Description

Technical Field

[0001] The present invention relates to the technical field of hematology, and in particular to an intelligent blood transfusion device for hematology. Background Art

[0002] In the process of blood supply, the hematology department needs to adapt to the corresponding intelligent blood transfusion device to replenish blood. Therefore, the intelligent blood transfusion device determines the overall blood transfusion quality. For example, the patent with announcement number CN204951810U discloses an intelligent blood transfusion device for hematology, comprising a blood transfusion bag body, wherein the blood transfusion bag is provided with three cavities: a saline chamber 1, a blood chamber, and a saline chamber 2. A catheter 1 is provided at the lower end of the saline chamber 1, a blood transfusion blood chamber is provided at the lower end of the blood chamber, and a catheter 2 is provided at the lower end of the saline chamber 2. The lower ends of the catheter 1, the blood transfusion blood chamber, and the catheter 2 are connected to an output tube, the end of the output tube is provided with a rubber stopper, and a controller is provided on the wall of the output tube. The controller includes an infrared induction velocimeter, a microprocessor, and a display. The controller is simple to operate, can automatically switch between delivering blood and delivering physiological saline, and can control the flow rate, effectively saving time and reducing the labor intensity of medical staff, avoiding cross infection, and accurately controlling the flow rate. The controller and infrared induction velocimeter are detachable and mountable. Another example is a patent with publication number CN114796697B, which discloses an intelligent blood transfusion device for hematology, comprising a bracket, a magnetic plate and a blood transfusion mechanism, wherein the blood transfusion mechanism comprises a blood transfusion cylinder, a clamping block and a clamping block are slidably connected inside the storage cylinder, a magnetic ring is inserted into the top of the storage cylinder, a disinfection chamber is formed at the bottom of the blood transfusion cylinder, a screw is inserted into the interior of the disinfection chamber, and a slider is threadedly connected to the front of the screw. After the blood bag is transfused, the gravity of the storage cylinder is reduced, and the weighing spring drives the storage cylinder to rise relative to the magnetic ring. The storage cylinder triggers a contact switch through a contact ring, and a corresponding number of blood bags are stored in the storage slot. The more blood bags there are, the greater the distance the storage cylinder drops, and the more contact switches are located above the contact ring, thereby ensuring that multiple groups of blood bags can be automatically replaced in sequence, thereby achieving automatic blood bag replacement. For example, the patent with announcement number CN216417962U discloses a blood transfusion device for hematology nursing, comprising a sleeve rod, a telescopic rod is inserted into the top of the sleeve rod, a fixed sleeve is sleeved on the outer surface of the sleeve rod, a thermostatic component is fixedly installed on one side of the fixed sleeve, a clamping plate is fixedly installed on one side of the telescopic rod, a clamping slot is opened on one side of the clamping plate, an I-shaped fixing plate is clamped inside the clamping slot, and through the setting of the thermostatic component, when in use, a storage bag containing plasma is placed on the hanger, and the heat conducting rod is connected to a universal power supply to start heating, so that the temperature inside the placement box is raised to a suitable temperature to heat the storage bag, thereby avoiding the plasma being too cold and causing discomfort to the patient, and through the setting of the clamping plate and the I-shaped fixing plate, the I-shaped fixing plate can be removed when needed, so that blood transfusion can be continued during the process of moving the patient, and there is no need to drag the entire device to move during the process of moving the patient; Most of the above-mentioned existing technologies have improved their overall structure. However, when the existing hematology intelligent blood transfusion device is used, when it heats the blood transfusion tube in the required state, the heating range is mostly limited. It is impossible to effectively heat the blood transfusion tube evenly over a wide range, so as to allow the transferred blood to be transported with better activity, and thus has certain usage limitations. Summary of the Invention

[0003] The object of the present invention is to provide an intelligent blood transfusion device for hematology to solve the problem proposed in the above-mentioned background art that when heating the blood transfusion tube in the required state, the heating range is mostly limited, and it is impossible to effectively perform uniform and multi-range heating treatment on the blood transfusion tube to allow the transferred blood to be transported with better activity.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a smart blood transfusion device for hematology, comprising a blood transfusion bag body, the lower end of which is docked with a preset supply hose, through which blood is transported; a reserved heat conduction component is provided at the lower end of the blood transfusion bag body, and a protective cover structure is rotatably docked on the outer side of the reserved heat conduction component, and a magnetic docking piece is fixedly connected to the inner side of the protective cover and the reserved heat conduction component, the inner end of the reserved heat conduction component is docked with the preset supply hose, and the inner end of the reserved heat conduction component is provided with an auxiliary self-moving structure, through which the preset supply hose is subjected to multi-range constant temperature treatment and an adjustable state is achieved.

[0005] Furthermore, the auxiliary self-moving structure is provided with a nested reserved part, and the nested reserved part is nested and docked in the middle end of the reserved heat conduction component, the inner side of the nested reserved part is fixedly connected with a docking torsion spring, and the inner end of the docking torsion spring and the inner side of the middle end of the reserved heat conduction component are docked with each other, and the outer side of the nested reserved part is docked with the preset supply hose.

[0006] Furthermore, a resistance docking piece is nested and installed at the lower end of the edge of the reserved heat conduction component, and a first spring is fixedly connected to the inner side of the resistance docking piece, and the first spring and the outer side of the reserved heat conduction component are docked with each other. A reserved guide groove is opened on the inner side of the reserved heat conduction component, and a movable resistance piece is nested and installed on the inner side of the reserved guide groove. The lower end of the movable resistance piece is docked with a memory metal component, and the memory metal component and the inner side of the reserved guide groove are docked with each other.

[0007] Furthermore, the preset supply hose is rolled up along the inner side of the reserved heat conduction component by nesting the reserved component, and the lower end of the preset supply hose is limited by the abutting docking component.

[0008] Furthermore, the memory metal component is reset and deformed upward along the inner side of the reserved guide groove during the heating process, and the memory metal component pushes the movable resistance part at the upper end to move upward along the inner side of the reserved heat conduction component, and the upward moving resistance part performs contact and pushing work between the mutually attracted magnetic docking parts.

[0009] Furthermore, an auxiliary self-warning structure is provided on the inner side of the edge of the reserved heat-conducting component, and the auxiliary self-warning structure automatically pops up to prompt the reserved heat-conducting component in an overheating state; the auxiliary self-warning structure is provided with a resistance docking reserved block, and the resistance docking reserved block is nested and docked on the inner side of the edge of the reserved heat-conducting component, and a second spring is fixedly connected to the inner side of the resistance docking reserved block, and the second spring is docked with the inside of the reserved heat-conducting component.

[0010] Furthermore, the outer side of the movable resistance member is fixedly connected to an external docking member, and the external docking member is docked with the outer side of the resistance docking reserved block, and a contact switch assembly is fixedly connected between the outer side of the movable resistance member and the inner side of the reserved heat conduction component, and the contact switch assemblies are staggered.

[0011] Furthermore, in the process of the movable resistance member moving outward along the inner side of the reserved guide groove, the external docking member on the outside moves along the outer side of the resistance docking reserved block, so that the external docking member moves from a closed limiting state relative to the resistance docking reserved block to a closed limiting state separated from the external docking member, so that the external docking member moves outward through the second spring to perform the ejection work.

[0012] Furthermore, after the movable resistance member moves upward due to the deformation thrust of the memory metal component, the contact switch assembly between the outer side of the movable resistance member and the inner side of the reserved heat conduction component changes from an interlaced state to a mutual contact state, and the contact switch assembly transmits an electrical signal to a preset buzzer component inside the reserved heat conduction component to perform a warning.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This intelligent blood transfusion device for hematology uses an auxiliary self-moving structure to maintain a constant temperature over multiple ranges for the pre-set supply hose and achieve an adjustable state. The entire pre-set supply hose is coiled and wound inside a reserved heat conduction component. Compared with the traditional single-line through-type heating method, this device can more evenly conduct heat to a larger area of ​​the pre-set supply hose without increasing the pipe penetration range, thereby effectively and uniformly heating the blood transfusion tube over multiple ranges, allowing the transferred blood to be transported with greater activity. Furthermore, the preset supply hose is wound up along the inner side of the reserved heat-conducting component by the docking torsion spring and the nested reserved part. The coiled preset supply hose ensures its heating range while allowing the user to adjust the unwinding length of the preset supply hose by simply pulling the contact docking part outwards as needed, thereby effectively controlling the length of the preset supply hose under different operating requirements. Moreover, the support structure of the docking torsion spring and the nested reserved part allows the hose to be quickly wound back, thereby avoiding undesirable phenomena such as the preset supply hose being wound due to excessive length, thereby improving the practicality of the device. Furthermore, an auxiliary self-warning structure is provided, which automatically pops up a warning to the reserved heat-conducting component in an overheating state. When the device is left unattended for a long time, if the reserved heat-conducting component continues to heat up, the memory metal component inside it will deform and move upward, thereby pushing the outer movable resistance piece to move along the inner side of the reserved guide groove. The upward moving resistance piece contacts and pushes the mutually attracted magnetic docking pieces, thereby allowing the reserved heat-conducting component to be separated from the cover plate structure closed by the magnetic docking piece. Furthermore, the movable resisting member in the upward state will move along the outer side of the resisting docking reserved block through the outer external docking member, so that the external docking member moves from the closed limit state with respect to the resisting docking reserved block to the closed limit state separated from the external docking member, and the external docking member moves outwardly through the second spring to perform the ejection work, thereby automatically popping open the reserved heat conduction component and its cover plate while disengaging the attracted position, effectively performing the conversion of the thermally closed state and automatically performing the heat dissipation work; Furthermore, while the movable resistance piece moves upward due to the deformation thrust of the memory metal component, the outer side of the movable resistance piece that is subjected to the force will change from an interlaced state to a mutual contact state with the contact switch component between the inner side of the reserved heat conduction component, so that the contact switch component transmits an electrical signal to the buzzer component preset inside the reserved heat conduction component to perform an alarm, thereby prompting the staff and the patient to perform adjustment work.
