[0022] A cover plate is bolted to the back of the plastic shell, and the cover plate seals the opening of the mounting cavity.

[0023] Furthermore, in order to better realize this utility model, the mounting cavity includes a first chamber and a second chamber separated by a partition. The battery is installed in the first chamber, and a control unit is also installed in the second chamber. The battery and the wire are electrically connected to the control unit so as to use the control unit to control the heating temperature of the infusion heating belt.

[0024] Furthermore, in order to better realize this utility model, a button and a display are also installed on the front of the plastic shell.

[0026] This utility model provides a blood transfusion assembly with heating and anti-accidental tearing functions, including a blood transfusion bag, a blood transfusion tube, a plastic shell, and a battery. The blood transfusion bag has a first hook at the top and a sealed port at the bottom. The first hook is attached to an infusion stand.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example:

[0039] like Figures 1-5As shown, the blood transfusion assembly with heating and anti-accidental tearing functions provided in this embodiment includes a blood bag 100, a blood transfusion tube 300, a plastic shell 400, and a battery 700. The upper end of the blood bag 100 is provided with a first hook 110 and the lower end is provided with a sealing port 120. The first hook 110 is hooked to the infusion stand 200. One end of the blood transfusion tube 300 is provided with a blood transfusion needle 310 and the other end is provided with a puncture device 320. The puncture device 320 is inserted into the sealing port 120 to connect the blood transfusion tube 300 and the blood bag 100. The top of the plastic shell 400 is provided with a second hook 410 and the bottom is fixed with a rubber. The rubber strip 420 has an installation cavity in the plastic shell 400. One end of the rubber strip 420 away from the plastic shell 400 is connected to an infusion heating belt 430. The second hook 410 is hung on the infusion stand 200. The infusion heating belt 430 is fitted onto a section of the infusion tube 300. The rubber strip 420 is detachably connected to the outer wall of the blood transfusion bag 100 through the first connecting part 500, and the rubber strip 420 is detachably connected to the puncture device 320 through the second connecting part 600. The battery 700 is installed in the installation cavity. The rubber strip 420 has a wire inside, and the infusion heating belt 430 is electrically connected to the battery 700 through the wire.

[0040] When using this transfusion assembly, the battery 700 is first installed in the mounting cavity. Then, the rubber strip 420 is connected to the outer wall of the blood bag 100 using the first connecting part 500. Next, the puncture device 320 is inserted into the sealing port 120 at the lower end of the blood bag 100. Then, the puncture device 320 and the rubber strip 420 are connected using the second connecting part 600. After that, the first hook 110 and the second hook 410 are both hung on the infusion stand 200. Then, the infusion heating belt 430 is placed over a section of the transfusion tube 300. Since the infusion heating belt 430 is electrically connected to the battery 700 through the wires built into the rubber strip 420, the infusion heating belt 430 generates heat when energized, thereby heating the transfusion tube 300 and the blood flowing in the transfusion tube 300. Furthermore, since the second hook 410 at the upper end of the plastic shell 400 is hung on the IV stand 200, and the rubber strip 420 at the lower end of the plastic shell 400 is connected to the blood bag 100 and the puncture device 320 at the end of the transfusion tube 300 via the first connecting part 500 and the second connecting part 600 respectively, the blood bag 100 in the blood transfusion assembly provided in this embodiment is not only suspended on the IV stand 200 via the first hook 110, but also via the aforementioned second hook. 410, rubber strip 420 and first connecting part 500 are also suspended on the infusion stand 200, thus providing double protection for the blood bag 100 and effectively preventing the blood bag 100 from falling off the infusion stand 200. Furthermore, the puncture device 320 on the infusion tube 300 is also suspended on the infusion stand 200 through the second hook 410, rubber strip 420 and second connecting part 600. In this way, the puncture device 320 on the infusion tube 300 can be prevented from accidentally falling off the blood bag 100.

[0041] With the above structure, the blood transfusion assembly provided in this embodiment achieves the function of heating the transfusion tube 300 through the plastic shell 400, the wire inside the rubber strip 420, and the infusion heating belt 430. It also achieves the function of preventing the blood bag 100 and the transfusion tube 300 from falling off accidentally during use by means of the second hook 410, the plastic shell 400, the rubber strip 420, the first connecting part 500 and the second connecting part 600. The overall structure is simple, easy to use, highly practical, and easy to promote and apply.

[0042] It should be noted that the blood transfusion bag 100 and the infusion heating belt 430 mentioned above are the same as existing technologies. It is particularly noteworthy that the infusion heating belt 430 is widely used in existing technologies. Its principle is to generate heat by passing electricity through a heating wire. Its structure generally involves placing the heating wire inside a high-temperature resistant non-woven fabric, sponge, or silicone sheet, providing good flexibility and allowing it to be bent. Since this is existing technology, it will not be described in detail here. The plastic shell 400 mentioned above is a rigid shell, and the rubber strip 420 mentioned above is a flexible strip.

[0043] An optional implementation of this embodiment is as follows: The first connecting part 500 includes a first silicone strip 510, a silicone plate 520, and double-sided adhesive (not shown in the figure), wherein:

[0044] One end of the first silicone strip 510 is fixed to the outer wall of the middle part of the rubber strip 420 by heat fusion. The silicone plate 520 is integrally formed and fixed to the first silicone strip 510. The silicone plate 520 is located at the other end of the first silicone strip 510. The aforementioned double-sided adhesive is pre-set on the outer wall of the blood transfusion bag 100, and the silicone plate 520 is adhered to the outer wall of the blood transfusion bag 100 by the double-sided adhesive. It should be noted that the double-sided adhesive is pre-set on the outer wall of the blood transfusion bag 100 and covered with an easy-tear paper piece. When the blood transfusion bag 100 is needed for blood transfusion, the easy-tear paper piece is torn off and the silicone plate 520 is adhered to the double-sided adhesive. When the blood transfusion is completed and the blood transfusion bag 100 needs to be removed from the silicone plate 520, the silicone plate 520 can be torn off the outer wall of the blood transfusion bag 100 by existing technical means (such as tearing).

[0045] More preferably, there are multiple first silicone strips 510, each of which is connected to a silicone plate 520. The multiple silicone plates 520 are respectively adhered to different positions on the blood transfusion bag 100 using multiple double-sided adhesive tapes. This allows the blood transfusion bag 100 to be more securely connected to the aforementioned silicone strips 420.

[0046] An optional implementation of this embodiment is as follows: The second connecting part 600 includes a second silicone strip 610 and a clip 620, wherein:

[0047] One end of the second silicone strip 610 is fixed to the outer wall of the middle part of the rubber strip 420 by heat fusion. The first silicone strip 510 is located between the second silicone strip 610 and the plastic shell 400. The clamp 620 is connected to the other end of the second silicone strip 610. The puncture device 320 includes an insertion part 321 and an outwardly convex side wing plate 322 fixed on the outer wall of the insertion part 321. The clamp 620 clamps the outwardly convex side wing plate 322.

[0048] When a blood transfusion bag 100 is needed for a blood transfusion, the puncture device 320 is inserted into the sealing port 120 on the blood transfusion bag 100, and the medical staff then manipulates the clamp 620 to clamp the convex side wing plate 322 of the puncture device 320. The operation is simple and convenient.

[0049] Optionally, the aforementioned clip 620 includes a first clip 621 and a second clip 622 pivotally connected together. A clamping opening is formed between one end of the first clip 621 and one end of the second clip 622. A clearance opening 6211 is provided on the first clip 621 near one end thereon, and a protrusion 6221 is provided on the second clip 622. A through hole 3221 is provided on the outwardly convex side wing plate 322. When the clip 620 clamps the outwardly convex side wing plate 322, the protrusion 6221 passes through the through hole 3221 and is inserted into the clearance opening 6211. Of course, the clip 620 also includes components such as torsion springs, but since the clip 620 is prior art, it will not be described in detail here. This embodiment only uses the clamping function of the existing clip 620. The other end of the aforementioned second silicone strip 610 is connected to the first clip 621 or the second clip 622.

[0050] In this way, the clamp 620 not only clamps the convex side wing plate 322 of the puncture device 320, but also, during clamping, the protrusion 6221 on the clamp 620 inserts into the through hole 3221 of the convex side wing plate 322, thereby more securely connecting the convex side wing plate 322 to the clamp 620. When it is necessary to separate the puncture device 320 from the rubber strip 420, the clamp 620 can be removed from the convex side wing plate 322.

[0051] An optional implementation of this embodiment is as follows: The mounting cavity on the plastic shell 400 extends through the back of the plastic shell 400. A cover plate 440 is also bolted to the back of the plastic shell 400, sealing the opening of the mounting cavity. When the cover plate 440 is removed, it facilitates the installation and removal of the battery 700. When the cover plate 440 is installed, the battery 700 is placed in a relatively sealed environment, thereby protecting the battery 700.

[0052] Optionally, the aforementioned mounting cavity includes a first chamber and a second chamber separated by a partition. The battery 700 is installed in the first chamber, and a control unit 710 is also installed in the second chamber. The battery 700 and its wires are electrically connected to the control unit 710 so as to control the heating temperature of the infusion heating belt 430. Specifically, the control unit 710 may be a circuit board or a chip.

[0053] More preferably, a button 720 and a display 730 are also installed on the front of the plastic casing 400. Both the button 720 and the display 730 are electrically connected to the control unit 710. The button 720 is used to preset the heating temperature of the infusion heating band 430, and the display 730 is used to display the preset heating temperature of the infusion heating band 430. In this way, the heating temperature of the infusion heating band 430 can be preset by the control unit 710 via the button 720 (for example, the control unit 710 controls the amount of current supplied to the infusion heating band 430 by the battery 700 per unit time, thereby controlling the heat generation of the infusion heating band 430), thereby effectively controlling the heating temperature of the infusion tube 300, and thus controlling the temperature of the blood flowing in the infusion tube 300.

[0054] It is worth noting that in this embodiment, a temperature detector with an alarm function (not shown in the figure) can also be connected to the section of the infusion tube 300 near the infusion needle 310. The temperature detector detects the temperature of the infusion tube 300 and issues an alarm when the temperature of the infusion tube 300 is too high (the temperature exceeds the maximum value of the preset temperature threshold) and also issues an alarm when the temperature of the infusion tube 300 is too low (the temperature is lower than the minimum value of the preset temperature threshold).

[0055] It should be noted that the control unit 710 controls the heating temperature of the infusion heating belt 430, the display 730 displays the preset heating temperature, and the temperature detector detects the temperature of the infusion tube 300 and issues an alarm when the temperature is too high or too low. These all utilize existing temperature control technologies, which are commonly used in existing components that can achieve the effect of blood transfusion / infusion temperature control, so they will not be described in detail here.

[0056] The blood transfusion assembly provided in this embodiment, by incorporating the aforementioned control unit 710, button 720, display 730, and temperature detector, can better control the temperature of the blood introduced into the patient's body during transfusion.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
