Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a heating pipeline for infusion and blood transfusion. Background Art

[0002] Currently in clinical practice, some surgeries or nursing procedures require warming of blood transfusions or infused blood, for example, large-scale rapid blood transfusions, blood exchanges, the presence of clinically significant cold agglutinins in the patient's body, and large temperature differences between the drug solution and the human body.

[0003] Common heating methods in the prior art include water bath heating, or placing the blood bag or infusion bag in a special heating device for heating. The heating effect of these common heating methods is not good enough, and it cannot ensure that the blood or liquid medicine can maintain the required target temperature when it is finally delivered to the patient. If too high a temperature is used for heating, it may cause changes in certain components in the liquid medicine or blood. In addition, there are also some blood transfusion and infusion pipelines that can be heated and portable heaters that can heat the pipelines. For example, a patent application with publication number CN219398482U discloses a disposable blood transfusion device, which is actually a pipeline with a heating function. A number of small heating tubes are arranged in the wall interlayer of the pipeline structure. However, this structure is too complicated and difficult to manufacture. Its production cost is high, and once a fault such as damage occurs, it cannot be discovered in the first time, which will likely have an adverse effect on blood transfusion and infusion. Therefore, this heating pipeline is not suitable for popular use on the market. A patent application with publication number CN115998991A discloses a lightweight online rapid blood transfusion and infusion warmer. When in actual use, the warmer body needs to be firmly fixed on the patient's arm. Although such a warmer is convenient, its application range is not universal. Many patients' physical conditions are not suitable for tying a warmer firmly on their hands, which will cause a burden on their physical recovery.

[0004] In view of the disadvantages of the above-mentioned heating pipeline, such as complex structure and high cost, inconvenient use of the heater, and difficulty in making the liquid reach the required infusion temperature using conventional heating methods, the present invention is to develop an infusion and blood transfusion heating pipeline with a completely new structure.

[0022] The output end of the three-way pipe interface 3 is connected to the input end of the drip filter 4 through a pipeline. The connecting pipeline between the output end of the three-way pipe interface 3 and the input end of the drip filter 4 is a detachable two-section pipeline, which is matched and connected by a first Luer male connector 20 and a first Luer female connector 21, and a third stop clamp 16 is provided on the section of the pipeline connected to the drip filter 4.

[0023] The output end of the drip filter 4 is connected to the input end of the liquid heating box through a pipeline, and the first flow regulator 10 is arranged on the connecting pipeline between the drip filter 4 and the liquid heating box 5. The connecting pipeline between the drip filter 4 and the liquid heating box 5 is a detachable two-section pipeline, and the two sections of the pipeline are connected by the second Luer male head 22 and the second Luer female head 23. A fourth stop clamp 17 is arranged on the section of the pipeline connected to the liquid heating box. The flow regulator 10 is arranged on the section of the pipeline connected to the drip filter 4.

[0024] The liquid heating box 5 has a box structure 51, and the outer dimensions of the box structure 51 are set to match the size of the heating tank that can be placed in the commercially available blood transfusion and infusion warming instrument. A curved pipeline channel 52 is provided inside the box structure 51, and the inner diameter of the curved pipeline channel 52 is larger than the inner diameter of the external infusion pipeline 7. The pipeline 7a connecting the input end of the liquid heating box 5 and the pipeline 7b connecting the output end are respectively connected and fixed to the two ends of the curved pipeline channel 52, that is, the pipelines 7a, 7b and the liquid heating box 5 are connected as a whole after production and manufacturing, and cannot be disassembled. After the liquid heating box 5 cooperates with the blood transfusion and infusion warming instrument, after the warming instrument is powered on, the liquid heating box 5 can be heated to heat the blood or liquid medicine inside. In addition, a gripping hole 53 is also provided on the box structure 51 to facilitate the user's gripping operation.

[0025] The output end of the liquid heating box 5 passes through the pipeline exhaust valve 8. The exhaust valve 8 is connected to the injection piece 9 through a pipeline, and the second flow regulator 11 is arranged on the connecting pipeline between the exhaust valve 8 and the injection piece 9.

Since the inner diameter of the pipeline in the box body is large and it is a curved pipeline channel, the overall heating area is large, and the liquid heating box 5 is arranged at a position closer to the infusion end, so the heat loss is small when the blood or liquid medicine reaches the patient, and the required temperature of the infusion can be well met. In addition, during the high-speed infusion process, bubbles may appear in the pipeline, and the bubbles will be automatically discharged when flowing through the exhaust valve 8, so that the liquid is infused to the patient through the pipeline. Several stop clamps in the pipeline can be pressed to stop the infusion at any time during the infusion process, and two flow regulators can adjust the size of the liquid flow during the infusion process. The injection piece 9 is used to add liquid medicine to the patient during the infusion process.
