Description
Technical Field
The invention relates to the technical field of blood taking needle holders, in particular to a blood taking needle holder.
Background
The blood taking needle is an instrument for collecting blood samples in the medical examination process and comprises a needle head and a needle rod, wherein the needle head is arranged at the head part of the needle rod, a protective sleeve is connected on the needle rod in a sliding way, a return spring is arranged between the protective sleeve and the needle rod, and the initial position of the protective sleeve is positioned at the head parts of the needle head and the needle rod.
First generation: willow leaf needle
The needle is made of a whole metal sheet, the needle is 3-4 cm long and is like a willow leaf, the head of the needle is provided with a needle point with a fixed length, the length of the needle point is about 2-3 mm, the bottom of the needle point is expanded and used for controlling the depth of the needle, and a groove is formed in the middle of the needle point and penetrates from the needle point to the needle tail. The package is simple and easy, and is easy to be polluted.
And (4) second generation: plastic compression molding needle
The plastic needle is molded by plastic compression, the needle point is made of metal such as stainless steel, each needle is provided with a plastic needle cap, and the package is more independent. The needle cap is taken off before use, so that pollution is prevented, the needle head is small, the pain of a patient is reduced by proper operation, and the psychological pressure of the patient can be relieved; low cost and disposable use.
The common defects of the first generation and the second generation are as follows: the pain is strong, the size of the wound mainly depends on the experience and professional quality of clinical laboratory workers, the wound of a patient is too close to the fingers or gloves of the workers, and the possibility of blood cross contamination among patients still exists.
And a third generation: mechanical blood taking needle
The mechanical device is adopted, the needle head adopts the ejection device, the accurate, rapid, moderate depth and straight path piercing of the skin can be almost completely realized, and the pain of the patient is greatly reduced. The problems of strong pain, large wound and the like of the blood taking needles in the first two generations are basically solved. The appearance of the blood taking needle of the generation is of a pistol type, a pen type and the like.
Fourth generation: laser blood taking needle
The strong energy of the laser is utilized to instantaneously burn the tissue and penetrate the skin to form a bleeding point. The blood sampling instrument has very small wound, and the depth can be adjusted according to the skin condition of a patient by adjusting the laser intensity. In addition, the blood sampling instrument has no actual physical contact with a patient, and even if tiny blood spots are sprayed out, the cross contamination of blood can be completely avoided by replacing the laser emitting head, so that the blood sampling instrument is safer.
Split type
The split type blood taking needle is a disposable blood taking needle which is generally used clinically, basically replaces a blood taking mode of an injector used in the last century, and is often matched with a disposable blood taking tube for use.
The structure is that a blood collecting needle is connected with a needle seat at the tail end of a hose of an intravenous infusion needle. When the vacuum blood collection needle is used, the blood collection needle needs to be rotationally fixed at the front end of the outer cylinder of the needle holder, the vein puncture is carried out by holding the vein puncture needle by hand, after the vein puncture is successfully carried out, the vacuum blood collection tube is inserted into the cavity at the rear end of the needle holder, the blade opening of the blood collection needle penetrates through the blood blocking sleeve and penetrates into the rubber plug of the vacuum tube, and blood is sucked into the blood collection tube under the action of negative pressure. When needed, the blood can be collected by multiple tubes by repeating the steps; after blood sampling is finished, the vein puncture needle is pulled out, local hemostasis is carried out, the blood sampling needle is taken down from the needle holder, and the blood sampling needle and the vein puncture needle are discarded in a waste box.
The method is characterized in that: after the blood taking needle is launched, the needle core is locked, so that the blood taking needle can be used only once, and the safety of a user can be ensured; the design of pressing type emission provides the simplest operation for a user; the high-quality and ultra-sharp triangular needle head is designed, so that the skin can be quickly punctured, and the pain of a patient is reduced; the needle head models and the puncture depths of various specifications are suitable for the requirement of most blood volume collection.
Pen type blood taking needle
Pen lancets are not used in many clinical settings. The structure is a through needle tube, both ends of the needle tube are provided with sharp cutting edges, the middle-lower section of the needle tube is fixed on a needle base, the front end of the needle tube is called a vein puncture needle, the rear end of the needle tube is called a blood collection needle, the surface of the blood collection needle is provided with a blood blocking sleeve, and both ends of the needle tube are provided with protective sleeves. In clinical practice, blood is usually collected by using a needle holder and a disposable blood collection tube together.
When the blood collection needle is used, the blood collection needle is rotationally fixed at the front end of the outer cylinder of the needle holder to carry out venipuncture, after the venipuncture is successful, the vacuum blood collection tube is inserted into the cavity at the rear end of the needle holder, the blade opening at the rear end of the blood collection needle penetrates through the blood blocking sleeve and penetrates into the rubber plug of the vacuum tube, and blood is pumped into the blood collection tube under the action of negative pressure. The collection of multitubular secondary blood samples can be realized by repeating the steps.
Artery blood taking needle
The artery blood sampling has important significance for judging and treating hypoxemia. The artery blood sampling is the basis for accurately judging hypoxemia.
The method is characterized in that: the needle head is strictly fixed by the arterial blood gas needle cylinder, the danger caused by the looseness of the needle head in the whole process of collecting arterial blood samples is prevented, and the molecular density of the wall of the blood taking needle cylinder and the double-closed needle plug effectively prevent the blood gas samples from gas exchange with the outside. The blood sampling quantity can be preset according to the test requirement before blood sampling, so that the artery puncture operation is safe and simple, and the waste of blood samples is avoided. The design of the hole stone at the rear end of the needle cylinder forms a unique automatic exhaust device, residual gas in the needle cylinder can be rapidly and safely automatically exhausted under the action of arterial pressure, and interference of dead space gas on an arterial blood gas detection result is avoided.
In recent years, vacuum tube one-step direct blood sampling has become a more advanced blood sampling means. The vacuum tube adopts a blood sampling device with three kits, namely a double-head blood sampling needle, a needle holder and a vacuum blood sampling tube, for one-step direct blood sampling. The existing needle holder mainly comprises a blood taking needle connecting seat and a blood taking tube outer sleeve, the blood taking needle connecting seat is positioned at the front end of the outer sleeve, a double-head blood taking needle is fixedly installed, one end of the double-head blood taking needle is positioned at the front end of the needle holder and used for puncture, and the other end of the double-head blood taking needle is positioned in the outer sleeve of the needle holder and used for connecting and matching with a vacuum blood taking tube for blood taking. After blood sampling is finished, the needle holder and the double-head blood taking needle can be separated only by operating two hands simultaneously, the blood taking needle is disposed, the operation is troublesome and complicated, and the exposed needle head has great unsafe factors.
