Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-3:
according to the utility model discloses an infusion leather strap anti-drop needle, including syringe needle 1, needle handle 2, needle cover 3, hose 4 and connecting seat 5, 1 rigid coupling of syringe needle in 2 front ends of needle handle, 4 one end rigid couplings of hose in 2 rear ends of needle handle, connecting seat 5 is connected to the 4 other ends of hose, and on syringe needle 1 and needle handle 2 were arranged in to 3 covers of needle cover, needle handle 2 was equipped with rectangle curb plate 21, and this design guarantees that needle cover 3 can cover syringe needle 1 when not using.
The needle sleeve 3 comprises a needle protecting sleeve 31 and a needle handle sleeve 32, the needle protecting sleeve 31 is sleeved on the needle 1 and fixedly connected to the front end of the needle handle sleeve 32, the needle handle sleeve 32 is sleeved on the needle handle 2, and the design enables the needle handle sleeve 32 and the needle handle sleeve 32 to be integrally designed and simultaneously adjustable.
The needle handle sleeve 32 is provided with a needle handle side opening 321 on the side wall, a needle handle clamping groove 322 is arranged on the side edge of the needle handle side opening 321, an elastic clamping piece 323 is arranged at the front end of the needle handle clamping groove 322, the rectangular side plate 21 can be clamped into the needle handle clamping groove 322 by the design, and the elastic clamping piece 323 prevents the rectangular side plate 21 from being separated from the needle handle clamping groove 322.
The rear end of the needle handle sleeve 32 is provided with a circular ring clamping groove 324, the front end of the connecting seat 5 is provided with a circular ring buckle 51, and the whole needle sleeve 3 can be clamped in front of the connecting seat 5 during infusion to prevent the needle sleeve 3 from sliding.
The side wall of the needle head protecting sleeve 31 is provided with a sliding opening 311 which is through back and forth, the sliding opening 311 is connected with the needle handle side opening 321 and has the same width, and the design ensures that the rectangular side plate 21 can slide through the sliding opening 311.
The length of the needle handle clamping groove 322 is 0.5-1mm longer than the width of the rectangular side plate 21; when the transfusion is not needed, the needle handle clamping groove 322 of the needle sleeve 3 can be clamped and embedded on the rectangular side plate 21, so that the needle sleeve 3 is prevented from sliding off.
The inner diameter of the needle protecting sleeve 31 is the same as that of the needle handle sleeve 32, and the inner diameter of the needle protecting sleeve 31 is larger than the outer diameter of the hose 4, so that the needle sleeve 3 can slide on the outer layer of the hose 4.
The needle protecting sleeve 31 and the needle handle sleeve 32 are made of PP or PE materials, so that the needle sleeve 3 has certain elasticity and is convenient to clamp the circular ring buckle 51 and the needle handle clamping groove 322.
In the specific use process, when the infusion needle is not used, the rectangular side plate 21 of the needle handle 2 is clamped and embedded in the needle handle clamping groove 322, and the elastic clamping piece 323 can prevent the rectangular side plate 21 from moving to the needle handle side port 321 in the transportation process and the like, so that the needle sleeve 3 always covers the needle head 1.
When the infusion needle is needed for infusion, the needle handle sleeve 32 can be rotated by force. The rectangular side plate 21 can be rotated to the needle handle side opening 321 due to the elasticity of the elastic clamping piece 323. Because the needle handle side port 321 is communicated with the sliding port 311, the whole needle sleeve 3 can slide to the hose 4 along the rectangular side plate 21, and meanwhile, the whole inner diameter of the needle sleeve 3 is larger than the outer diameter of the hose 4, so the needle sleeve 3 can freely slide to the front of the connecting seat 5 on the outer layer of the hose 4, and the circular ring buckle 51 is clamped by the circular ring clamping groove 324 of the needle handle sleeve 32, thereby preventing the needle sleeve 3 from randomly sliding to influence the transfusion effect during transfusion.
When the transfusion is finished, the needle sleeve 3 can be taken down from the circular ring buckle 51 and sleeved into the needle 1 and the needle handle 2 again, the needle handle sleeve 32 is rotated, the rectangular side plate 21 is embedded into the needle handle clamping groove 322, and the whole needle sleeve 3 is fixed, so that the needle 1 is covered by the needle sleeve 3 again, and the medical staff is prevented from being punctured.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, similar modifications and improvements can be made without departing from the inventive concept of the present invention, and these are also considered to be within the protection of the present invention.
