Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a blood matching device that facilitates traceability. Background Technology

[0002] In the workflow of modern transfusion medicine, properly preserving the patient's blood sample, donor's blood sample, used blood bag, and other relevant crossmatching materials after the transfusion is extremely important. This is not only to clarify responsibility and determine whether there is a transfusion error or blood product quality problem when the patient experiences an abnormal reaction or suspected transfusion-related problem after the transfusion, providing crucial evidence for handling medical disputes; but also because some diseases have a window period, such as HIV, hepatitis B, and hepatitis C, which may not be detectable during the transfusion due to the window period. Preserving blood samples and related materials allows for re-examination of the blood sample if infection is discovered some time after the transfusion, tracing the source of infection and promptly preventing the spread of the disease.

[0003] However, the current sample preservation methods commonly used in blood transfusion departments have many drawbacks. In daily operations, patient blood samples and donor blood samples are stored separately on test tube racks, blood typing cards are placed centrally on blood typing racks, and blood bag samples and donor blood braids are also stored independently. After sorting, all samples and materials are stored together in a refrigerator. This decentralized management model causes great difficulties for staff in verification. Staff need to search back and forth between test tube racks, blood typing racks, and other storage locations for the required samples. This process is not only cumbersome and time-consuming, severely reducing work efficiency, but also greatly increases the difficulty of management due to the dispersed storage of samples, significantly increasing the risk of sample loss. Once a sample is lost, subsequent traceability work and related medical treatment will face significant obstacles. Utility Model Content

[0004] The present invention aims to provide a blood matching device that facilitates traceability, in order to solve the problems of low work efficiency, high management difficulty and easy loss of samples caused by the scattered storage of samples in the existing blood transfusion department.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a blood matching device for easy traceability, comprising a base, on which a plurality of placement units are provided, each placement unit comprising a label placement box, a donor sample placement part and a patient blood sample placement part, the donor sample placement part being used to store the donor blood sample and the donor blood bag, the base between the donor sample placement part and the patient blood sample placement part being provided with a blood matching card placement part and a blood bag placement part, and the label placement box being fixedly connected to the base.

[0006] The beneficial effects of this solution are as follows: This technical solution integrates various samples and materials involved in the blood transfusion process into multiple specific areas of a single device, which greatly improves the convenience of sample management in the blood transfusion department and has many outstanding beneficial effects.

[0007] (1) Improve work efficiency: In the past, during the verification process, staff had to search for samples in multiple places such as test tube racks and blood type racks, which wasted a lot of time. However, this device centrally stores donor blood samples, donor blood braids, patient blood samples, blood matching cards, blood bags, etc. in a specific placement unit. During the verification process, staff only need to be in the corresponding area of ​​the device to quickly locate and obtain the required samples and materials, which greatly saves the time of searching for samples and significantly improves work efficiency.

[0008] (2) Reduced management difficulty: In the traditional decentralized management model, samples and materials are scattered in different places, making management very complicated. This blood matching device adopts an integrated design with a reasonable layout of each placement unit, allowing various samples and materials to be stored in an orderly manner. Staff can centrally and efficiently manage and monitor the status of samples, reducing management difficulty and improving management accuracy.

[0009] (3) Reduce the risk of sample loss: In the traditional model, samples are scattered and are easily lost during the search and transfer process. This device integrates relevant samples and materials into one device, reducing the risk of sample loss due to human negligence and multiple transfers, and providing stable sample support for subsequent tracing and medical work.

[0010] (4) Facilitating traceability: Each placement unit is equipped with a label placement box, allowing staff to affix unique identification labels to the samples and materials in each placement unit and record key data such as sample origin and blood matching information in detail. In the event of transfusion abnormalities or medical disputes, the source and processing of the samples can be quickly traced through the labels, facilitating the investigation of the truth and providing strong evidence support for the handling of medical disputes.

[0011] Furthermore, the donor sample placement section is equipped with a braid placement slot and a donor blood sample placement slot, and a sealing cap is detachably connected to the braid placement slot.

[0012] The beneficial effects of this solution are as follows: This solution includes a blood braid placement slot and a donor blood sample placement slot in the donor sample placement area, and the blood braid placement slot is equipped with a removable sealing cap. This not only prevents blood from flowing out of the blood braid, avoiding contamination of the blood matching device and the surrounding environment, protecting sample quality, reducing the risk of sample contamination, and ensuring accurate test results; but also, the removable design facilitates the placement and removal of donor blood braids by staff, as well as the cleaning and maintenance of the blood braid placement slot.

[0013] Furthermore, the patient blood sample placement section is equipped with a patient blood sample placement slot, which is used to store patient blood samples.

[0014] The beneficial effects of this solution are as follows: placing patient blood samples in a centralized patient blood sample storage tank not only facilitates quick location and retrieval by staff during verification and tracing, greatly improving work efficiency, but also effectively distinguishes patient blood samples from other samples, reducing the risk of confusion.

[0015] Furthermore, the blood matching card placement part is provided with a receiving slot and several card receiving slots. The card receiving slots are connected to the receiving slots, and adjacent card receiving slots are spaced apart. The blood matching card is inserted into the card receiving slot.

[0016] The beneficial effects of this solution are as follows: In actual blood matching work, some patients may need to use multiple blood matching cards due to factors such as their condition or transfusion requirements. The multiple card slots in this technical solution allow multiple blood matching cards to be stored in a single card holder, fully meeting the diverse blood matching needs of different patients. Furthermore, the spaced card slots prevent blood matching cards from being squeezed or overlapping, ensuring that the information on the cards is clear and easy to read, and facilitating staff to quickly and accurately retrieve and verify specific blood matching cards, thus improving work efficiency and accuracy.

[0017] Furthermore, the blood bag placement section is provided with a blood bag placement groove, the longitudinal section of which is inverted trapezoidal in shape.

[0018] The beneficial effects of this solution are as follows: The blood bag placement tray adopts an inverted trapezoidal shape, which has multiple advantages. After transfusion, the inverted trapezoidal design prevents residual blood from tipping over, avoiding blood spillage, reducing the risk of biological contamination, and creating a safe environment. Its spacious upper section allows staff to quickly retrieve and place blood bags, significantly improving efficiency when handling large quantities of blood bags.

[0019] Furthermore, the base has a first groove that runs horizontally through the donor blood sample placement slot and a second groove that runs horizontally through the patient blood sample placement slot on its side.

[0020] The beneficial effects of this solution are as follows: This technical solution features a first groove that horizontally penetrates the donor blood sample placement slot and a second groove that penetrates the patient blood sample placement slot on the side of the base. The first groove divides the donor blood sample placement slot into upper and lower parts, and the second groove similarly divides the patient blood sample placement slot. This design significantly improves the ease of cleaning the blood matching device, allowing staff to directly clean the blood sample placement slots from the side, effectively removing dirt from hard-to-reach areas, maintaining the hygiene of the device, and thus extending its service life. Furthermore, the grooves reduce the amount of material used in the base, lightening the overall weight of the device and making it easier for staff to move and operate the blood matching device.

[0021] Furthermore, clamping units are provided on both sides of the card slot, which can clamp the blood matching card.

[0022] The beneficial effects of this solution are as follows: clamping units are provided on both sides of the card slot. Each clamping unit applies precise force to firmly fix the blood matching card from both sides. This not only prevents the blood matching card from shaking or shifting during storage and transportation, but also prevents the blood matching card from being damaged due to collisions, providing a reliable guarantee for the smooth implementation of blood matching traceability work.

[0023] Furthermore, each side of the card slot is provided with a through hole communicating with the first groove and the second groove. Each clamping unit includes a fixing block and a clamping block. The clamping block is slidably mounted on the base and can pass through the through hole. The side of the clamping block near the blood matching card is an inclined surface. The fixing block is arranged opposite to the clamping block and is fixedly connected to the base. An elastic element is fixedly connected between the fixing block and the clamping block.

[0024] The beneficial effects of this solution are as follows: When inserting the blood matching card, the inclined surface of the clamping block guides the card smoothly into place, while the clamping block slides on the base and compresses the elastic element. Relying on the elastic potential energy accumulated by the elastic element, the blood matching card is firmly clamped. When removing the blood matching card, it can be simply pulled out, making the operation convenient and greatly improving the efficiency of the blood matching card retrieval and placement process.

[0025] Furthermore, a cover is hinged to the base.

[0026] The beneficial effects of this solution are as follows: The addition of a primary cover significantly improves the reliability of sample preservation and testing. When the device is placed in a refrigerator, the primary cover prevents sample and material contamination and avoids interference from external impurities. During verification, because the sample is uncontaminated, the test data is more reliable, effectively improving the accuracy of the test results. This design reduces the risk of sample contamination, providing strong support for the testing and traceability work of the blood transfusion department.

[0027] Furthermore, a second cover is hinged to the base at both the first and second grooves.

[0028] The beneficial effects of this solution are as follows: the No. 2 cover can effectively seal the No. 1 and No. 2 grooves, preventing external dust, microorganisms, etc. from entering the blood sample placement slot through the grooves, reducing the risk of sample contamination, ensuring sample quality, and ensuring the accuracy of subsequent blood matching and testing results.
