Description

Infant's wrist thumb arthrodesis device

Technical field

The utility model is related to medical appurtenance, and in particular to a kind of infant's wrist thumb arthrodesis device.

Background technology

Infant is smaller because of the age, and the reaction to external irritant is more sensitive, and infant is being treated such as by hand When carrying out drip-feed at arm position, moved because its sensitive reaction easily makes its arm and palmar hand make larger repulsion Make, so as to cause the dropper bending or syringe needle displacement of drip-feed to have impact on instillation treatment, now, it is necessary to ceaselessly to dropper Had an acupuncture treatment again even being adjusted, so also easily cause the secondary injury to infant.

The content of the invention

In order to solve the above technical problems, the utility model can be to infant's arm and palmar hand, wrist there is provided one kind Infant's wrist thumb arthrodesis device so as to be influenceed when eliminating the movement response of arm to instiling is fixed in portion simultaneously.

Infant's wrist thumb arthrodesis device of the present utility model, including inner supporting structure and external coating, the interior branch Support structure includes thumb post, forearm holder and palmrest, into 145 ° of -165 ° of angles, the thumb post between the forearm holder and palmrest Into 5 ° of -8 ° of angles between palmrest, the inner supporting structure is made up of substrate and Duo Gen plastic tubes.

It is preferred that, the palmrest has the arcuate structure corresponding with the back of the hand cambered surface under nature, the forearm holder With the arcuate structure corresponding with the dorsal surface cambered surface of forearm.

It is preferred that, the forearm holder is provided with the support arm semi-ring that elastomeric material is made.

It is preferred that, the forearm holder and palmrest are structure as a whole.

It is preferred that, the outer flexi-ring structure corresponding with arm radius position is additionally provided with the forearm holder.

It is preferred that, the forearm holder is provided with forearm fixing band.

It is preferred that, the palmrest is provided with palm fixing band.

It is preferred that, the thumb post is provided with thumb fixing band.

It is preferred that, the external coating is cloth.

Infant's wrist thumb arthrodesis device of the present utility model, when in use can be by palmar hand, wrist portion and thumb Preferably fix, so that influence when eliminating the movement response of infant's arm to instiling, without being carried out not to dropper Even when adjustment have an acupuncture treatment again, eliminate risk of the infant by secondary injury.

Brief description of the drawings

Fig. 1 is the fixture structure schematic diagram of the present utility model for left arm.

Embodiment

The utility model is further detailed lower combination accompanying drawing.

As illustrated, infant's wrist thumb arthrodesis device of the present utility model, including inner supporting structure and external coating, Wherein external coating can be cotton, burlap material etc., and inner supporting structure can be wrapped in it by it by suturing or being bonded；This Inner supporting structure in device includes thumb post 1, forearm holder 3 and palmrest 2, wherein, form hand between forearm holder 3 and palmrest 2 The palm and arm are in angle α when under nature, generally 145 ° -165 ° of angles, so i.e. achievable wrist joint in Function digit；Thumb and palm are formd between thumb post 1 and palmrest 2 and is in angle β when under nature, generally 5 °- 8 ° of angles, so, you can to realize that the inner supporting structure that thumb joint is located in function digit, the present apparatus can be by substrate and Duo Gen Plastic tube is constituted, and the substrate can be softwood substrate such as cystosepiment etc., and the plastic tube is used when can be drip-feed Dropper；Palmrest in the present apparatus has the arc corresponding with the back of the hand cambered surface under nature（Face）Structure, forearm holder has The arcuate structure corresponding with the dorsal surface cambered surface of forearm, so can preferably realize wrist joint in function digit and thumb Joint is in function digit；The support arm semi-ring 4 that can be made on the forearm holder 3 provided with elastomeric material, when forearm holder 3 blocks forearm During tension, because the elastic reaction of support arm semi-ring 4 can make forearm holder not annular snap pressure forearm tissue, it is to avoid because to forearm The not enough caused necrosis of venous return that card is pressed and caused for a long time；In the present apparatus, forearm holder 3 and palmrest 2 are integrated Structure, more effectively secures the action of wrist；The outer flexi-ring structure 5 corresponding with arm radius position is additionally provided with forearm holder 3, Outer flexi-ring structure 5, which can block, to be pressed in arm radius position to limit radioulnar rotation；In addition, before forearm holder 3 is provided with Arm fixing band, palmrest 2 be provided with palm fixing band, thumb post 1 be provided with thumb fixing band, so can preferably fix forearm, The position of palm, thumb, the fixing band can be by the way of adhesion button, it would however also be possible to employ mode of buckle etc. realizes its position The fixation put.
