DETAILED DESCRIPTION

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-5 As shown, this embodiment proposes a device for reducing liquid leakage from a water-light syringe needle, comprising a needle sleeve 1, a connecting tube 2 is installed at the bottom of the needle sleeve 1, a sealing pad 7 is arranged on the top of the needle sleeve 1, an inner liner 3 is arranged on the inner bottom wall of the needle sleeve 1, a plurality of needle tubes 4 are installed on the top of the inner liner 3, a sealing ring plate 5 is installed on the inner wall of the needle sleeve 1, a plurality of needle seats 6 are installed on the top of the sealing ring plate 5, a needle body 8 is installed on one side of the needle seat 6, a needle body 8 is arranged on the inner wall of the needle tube 4 and the top end passes through the needle seat 6, a cavity 9 is provided on the inner wall of the needle body 8, grooves 10 are provided on the inner walls on both sides of the needle body 8, a valve sleeve 11 is provided on the inner wall of the groove 10, and first through holes 12 are provided on both sides of the valve sleeve 11.

[0022] The inner bottom wall of the valve sleeve 11 is provided with a valve core 13, the top sleeve of the valve core 13 is provided with a spring 14, the top of the spring 14 is installed with a valve seat 15, and the inner wall of the valve seat 15 is provided with a second through hole 16. When the device is in use, the staff manually installs the connecting tube 2 connected to the needle sleeve 1 on the water-light syringe, and when injecting through a plurality of needle tubes 4 and the needle body 8 in the needle seat 6, the sealing pad 7 connected to the needle sleeve 1 is attached to the skin of the patient's face and sucked tightly, so that there is no gap between the needle sleeve 1 and the facial skin, so that the water-light syringe needle has a good sealing effect and reduces leakage. At the same time, when the water-light liquid enters the cavity 9 in each needle body 8, the pressure of the water-light liquid in each cavity 9 pushes the valve sleeve 11, so that the valve sleeve 11 is forced to drive the valve core 13 to squeeze the spring 14, so that the valve sleeve 11 moves in the cavity 9 and the groove 10, thereby The top end of the valve sleeve 11 fits on the valve seat 15, so that the water-light liquid in the cavity 9 enters the valve sleeve 11 through the groove 10 and the first through hole 12, so that the water-light liquid in the valve sleeve 11 flows out through the second through hole 16, thereby causing the water-light liquid to flow in one direction. In the absence of external force, the valve sleeve 11 connected to the valve core 13 driven by the rebound force of each spring 14 will remain in the closed position, thereby preventing the water-light liquid from flowing back and realizing one-way flow, thereby reducing leakage of the needle of the water-light syringe. The needle body 8 is provided with a first protrusion 801, a second protrusion 802, a third protrusion 803, a fourth protrusion 804, a fifth protrusion 805, a sixth protrusion 806, a seventh protrusion 807, and an eighth protrusion 808, which has eight force-bearing surfaces and points, greatly reducing the pain of puncture and fitting the skin to avoid leakage of water-light liquid.

[0023] The sealing pad 7 is tightly fitted to the needle sleeve 1. The sealing pad 7 is set as a silicone sealing pad. When injection is performed through a plurality of needle tubes 4 and a needle body 8 in a needle seat 6, the sealing pad 7 connected to the needle sleeve 1 is fitted to the skin of the patient's face and sucked tightly, so that there is no gap between the needle sleeve 1 and the facial skin.

[0024] The needle body 8 is integrated with the cavity 9 and the groove 10 , and the cavity 9 and the groove 10 are communicated with each other. When the water-light liquid enters the cavity 9 in each needle body 8 , the pressure of the water-light liquid in each cavity 9 pushes the valve sleeve 11 .

[0025] The valve sleeve 11 is movably connected to the cavity 9 and the groove 10, and the groove 10 is communicated with the first through hole 12. The valve sleeve 11 is pushed by the pressure of the water-light liquid in each cavity 9, so that the valve sleeve 11 is forced to drive the valve core 13 to squeeze the spring 14, so that the valve sleeve 11 moves in the cavity 9 and the groove 10.

[0026] The needle body 8 includes the needle body 8, a first protrusion 801, a second protrusion 802, a third protrusion 803, a fourth protrusion 804, a fifth protrusion 805, a sixth protrusion 806, a seventh protrusion 807 and an eighth protrusion 808. The first protrusion 801, the second protrusion 802, the third protrusion 803 and the fourth protrusion 804 are arranged in the outer circle, and the fifth protrusion 805, the sixth protrusion 806, the seventh protrusion 807 and the eighth protrusion 808 are arranged in the inner circle.

[0027] The valve core 13 is tightly fitted to the spring 14 and the valve sleeve 11, and the valve seat 15 is fixedly connected to the spring 14 and the inner wall of the valve sleeve 11. The top of the valve sleeve 11 is fitted on the valve seat 15, so that the water-light liquid in the cavity 9 enters the valve sleeve 11 through the groove 10 and the first through hole 12, and then the water-light liquid in the valve sleeve 11 flows out through the second through hole 16.

[0028] The second through hole 16 is communicated with the cavity 9, and the valve seat 15 is integrated with the second through hole 16. The water-light liquid in the valve sleeve 11 flows out through the second through hole 16, thereby achieving unidirectional flow of the water-light liquid.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] When the device for reducing liquid leakage from the needle of an aqua injection syringe is used, a staff member manually installs the connecting tube 2 connected to the needle sleeve 1 on the aqua injection syringe, and when injecting through a plurality of needle tubes 4 and a needle body 8 in a needle seat 6, the sealing pad 7 connected to the needle sleeve 1 is attached to the skin of the patient's face and sucked tightly, so that there is no gap between the needle sleeve 1 and the facial skin, so that the sealing effect of the aqua injection syringe needle is good and liquid leakage is reduced. At the same time, when the aqua liquid enters the cavity 9 in each needle body 8, the pressure of the aqua liquid in each cavity 9 pushes the valve sleeve 11, so that the valve sleeve 11 is forced to drive the valve core 13 to squeeze the spring 14, so that the valve sleeve 11 moves in the cavity 9 and the groove 10, so that the top end of the valve sleeve 11 is attached to the valve seat 15, so that the aqua liquid in the cavity 9 The body enters the valve sleeve 11 through the groove 10 and the first through hole 12, so that the water-light liquid in the valve sleeve 11 flows out through the second through hole 16, thereby causing the water-light liquid to flow in one direction. In the absence of external force, the valve sleeve 11 connected to the valve core 13 driven by the rebound force of each spring 14 will remain in the closed position, thereby preventing the water-light liquid from flowing back and realizing one-way flow, thereby reducing leakage of the water-light syringe needle. The needle body 8 is provided with a first protrusion 801, a second protrusion 802, a third protrusion 803, a fourth protrusion 804, a fifth protrusion 805, a sixth protrusion 806, a seventh protrusion 807, and an eighth protrusion 808, which has eight force-bearing surfaces and points, greatly reducing the pain of puncture and fitting the skin, and avoiding leakage of the water-light liquid.
