Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

With reference to the attached drawing 1, the blood sampling and transfusion mechanism capable of relieving the pain of a patient comprises a needle point 1, a needle body 2 and a needle seat 3 which are connected in sequence, wherein a plurality of through holes 4 penetrate through the needle body 2; the free end of the needle seat 3 is sequentially connected with a blood sampling tube 5, a tee joint 6 and an infusion tube 7, and the tee joint 6 is also connected with a branch tube 8; an extension part 9 is arranged between the needle body 2 and the needle seat 3 and is used for enhancing the fixing degree with the transfusion position of a patient in the transfusion process; an anti-reflux device 10 is arranged in the blood collection tube 5 between the needle stand 3 and the tee joint 6 and is used for preventing reflux in the blood collection or transfusion process; the needle point 1 and the needle body 2 are also sleeved with a protective needle cap 11.

The utility model discloses combine blood sampling infusion to be in the same place to set up extension, prevent the device against the current, thereby alleviateed the patient misery that causes at blood sampling or infusion in-process, avoided appearing the blood against the current, reduced the risk of iatrogenic source nature infection.

The concrete during operation:

the needle head 1 is inserted into the position of a patient to be blood-sampled, and is connected with a vacuum blood vessel through a branch pipe 8 to realize the blood-sampling process; when transfusion is needed, the transfusion bottle can be directly connected through the transfusion tube 7. In the blood sampling process, because the pressure in the human body is greater than the pressure in the vacuum tube, blood finally enters the vacuum tube after passing through the backflow prevention device 10, and the blood sampling purpose is achieved. The blood collection tube 5 is provided with the backflow prevention device 10, so that backflow of blood can be prevented during blood collection or withdrawal of the needle tip 1. The through hole 4 can increase the liquid outlet area during transfusion, so the outer diameters of the needle head 1 and the needle body 2 can be reduced in specific arrangement, and the pain of a patient is further relieved.

The lower end surface of the extension part 9 is arc-shaped, and the concave surface is close to the blood sampling or transfusion position.

The lower end face of the extension part 9 is also provided with an adhesive surface with a protective film 12, the adhesive surface covers the whole lower end face of the extension part 9, and the protective film 12 and the adhesive surface are connected in a tearing way.

The protective film 12 is bonded to the bonding surface at one time, and the extension portion 9 has a flexible structure.

In the process of actual blood sampling to and at the infusion in-process, all directly insert needle point 1 and treat blood sampling or infusion position, know according to prior art, can fix needle body 2 in the infusion position through medical sticky tape at the in-process of infusion, prevent to take place the tympanic bulla, and then prevent that the infusion position from taking place red and swollen. However, according to the connection relationship and the shape among the needle tip 1, the needle body 2 and the needle seat 3 in the prior art, since the length of the needle body 2 is limited, and the infusion position of a patient, such as the upper part of the hand surface, is in a shape with a certain bulge, the stability of the needle body 2 on the hand surface is affected, and in the process of infusion, some patients often move the needle tip 1 inside the hand surface due to shaking of the infusion tube at the upper part communicated with the needle tip 1 or movement of the body of the patient, which causes red swelling of the hand surface over time.

To above-mentioned phenomenon, this application has set up extension 9 at first between needle body 2 and needle file 3, and the extension is the shape of interior concave arc of lower extreme personally submitting, including set up the bonding surface that has the tear protection film 12 on the concave surface, thereby when specifically using, needle point 1 inserts infusion or blood sampling position, owing to set up extension 9, and set up the bonding surface on the lower terminal surface of extension 9, when tearing protection film 12 down, can make interior concave arc lower extreme face and hand position paste each other and bond each other, thereby play certain fixed action, reduce because the transfer line etc. rocks the removal degree that causes needle point 1 in the hand, thereby alleviate patient's misery. In the process of not adding the extension part 9, because the needle point 1 is directly inserted into the hand surface, and the length of the needle body 2 is limited, sometimes there is a phenomenon that the straight line of the needle point 1 and the needle body 2 forms a certain included angle with the hand surface, so that the needle hole is expanded by the straight line of the needle point 1 and the needle body 2, and the bubbling phenomenon is likely to occur. The extension part 9 can increase the length of the fixing part of the device and the transfusion or blood sampling position, thereby improving the fixing firmness and reducing the pain of patients.

In order to facilitate tearing, a strip-shaped tearing strip can be fixedly connected to one end or the side part of the protective film 12, so as to facilitate tearing.

The anti-reflux device 10 includes a semicircular valve, which is an elastic structure and is provided with a Y-shaped opening.

The valve is fixedly connected inside the blood collection tube 5 and is fixedly connected with the inner wall surface of the blood collection tube 5, and the valve is close to the position of the tee joint 6.

The valve can be made of plastic materials, and the opening is enlarged in real time, so that blood can conveniently pass through the opening; however, the blood collection container tube is far smaller than the internal pressure of a human body, so that the valve is not flushed, the aim of preventing backflow is fulfilled, and the pain of a patient is relieved.

Two of them open ends of tee bend 6 are all established with heparin tube 5, transfer line 7 and are connected by the cover, and heparin tube 5 and transfer line 7 all establish the inside at tee bend 6 interface in the cover.

The protective needle cap 11 is a hollow cylindrical structure with one end open.

The protective needle cap 11 plays a certain role in protecting the needle head 1 and the needle body 2 from being polluted.
