The present invention will be further explained by the following examples and drawings.

Example 1

As shown in fig. 1, a portable transfusion fixer, including infrabasal plate 1 and the upper substrate 2 that covers mutually, the two right side is connected through pivot 4, and the position when the fixed lid of buckle is closed is passed through in the left side, just infrabasal plate 1 internal surface is provided with the recess that link up and set gradually around, includes:

a first groove 10 for accommodating a catheter connected with a heparin cap of an indwelling needle, a second groove 11 for accommodating the heparin cap, a third groove 12 for accommodating a needle holder of a syringe connected with the heparin cap at the time of intravenous injection, and a fourth groove 13 for accommodating a catheter connected with the needle holder of the syringe;

the diameter of the first groove 10 is smaller than that of a heparin cap of the indwelling needle, and the diameter of the fourth groove 13 is smaller than the width of a needle head handheld part of the syringe;

the groove of the upper substrate 2 corresponds to the groove of the lower substrate 1 in position, and the covered cavity is matched with the sizes of the parts accommodated in the cavity, so that the positions of the parts accommodated in the cavity are prevented from moving relatively;

wherein, the groove sizes of the upper substrate 2 and the lower substrate 1 can be the same and corresponding. At present, the heparin cap is cylindrical, so the cross section of the second groove 11 is semicircular, and the first groove 10 has two functions, one is used for placing a catheter connected with the heparin cap, and the other is used for placing the heparin cap to slide off from the second groove 11, therefore, the cross section diameter of the first groove is smaller than that of the second groove 11, and the cross section is also semicircular.

The hand-held portion of the syringe needle is generally in the shape of a rectangular parallelepiped in sheet form, so that the third groove 12 for accommodating the syringe needle is connected to the side of the second groove 11 away from the connecting end of the first groove 10, and the cross-section thereof is rectangular, and in order to prevent the syringe needle from rotating, the depth of the third groove 12 is preferably equal to or slightly greater than one-half of the thickness of the hand-held portion of the syringe needle.

The fourth groove 13 also has two functions, one is used for accommodating an infusion catheter connected with a syringe needle, and the other is used for acting on fibers of a handheld part of the syringe needle, so that in the embodiment, the diameter of the cross section of the fourth groove 13 is smaller than the width of the cross section of the third groove 12, and the cross section is semicircular.

In addition, the groove of the upper substrate 2 may only correspond to the groove of the lower substrate 1, but the sizes of the grooves are different, for example, the groove of the upper substrate 2 has a shallow depth, the groove of the lower substrate 1 has a deep depth, and the shape of the cavity of the two covered substrates is matched with the shape and size of each part contained in the cavity.

The shape of the groove can be adjusted according to the shape of the indwelling needle, and the groove mainly prevents the heparin cap from being separated from the injection needle, so that other groove shapes can be used for achieving the purpose.

Meanwhile, in order to facilitate the transfusion, the fixator is fixed on the hand to prevent the fixator from falling off, or the fixator and the hand are fixed after the transfusion is finished to prevent the fixator from being lost.

The connection mode of the bandage 3 and the lower base plate can be direct adhesive connection, for example, the bandage is adhered to the bottom of the lower base plate by glue, but this will affect the comfort of the patient after the bandage is fixed, as shown in fig. 2, the embodiment adopts that the annular fixing buckles 14 are arranged on both sides of the lower base plate 1, and the bandage 3 is connected with the lower base plate 1 by passing through the fixing buckles 14 respectively. This kind of mode both can not influence patient's hand comfort level, and the position of infusion fixer is adjustable simultaneously.

Meanwhile, in order to be suitable for patient groups with different arm thicknesses, in the embodiment, the length of the binding band 3 is adjustable, and the adjusting mode can be as follows: the bandage 3 is an elastic bandage; the two ends of the binding band 3 are respectively connected with at least two hook sticking surfaces and loop sticking surfaces of the magic tapes which are longitudinally arranged along the length of the binding band, the binding band is annularly closed, and the annular closed length of the binding band is adjusted by adjusting the positions of the adhered magic tapes; one end of the binding band 3 is connected with two D-shaped rope buckles, the other end of the binding band can penetrate through the D-shaped rope buckles and close the binding band in an annular mode, and the double D-shaped rope buckles are buckling devices with adjusting functions.

The embodiment also provides an example of a left buckle when the upper and lower substrates are covered, the lower surface of the left side of the upper substrate 2 is vertically connected with the buckling part 20, the inner surface of the buckling part 20 is transversely provided with a first clamping strip 200, and the left side of the lower substrate 1 is vertically connected with a second clamping strip 15, which is used for clamping when the upper substrate 2 is covered with the lower substrate 1, so as to prevent the two from being separated. Other buckling modes, such as buckling and locking, can also be realized, which is the prior art and is not described herein again.

In this embodiment, the upper substrate 2 and the lower substrate 1 are made of medical plastic or resin, and may have a rectangular parallelepiped shape with rounded corners.
