Abstract
The invention discloses a puncture device causing less pain. The puncture device comprises a blood taking needle, a rod head, a rod body and a tail rod, wherein the rod head is fixed to the front end of the rod body; the tail rod is arranged at the back end of the rod body; an ejection assembly is arranged in the rod body; a needle seat is movably connected in the rod head; a handle rod of the blood taking needle is connected in the needle seat; the front end of an ejection rod in the ejection assembly is over against a carrier rod communicated with the back end of the needle seat. In the puncture device causing less pain having the structure, the ejection device is separated from the needle seat of the blood taking needle, thereby interrupting deviation shake caused by ejection of the ejection device in the transmission process of the needle seat, preventing the phenomenon of shake or deviation of the blood taking needle in a skin contact process, and reducing pain of a patient. Moreover, by improving an indicating sleeve and the tail rod, the infection risk of an operator is further lowered, the operation efficiency is increased, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to medical diagnosis technique with the apparatus field, be specifically related to a kind of Centesis instrument of the micro blood sample collection that can alleviate particular patient pain.
Background technology
Quantitative assay for Related Component in human body fluid in modern medicine is very general, for example, for specific patient, need to glucose in blood, lactate, cholesterol and bilirubin etc. be monitored, be analyzed.Early stage operator uses independently the blood taking needle patient skin that manually punctures to form a wound and gather blood sample, and the method has higher technical requirement and certain mental pressure for operator and particular patient, and patient keenly feels greatly.
On March 12nd, 1985, United States Patent (USP) disclosed a kind of sting device No. 4503856, this device has a tube-like envelope, one is arranged in slidably blood-taking needle holder of shell, to provide, clamper is pushed forward to the strength in the perforation position of skin with a compressible spring, clamper is got back on its neutral gear position subsequently.Its operation principle is that side kayser launches.This patent has been started has certain representational technical scheme, and operator is not directly gripping the realization puncture sampling of less misery under blood taking needle state.
Thereafter insider and enterprise constantly improve for the device of skin penetrating sample of blood, drawn.On July 9th, 1985, United States Patent (USP) disclosed a kind of sting device No. 4527561, this device includes second spring to regain blood-taking needle holder (also can referring to United States Patent (USP) the 4535769th and No. 4553541) after lancet penetrates user skin, further perfect sting device.
Other are representative improves as nineteen ninety December United States Patent (USP) on the 11st discloses a kind of blood lancet device No. 4976724, and this device comprises that a kind of mechanism can allow user penetrate the blood taking needle using and get along well that its contacts.And for example on June 7th, 1994, United States Patent (USP) disclosed a kind of blood lancet device No. 5318584, increased paracentesis depth control and adjusted function, this device comprise a kind of rotation, slip transmission system can in the case of adjustable, repeatably penetration depth and less misery, carry out puncture.
Although sting device and the multiple same device take blood collecting pen as title are constantly improving or upgrading distortion, mainly relate to the selecting of component materials, configuration design, its basic functional principle is that side kayser ejection mechanism does not have basic change.This structure has a feature, and there is the lancet holder of a prolongation at device center.While entering percussion SBR, lancet holder ad hoc structure coordinates with the structure kayser of being located at device sidewall, when operating, operator presses the trigger unit of projecting device appearance, kayser status releasing, and lancet holder automatically resets after having launched forward puncture operation.To be lancet holder ad hoc structure remove while contacting with the latching structure of being located at device sidewall its deficiency, cause lancet holder distortion or lateral deviation, and then inevitably make to be assembled in the synchronous lateral deviation of blood taking needle of lancet holder front end, when blood taking needle moves forward in free state, the inevitable opposite direction to distortion resets, so cause blood taking needle can not move linearly vertically in the time that target site is launched, the fact is a kind of movement in a curve track, the inevitable needle point shake of skin puncture moment causes larger stimulation and wound to subcutaneous teleneuron to expand, increase patient's pain and the probability of infection.
In addition, there is the loaded down with trivial details problem that uses in existing sting device.For preventing different patient's cross infections, blood taking needle matching used with it is disposable use, the blood taking needle that therefore every subjob need to more renew.Complete after the collection of one-time puncture blood sample, blood taking needle must be removed from sting device, its method has two kinds: the one, and direct hand-driven moving removes, operator's fingerhold completes the blood taking needle of puncture operation it is forced to extract from keeper, this operation measure is loaded down with trivial details, and operator easily touches needle point and the blood of blood taking needle front end, there are mental pressure and larger infection risk; The 2nd, utilize the pressure ejecting device of being located on sting device to remove, this pressure ejecting device is generally the push rod or the collar that are attached to sting device outside, and be connected as a single entity and extend to the member of blood taking needle keeper bottom with push rod or the collar, it is modular construction complexity not only, assembling is complicated, easily damage, affect product attractive in appearance, and removing more loaded down with trivial detailsly, its order is: remove Cang Gai (rotation or drawing), and---operation push rod or the collar travel forward and force to release the manually retracted push rod of blood taking needle-----or the collar.In use procedure, operator needs repeatedly spiral installation or removal blood samplings needle chamber lid, and to complete withdraw of the needle operation, complex operation, service efficiency are poor.
Sting device in use has the action of rotation indicating sleeve and post-tensioning foot piece, need to increase the frictional force of parts and operator's hand, existing structure is on functional unit, to establish recess or bulge loop, but the mould complexity of this structure, has increased the production cost of product.
