Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a synchronously inflated tourniquet device for both lower limbs. Background Art

[0002] The tourniquet is made of natural rubber or special rubber, a medical polymer material, and is long, flat, and highly elastic. It can be used to treat bleeding wounds, thereby making the surgical field clear, making it easy to identify various tissues, and facilitating surgical operations. It is suitable for infusion and blood drawing in routine treatment and rescue in medical institutions.

[0003] However, as medical workers continue to explore and improve in clinical practice, the rubber tourniquet has developed into a manual air tourniquet, which can temporarily block the blood supply to the limb, providing a bloodless surgical field for surgery while reducing bleeding.

[0004] In actual use of existing inflatable tourniquets, people will find that the tourniquet is generally tied on one side when in use. If both legs or arms need to be tied, two tourniquets are needed. However, if two tourniquets are needed, it is difficult to control the tourniquets on both sides to achieve consistent pressure on both sides. Utility Model Content

A connecting ring 103 is fixed under the spring 104. The connecting ring 103 is fixed to the exhaust tube 102. A protective cover 7 is sleeved on the outside of the exhaust tube 102, and the protective cover 7 is threadedly connected to the exhaust tube 102. By tying two inflatable bags 3 to the patient's legs or arms and then squeezing the inflatable bags 3, the two pressurization sleeves 5 are inflated at the same time to ensure that the pressures of the two pressurization sleeves 5 are consistent, and the protective cover 7 can be removed from the exhaust tube 102, and the sealing ball 106 can be pressed downward to achieve simultaneous deflation of the two pressurization sleeves 5, so as to quickly perform the second phase scan, namely the full venous phase, and the deep veins and superficial veins can be observed at the same time. The comparison of the two phases can more clearly identify thrombi and illusions.

[0022] Furthermore, a sealing rubber pad is provided in the matching groove 1051 to improve the sealing performance between the sealing ball 106 and the matching groove 1051 .

[0023] Furthermore, a gas cut-off valve 201 is provided on the first connecting pipe 2 , and the connection between the first connecting pipe 2 and the second connecting pipe 4 is controlled by the gas cut-off valve 201 , while preventing the gas backflow of the connecting valve 1 .

[0024] Furthermore, the first connecting tube 2 and the second connecting tube 4 are both made of medical polyvinyl chloride material.

[0025] Furthermore, the sealing ball 106 is provided with a protrusion 1061 , which penetrates the sealing ring 105 , and the protective cover 7 is provided with a groove that cooperates with the protrusion 1061 . The protrusion 1061 can facilitate the staff to press the sealing ball 106 .
