Wrist protective sleeve

Technical field

Device when the present invention relates to a kind of puncture, wrist protected.

Background technology

Venous detaining needle, radial artery puncturing etc. often need to protect wrist; such as venous detaining needle; be applicable to child; but child is not enough to the understanding of things; do not understand and how to protect oneself; wrist, palm moving phase to arbitrarily not evading remaining needle in endovascular extension, easily produces injury to oneself.

For another example radial artery puncturing, so-called radial artery, it is first through between brachioradialis and pronator ters in human body, then descending between brachioradialis tendon and flexor carpi radialis muscle tendon, around processus styloideus radii to the back of the hand, wear the 1st intermetacarpal spaces to palm, coincideing with metacarpal artery,volar,deep forms deep palmar arch.Radial artery hypomere is only hidden by skin and fascia, is the position of clinical touch pulse.Arterial blood gas analysis can objectively respond the nature and extent of respiratory failure, is to judge the reliable method of patient with or without anoxia and carbon dioxide retention.To instructing oxygen therapy, regulating the various parameter of mechanical ventilation and correction soda acid and electrolyte imbalance all to have very important significance.Often select radial artery puncturing to gather ABS clinically and do blood gaseous analysis.

Because radial artery is relatively thin, venipuncture difficulty is larger, require that patient's arm keeps flat naturally, because operator's left index finger need touch radial artery pulse, cannot tighten the skin of site of puncture, make site of puncture cutis laxa, during inserting needle, patient obviously feels site of puncture pain, some patients, because tolerating, even refuse puncture; Because of can not fixed radial tremulous pulse well, during puncture, radial artery easily slides, and causes repeated localised puncture or easy puncture failure.Therefore, be auxiliary radial artery puncturing, need to be fixed wrist.

Hospitals at Present generally adopts such as frame palm to carry out the fixing of wrist or palm, and so-called its main body of frame palm is in fact one piece of hard plate, the hard plate of such as bank card and so on can be used to replace when frame palm is not enough.During use, frame palm or similar hard plate are placed in palm or wrist correct position, then carry out the fixing of frame palm with adhesive tape.

Frame palm shape system is relatively simple, can not effectively and human physiological structure match, also often do not match with corresponding operation.

Chinese patent literature CN202446578U discloses a kind of venous detaining needle anti-drop device, and it is furnished with glove, can be enclosed within patient on hand, then carries out it reliably fix at auxiliary such as wrist strap, cuff.Its main body shortcoming rigidity, is mainly used in essence prevent coming off of remaining needle, and can not avoids the upset of wrist, palm.

Detailed description of the invention

With reference to a kind of wrist protective sleeve shown in Figure of description 1; it is its deployed configuration; should be noted that in addition; said " cover " comprises but do not represent is all the cover covering circumference; otherwise illustrated such as relatively long band 7 just loses meaning; the adjustment of " cover " size is realized, with the use of satisfied different diameter of axle arm by band 7.

" cover " main body in figure, be found in the matrix 3 in figure surround the scope of arm, should contain arm front and two sides, the arm back side can partly be contained, and is conducive to such as the adjustment of " band 7 " length, to adapt to different patients.

Nature, between adult and child, arm size differences is very large, and this programme does not relate to the adaptability of full age bracket, can be made into the model of each segmentations such as such as child, teenager, youth, therefore, need not emphasize its adaptability the most widely.

In the referential on basis, coupling palm of the hand the back of the hand, palm of the hand side represents front, and dorsal side indicates the back side.

In the referential on basis, be configured to inwardly between the both sides that in Fig. 1, banding holes 12 and band 7 limit, otherwise, then be outside, if inner side, by restriction limit such as figure in the right side of matrix 3 left margin.

See the structure shown in Fig. 1-3, the wrist protective sleeve limited is provided with a matrix 3, and the main body of this matrix 3 is the rectangular sheet that soft material makes.

The soft material preferred plant fiber used, such as cotton, numb, cost is low, good permeability.

The soft material used slightly also is chosen as other hydrophilic materials, mainly hydrophilic fibre, and such as aforesaid linen-cotton belongs to hydrophilic fiber material.

About described hydrophilic fibre (hydrophilicfiber), refer to the fiber that regain is greater than 4.5%, hygroscopicity is stronger, such as cotton or numb.The macromolecular chain of this fibrid has the group (as-OH ,-NH, C=O etc.) of the stronger polarity of some, hydrogen bonded can be formed with hydrone.The marginal portion of its amorphous region and crystal region is comparatively large, and molecular structure is comparatively loose, and hydrone easily gos deep in the slight void of fiber surface.

Hydrophilic fibre is of a great variety, and therefore, the hydrophilic fibre selection range being adapted to this programme is also very wide.And known all natural fibers, as silkworm silk, the rabbit hair, camel hair, cotton, fiber crops etc., all belong to hydrophilic fibre.Regenerated fiber in staple fibre is as identical with cotton fiber in its chemical composition of viscose rayon, so also belong to hydrophilic fibre.And all synthetic fibers are as terylene, chinlon, spandex, polypropylene, polyvinyl chloride fibre etc., all belong to non-hydrophilic fiber, be also called hydrophobic fibre.

One of typical feature of hydrophilic fibre is that its fabric can absorb water and can timely by discharge that inhaled water is very fast, this is also that to wear the clothes comfortableness of hydrophilic fibre why better, reason is also the textile manufactured by hydrophilic fibre, the steam that human body is discharged can be distributed in time, make user feel comfortable, there is no stuffy, air-locked bad impression.

Matrix 3 preferred plant fiber, such as cotton or burlap make, in order to gain in strength, can containing netted structure sheaf, by do not affect ventilative premised on.

In certain embodiments, can also adopt with matrix 3 structure of cotton or the fiber crops multiple structure that is substrate, other parts of structure sheaf can make hole, to improve breathability.

Point out in aforesaid content, do not form circumference completely in " cover " most application and surround structure, and have the part of exposure, the part of such as mating the back of the hand comes out, and does not affect fixing, but has good breathability.

It should be noted that so-called rectangular sheet is not the rectangle on geometric meaning, and represent the rectangle of macroscopic view, such as hexagon-headed bolt, does not represent that it is proper hexagonal prism.Such as, in figure, four drift angle corners process of rectangle.

In structure in FIG, the opposite side that main body is relative, such as, the right and left shown in figure is configured to fillet, connects to make main body form cover in order to coupling.

About the connection of two fillets, can be autologous connection, such as, adopt the connected mode of snap-fastener, matrix 3 part contains elastomer, also can meet the needs that adjusting sleeve is enclosed.

Fillet can also add other syndetons, and fillet is as connection matrix, and additional syndeton connects for realizing.Band 7 such as shown in Fig. 1 and the structure of banding holes 12.

Also containing a location structure in figure, namely inside one end of a fillet, preset distance place has what represent up and down in a thumbhole 11, figure is exactly the bearing of trend of fillet, and said one end refers to the end on this bearing of trend.Inner side is then expressed as " interior " between two fillets, and on usually understanding, " inner side " does not exceed 1/3rd places of two back gauges from this fillet herein, with under the structural condition of matching construction " cover ", and coupling forearm front and both sides.

Like this, when thumbhole 11 be worn to finger upper time, one can be formed and also can produce the constraint of circumference simultaneously in " cover " axial constraint, and limit the position of other parts, such as, mention gripper shoe etc. below.
