Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a blood transfusion set that can keep the blood warm. Background Technology

[0002] In modern medical settings, blood transfusions and intravenous infusions are extremely common and crucial treatment methods. Traditional infusion devices generally lack heating functions, and the cold medication is directly injected into the patient's body, which can easily cause discomfort such as chills and vasoconstriction. These adverse reactions are more pronounced, especially for patients who are physically weak, children, or the elderly. This not only increases their physical suffering but may also interfere with the normal progress of subsequent treatments. While some simple heating devices have a certain warming effect, their installation methods are extremely limited. They either lack flexible fixing methods and cannot be quickly installed next to common infusion poles for immediate use, causing medical staff to spend a lot of time building additional support structures, or they cannot make proper use of the wall space in wards and operating rooms, resulting in cluttered equipment placement and occupying already limited work surfaces, causing inconvenience to medical staff during busy treatment processes.

[0003] Therefore, we propose a heat-preserving blood transfusion set. Utility Model Content

[0004] The purpose of this invention is to provide a blood transfusion set that can keep the blood warm.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat-preserving blood transfusion set, comprising a main body and a heating tube, wherein a clamping assembly and an installation assembly are provided on the back of the main body;

[0006] The clamping assembly includes a fixing block, a first spring, a pressing block, and a pull rod. Two sets of fixing blocks are provided and installed on the back of the main body. Four sets of first springs are provided, with one end of each spring installed inside two sets of fixing blocks. The pressing block is fixedly connected to the other end of the first spring. The pull rod is installed on one side of the pressing block and passes through the surface of the fixing block. The mounting assembly includes a mounting plate, a fixing plate, a clamping block, a slider, a second spring, a positioning rod, and a locking block. Four sets of fixing plates are provided and evenly installed on the main body. On the back of the body, a locking hole is provided on the inner side of the fixing plate. The locking block is installed on the inner side of the clamping block, and the locking block is adapted to the locking hole. The slider is installed on the back of the clamping block. Four sets of movable slots are provided on the front of the mounting plate. The slider is located in the movable slot. The positioning rod is installed in the movable slot and passes through the surface of the slider. The second spring is located in the movable slot, and one end of the second spring is fixedly connected to the inner side of the slider. The other end of the second spring is fixedly connected to the inner wall of the movable slot, and the second spring is sleeved on the outer side of the positioning rod. The second spring is in a stretched state.

[0007] As a further embodiment of this utility model: the inner extrusion surfaces of the two sets of extrusion blocks are set in an arc shape, and anti-slip pads are evenly installed on the extrusion surfaces of the extrusion blocks. Six sets of mounting holes are evenly opened on the front side of the mounting plate, and the mounting plate is installed on the wall through the mounting holes.

[0008] As a further embodiment of this utility model: an adjustment assembly is provided between the main body and the heating tube. The adjustment assembly includes a rotating shell, a retaining ring, a connecting block, a third spring, and a positioning steel ball. The rotating shell is installed on one side of the main body. A retaining groove is opened at the bottom of the inner wall of the rotating shell. The retaining ring is installed on the bottom surface of the connecting block. The retaining groove is adapted to the retaining ring. Four sets of placement grooves are evenly opened on the inner wall of the rotating shell. One end of the third spring is installed at the bottom of the placement groove. Multiple sets of positioning grooves are evenly opened on the outer wall surface of the connecting block. The positioning steel ball is installed on the other end of the third spring, and the positioning steel ball is adapted to the positioning groove.

[0009] As a further embodiment of this utility model: the left side of the connecting block is fixedly connected to the surface of the heating tube.

[0010] As a further embodiment of this utility model: a display screen is provided on the front of the main body, and an adjustment button is provided below the display screen.

[0011] As a further embodiment of this utility model, an interface is provided on the other side of the main body.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model utilizes a clamping assembly with a fixing block, a first spring, a squeezing block, and a pull rod. When the device needs to be quickly fixed to the infusion rod, pulling the pull rod causes the squeezing block to converge inward under the action of the first spring. After placing the infusion rod between the two sets of squeezing blocks, releasing the pull rod causes the first spring to rebound, and the squeezing block clamps the infusion rod. The anti-slip pad on its inner side increases friction, ensuring that the device is securely installed on the infusion rod, meeting the needs of temporary and rapid bedside use. Simultaneously, the mounting plate, fixing plate, clamping block, and second spring in the mounting assembly work together. First, the mounting plate is fixed to the wall through the six sets of mounting holes on the front. The clamping block, with the help of the slider, the second spring, and the positioning rod, is engaged in the locking hole on the inner side of the fixing plate, allowing the main body to be firmly installed on the wall. This enables the blood transfusion set to be quickly clamped and fixed to the infusion rod, allowing medical staff to perform bedside blood transfusion and infusion operations at any time, and it can also be installed on the wall, making reasonable use of wall space. This provides an efficient and flexible installation and fixing solution for warm blood transfusion and infusion work in different medical scenarios.

[0014] 2. This utility model, through the coordination of the rotating shell, retaining ring, connecting block, third spring, and positioning steel ball in the adjustment component, allows for easy adjustment of the heating tube angle. When the heating tube angle needs to be adjusted, a slight rotation of the heating tube causes the connecting block to rotate the retaining ring within the groove of the rotating shell. At this time, the third spring is compressed, and the positioning steel ball disengages from its original positioning groove. After rotating to the next positioning groove, the third spring rebounds, and the positioning steel ball engages in the new positioning groove, thus precisely fixing the heating tube. This allows for flexible angle adjustment, ensuring optimal contact between the heating tube and the infusion tubing, allowing for even and efficient heat transfer to the infusion fluid and preventing uneven heating. It also adapts to various complex usage scenarios, reducing inconvenience to medical personnel due to angle limitations.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 -Appendix Figure 6 This utility model discloses a heat-insulating blood transfusion and infusion set, comprising a main body 1 and a heating tube 2. A clamping assembly 3 and an installation assembly 4 are provided on the back of the main body 1. The clamping assembly 3 consists of two sets of fixing blocks 31, four sets of first springs 32, tightly fitting squeezing blocks 33, and a pull rod 34. The two sets of fixing blocks 31 are installed on the back of the main body 1. One end of each of the four sets of first springs 32 is installed inside the fixing blocks 31, and the other end is tightly connected to the squeezing blocks 33. When the device needs to be quickly fixed to the infusion rod, the pull rod 34 is pulled, the first springs 32 contract under force, and the squeezing blocks 33 converge inward, leaving sufficient space. After placing the infusion rod between the two sets of squeezing blocks 33, the pull rod 34 is released, the springs rebound, and the squeezing blocks 33 tightly clamp the infusion rod, enabling rapid bedside use. Medical staff can quickly start blood transfusion and infusion without complicated operations. The installation assembly 4 consists of an installation plate... 41. The mounting plate 42, clamping block 43, slider 44, second spring 45, positioning rod 46, and locking block 47 work together. The four sets of mounting plates 42 are evenly distributed at the corner of the back of the main body 1. The locking holes on the inner side are ready for docking. The four sets of movable grooves on the front of the mounting plate 41 provide the slider 44 with a space for movement. The slider 44 drives the clamping block 43 to move flexibly in the groove. The second spring 45 is in a stretched state, giving the clamping block 43 an inward elastic force. The locking holes of the locking block 47 are mutually compatible. When in use, the mounting plate 41 is first fixed to the wall with the six sets of mounting holes on the front. With the cooperation of the slider 44, spring and positioning rod 46, the clamping block 43 is accurately inserted into the locking hole, which can fix the main body 1. In this way, the blood transfusion and infusion set not only meets the convenience of bedside access, but also makes reasonable use of wall space, and can cope with various medical scenarios, creating an efficient and flexible fixing solution for warm blood transfusion and infusion work.

[0026] In Example 1, the inner extrusion surfaces of the two sets of extrusion blocks 33 are set to be arc-shaped. Anti-slip pads 35 are evenly installed on the extrusion surfaces of the extrusion blocks 33. The front of the mounting plate 41 is evenly provided with six sets of mounting holes. The mounting plate 41 is installed on the wall through the mounting holes. An adjustment component 5 is provided between the main body 1 and the heating tube 2. The adjustment component 5 includes a rotating shell 51, a retaining ring 52, a connecting block 53, a third spring 54, and a positioning steel ball 55. The rotating shell 51 is installed on one side of the main body 1. A retaining groove is provided at the bottom of the inner wall of the rotating shell 51. The retaining ring 52 is installed on the bottom surface of the connecting block 53. The retaining groove is adapted to the retaining ring 52. Four sets of placement grooves are evenly provided on the inner wall of the rotating shell 51. One end of the third spring 54 is installed on the bottom of the placement groove. Multiple sets of positioning grooves 56 are evenly provided on the outer surface of the connecting block 53. The positioning steel ball 55 is installed on the other end of the third spring 54, and the positioning steel ball 55 is adapted to the positioning groove 56.

[0027] Specifically, the inner squeezing surfaces of the two sets of squeezing blocks 33 are designed in an arc shape to fit snugly against the infusion rod, resulting in a larger contact area and more even force distribution. The squeezing surfaces of the squeezing blocks 33 are also evenly equipped with anti-slip pads 35, further enhancing friction and laying a solid foundation for quick bedside operation. The six sets of mounting holes evenly opened on the front of the mounting plate 41 can help the mounting plate 41 be installed on the wall. In the adjustment component 5, the rotating shell 51 is installed on one side of the main body 1, and the slot at the bottom of its inner wall is adapted to the retaining ring 52 on the bottom surface of the connecting block 53. The placement groove on the inner wall of the rotating shell 51, the third spring 54, and the positioning steel ball 55, together with the multiple sets of positioning grooves 56 on the outer wall of the connecting block 53, constitute a flexible angle adjustment system. When medical staff rotate the heating tube 2, the positioning steel ball 55 moves in and out of the positioning groove 56 as needed, easily adjusting the heating tube 2 to the ideal angle, ensuring fit with the infusion tube, and making heat transfer more efficient.

[0028] In embodiment 2, the left side of the connecting block 53 is fixedly connected to the surface of the heating tube 2, the front of the main body 1 is provided with a display screen 6, the lower part of the display screen 6 is provided with an adjustment button, and the other side of the main body 1 is provided with an interface.

[0029] Specifically, the left side of the connecting block 53 is firmly fixed to the surface of the heating tube 2, laying a solid foundation for the angle adjustment of the heating tube 2 and making the operation more stable and smooth. The front of the main body 1 is equipped with a display screen 6, which displays key data such as temperature in real time. The adjustment buttons below are neatly arranged, making it convenient for medical staff to quickly and accurately adjust. The interface on the other side of the main body 1 can be connected to a power cord to power the device.

[0030] Working principle:

[0031] First, during equipment installation, to quickly initiate bedside blood transfusion and infusion, pull the lever 34 of the clamping assembly 3. The four sets of first springs 32 contract, causing the squeezing blocks 33 to converge inwards, placing the infusion rod between the arc-shaped squeezing blocks 33 with anti-slip pads 35. Release the lever 34, and the springs will rebound, securing the equipment firmly to the infusion rod. If wall mounting is chosen, first use screws to pass through the six mounting holes of the mounting plate 41 to fix it to the wall. With the cooperation of the slider 44, the second spring 45, and the positioning rod 46, the clamping block 43 engages with the locking block 47 in the locking hole of the fixing plate 42, completing the fixation of the main body 1 to the wall. Then, connect the power to the other side of the main body 1. When the power interface is turned on, the heating circuit inside the main body 1 operates, causing the heating tube 2 to generate heat and transfer it to the infusion tube, thus heating the liquid inside the tube. At this time, if it is necessary to adjust the angle of the heating tube 2, rotate the heating tube 2. The connecting block 53, with the retaining ring 52, rotates in the slot of the rotating shell 51. The third spring 54 is compressed, and the positioning steel ball 55 disengages from the original positioning slot 56 and rotates to the appropriate angle. The spring rebounds, and the positioning steel ball 55 is inserted into the new positioning slot 56, ensuring that the heating tube 2 fits snugly with the infusion tube for efficient heat transfer. At the same time, medical staff can view key data through the display screen 6 on the front of the main body 1 and adjust the parameters as needed using the adjustment buttons below. Thus, the entire workflow is completed.
