Description

Technical Field

[0001] This utility model relates to the field of blood collection equipment technology, and more specifically, to a blood collection device for physical examination and nursing care. Background Technology

[0002] Blood testing is a crucial method in physical examinations, nursing care, and disease diagnosis. By analyzing various biological and physicochemical properties of the patient's blood, potential diseases can be identified, changes in bodily functions can be monitored, and health management and disease treatment can be guided. Before conducting blood tests, blood must first be drawn from the patient. Blood collection requires high frequency and high precision, especially in scenarios such as outdoor physical examinations and mobile healthcare, which places higher demands on the portability and functional integration of blood collection devices. When collecting blood in the field, medical staff often use blood collection pads made of cotton, sponges, or air bags to support the patient's arm for easy needle insertion. However, existing blood collection devices are relatively simple in function, only used to support the patient's arm, and require additional storage and transport during field blood collection, making them inconvenient to use. Utility Model Content

[0003] To address the technical problem of limited functionality in existing blood collection devices, this invention provides a blood collection device for physical examinations and nursing care. This device can support the limbs of individuals during blood collection and ensure stable support. The shape of the support cloth can be adjusted as needed, and it also has a storage function for storing blood collection-related equipment and medicines.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a blood collection device for physical examination and nursing, including a first storage box, a second storage box, and a support cloth. The two opposite sides of the support cloth are respectively connected to the first storage box and the second storage box. The first storage box is provided with a first opening, which is opened on the side facing the second storage box. The second storage box is provided with a second opening, which is opened on the side facing the first storage box. A limiting device for limiting the distance between the first storage box and the second storage box is also provided. The two ends of the limiting device are respectively connected to the first storage box and the second storage box.

[0005] In this technical solution, a support cloth is used to support the patient's limb. The patient's limb can be considered as a quasi-cylindrical structure. The two ends of the support cloth are connected to a first storage box and a second storage box, respectively. During blood collection, as long as the distance between the first and second storage boxes is less than the width of the support cloth, the support cloth can bend downwards to form an arc-shaped surface, thus conforming to the patient's limb and supporting it. Simultaneously, because the support cloth is in a state of being lower in the middle and higher on both sides, if the patient's limb moves in the width direction of the support cloth, it must first overcome its own weight and the friction between the limb and the support cloth. This restricts the movement of the patient's limb, ensuring that the patient's limb position remains relatively stable during blood collection. Patients have different body shapes and limb thicknesses, resulting in different concave curvatures of the support cloth. The concave curvature of the support cloth is determined by the distance between the first and second storage boxes. Therefore, a limiting device is also needed to limit the relative distance between the first and second storage boxes, preventing changes in the concave curvature of the blood collection cloth due to changes in the distance between them during use. Besides holding the blood collection cloth, the first and second storage boxes also serve a storage function. Various equipment needed for blood collection and the collected blood sample can be placed in the first and second storage boxes respectively, achieving storage and separating the two to prevent blood sample contamination of unused equipment. The first and second storage boxes are respectively provided with a first opening and a second opening. Various items are placed into the first or second storage box through the first or second opening. When the distance between the first and second storage boxes decreases to the point where they are touching, both the first and second openings are blocked, thus achieving a closed state for the first and second storage boxes. The limiting device restricts the displacement between the first and second storage boxes, ensuring that they remain closed and do not accidentally fall out.

[0006] Preferably, the limiting device is a telescopic rod, which includes an inner rod and an outer cylinder with an open end. One end of the inner rod is inserted into the outer cylinder from the open end and is slidably connected to the outer cylinder. A limiting member is also provided on the outer cylinder, which is connected to the inner rod. The end of the inner rod away from the outer cylinder is connected to the first storage box, and the end of the outer cylinder away from the inner rod is connected to the second storage box.

[0007] Preferably, the limiting member is a fastening bolt, and the outer cylinder has a fastening threaded hole that penetrates the cylinder wall. The fastening threaded hole is threadedly connected to the fastening bolt, and the fastening bolt is inserted into the outer cylinder and abuts against the outer wall surface of the inner rod.

[0008] Preferably, the first storage box is provided with a connecting structure, and the inner rod is detachably connected to the first storage box through the connecting structure.

[0009] Preferably, the connecting structure includes a snap-fit ​​block and a baffle. The snap-fit ​​block is fixedly installed on the outer wall of the first storage box. The baffle is disposed on the side of the snap-fit ​​block away from the first storage box. The inner rod has a snap-fit ​​groove with a shape matching the snap-fit ​​block at the end away from the outer cylinder. The lower end of the snap-fit ​​groove is open. The snap-fit ​​groove snaps into the snap-fit ​​block. The outer cylinder is rotatably connected to the second storage box.

[0010] Preferably, the baffle is further provided with a locking device for locking the rotation of the telescopic rod, and the locking device is connected to the inner rod.

[0011] Preferably, the locking device includes a plug rod and an elastic element. The baffle has a mounting cavity. The plug rod is slidably installed in the mounting cavity and protrudes from the side of the baffle away from the first storage box. The plug rod has an abutment portion. The elastic element is sleeved on the plug rod. The two ends of the elastic element abut against the abutment portion and the cavity wall of the mounting cavity, respectively. The inner rod has an insertion hole, which is inserted into the plug rod.

[0012] Preferably, a barrier mesh is provided in the first opening and the second opening respectively, the barrier mesh closing the first opening or the second opening, and the barrier mesh being detachably connected to the wall of the first opening or the wall of the second opening by a zipper.

[0013] Preferably, the bottom surfaces of the first storage box and the second storage box are respectively provided with anti-slip pads.

[0014] Preferably, the upper surface of the support cloth is further provided with a plurality of friction pads along its length.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the first and second storage boxes support the cloth, providing support while also storing items. A limiting device is provided to restrict the relative distance between the first and second storage boxes, ensuring that they do not move relative to each other and cause a change in the concave curvature of the cloth. The first opening of the first storage box faces the second storage box, and the second opening of the second storage box faces the first storage box. This allows the first and second openings to be sealed when the distance between the first and second storage boxes is reduced to a point where they fit together, thus completing the closure of the first and second storage boxes.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "long," and "short" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 like Figure 1As shown, a blood collection device for physical examination and nursing includes a first storage box 1, a second storage box 2, and a support cloth 3. The support cloth 3 is connected to the first storage box 1 and the second storage box 2 on opposite sides, respectively. The first storage box 1 has a first opening facing the second storage box 2, and the second storage box 2 has a second opening facing the first storage box 1. A limiting device 4 is also provided to limit the distance between the first storage box 1 and the second storage box 2, with both ends connected to the first storage box 1 and the second storage box 2, respectively. The support cloth 3 is used to support the patient's limb. The patient's limb can be considered a cylindrical structure. The two ends of the support cloth 3 are connected to the first storage box 1 and the second storage box 2, respectively. During blood collection, as long as the distance between the first storage box 1 and the second storage box 2 is less than the width of the support cloth 3, the support cloth 3 can bend downwards to form an arc-shaped surface, thus conforming to the patient's limb and supporting it. Simultaneously, because the support cloth 3 is in a state of being lower in the middle and higher on both sides, if the patient's limb moves in the direction of the width of the support cloth 3, it must first overcome its own weight and the friction between the limb and the support cloth 3. This restricts the movement of the patient's limb, ensuring that the patient's limb position remains relatively stable during blood collection. Different patients have different body shapes and limb thicknesses, resulting in different concave curvatures of the support cloth 3. The concave curvature of the support cloth 3 is determined by the distance between the first storage box 1 and the second storage box 2. Therefore, a limiting device 4 is also needed to limit the relative distance between the first storage box 1 and the second storage box 2, to prevent changes in the distance between the first storage box 1 and the second storage box 2 during use, which would cause changes in the concave curvature of the support cloth 3. In addition to holding the support cloth 3, the first storage box 1 and the second storage box 2 also serve a storage function. Various equipment needed for blood collection and the collected blood sample can be placed in the first storage box 1 and the second storage box 2 respectively, achieving storage and separating the two to prevent blood samples from contaminating unused equipment. The first storage box 1 and the second storage box 2 are respectively provided with a first opening and a second opening. Various items are placed into the first storage box 1 or the second storage box 2 through the first opening or the second opening. When the distance between the first storage box 1 and the second storage box 2 is reduced to the point where they are close together, the first opening and the second opening are blocked, thereby achieving a closed state for the first storage box 1 and the second storage box 2. The limiting device 4 can limit the displacement between the first storage box 1 and the second storage box 2, thereby ensuring that the first storage box 1 and the second storage box 2 are in a closed state and will not accidentally fall out.

[0021] like Figure 1As shown, the limiting device 4 is a telescopic rod, which includes an inner rod 41 and an outer cylinder 42 with an open end. One end of the inner rod 41 is inserted into the outer cylinder 42 from the open end and is slidably connected to the outer cylinder 42. A limiting member is also provided on the outer cylinder 42, which is connected to the inner rod 41. The end of the inner rod 41 away from the outer cylinder 42 is connected to the first storage box 1, and the end of the outer cylinder 42 away from the inner rod 41 is connected to the second storage box 2. The telescopic rod adjusts the distance between the first storage box 1 and the second storage box 2 by extending and retracting. When adjustment is needed, medical personnel can disconnect the connection between the limiting member and the inner rod 41 to freely adjust the distance between the first storage box 1 and the second storage box 2. After the medical personnel adjust it to a suitable position, they connect the limiting member to the inner rod 41 to fix the inner rod 41, making the length of the telescopic member unchangeable, thereby fixing the distance between the first storage box 1 and the second storage box 2.

[0022] like Figure 1 As shown, the limiting component is a fastening bolt 43. A threaded hole penetrating the outer cylinder 42 is provided on its wall, and the fastening bolt 43 is threadedly connected to the threaded hole. The fastening bolt 43 is inserted into the outer cylinder 42 and abuts against the outer wall surface of the inner rod 41. The fastening bolt 43 is installed on the outer cylinder 42 through the threaded hole, and its position cannot be changed. Medical personnel can insert or remove the fastening bolt 43 from the outer cylinder 42 by rotating it. When the fastening bolt 43 is inserted into the outer cylinder 42 and abuts against the outer wall surface of the inner rod 41, friction is generated between it and the inner rod 41, thus restricting the inner rod 41 from sliding within the outer cylinder 42 and fixing its position. When it is necessary to adjust the distance between the first storage box 1 and the second storage box 2, simply rotate the fastening bolt 43 in the opposite direction to loosen it. This design allows the fastening bolt 43 to be fixed at any position of the inner rod 41, achieving stepless adjustment of the telescopic rod length.

[0023] Example 2 This embodiment is similar to Embodiment 1 above, except that, as Figure 1 As shown, the first storage box 1 is provided with a connecting structure, and the inner rod 41 is detachably connected to the first storage box 1 through the connecting structure. Since the first opening and the second opening are located on the side of the first storage box 1 and the second storage box 2 facing each other, they will be blocked by the telescopic rod when taking or putting in items through the first opening and the second opening. Therefore, the inner rod 41 is designed to be detachably connected to the first storage box 1 through the connecting structure. When it is necessary to take or put in items, the inner rod 41 can be detached from the first storage box 1, so that the first storage box 1 can move freely to a certain extent without being restricted by the telescopic parts, making it easier to expose the first opening and the second opening for taking or putting in items.

[0024] like Figure 3 , 4As shown, the connecting structure includes a snap-fit ​​block 11 and a baffle 12. The snap-fit ​​block 11 is fixedly installed on the outer wall of the first storage box 1. The baffle 12 is disposed on the side of the snap-fit ​​block 11 away from the first storage box 1. The inner rod 41 has a snap-fit ​​groove 411 with a shape matching the snap-fit ​​block 11 at the end away from the outer cylinder 42. The lower end of the snap-fit ​​groove 411 is open, and the snap-fit ​​groove 411 snaps into the snap-fit ​​block 11. The outer cylinder 42 is rotatably connected to the second storage box 2. The snap-fit ​​groove 411 on the inner rod 41 makes the inner rod 41 form a hook-like structure, which can hook the snap-fit ​​block 11. The outer cylinder 42 can rotate to drive the inner rod 41 to hook or hook out the snap-fit ​​block 11, realizing the connection and fixation of the snap-fit ​​groove 411 and the snap-fit ​​block 11. The baffle 12 is used to close the end of the snap-fit ​​block 11 away from the first storage box 1 to prevent the inner rod 41 from accidentally sliding out from this end during use.

[0025] like Figure 3 , 4 As shown, the baffle 12 is also equipped with a locking device 5 for locking the rotation of the telescopic rod, and the locking device 5 is connected to the inner rod 41. The locking device 5 can lock the snap-fit ​​groove 411 on the inner rod 41 together with the snap-fit ​​block 11, thereby ensuring that the telescopic rod will not be accidentally rotated during operation, thus preventing it from losing its limiting effect on the first storage box 1 and the second storage box 2.

[0026] like Figure 3 As shown, the locking device 5 includes a plug rod 51 and an elastic element 52. A mounting cavity is provided within the baffle 12. The plug rod 51 is slidably mounted within the mounting cavity and protrudes from the side of the baffle 12 away from the first storage box 1. An abutment portion 53 is provided on the plug rod 51. The elastic element 52 is sleeved on the plug rod 51, with both ends of the elastic element 52 abutting against the abutment portion 53 and the cavity wall of the mounting cavity, respectively. An insertion hole 412 is provided on the inner rod 41, and the insertion hole 412 is inserted into the plug rod 51. When it is necessary to connect or disconnect the inner rod 41 from the locking block 11, medical personnel can pull the end of the plug rod 51 protruding from the baffle 12 away from the first storage box 1, thereby causing the plug rod 51 to retract into the mounting cavity without obstructing the movement of the inner rod 41. Medical staff adjust the position of the telescopic component and then release the plug rod 51. Under the action of the elastic component 52, the plug rod 51 is reinserted into the space between the baffle 12 and the first storage box 1. If the inner rod 41 hooks the snap block 11 at this time, the plug rod 51 is inserted into the insertion hole 412 on the inner rod 41, thereby fixing the telescopic rod.

[0027] Example 3 This embodiment is similar to Embodiment 1 above, except that, as Figure 2As shown, a barrier net 6 is provided in the first opening and the second opening respectively. The barrier net 6 closes the first opening or the second opening. The barrier net 6 is detachably connected to the wall of the first opening or the wall of the second opening via a zipper. The barrier net 6 is used to separate and close the first storage box 1 and the second storage box 2 to prevent items from leaking out.

[0028] like Figure 2 As shown, the bottom surfaces of the first storage box 1 and the second storage box 2 are respectively equipped with anti-slip mats 7. The anti-slip mats 7 are made of materials such as rubber, silicone, and latex. When the first storage box 1 and the second storage box 2 are placed on a work surface such as a table or chair, the anti-slip mats 7 can increase the friction between the first storage box 1 and the second storage box 2 and the work surface, preventing the first storage box 1 and the second storage box 2 from moving during use and affecting the operation of medical staff.

[0029] like Figure 1 As shown, the upper surface of the dressing 3 is also provided with multiple friction pads 8 along its length. The friction pads 8 are made of materials such as silicone, thermosetting ink, and adhesive. The friction pads 8 can increase the friction between the patient's torso skin and the dressing 3, preventing the patient's torso from easily moving and slipping off the dressing 3.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
