Description

Fixing device for arteriovenous puncture

Technical Field

The utility model belongs to the technical field of medical instrument, specifically speaking especially relates to a fixing device is used in arteriovenous puncture.

Background

Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract necessary substances for assay, gas or contrast agent is injected into the body cavity to perform contrast examination, or medicines are injected into the body cavity. The purpose of puncture is to draw blood for examination, blood transfusion, fluid infusion and to put in a catheter for angiography. Along with the unconscious removal of patient in the puncture process, lead to puncture skew or hemorrhage easily, adopt simple and easy device to fix patient's hand among the prior art mostly, not only fixed effect is poor, along with the removal of patient's arm, the problem of puncture skew appears once more moreover, and then can produce mechanical oppression nature damage to patient's hand when adopting special fixing device to fix.

Disclosure of Invention

The utility model aims at providing a fixing device for arteriovenous puncture which has good fixation, convenient observation and small mechanical compression aiming at the defects existing in the prior art.

In order to realize the technical purpose, the utility model discloses the technical scheme that fixing device adopted for arteriovenous puncture is:

the utility model provides a fixing device is used in arteriovenous puncture, is including wearing in the body of human palm and elbow portion, this internal gasbag layer that prevents to produce mechanical extrusion that is equipped with, the body includes palm portion and the arm of integrative connection, the arm extends to elbow department by the wrist, palm portion surface is equipped with the transparent window who is convenient for observe the puncture condition, the transparent window outside is close to wrist department and is equipped with the through-hole, be linked together through the constant head tank between transparent window and the through-hole, transparent window includes inside casing and frame, inside casing and frame both ends involution, it is equipped with transparent plastic to inlay between the inside casing, the cavity that forms between inside casing and the frame comprises plastic layer, spontaneous heating material layer, non-woven fabrics layer and plastic layer from top to bottom, and lower part plastic layer covers and locates palm portion surface, the transparent window both sides are equipped with the magic subsides respectively.

Preferably, the diameter of the through hole is larger than the inner diameter of the positioning groove.

Preferably, the transparent window is arranged at the site of the artery and vein on the back of the hand or the artery and vein on the surface of the wrist.

Preferably, the cross section of the transparent window is quadrilateral, circular or oval.

Preferably, a plurality of fixing belts are wound on the surface of the arm part.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses set up the body into palm portion and arm, and set up the gasbag layer inside it, make the patient keep palm portion and elbow portion activity unanimous, realize that the hand is effectively fixed, avoid patient's puncture in-process to remove at will, lead to the problem of puncture failure, avoid the body to produce mechanical compression to human hand again simultaneously, utilize transparent window to make medical personnel observe the puncture condition in real time, promote the validity of treatment, alleviate the cold sense that brings after the puncture through spontaneous heating material.

Drawings

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

fig. 2 is a schematic structural diagram of the transparent window of the present invention.

In the figure: 1. an air bag layer; 2. a palm portion; 3. an arm portion; 4. a transparent window; 5. a through hole; 6. positioning a groove; 7. an inner frame; 8. an outer frame; 9. a plastic layer; 10. a self-heating layer; 11. a non-woven fabric layer; 12. magic tape; 13. and (7) fixing the belt.

Detailed Description

The invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1-fig. 2, a fixing device is used in arteriovenous puncture, including dressing in the body of human palm and elbow portion, this internal gasbag layer 1 that prevents to produce mechanical extrusion that is equipped with, the body includes integrative connection's palm portion 2 and arm 3, the arm extends to elbow department by the wrist, 2 surfaces in palm portion are equipped with the transparent window 4 of being convenient for observe the puncture condition, the transparent window 4 outside is close to wrist department and is equipped with through-hole 5, be linked together through constant head tank 6 between transparent window 4 and the through-hole 5, transparent window 4 includes inside casing 7 and frame 8, inside casing 7 and the involution of frame 8 both ends, it is equipped with transparent plastic to inlay between inside casing 7, the cavity that forms between inside casing 7 and the frame 8 from top to bottom comprises plastic layer 9, spontaneous heating material layer 10, non-woven fabrics layer 11 and plastic layer 9, and lower part plastic layer 9 covers and locates the 2 surfaces in palm portion, spontaneous heating material layer is made by iron powder, stone, active carbon, inorganic salt and water mixture, transparent window 4 both sides are equipped with magic subsides 12 respectively. Wherein, the air bag layer 1 is arranged in the body, so that the device is prevented from generating mechanical compression damage to hands; the transparent window 4 is arranged on the back of the hand or the wrist, so that medical staff can observe the puncture condition conveniently at any time.

The diameter of the through hole 5 is larger than the inner diameter of the positioning groove 6. The puncture process is limited by limiting the inner diameters of the through hole 5 and the positioning groove 6.

The transparent window 4 is arranged at the position of an artery and vein on the back of a hand or the position of an artery and vein on the surface of a wrist, and the section of the transparent window 4 is quadrilateral, circular or elliptical.

The surface of the arm part 3 is wound with a plurality of fixing belts 13. The arm 3 is firmly connected with the arm of the human body through a plurality of fixing belts 13.

The utility model discloses during the use, the body sets up to palm 2 and arm 3, make palm and arm keep the activity unanimous, and then reach fixed effect, the pjncture needle inserts the artery and vein that is in under the transparent window 4 along constant head tank 6 through-hole 5, constant head tank 6 has realized effective guiding nature, the puncture in-process, between air admission non-woven fabrics layer 11 and the lower part plastic layer 9, the oxygen content increases, the internal pressure increases, see through the non-woven fabrics layer 11 afterwards and send out the heat with the 10 materials contact of spontaneous heating layer, alleviate the cool sense of ice that the puncture brought.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications in the shape, structure, characteristics and spirit of the claims of the present invention should be included in the scope of the claims of the present invention.
