Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, the utility model relates to a multi-channel infusion filter connecting tube. Background Technique

[0002] It is known that a multi-channel infusion filter connecting tube is a medical device widely used in the medical field. Its multi-channel design can connect multiple infusion channels simultaneously, enabling medical staff to conveniently infuse multiple drugs or liquids for patients at the same time, such as antibiotics, nutrient solutions, electrolyte solutions, etc. This design greatly reduces the frequency of replacing infusion tubes, improves infusion efficiency and nursing efficiency, and reduces the pain of repeated punctures for patients; the built-in filtering device can effectively remove particulate impurities in the infusion, such as dust, bacteria, drug crystals, etc., ensuring that the liquid infused into the patient's body is pure and free of impurities, thereby reducing the risk of infection and ensuring the patient's life safety; among them, in the ICU intensive care unit, patients often need to receive multiple drug treatments, so the use of a multi-channel infusion filter connecting tube can greatly facilitate the work of medical staff and improve treatment efficiency.

[0003] Among them, the existing multi-channel infusion filter connecting tube lacks measures to discharge air bubbles, and there are air bubbles remaining in the transported liquid medicine. If a large number of air bubbles enter the human body in a short time, up to 5 to 10 milliliters or more, the air bubbles may enter the pulmonary artery, causing pulmonary embolism complications, and may further lead to symptoms such as dyspnea, chest pain, restlessness, etc., and may even endanger life; if a large number of air bubbles enter the human body, it will also stimulate the heart and affect the normal contraction and ejection function of the heart, thus posing a danger to physical health; therefore, before infusion with the existing multi-channel infusion filter connecting tube, medical staff need to check in time to ensure that there is no air leakage or air bubbles; during the infusion process, if air bubbles are found in the infusion tube, they will be removed in time to avoid air bubbles entering the human body.

[0004] However, in actual use, the existing multi-channel infusion filter connecting tube has the following problems:

[0005] 1. If each use of the multi-channel infusion filter connecting tube requires medical staff to frequently check the amount of air bubbles during the infusion process, the workload of this device will increase;

[0006] 2. Since the multi-channel infusion filter connecting tube transports a large amount of drugs, if the same multi-channel infusion filter connecting tube is used for a long time, due to the lack of measures to detect the filtering part, the filtering part will be blocked by various impurities, thereby affecting the actual infusion speed and the treatment of patients, and it is difficult for medical staff to detect; if it is replaced at a specified time or according to the infusion quantity, the cost will increase and there is still a risk of blockage.

[0007] Therefore, a multi-channel infusion filtration connecting tube is proposed as a further improvement. Summary of the Utility Model

[0008] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present utility model provides a multi-channel infusion filtration connecting tube to solve the problems raised in the above-mentioned background technology.

[0009] To achieve the above object, the present utility model provides the following technical solution: A multi-channel infusion filtration connecting tube, the multi-channel infusion filtration connecting tube includes: an infusion cavity, a filter membrane and a gas collection cavity;

[0010] The gas collection cavity is fixedly installed on the top of the infusion cavity, and the inside of the gas collection cavity is communicated with the inside of the infusion cavity. The edge of the filter membrane is fixedly connected to the inner wall of the infusion cavity;

[0011] A plurality of uniformly distributed infusion inlet connectors are fixedly installed on one side of the infusion cavity, and the infusion inlet connectors are located between the filter membrane and the bottom of the infusion cavity;

[0012] An infusion outlet connector is fixedly installed on the other side of the infusion cavity, and the infusion outlet connector is located between the filter membrane and the gas collection cavity;

[0013] A one-way valve for guiding the liquid medicine to flow into the inside of the infusion cavity is fixedly installed inside the infusion inlet connector.

[0014] Further, the color of the filter membrane is set to be dark.

[0015] Further, the material of the multi-channel infusion filtration connecting tube is set to be an elastic 100% transparent material.

[0016] Further, an extension tube is fixedly installed at one end of the infusion outlet connector away from the multi-channel infusion filtration connecting tube.

[0017] Further, the shape of the top of the multi-channel infusion filtration connecting tube is set to be semi-elliptical or semi-circular.

[0018] Further, a sticker for sticking to the hospital gown or the patient's skin is fixedly installed on the bottom surface of the multi-channel infusion filtration connecting tube.

[0019] Further, the volume of the gas collection cavity is at least greater than 5 ml.

[0020] The technical effects and advantages of the present utility model:

[0021] 1. Compared with the prior art, by providing an infusion cavity, a filter membrane, and a gas collection cavity, the design of the gas collection cavity at the top of the infusion cavity facilitates the residual bubbles in the infusion to slide into the gas collection cavity. Thus, medical staff can observe the accumulated amount of bubbles in the gas collection cavity in a timely manner and then take corresponding measures to prevent the bubbles from entering the human body. The filter membrane filters impurities in the medicine and improves the safety of infusion.

[0022] 2. Compared with the prior art, by setting the color of the filter membrane to a dark color, the filter membrane can be distinguished from the impurities in the liquid medicine, making it easier for medical staff to detect. By using a transparent material, it is convenient to observe the air content and impurity content in the multi-channel infusion filter connecting tube. By providing an extension tube, the movement of the multi-channel infusion filter connecting tube is reduced. By providing an adhesive patch, the multi-channel infusion filter connecting tube moves synchronously with the patient, reducing additional hand-held operations and improving the convenience of transportation.
