Abstract
The utility model discloses a fixing structure of a blood sampling needle head, which comprises a first clamping plate and a second clamping plate; the first clamping plate and the second clamping plate are rigid plates with semi-elliptical ring structures in vertical sections, one ends of the first clamping plate and the second clamping plate are connected through hinges, the other ends of the first clamping plate and the second clamping plate are provided with a plurality of groups of ring belts corresponding to the positions, and each group of ring belts are connected by winding elastic belts; the inner wall of first splint and second splint is equipped with the cushion, plays comfortable effect with patient's skin contact, and the cushion middle part on the middle part of first splint and the first splint inner wall all is equipped with the through-hole, makes the elbow median vein of elbow medial surface expose, makes things convenient for the syringe needle to insert.
Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to fixed knot of blood sampling syringe needle constructs.
Background
In the process of blood sampling or blood transfusion for children, the position of the needle head can be moved due to the good movement of the children, the needle head needs to be fixed by the adhesive tape again, the vein of the elbow median vein is thick and straight, and the blood sampling or blood transfusion device is particularly suitable for blood sampling and blood transfusion, but the process needs several minutes to dozens of minutes, and the needle head is easy to dislocate once the elbow is bent, so that the blood sampling or blood transfusion process is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical problem, the utility model provides a fixed knot of blood sampling syringe needle constructs can fix the elbow joint, prevents that the syringe needle from misplacing easily.
The utility model provides a technical scheme that its technical problem adopted is: a fixing structure of a blood sampling needle head comprises a first clamping plate and a second clamping plate; the first clamping plate and the second clamping plate are rigid plates with semi-elliptical ring structures in vertical sections, one ends of the first clamping plate and the second clamping plate are connected through hinges, the other ends of the first clamping plate and the second clamping plate are provided with a plurality of groups of ring belts corresponding to the positions, and each group of ring belts are connected by winding elastic belts; the inner wall of first splint and second splint is equipped with the cushion, plays comfortable effect with patient's skin contact, and the cushion middle part on the middle part of first splint and the first splint inner wall all is equipped with the through-hole, makes the elbow median vein of elbow medial surface expose, makes things convenient for the syringe needle to insert.
The surface of first splint and second splint is equipped with a plurality of evenly distributed's bleeder vent, can increase the gas permeability of elbow skin.
The soft cushion is preferably a foamed silica gel cushion, and is safe, environment-friendly and high in air permeability; the inner wall of the soft cushion is provided with a plurality of anti-skid particles or anti-skid stripes which are uniformly distributed, so that the friction force between the soft cushion and the skin is increased.
The elastic belt is made of rubber or latex, is high in elasticity and not prone to breaking, and is convenient to wash and clean.
The utility model has the advantages that the fixing structure of the blood sampling needle head fixes the elbow joint through the two clamping plates, so that the elbow joint can not be bent easily; the needle head punctures the median elbow vein through the through hole on the first splint.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a plan view of the present invention.
Fig. 2 is a cross-sectional view a-a of fig. 1.
The figure shows 1, a first splint, 2, a second splint, 3, a hinge, 4, a ring, 5, an elastic band, 6, a soft pad, 7, a through hole, 8, a vent hole and 9, anti-skid particles.
Detailed Description
Referring to fig. 1-2, a fixing structure of a lancet head includes a first clamping plate 1 and a second clamping plate 2; the first splint 1 and the second splint 2 are hard plates with semi-elliptical ring structures in vertical sections, and the materials are preferably common medical splints, such as polyurethane splints and resin splints; one ends of the first splint 1 and the second splint 2 are connected through a hinge 3, and the two splints can rotate through the hinge, so that the splint is suitable for patients with different statures; the other ends of the first clamping plate 1 and the second clamping plate 2 are provided with a plurality of groups of belt rings 4 corresponding to each other in position, each group of belt rings 4 are connected by winding elastic belts 5, so that the included angle between the two clamping plates is fixed, the elastic belts 4 are preferably made of rubber or latex materials, and are strong in elasticity, difficult to break and convenient to wash and clean; in order to increase comfort, a layer of cushion 6 is adhered and fixed on the inner walls of the first clamping plate 1 and the second clamping plate 2, and the cushion 6 is preferably made of foamed silica gel, so that the novel medical splint has the advantages of safety, environmental protection and strong air permeability; in order to prevent the soft cushion 6 from sliding at the elbow, the inner wall of the soft cushion 6 is provided with a plurality of anti-slip particles 9 which are uniformly distributed, so that the friction force between the soft cushion 6 and the skin is increased, the middle part of the first clamping plate 1 and the middle part of the soft cushion 6 on the inner wall of the first clamping plate 1 are both provided with through holes 7 for the needle to pass through, and after the elbow is clamped by the two clamping plates, the median elbow vein at the inner side surface of the elbow is exposed, so that the; in order to increase the air permeability of the elbow skin, a plurality of air holes 8 can be uniformly distributed on the surfaces of the first splint 1 and the second splint 2.
When the utility model is used, a patient straightens the arm, the first clamping plate 1 covers the inner side surface of the elbow, the second clamping plate 2 covers the outer side surface of the elbow, the elbow median vein is exposed at the through hole 7, and the elastic belt 5 is tightened to tightly clamp the two clamping plates at the elbow, so that the elbow can not be loosened easily; the product can be sterilized by conventional disinfectant and ultraviolet lamp.
