Abstract
The utility model discloses a disposable lancet with the depth adjustable. An elastic caliper is installed at the upper end of an outer sleeve, an adjusting hole is arranged on the surface of the upper end of the elastic caliper, an adjusting knob is installed on the adjusting hole, a screw at the lower end of the adjusting knob is matched with a nut at the upper end of an adjusting block, the lower end of adjusting block is connected with the upper end of an ejection spring, the lower end of the ejection spring is connected with the upper end of a lancet body, a protrusion is arranged on the outer surface of the upper portion of the lancet body, the lower end of the protrusion on the lancet body is clamped on a clamping protrusion on the lower portion inside the elastic caliper, an expanding block is arranged on a lower opening of the outer sleeve, the upper surface of the expanding block is an arc-shaped protrusion which is high in the middle and low on two sides, a through-hole is arranged at the center of the expanding block, the outer edge of the through-hole of the upper surface of the expanding block is located at the inner end of a clamping opening of the lowest end of the elastic caliper, and the protrusion of the lower surface of the expanding block is arranged outside the lower end opening of the outer sleeve. The puncturing depth can be adjusted according to thicknesses of different skins, thus, one specification can meet the requirements for blood sampling of all persons with different skin thicknesses, and storage of different specifications of disposable lancets can be saved.
Description
Technical field
This utility model belongs to medical blood count utensil, particularly a kind of disposable lancet of adjustable-depth.
Background technology
Disposable lancet is used in present medical blood count, because different Person's skin thickness difference and the difference that needs blood volume, therefore in order to adapt to the needs that different skin thickness and blood volume are arranged, the disposable lancet that different acupuncture depth gauge lattice must be arranged, different with the need blood volume with the skin thickness that is applicable to different people.Therefore the lancet of a lot of specifications need to be prepared by hospital.With having the useful life, because the lancet of preparing different size not necessarily can use, cause waste due to disposable medical.
The utility model content
Technical problem to be solved in the utility model is: the disposable lancet that a kind of adjustable-depth is provided.Can according to the thickness of different skin and the requirement of blood volume, regulate during use.
The technical solution of the utility model is:
a kind of disposable lancet of adjustable-depth, it is characterized in that: an overcoat, the elasticity clamp are equipped with in outer set upper side, elasticity clamp upper end face has adjustment hole, adjusting knob is housed on adjustment hole, the screw rod of adjusting knob lower end stretches into inside, elasticity clamp upper end, in inside, elasticity clamp upper end, regulating block is arranged, the screw rod of adjusting knob lower end coordinates with the spiral shell button of regulating block upper end, the regulating block lower end connects the upper end of ejection-spring, the lower end of ejection-spring is connected to the upper end of lancet, on the lancet outer surface of upper, projection is arranged, protruding lower end on lancet is stuck on the card convex of bottom in the elasticity clamp, end opening at overcoat, the expansion piece that can slide up and down is housed, the upper surface of expansion piece is the low arc convex in middle high both sides, there is a through hole in expansion piece central authorities, through-hole diameter is greater than the full-size of lancet outer surface, it is inner that the through hole outer rim of expansion piece upper surface is placed in elasticity clamp bayonet socket bottom, expansion piece lower surface is given prominence to outside the overcoat lower port.
There is the spacing block of regulating block at the middle part in the elasticity clamp.
This utility model effect is:
Because the disposable lancet of adjustable-depth can according to the thickness of different skin, be regulated when blood sampling is used.Therefore a kind of specification people that can satisfy the thickness of all different skin use of taking a blood sample.Therefore can save the deposit of different size disposable lancet.
Description of drawings
Fig. 1 is the structural representation of the disposable lancet of adjustable-depth.
In figure: the block at middle part in the card convex of bottom, the projection on 9 lancet outer surface of upper, 10 elasticity clamp in 1 adjusting knob, 2 regulating blocks, 3 overcoats, 4 ejection-springs, 5 elasticity clamp, 6 lancets, 7 expansion pieces, 8 elasticity clamp.
The specific embodiment
the disposable lancet of a kind of adjustable-depth as shown in the figure, an overcoat, the elasticity clamp are equipped with in outer set upper side, elasticity clamp upper end face has adjustment hole, adjusting knob is housed on adjustment hole, the screw rod of adjusting knob lower end stretches into inside, elasticity clamp upper end, in inside, elasticity clamp upper end, regulating block is arranged, the screw rod of adjusting knob lower end coordinates with the spiral shell button of regulating block upper end, the regulating block lower end connects the upper end of ejection-spring, the lower end of ejection-spring is connected to the upper end of lancet, on the lancet outer surface of upper, projection is arranged, protruding lower end on lancet is stuck on the card convex of bottom in the elasticity clamp, end opening at overcoat, the expansion piece that can slide up and down is housed, the upper surface of expansion piece is the low arc convex in middle high both sides, there is a through hole in expansion piece central authorities, through-hole diameter is greater than the full-size of lancet outer surface, it is inner that the through hole outer rim of expansion piece upper surface is placed in elasticity clamp bayonet socket bottom, expansion piece lower surface is given prominence to outside the overcoat lower port.There is the spacing block of regulating block at the middle part in the elasticity clamp.
During use, according to by blood sampling Person's skin situation, regulate adjusting knob, reach ejection-spring and be compressed to a certain degree, (compression many, when lancet launches, the larger distance of strength is just far away, can puncture thicker skin, gets blood; Lacking of compression, when lancet launches, the smaller distance of strength is just closer, can only puncture thinner skin, gets blood.）
After regulating, when blood sampling is used, the expansion piece is given prominence to the skin surface that lower surface the overcoat lower port outside is placed in the position of taking a blood sample, promote overcoat downwards, the expansion piece in overcoat on slide, the through hole outer rim of expansion piece upper surface is large with the bayonet socket support bottom of elasticity clamp, at this moment the card convex of bottom expands outwardly in the elasticity clamp, the size that expands outwardly when card convex is during greater than the size of the projection on lancet, the compressed ejection-spring bullet of lancet downwards, lancet launches the needle point prick skin, reaches the blood sampling purpose.
