All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
Referring to fig. 1 and 2, a first embodiment of the present utility model provides a blood sampling needle holder, which includes a protective sleeve 1 having a hollow interior and an open right end, wherein a blood sampling needle head 2 is disposed at the right end of the protective sleeve 1, a connector 3 is disposed at the right end of the blood sampling needle head 2, and the outer diameter of the connector 3 is the same as the inner diameter of the protective sleeve 1;
The right end of the connector 3 is connected with a plastic pipe 4, the right end of the plastic pipe 4 is connected with a rubber hose 5, a spring baffle 6 is arranged on the periphery of the outer surface of the middle section of the plastic pipe 4, and the outer surface of the plastic pipe 4 is wrapped with a needle head protective sleeve 7 with two open ends; the diameter of the inner wall of the opening at the right end of the needle head protective sleeve 7 is the same as that of the outer wall of the plastic pipe 4, and the opening at the left end of the needle head protective sleeve 7 is in insertion fit with the connector 3;
The utility model discloses a syringe needle protecting cover, including plastic tubing, syringe needle protecting cover, spring shielding piece 6, syringe needle protecting cover 7, the surface a week that just is located plastic tubing 4 is provided with spring 8, needle protecting cover 7 both sides are opened and are provided with spout 9, both ends are opened about spout 9 and are provided with draw-in groove 10, the spring shielding piece 6 outside is provided with plastics shell fragment 11, be provided with fixture block 12 in the middle of the plastics shell fragment 11, fixture block 12 and draw-in groove 10 inserts the cooperation, rubber hose 5 right-hand member is provided with output syringe needle 14, output syringe needle 14 left end surface a week is provided with inside cavity and right-hand member open-ended sleeve 15, sleeve 15 is longer than output syringe needle 14, needle protecting cover 7 both sides and be located spout 9 left end and be provided with syringe needle handle 16 (see fig. 3-5 for specific structure details).
Before blood collection, the spring 8 is squeezed between the needle protecting sleeve 7 and the spring retainer 6, the spring 8 is in the compression device, and the clamping block 12 is arranged in the clamping groove 10 at the left end.
The needle protection sleeve 7 is limited, the protection sleeve 1 is taken down, the blood taking needle 2 is pricked into a blood vessel, blood enters the output needle 14 through the plastic tube 4 and the rubber hose 5, the vacuum tube is inserted into the output needle 14 in the needle holder 15, and the blood is sucked out of the output needle 14 and enters the vacuum tube due to the small air pressure in the vacuum tube.
After blood collection is completed, the plastic spring pieces 11 on the two sides are pressed, the plastic spring pieces 10 are bent down, and meanwhile the clamping blocks 12 fall off from the clamping grooves 10. Because the positions of the spring baffle plates 6 are relatively fixed, the spring 8 can push the needle protection sleeve 7 forwards, and at the moment, the inside of the sliding grooves 9 at the two sides of the needle protection sleeve 7 is limited by the plastic elastic sheets 11 for angles, so that the needle protection sleeve 7 can only pop up along the track set by the sliding grooves 9; after the needle protection sleeve 7 is ejected to the tail end, the plastic elastic sheet 11 is loosened, the clamping block 12 can enter the inside of the right end of the clamping groove 10, and at the moment, the needle protection sleeve 7 is sunk into the clamping groove 10 due to the clamping block 12; at this time, the needle protection sleeve 7 is pushed, the needle protection sleeve 7 can be blocked by the clamping block 12 and cannot be pushed, so that the blood taking needle 2 is positioned in the needle protection sleeve 7, the blood taking needle 2 is prevented from being exposed, and the needle protection sleeve 7 can be retracted only when the plastic elastic pieces 11 on the two sides are pressed down again.
Referring to fig. 3 and 5, in a specific technical solution of the embodiment of the present utility model, the end of the plastic elastic sheet 11 is provided with a circular arc-shaped pressing plate 13.
When the needle protection sleeve 7 is to be adjusted, the comfort level of the plastic elastic sheet 11 is poor, and the arc-shaped pressing plate 13 is arranged at the tail end to facilitate the pressing of the plastic elastic sheet 11, and meanwhile, the comfort level during pressing can be improved.
In the specific technical solution of the embodiment of the present utility model, as shown in fig. 2, a sleeve baffle 21 is disposed on a circumference of the outer surfaces of the left and right ends of the sleeve 15.
When the vacuum tube is inserted into the output needle 14, since one hand is required to stabilize the blood taking needle 2, the process requires one hand to operate, while several fingers pinch the sleeve 15, other fingers press the vacuum tube onto the output needle 14, the operation is inconvenient, after the sleeve baffle 21 is added, the fingers are lapped on the sleeve baffle 21 at the right end to press the vacuum tube easily, and when the vacuum tube is removed, the sleeve baffle 21 at the left end can also provide a blocking force for the fingers.
In a specific embodiment of the present utility model, as shown in fig. 2, a frosted protrusion is disposed on the outer surface of the sleeve 14.
The outer surface of the sleeve 14 is provided with sanding protrusions to increase friction on the hand during insertion of the vacuum tube.
In the specific technical scheme of the embodiment of the utility model, as shown in fig. 1-2, a chamfer is formed at the opening of the right end of the protective sleeve 1.
When the production of the blood taking needle holder is carried out, the protective sleeve 1 is sleeved on the outer side of the blood taking needle head 2, the inner diameter of the protective sleeve 1 is almost the same as the diameter of the base of the blood taking needle head 2 in order to prevent the protective sleeve 1 from falling, the base of the blood taking needle head 2 is difficult to align when the protective sleeve 1 is sleeved, the right end opening of the protective sleeve 1 is provided with a chamfer, the base of the blood taking needle head 2 does not need to be aligned, and the protective sleeve 1 can be sleeved only by being approximately aligned.
In the specific technical solution of the embodiment of the present utility model, as shown in fig. 3-4, the left end and the right end of the sleeve 15 form an oblique angle of 15 ° -20 °.
The left end and the right end of the sleeve 15 form an oblique angle of 15-20 degrees, when the vacuum tube is inserted, the position is easily found because the diameter of the opening of the right end is far larger than that of the vacuum tube, and when the vacuum tube is inserted inwards, the position is inaccurately adjusted to be normal by the oblique angle.
In the embodiment of the present utility model shown in fig. 3-4, rubber pads are attached to the upper and lower surfaces of the needle handle 16.
When blood collection is performed, the needle handle 16 is required to be pinched to insert the blood collection needle 2 into a blood vessel, and a rubber pad is attached to the upper surface and the lower surface of the needle handle 16, so that friction force can be increased.
In summary, the needle protecting sleeve 7 is added to the blood sampling needle holder, after blood sampling is completed, the pressing plates 13 on two sides are directly pressed, and the needle protecting sleeve 7 can be ejected out by the internal spring 8 to block the blood sampling needle 2.
