Description

A kind of elbow joint restraint device

Technical field

The utility model relates to a kind of medical instrument, in particular to a kind of elbow joint restraint device.

Background technique

In clinical position, the various pipelines of indwelling are needed such as: stomach tube, urinary catheter, deep vein catheter and postoperative various drainage tubes Road, but because the patient mood having compares fluctuation and impatience, therefore need that the arm of patient is limited in disease using the way of restraint On bed.Currently used mode is patients wrist or forearm to be fixed on bed body side using binding mode, deposited with a soft band Shortcoming: 1) dynamics control it is bad, tether is excessively loose, and patient's both hands are easy to loosen or skid off；2) most of band body is all Simple flexible material, in use process, patient is restless, and band, which is known from experience, is crimped to hawser shape, is easy to cause the feelings such as ankle injury to patient Condition；3) for current constrained substantially in wrist joint, the restless constraint tension of patient, which is easy to cause, beats the positions such as remaining needle redness, First is that cost of idleness second is that hurt distal vessels, is unfavorable for living patient's vein fluid-supplement therapy long.4) family members are to patient's unexpectedly drawn tubes Attention degree is not high, can not bear to bundle security constraint, excessively trusts patient's self-control, causes unplanned property decannulation rate high.

Utility model content

In view of the deficienciess of the prior art, the technical problem to be solved by the present invention is to provide a kind of constraints of elbow joint Device, can not only effectively prevent patient's arm to be significantly bent leads to unexpectedly drawn tubes, moreover it is possible to greatly increase the comfortable of patient Degree.

To achieve the goals above, the utility model is achieved through the following technical solutions: a kind of elbow joint constrains Device, including support frame, joint frame and adjustable shelf, support frame as described above are half cylindrical tube, and support frame as described above axial ends is symmetrical It is disposed with shaft, the joint frame and the adjustable shelf and is connected respectively with support frame as described above switching by shaft, the joint frame It is arranged symmetrically with the adjustable shelf, the joint frame side wall setting is fluted, and bolt, the groove are provided on the adjustable shelf Connection, the closing piece for being provided with a lockhole right above the groove and being adapted to lockhole, the lockhole are adapted to the bolt grafting It is connected through a screw thread with the closing piece.When needing fixed elbow joint after patient cannula, arm is put into this elbow joint and is about got one's things ready It in setting, is located just at ancon right above ancon, then difference cradle head frame and adjustable shelf, the bolt on adjustable shelf is inserted into In groove on the frame side wall of joint, further according to the size of patient's arm diameter, the depth of insertion is adjusted, after the completion of the adjustment of position, Closing piece is simultaneously firmly withstood bolt by rotation closing piece, and whole device fixation just finishes.The present apparatus can not only effectively prevent patient The comfort level that arm, which is significantly bent, to be led to unexpectedly drawn tubes, greatly increase patient, moreover it is possible to which ruler is adjusted according to patient's arm size It is very little, adapt to the demand of different patients.

Further, joint frame both ends are symmetrically arranged with an elastic webbing, and described elastic webbing one end is fixed on joint On frame, the other end is connected to adjustable shelf end by active connection, and the active connection is thread gluing.This elasticity strip length can With flexible, when such elbow joint bending, arm can bending appropriate to a certain degree, but hand cannot get at stomach tube, urinary catheter etc. The position of intubation, increase scope of activities appropriate in this way, further increases patient comfort.

Further, middle part is fixed with an ancon in support frame as described above, ancon length and shape when exposed to external forces It can become.When elbow joint bending, the ancon is outwardly protruded, and can be bonded elbow joint very well, elbow joint is stuck in evagination at this time Ancon at, arm squeezes on two elastic webbing of the present apparatus, forms three-point fix, and such elbow joint is by even at the cost of one's life at ancon, arm It is closer with present apparatus fitting, so that phenomena such as present apparatus frame falls off in use process will not be caused.

Further, be fixed with a support cushion inside support frame as described above, the support cushion size and shape with it is described Support frame is adapted to, and has a through-hole in the support cushion, the hole size is adapted to position with the ancon.Support cushion and Through-hole allows patient's arm to be close to the present apparatus, and can increase conformal performance and comfort.

Further, the joint frame inner wall is all fixed with medical cushion, and the medical cushion is adapted to the joint frame, The adjustable shelf inner wall is also fixed with medical cushion, and the medical cushion is adapted to the adjustable shelf.Medical cushion have it is ventilative, Conformal effect, to increase patient comfort.

Further, support frame as described above lateral wall has been arranged symmetrically fixing belt.When needed, fixing belt can be passed through By the present apparatus and patient's arm fixation in the fixed position such as bedstead, prevent patient from tampering.

The utility model has the beneficial effects that

When needing fixed elbow joint after patient cannula, arm is put into this elbow joint restraint device, makes ancon just Right above ancon, then difference cradle head frame and adjustable shelf, the bolt on adjustable shelf is inserted on joint frame side wall In groove, further according to the size of patient's arm diameter, the depth of insertion is adjusted, after the adjustment of position, rotates closing piece and by closing piece Bolt is firmly withstood, whole device fixation finishes.The present apparatus, which can not only effectively prevent patient's arm to be significantly bent, to be caused Unexpectedly drawn tubes greatly increase the comfort level of patient, moreover it is possible to adjust size according to patient's arm size, adapt to the need of different patients It asks.
