Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a novel medical micro-damage living body blood sampling device.
Background
In medical institutions, syringes, lancets, and the like are an indispensable blood sampling device when collecting and infusing blood samples from patients. In order to aim at medical safety, the blood taking needle, the syringe and the like are all disposable, so that cross infection caused by repeated use is avoided.
Because all blood taking needles on the market at present are pure rigid metal needles, when the blood taking needle is applied to children, the technical level requirement on operators is high, 1-2 persons are often needed to assist, and meanwhile, in the process of replacing blood taking tubes, the needles often damage blood vessels due to crying, agitation and the like of the children patients, the risks of blood taking part vasospasm, subcutaneous hematoma, infection and the like are increased, the pain of the children patients and the anxiety of parents are increased, and inconvenience is caused to the development of clinical work.
In addition, if the needle does not take protective measures after blood collection or infusion, there is still a risk of injuring medical staff. At present, a method of sleeving a protective sleeve on a needle to protect the needle or prevent the needle from stabbing medical staff is widely used in medical institutions such as hospitals, meanwhile, some blood taking needles adopt the technical means of needle retraction, and the retraction structure with a spring possibly causes the needle to retract due to misoperation in the blood taking process, so that inconvenience and loss are caused to patients and medical staff.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a novel medical micro-injury living body blood sampling device, which reduces injury to sampling blood vessels, does not need high cooperation of patients and improves the working efficiency of medical staff.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a novel medical little damage living body blood sampling device, including hollow communicating pipe, the front end of communicating pipe is equipped with the blood taking needle subassembly, the side of communicating pipe be equipped with the hose of blood taking needle subassembly UNICOM, the blood taking needle subassembly includes syringe needle sleeve and locates with one heart the inside rigid metal needle core of blood taking needle subassembly, the tail end of rigid metal needle core is followed communicating pipe terminal wears out, the both sides of communicating pipe are equipped with a pair of self-adhesion pad pasting.
Further, the needle sleeve is made of flexible polyurethane.
Further, the tail end of the rigid metal needle core is provided with a handle, and when the handle is clamped on the communicating pipe, the end face of the needle head sleeve is flush with the needle head of the rigid metal needle core.
Further, the blood collection tube puncture head is sleeved with an elastic silica gel sheath.
Further, the needle sleeve is internally coated with a heparin layer.
Advantageous effects
According to the utility model, through the matching of the needle sleeve and the rigid metal needle core in the blood taking needle assembly, the needle sleeve rebounds and surpasses the metal needle core while breaking through the blood vessel wall, so that the needle is prevented from penetrating the opposite blood vessel wall, and the success rate of puncture is greatly increased.
After the needle head enters the vascular cavity, the metal needle core is pulled out from the rear of the assembly and the needle head sleeve is completely pushed in, so that only the flexible structure is reserved in the vascular cavity, and the damage to the blood vessel during long-time sampling can be reduced.
The self-adhesive films are arranged on the two sides of the communicating pipe, and can be quickly stuck on the skin of a patient and fix the blood taking device after the blood taking needle component pierces into a blood vessel, so that accidents of needle slipping caused by irritation and agitation of the patient are prevented, high cooperation of the patient is not needed, pain of the patient is reduced, and working efficiency of medical staff is improved.

Wherein, 1-communicating pipe; 2-self-adhesive film; 3-a grip; 4-a blood collection tube puncture head; 401-an elastic silicone sheath; 5-lancet assembly; 501-a needle hub; 502-a rigid metal needle; 503-a perforated sealing plug; 6-hose.
Detailed Description
The utility model will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model. Further, it is understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the present utility model, and such equivalents are intended to fall within the scope of the claims appended hereto.
As shown in fig. 1 and 2, the utility model provides a novel medical micro-injury living body blood sampling device, which comprises a hollow communicating pipe, wherein a blood sampling needle assembly is arranged at the front end of the communicating pipe, a sealing plug with holes is arranged at the tail end of the communicating pipe, a hose communicated with the blood sampling needle assembly is arranged on the side surface of the communicating pipe, the blood sampling needle assembly comprises a needle head sleeve and a rigid metal needle core concentrically arranged in the blood sampling needle assembly, the tail end of the rigid metal needle core penetrates out from the tail end of the communicating pipe, and a pair of self-adhesive films are arranged at two sides of the communicating pipe.
When the rigid metal needle core is pulled out, the center of the sealing plug with the hole automatically rebounds to form extrusion sealing, so that collected blood is prevented from flowing out of the tail end of the communicating pipe.
In one embodiment, the needle hub is made of flexible polyurethane.
In a specific embodiment, the end of the rigid metal needle core is provided with a handle, and the handle comprises an end cover clamped at the tail end of the communicating pipe and a wrench arranged at one side of the end cover. When the handle is clamped on the communicating pipe, the end face of the needle head sleeve is flush with the needle head of the rigid metal needle core.
In one embodiment, the puncture head of the blood collection tube is sleeved with an elastic silica gel sheath, so that an operator can be protected from occupational exposure, and blood backflow or ejection during replacement of the blood collection tube can be prevented.
In one embodiment, the heparin layer is coated in the needle sleeve, and the heparin layer can avoid blood coagulation blockage in the operation process to cause blood sampling failure.
When the self-adhesive pad pasting device is used, only one doctor is required to take off the pad of the self-adhesive pad pasting, the blood taking needle component is penetrated into a blood vessel of a patient, and the needle head sleeve made of elastic polyurethane can partially retract during the penetration, so that the rigid metal needle core is not influenced to puncture the skin; after the rigid metal needle core breaks through the vascular wall, the front resistance disappears, the needle sleeve can rebound to the initial length rapidly and enter the vascular cavity along a channel formed by the broken skin and subcutaneous tissue of the rigid metal needle core, at the moment, blood can enter a gap between the needle sleeve seam and the rigid metal needle core to prompt that the head end reaches the vascular cavity, and then the rigid metal needle core is pulled out in a matched mode, so that safe tube placement can be realized.
