Description

Technical Field

[0001] The utility model relates to the technical field of blood transfusion apparatuses, and more specifically, to a Y-shaped blood transfusion apparatus. Background Art

[0002] Pediatric patients are small in weight and the amount of blood products transfused is also small. It is difficult to control the fluid infusion speed with a switch, and the drip pump squeezing the blood transfusion device will destroy the blood products. Currently in clinical practice, we connect a tee to the syringe and combine the corresponding extension tube with the blood bag and the transfusion device. We use a push pump to control the syringe and adjust the speed, and use the tee to turn and adjust the transfusion volume.

[0003] Existing blood transfusion devices need to be assembled manually, which is time-consuming and labor-intensive, and increases the cost of consumables. There is a risk that the assembly interface will fall off during the infusion process. Therefore, how to design a Y-type blood transfusion device has become a problem that we currently need to solve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a Y-type blood transfusion device. By setting a main branch tube and a branch tube, a branch tube is added on the basis of the original blood transfusion device, and the branch tube is integrated with the main branch tube, thereby increasing the sealing effect and eliminating the need for manual assembly, which is more time-saving and labor-saving and can reduce costs to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Y-type blood transfusion device, comprising a main branch, a filter is connected to the top of the main branch, a filter is fixedly installed on the inner wall of the filter, a first needle is fixedly installed on the top of the filter, a first buckle is provided on the outer side of the main branch, a speed regulating switch is slidably connected to the outer side of the main branch, a branch pipe is connected to the outer wall of the main branch, a pump infusion tube connector is fixedly installed on one end of the branch pipe, and an infusion needle is inserted into the inner wall of the pump infusion tube connector.

[0006] In a preferred embodiment, the inner wall of the infusion needle is slidably connected to a liquid pushing assembly, and the outer side of the branch tube is slidably connected to a second buckle.

[0007] In a preferred embodiment, a second needle is fixedly mounted on the bottom end of the main branch, and the first buckle is the same size as the second buckle.

[0008] In a preferred embodiment, the inner diameter and outer diameter of the main branch pipe and the branch pipe are the same.

[0009] In a preferred embodiment, the overall length of the main branch is the same as that of a conventional blood transfusion set.

[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model provides a main branch tube and a branch tube, and adds a branch tube on the basis of the original blood transfusion device, which is convenient to operate during blood transfusion. Since the application is a one-piece device, the cost is reduced, manual assembly is not required, time and labor are saved, and the fully enclosed setting reduces the risk of blood spillage.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Refer to the instruction manual Figure 1-3 ,like Figure 1 As shown, a Y-type blood transfusion set of an embodiment of the utility model comprises a main branch pipe 1, a filter 2 is connected to the top of the main branch pipe 1, a filter net 3 is fixed and supported by the filter 2, a filter net 3 is fixedly installed on the inner wall of the filter 2, and blood is filtered by the filter net 3, a first needle 4 is fixedly installed on the top of the filter 2, and the first needle 4 is connected to the blood bag, as shown in FIG. Figure 3 As shown, a first buckle 5 is provided on the outer side of the main branch 1. By setting the first buckle 5, by pressing the first buckle 5, one end of the first buckle 5 is clamped on the inner side, so that the main branch 1 can be squeezed to stop the blood transportation. The second buckle 11 below is the same. Figure 1As shown, the outer side of the main branch pipe 1 is slidably connected with a speed control switch 6, and the speed of blood transfusion can be controlled by setting the speed control switch 6. The outer wall of the main branch pipe 1 is connected with a branch pipe 7, and one end of the branch pipe 7 is fixedly installed with a pump infusion pipe connector 8, and the inner wall of the pump infusion pipe connector 8 is plugged with an infusion needle 9, and the inner wall of the infusion needle 9 is slidably connected with a liquid pushing component 10, and the outer side of the branch pipe 7 is slidably connected with a second buckle 11, and the bottom end of the main branch pipe 1 is fixedly installed with a second needle 12, the first buckle 5 and the second buckle 11 are the same size, the inner diameter and outer diameter of the main branch pipe 1 and the branch pipe 7 are the same, and the overall length of the main branch pipe 1 is the same as that of a conventional blood transfusion device.

[0018] It should be noted that, a branch tube 7 is added on the basis of the original blood transfusion device. When directly dripping, the first buckle 5 on the outside of the main branch tube 1 is opened, and the second buckle 11 on the outside of the branch tube 7 is closed. The speed can be controlled by adjusting the speed control switch 6. When infusing a non-whole bag, the speed control switch 6 is opened, the first buckle 5 on the outside of the main branch tube 1 is clamped, the second buckle 11 on the outside of the branch tube 7 is opened and the infusion needle 9 is connected. The required dose of blood products can be drawn through the infusion needle 9, and then the speed control switch 6 is closed, the first buckle 5 on the outside of the main branch tube 1 is opened, and the blood transfusion speed of the infusion needle 9 is adjusted by the push pump. It should be noted that the length of the entire blood transfusion device remains unchanged with the original blood transfusion device, the bifurcation is close to the top, and it can be slightly below the filter 2 and the speed control switch 6, and the length below the main branch Y-shaped bifurcation is kept as much as possible, because there is a certain distance between the bedside push pump and the patient's indwelling needle or deep vein. The present application is a one-piece device that reduces costs, does not require manual assembly, saves time and effort, and is a fully enclosed setting that reduces the risk of blood spillage.
