Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, there will now be described in detail, with reference to the accompanying drawings, a non-limiting detailed description of the present invention.
As shown in fig. 1 to 5, the disposable maxillary sinus puncture flushing device of the present embodiment comprises a liquid container 1, a syringe 2, a liquid extracting tube 3, a liquid transporting tube 4, a three-way device 5 and a puncture needle 6, wherein the liquid extracting tube 3 is communicated between a first port 51 of the liquid container 1 and the three-way device 5, the syringe 2 is communicated with a second port 52 of the three-way device 5, the liquid transporting tube 4 is communicated between the puncture needle 6 and a third port 53 of the three-way device 5, a first one-way valve 7 is arranged in the first port 51, and the first one-way valve 7 is communicated from the liquid container 1 to the syringe 2; a second one-way valve 8 is arranged in the third port 53, and the conduction direction of the second one-way valve 8 is from the injector 2 to the puncture needle 6.
The first check valve 7 and the second check valve 8 respectively comprise a valve body 9, a partition plate 10 and a valve membrane 11, wherein the valve body 9 is in a hollow cylindrical shape. The partition plate 10 is fixedly arranged in the valve body 9 along the axial direction of the valve body 9, a connecting hole 101 is formed in the center of the partition plate 10, two liquid through holes 102 are symmetrically formed in the periphery of the connecting hole 101, and the two liquid through holes 102 are circular arc-shaped. The valve membrane 11 is disposed on one side of the partition plate 10, and includes a connection handle 111 fixedly connected in the connection hole 101, and two membranes 112 respectively covering the two liquid through holes 102. The two diaphragms 112 are provided with plug bodies 113, the plug bodies 113 are arc-shaped and movably cover the liquid through holes 102, and the two diaphragms 112 are made of elastic materials and have elasticity.
The first non return valve 7 and the second non return valve 8 work on the same principle.
Taking the first check valve 7 as an example, when the first check valve 7 is in the closed state, the pressure at one end of the connecting handle 111 must be smaller than the pressure at one side of the valve membrane 11, the valve membrane 11 will seal the liquid through hole 102, and the liquid or gas at one side of the valve membrane 11 cannot reach one end of the connecting handle 111 through the liquid through hole 102, and the first check valve 7 is in the closed state.
When the first check valve 7 is in the open state, the pressure on the side of the connecting handle 111 must be greater than the pressure on the side of the valve membrane 11, and at this time, the liquid or gas on the end of the connecting handle 111 can pass through the liquid through hole 102 to the membrane 112, and because the resistance of the membrane 112 is small, the liquid or gas can push the membrane 112 open, so that the liquid or gas can reach the side of the valve membrane 11, and at this time, the first check valve 7 is in the conducting state.
Procedure of the first check valve 7 from opening to closing: when the flow rate of the gas or the liquid is small, the force received by the diaphragm 112 is smaller and smaller, the diaphragm 112 recovers under the action of the self-resilience force, gradually clings to the valve body 9, the plug body 113 is covered in the liquid through hole 102, and the first check valve 7 is closed.
The working principle of the second non return valve 8 is as described above.
The first check valve 7 and the second check valve 8 further comprise a protection plate 12; the protection plate 12 is fixedly arranged in the valve body 9 along the axial direction of the valve body 9, and the protection plate 12 is arranged below the partition plate 10; the shielding plate 12 is provided with a plurality of via holes 121. The protection plate 12 can prevent the membrane 112 from being excessively distorted and deformed and not restored to an original state when being pressed by liquid or gas.
In summary, in the present embodiment, the connecting stem 111 of the first check valve 7 faces the first through opening 51, and the connecting stem 111 of the second check valve 8 faces away from the third through opening 53. In the starting state, the first check valve 7 and the second check valve 8 are both in the closed state due to the absence of pressure; when the medical staff draws liquid, the pressure on the side of the connecting handle 111 of the first one-way valve 7 is greater than the pressure on the side of the valve membrane 11, and the pressure on the side of the connecting handle 111 of the second one-way valve 8 is less than the pressure on the side of the valve membrane 11, so that the first one-way valve 7 is conducted and the second one-way valve 8 is in a closed state, and at the moment, the syringe 2 can draw washing liquid; when the medical staff transfuses, the pressure of the one end of the connecting handle 111 of the first one-way valve 7 is smaller than the pressure of one side of the valve membrane 11, and the pressure of the one end of the connecting handle 111 of the second one-way valve 8 is larger than the pressure of one side of the valve membrane 11, so that the first one-way valve 7 is in a closed state and the second one-way valve 8 is conducted, and at the moment, the injector 2 can convey the flushing liquid to the maxillary sinus of the patient. Therefore, compare in prior art, do not need artifical manual regulation liquid flow direction, have labour saving and time saving's advantage.
It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention.
