Description
Technical field
The utility model relates to instruments used in Chinese medicine blood-letting puncture therapy, and especially partner treatment makes in doing blood-letting puncture therapy
A kind of lancet.
Background technique
Currently, a great variety of lancet, either which kind of lancet are required when in use by disposable aspiration needle
On safety cap screw down, another one firmly or needle handle is inserted by tool (such as: the tool of small-sized nipper plier etc)
Into the hole of the pin device (generally four needles) of lancet, significant care is wanted in operation, not so can be punctured by sharp syringe needle
Skin.It after use, is similarly careful to operate when removing a syringe needle, thus be brought to user very big
Troublesome and unsafe factor.
Summary of the invention
The technology of the utility model solves the problems, such as: overcoming the deficiencies of the prior art and provide a kind of lancet, user
Just, design is simple, safe and reliable.
The technical solution of the utility model is: this lancet comprising main body, clamp ring, pin device, pen master
The front end of body is equipped with circular sleeve, and the rear end of cylindrical pin device is fixed in a main body by clamp ring, is had on pin device
There are several circular holes, the needle handle of disposable aspiration needle is inserted into circular hole, and the diameter of circular hole is greater than the diameter of the needle handle of disposable aspiration needle,
The outer wall of pin device is equipped with the wing expanded outwardly, and the quantity of wing is equal to the quantity of circular hole, after the rear end of wing is fixed on pin device
The rest part of end and wing is separated with the main body of pin device, and the front end of wing extends outward to form outer lateral edge.
Because the outer wall of pin device is equipped with the wing expanded outwardly, the rear end of wing is fixed on remaining of the rear end of pin device and wing
Part is separated with the main body of pin device, and the front end of wing extends outward to form outer lateral edge, so the long power between the front and back end of wing
Away from allowing users to easily be pinched with thumb and index finger without laborious, user need to only use thumb and food when replacing syringe needle
Refer to that the convex edge for pinching diagonal two wings on pin device can easily take off pin device from lancet, then by pin device circle
Hole lies in desktop upwards, and the needle handle for the disposable aspiration needle rear end for removing safety cap is gently put into the circular hole of pin device,
Since the diameter of the circular hole of pin device is greater than the diameter of the needle handle of disposable aspiration needle, so only needing for needle handle to be directed at circular hole pine
It opens, disposable aspiration needle will be freely fallen into the circular hole of pin device and on earth, after use, by pin device from lancet master
It is extracted on body, or pinches lateral edge outside diagonal two wings of pin device with thumb and index finger, the wing after extraction on pin device is in elastic force
Under the action of be restored to original position again, it is easy to use in this way, design is simple, moreover it is possible to avoid the skin because of careless manipulation puncturing operation person
Skin, to using just bring pain and cross-infection risk, securely and reliably.
Detailed description of the invention
Fig. 1 is the overall structure diagram of lancet according to the present utility model；
Fig. 2 is the structural schematic diagram of pin device.
Specific embodiment
Below by attached drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, this lancet comprising the front end of main body 1, clamp ring 2, pin device 3, main body is equipped with circle
The rear end of shape sleeve, cylindrical pin device is fixed in a main body by clamp ring, has several circular holes 31 on pin device,
In the needle handle insertion circular hole of disposable aspiration needle 4, it is characterised in that: the diameter of circular hole is greater than the diameter of the needle handle of disposable aspiration needle,
The outer wall of pin device is equipped with the wing 32 expanded outwardly, and the quantity of wing is equal to the quantity of circular hole, and the rear end of wing is fixed on pin device
The rest part of rear end and wing is separated with the main body of pin device, and the front end of wing extends outward to form outer lateral edge 33.
Because the outer wall of pin device is equipped with the wing expanded outwardly, the rear end of wing is fixed on remaining of the rear end of pin device and wing
Part is separated with the main body of pin device, and the front end of wing extends outward to form outer lateral edge, so the long power between the front and back end of wing
Away from allowing users to easily be pinched with thumb and index finger without laborious, user need to only use thumb and food when replacing syringe needle
Refer to that the convex edge for pinching diagonal two wings on pin device can easily take off pin device from lancet, then by pin device circle
Hole lies in desktop upwards, and the needle handle for the disposable aspiration needle rear end for removing safety cap is gently put into the circular hole of pin device,
Since the diameter of the circular hole of pin device is greater than the diameter of the needle handle of disposable aspiration needle, so only needing for needle handle to be directed at circular hole pine
It opens, disposable aspiration needle will be freely fallen into the circular hole of pin device and on earth, after use, by pin device from lancet master
It is extracted on body, or pinches lateral edge outside diagonal two wings of pin device with thumb and index finger, the wing after extraction on pin device is in elastic force
Under the action of be restored to original position again, it is easy to use in this way, design is simple, moreover it is possible to avoid the skin because of careless manipulation puncturing operation person
Skin, to using just bring pain and cross-infection risk, securely and reliably.
Preferably, the front end of the wing 32 extends inwardly to form interior lateral edge 34, the interior lateral edge the outer lateral edge backward
At 2mm, when the wing is shunk, interior lateral edge is embedded in the groove of the needle handle of disposable aspiration needle.Interior lateral edge is located at the top of wing
2mm is moved down, just parallel with the groove of the needle handle of disposable aspiration needle, wing interior lateral edge when shrinking will be embedded in a property syringe needle
In the groove of needle handle, play locked effect, will not be detached from pin device in actual use, when insertion the wing of pin device with
Deeply needle handle is lockked to contract, after use, pin device is extracted from lancet main body, or with thumb and index finger
Pinch the outer lateral edge of diagonal two wings of pin device, the wing after extraction on pin device is restored to original position again under the action of elastic force, in wing
Lateral edge automatically disengages the groove of the needle handle of disposable aspiration needle, the inversion of pin device is come, syringe needle will voluntarily fall off, and be put into recycling
Container in, not only facilitate but also not can cause environmental pollution.
Preferably, the pin device main body and the wing integrated injection molding.Making four wings of pin device, elasticity is good, intensity
It is high.
