Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a medical filtering three-way valve in three-dimensional form. Background Art

[0002] When performing emergency rescue and before implementing surgical anesthesia, it is necessary to establish infusion channels such as peripheral or central veins. Commonly used infusion pipelines in clinics are infusion sets and blood transfusion sets. Under normal circumstances, precision infusion sets or blood transfusion sets can filter insoluble particles in the liquid medicine or blood input into the patient's body. However, in a large number of clinical actual operations, drugs often need to be intravenously injected or continuously infused using a micro-infusion pump. After installing a conventional three-way valve on the conventional infusion pipeline, the drug just bypasses the filtering device on the infusion set or blood transfusion set, allowing the unfiltered drug to directly enter the human blood vessel. Since a large amount of clinically used drugs for intravenous injection are stored in glass ampoules, the unfiltered drug may contain glass debris, dust, and other insoluble particles generated when breaking the ampoule, resulting in adverse reactions after infusion in patients. In severe cases, it can cause local blood circulation obstruction, leading to organ failure and even endangering the patient's life.

[0003] During the infusion process of the liquid medicine, the DEHP-plasticized PVC material of the infusion pipeline is easily dissolved by the fat-soluble liquid medicine and enters the human body with the liquid medicine. The adsorption effect of DEHP on the drug reduces the actual amount of drug received by the patient, resulting in the inability to achieve the expected therapeutic effect and even bringing safety hazards to the patient. In another emergency situation, the patient needs to be emergently infused with liquid medicine, and conventional filtration will affect the infusion speed and endanger the life of the emergency patient. For this reason, we propose a medical filtering three-way valve in three-dimensional form. Summary of the Invention

It retains the characteristics of the traditional medical three-way valve, such as convenient operation, shortened operation time, reduced labor intensity of the operator, overall enclosure during infusion, prevention of liquid leakage and contamination of the liquid medicine, etc., making it convenient to add medicine temporarily during infusion. And through the filtration mode, solid particles can be filtered out, providing better protection for the life safety of the treated patients, and making up for the defect that the traditional medical three-way valve cannot filter. Moreover, it realizes the rapid conversion between the filtration mode and the non-filtration mode of the medical three-way valve for liquid medicine, and can meet the requirements of rapid infusion and precise filtration infusion on the premise that the liquid medicine is not polluted by the external environment, thus meeting the needs of medical clinics in multiple aspects, making the operation of medical staff more convenient and safer during the treatment of patients. The non-filter layer 15 and the filter layer 16 are made of common medical materials, and the common medical materials are medical plastics, medical glass, or medical stainless steel. The non-filter layer 15 and the filter layer 16 are separated from each other, and the interiors of the non-filter layer 15 and the filter layer 16 are both provided with filter materials that block solid particles and do not affect the flow of liquid. The apertures of the first three-channel tube hole 1, the second three-channel tube hole 2, the third three-channel tube hole 3, and the fourth three-channel tube hole 13 are the same. The apertures of the first on-off controller hole 4, the second on-off controller hole 5, the third on-off controller hole 6, and the fourth on-off controller hole 14 are the same. The apertures of the first adjustable combined filter element hole 7, the second adjustable combined filter element hole 8, the third adjustable combined filter element hole 9, the fourth adjustable combined filter element hole 10, the fifth adjustable combined filter element hole 11, and the sixth adjustable combined filter element hole 12 are the same. The first three-channel tube hole 1, the second three-channel tube hole 2, and the third three-channel tube hole 3 are interconnected, and there is a fourth three-channel tube hole 13 at the intersection. At the same time, the first three-channel tube hole 1 and the second three-channel tube hole 2, and the second three-channel tube hole 2 and the third three-channel tube hole 3 form a 90-degree angle with each other in the horizontal plane. The first on-off controller hole 4, the second on-off controller hole 5, and the third on-off controller hole 6 are interconnected, and there is a fourth on-off controller hole 14 at the intersection. At the same time, the first on-off controller hole 4 and the second on-off controller hole 5, and the second on-off controller hole 5 and the third on-off controller hole 6 form a 90-degree angle with each other in the horizontal plane. And there are three outward-sloping paddles on the upper part of the on-off controller, with a 90-degree angle between them in the horizontal plane. The first adjustable combined filter element hole 7, the second adjustable combined filter element hole 8, and the third adjustable combined filter element hole 9 are interconnected.Moreover, the first adjustable combined filter core hole 7 and the second adjustable combined filter core hole 8, and the second adjustable combined filter core hole 8 and the third adjustable combined filter core hole 9 form a 90-degree angle with each other in the horizontal plane. The fourth adjustable combined filter core hole 10, the fifth adjustable combined filter core hole 11, and the sixth adjustable combined filter core hole 12 are interconnected, and the fourth adjustable combined filter core hole 10 and the fifth adjustable combined filter core hole 11, and the fifth adjustable combined filter core hole 11 and the sixth adjustable combined filter core hole 12 form a 90-degree angle with each other in the horizontal plane.

[0026] In use, the adjustable combined filter element is inserted through the fourth on-off controller hole 14 on the on-off controller and can slide up and down. When the adjustable combined filter element is upward, the first on-off controller hole 4 coincides with the fourth adjustable combined filter element hole 10, the second on-off controller hole 5 coincides with the adjustable combined filter element hole 10, and the third on-off controller hole 6 coincides with the adjustable combined filter element hole 11. When the liquid medicine flows through each hole, the filter material built in the filter layer 16 can block solid particles. When the adjustable combined filter element is downward, the first on-off controller hole 4 coincides with the adjustable combined filter element hole 7, the first on-off controller hole 4 coincides with the adjustable combined filter element hole 8, and the first on-off controller hole 4 coincides with the adjustable combined filter element hole 9. When the liquid medicine flows through each hole and the non-filter layer 15, the liquid medicine passes through quickly without being blocked. The on-off controller is inserted through the fourth three-channel pipe hole 13 on the three-channel pipe and can be rotated horizontally. For example, by rotating the on-off controller and the three-channel pipe, the first three-channel pipe hole 1 can coincide with the first on-off controller hole 4, the second three-channel pipe hole 2 can coincide with the second on-off controller hole 5, and the third three-channel pipe hole 3 can coincide with the third on-off controller hole 6. At this time, the first three-channel pipe hole 1, the second three-channel pipe hole 2, and the third three-channel pipe hole 3 are interconnected, and the liquid medicine can flow freely through the first three-channel pipe hole 1, the second three-channel pipe hole 2, and the third three-channel pipe hole 3. For example, by rotating the on-off controller and the three-channel pipe, the second three-channel pipe hole 2 can coincide with the first on-off controller hole 4, and the third three-channel pipe hole 3 can coincide with the second on-off controller hole 5. The first three-channel pipe hole 1 and the third on-off controller hole 6 are blocked. At this time, the second three-channel pipe hole 2 and the third three-channel pipe hole 3 are interconnected, and the liquid medicine can flow freely through the second three-channel pipe hole 2 and the third three-channel pipe hole 3, blocking the first three-channel pipe hole 1. According to the above operations, by rotating, the first three-channel pipe hole 1 and the second three-channel pipe hole 2 can be interconnected, blocking the third three-channel pipe hole 3, the first three-channel pipe hole 1 and the third three-channel pipe hole 3 can be interconnected, blocking the second three-channel pipe hole 2, the first three-channel pipe hole 1, the second three-channel pipe hole 2, and the third three-channel pipe hole 3 do not coincide with the first on-off controller hole 4, the second on-off controller hole 5, and the third on-off controller hole 6, blocking all of the first three-channel pipe hole 1, the second three-channel pipe hole 2, and the third three-channel pipe hole 3. By sliding the adjustable combined filter element up and down, the rapid conversion between the liquid medicine filtration mode and the non-filtration mode can be achieved. By rotating the on-off controller, the on-off of the liquid medicine flowing through the first three-channel pipe hole 1, the second three-channel pipe hole 2, and the third three-channel pipe hole 2 can be controlled.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
