Description

Technical Field

[0001] The utility model relates to the technical field of blood transfusion apparatuses, in particular to a combined blood transfusion apparatus. Background Art

[0002] A blood transfusion device is an infusion device that establishes a pathway between blood and veins. It consists of a bottle insertion needle, an air inlet needle or air inlet hole, a needle cap, a dropper, a pipeline, a flow regulating switch, an intravenous needle or an injection needle. When using the blood transfusion device, it needs to be connected to the blood bag, and then the needle on the blood transfusion device is used to deliver blood to the user's body. After the transfusion is completed, the blood transfusion device needs to be recovered.

[0003] However, the existing blood transfusion device is inconvenient to use and has weak functions. When the blood transfusion device is connected to the blood transfusion bag, it is difficult to ensure that the bottle needle is positioned in the blood transfusion bag, and it is difficult to fix the blood transfusion device and the blood transfusion bag, which may cause the blood transfusion device to fall off. In addition, the existing blood transfusion device has poor practicality. When in use, the blood transfusion device may have local parts damaged during transportation. At the same time, it is difficult to recycle the used blood transfusion device, resulting in the entire blood transfusion device being recycled when it is damaged. At the same time, the needle may cause harm to the user during the recycling process. Utility Model Content

A second connecting component 7 is provided at the bottom end of the dropper 1. A protective component 8 is provided at the bottom end of the surface of the second connecting component 7.

[0023] In this embodiment, preferably, the first connecting assembly 2 includes a first connecting tube 201, the bottom end of the first connecting tube 201 is connected to the top end of the dropper 1, the top end of the first connecting tube 201 is connected to the first connecting ring 202, the top end of the first connecting ring 202 is threadedly connected to the second connecting ring 203, and the top end of the second connecting ring 203 is connected to the bottom end of the Y-shaped tube 3;

[0024] Specifically, first open the sealed bag and inspect the entire device. If any parts are found to be damaged, the Y-shaped tube 3 can be replaced using the first connecting tube 201, the first connecting ring 202, and the second connecting ring 203.

[0025] It is understandable that the first connecting ring 202 on the first connecting tube 201 and the second connecting ring 203 under the Y-shaped tube 3 can be replaced during use. After the replacement is completed, the first gasket on the first connecting tube 201 is squeezed and deformed, thereby preventing leakage between the first connecting ring 202 and the second connecting ring 203.

[0026] In this embodiment, preferably, the fixing assembly 6 includes a fixing frame 601, the bottom end of the fixing frame 601 is fixedly connected to the edge of the top end of the thickened tube 4, and both sides of the surface of the fixing frame 601 are fixedly connected to hollow columns 602, one end of the hollow column 602 is threadedly connected to a fixing bolt 603, one end of the fixing bolt 603 is fixedly connected to a telescopic spring 604, and one end of the telescopic spring 604 is fixedly connected to a fixing block 605;

[0027] Specifically, the insertion needle 5 in the fixing frame 601 is inserted into the bottle mouth of the blood bag. During the insertion process, the bottle mouth of the blood bag exerts pressure on the fixing block 605 in the fixing frame 601, causing the fixing block 605 to squeeze the telescopic spring 604. When the bottle mouth of the blood bag is in a suitable position in the fixing frame 601, the telescopic spring 604 rebounds and resets the fixing block 605. Then, the fixing bolts 603 in the hollow columns 602 on both sides of the fixing frame 601 are rotated to allow the fixing bolts 603 to drive the telescopic spring 604 and the fixing block 605 to move, so that the fixing block 605 is close to the bottle mouth of the blood bag, fixing the bottle mouth of the blood bag in the fixing frame 601, and preventing the insertion needle 5 from puncturing the blood bag.

[0028] It can be understood that the fixing bolt 603 is used to control the position of the fixing block 605 on the telescopic spring 604 in the fixing frame 601, and the fixing block 605 is allowed to squeeze the telescopic spring 604, and the telescopic spring 604 rebounds to reset the fixing block 605, thereby reducing the difficulty of operation.

[0029] In this embodiment, preferably, the second connecting assembly 7 includes a second connecting tube 701, the top end of the second connecting tube 701 is connected to the bottom end of the dropper 1, the bottom end of the second connecting tube 701 is connected to a third connecting ring 702, and the top end of the third connecting ring 702 is threadedly connected to a needle 703;

[0030] Specifically, the needle 703 can be replaced by utilizing the cooperation between the second connecting tube 701 and the third connecting ring 702;

[0031] It is understandable that when a part is damaged, the needle 703 can be replaced using the third connecting ring 702 on the second connecting tube 701. After the replacement is completed, the second gasket on the third connecting ring 702 is squeezed and deformed, thereby preventing leakage between the third connecting ring 702 and the needle 703.

[0032] In this embodiment, preferably, the protection assembly 8 includes a protection frame 801, the bottom end of the protection frame 801 is fixedly connected to the bottom end of the surface of the needle 703, and both sides of the protection frame 801 are provided with limiting holes. The inner portion of the limiting hole is slidably connected to a protection column 802, and the middle portion of the top of the protection column 802 is fixedly connected to a rubber pad 803;

[0033] Specifically, after use, the protective column 802 in the protective frame 801 can be rotated and lifted to a suitable height so that the height of the rubber pad 803 is higher than the needle 703, and then the protective column 802 is rotated to fix the position between the protective frame 801 and the protective column 802, and the needle 703 is retracted into the protective column 802;

[0034] It can be understood that the friction pad on the protection column 802 is used to increase the friction between the protection column 802 and the protection frame 801, and then the position of the protection column 802 in the protection frame 801 is fixed by rotating the protection column 802;

[0035] In this embodiment, preferably, a groove is provided on one side of the surface of the dropper 1, and a scale bar is attached to the inside of the groove.

[0036] When using a combined blood transfusion device of this embodiment, first open the sealed bag and check the entire device. If any local parts are found to be damaged, the parts of the device can be replaced by using the cooperation between the first connecting tube 201, the first connecting ring 202, the second connecting ring 203, the second connecting tube 701, and the third connecting ring 702. Then, the bottle insertion needle 5 in the fixing frame 601 is inserted into the bottle mouth of the blood bag. During the insertion process, the bottle mouth of the blood bag will apply pressure to the fixing block 605 in the fixing frame 601, so that the fixing block 605 squeezes the telescopic spring 604. When the bottle mouth of the blood bag is in a suitable position in the fixing frame 601, the telescopic spring 604 The rebound resets the fixing block 605, and then the fixing bolts 603 in the hollow columns 602 on both sides of the fixing frame 601 are rotated to allow the fixing bolts 603 to drive the telescopic spring 604 and the fixing block 605 to move, so that the fixing block 605 is close to the blood bag bottle mouth, and the blood bag bottle mouth is fixed in the fixing frame 601 to prevent the bottle insertion needle 5 from puncturing the blood bag. After use, the protective column 802 in the protective frame 801 can be rotated and lifted to a suitable height, so that the height of the rubber pad 803 is higher than the needle 703, and then the protective column 802 is rotated to fix the position between the protective frame 801 and the protective column 802, and the needle 703 is retracted into the protective column 802.
