or scratches on the fingers when gripping, improving operating comfort; the ergonomic design of the outer surface of the handle 2 conforms to the natural grip posture of the palm, distributing hand pressure and reducing fatigue caused by long-term operation; the frosted process increases the surface roughness, further enhancing the friction when gripping, and together with the anti-slip holes 8, improves the stability of operation; When the conical nozzle 3 needs to be replaced, external force is applied to overcome the magnetic force of the magnetic suction plate 7 and the locking force of the rubber sleeve 6, and the conical nozzle 3 can be removed from the outer shell 1; when installing a new conical nozzle 3, the rubber sleeve 6 naturally locks in place, and the magnetic suction plate 7 automatically adsorbs, completing the quick replacement and adapting to the hygiene requirements of different sampling scenarios.

[0021] Working principle: Before the device is used, the energy storage mechanism 5 provides power support for the entire system; the flame-retardant shell 51 is fixed on the upper right side of the outer shell 1, and the internal energy storage power supply 52 and the backup power supply 53 are connected to the drive motor 41 and the button 42 through the line. The Type-C charging port 54 on the right side of the handle 2 can replenish the power of the dual power supply in advance. The power indicator light 55 reflects the remaining power through the on and off status, ensuring the power reserve of the device in mobile scenarios; the operator holds the handle 2 which is sleeved on the outside of the flame-retardant shell 51. Its ergonomic design and frosted process fit the palm of the hand, and the anti-slip holes 8 on the outside increase the friction and prevent slipping when holding it. When collecting blood samples, the conical suction nozzle 3 contacts the blood sample. The rubber sleeve 6 on the outer side of the nozzle is engaged with the bottom of the inner side of the outer shell 1. The magnetic suction piece 7 on the outer top is magnetically connected to the bottom of the outer shell 1. The double fixation ensures a sealed and stable connection. Press the button 42 on the top of the handle 2. The number of presses determines the number of rotations of the drive motor 41. The drive motor 41 rotates and drives the drive screw 43 to rotate. The guide posts 471 on all sides of the inner side of the outer shell 1 are embedded in the guide grooves 472 on the outer side of the rubber piston 44, restricting the rubber piston 44 from rotating with the screw and causing it to move upward along the axial direction. The rotation angle of the drive screw 43 changes with the number of revolutions of the drive motor 41, which changes the moving height of the rubber piston 44, thereby adjusting the volume and air pressure of the space below it to form negative pressure of different intensities. The negative pressure is transmitted to the conical suction nozzle 3 through the liquid storage cylinder 45. The amount of blood sample aspirated varies with the difference in negative pressure intensity. The pressure regulating hole 46 at the top of the liquid storage cylinder 45 balances the internal and external air pressure to ensure stable aspiration. The I-shaped column 481 on the outside of the drive screw 43 is rotatably connected to the mounting part 482 to provide radial support, prevent the screw from deviating when rotating, and ensure the accuracy of the thread fit. After blood sample collection is completed, press and hold button 42 for three seconds. Drive motor 41 receives a reverse signal, drives drive screw 43 to rotate in the opposite direction, and rubber piston 44 moves downward, compressing the space above liquid storage cylinder 45 and helping to seal liquid storage cylinder 45 to prevent blood sample leakage. If it is necessary to change the blood sample collection volume, the above operation can be repeated by adjusting the number of times button 42 is pressed to achieve different collection volumes. When the power of the energy storage power supply 52 is insufficient, the backup power supply 53 automatically switches to power supply to avoid data collection interruption; when replacing the conical suction nozzle 3, external force is applied to overcome the magnetic force of the magnetic suction plate 7 and the clamping force of the rubber sleeve 6. After the old suction nozzle is removed, the new suction nozzle can be quickly reset and fixed by the rubber sleeve 6 and the magnetic suction plate 7 to meet hygiene requirements. Throughout the process, the guide component 47 ensures the linear movement of the rubber piston 44, the stabilizing component 48 reduces screw vibration, the auxiliary structure improves operational stability, and the energy storage mechanism 5 ensures continuous power. All components work together to achieve quantitative collection, sealed storage, and portable use of blood samples, making it suitable for various mobile scenarios such as outdoor sampling and emergency rescue.
