Description

Infant transfusion hand regulator

Technical field

This utility model belongs to the technical field of medical treatment and nursing utensil, is specifically related to a kind of infant transfusion hand regulator.

Background technology

In infant transfusion process, because infant lacks self-control, hand is often touched, even also can be owing to crying and screaming, uncomfortable etc. former thereby clench one's fists in spite of oneself, and cause blood vessel to be squeezed, cause blood (medicinal liquid) constricted flow.For this reason, people have designed a kind of infant transfusion hand regulator, it structurally comprises rigid substrates, finger-stall, movable hasp three parts, the wherein shape of rigid substrates and the form fit of hand, finger-stall is arranged on the front upper surface of rigid substrates, and movable hasp is arranged on the rear upper surface of rigid substrates.

During use, the finger of infant and palm stretching, extension are kept flat above rigid substrates, finger stretches in finger-stall simultaneously, the fixing binding of utilization activity hasp of the position, boundary of palm and wrist.Like this, the hand of infant is just fixed, and finger and palm are forced to keep flattening, and no longer can clench one's fists, and guarantee to infuse smooth and easy.

Yet, because infusion process reaches several hours even tens hours, if allow infant hand keep above-mentioned stiff posture always, lack move place, not only there is no need, and really can cause infant very uncomfortable hard to bear.

Utility model content

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of infant transfusion hand regulator is provided, and it can guarantee to infuse smooth and easy, can make again infant feel pleasant.

Its object can realize by following scheme: this infant transfusion hand regulator comprises rigid substrates, finger-stall, movable hasp, wherein finger-stall is arranged on the front upper surface of rigid substrates, movable hasp is arranged on the rear upper surface of rigid substrates, its main feature is, described rigid substrates comprises prebasal plate and metacoxal plate two parts that split arranges, and utilizes the rotating shaft of a horizontal expansion to be articulated between prebasal plate and metacoxal plate; Metacoxal plate is also provided with make progress the first limited block, the restriction prebasal plate of rotational angle range of restriction prebasal plate and rotates the second limited block of angular range, and prebasal plate can rotate in the angular range that the first limited block and the second limited block limit; Between prebasal plate and metacoxal plate, be also provided with torque spring, under the twisting force of torque spring, conflict under normal conditions the first limited block of metacoxal plate of prebasal plate, and prebasal plate and metacoxal plate keep straight.

Metacoxal plate is movable rotation within the scope of 35 ° that limit between the first limited block and the second limited block～50 °.

The utlity model has following advantage and effect:

When this utility model is used, child's finger is put into the finger-stall above prebasal plate, palm is placed on above metacoxal plate, and with movable hasp, palm is bound, thereby the hand of infant is fixed, and under normal conditions, torque spring can make prebasal plate and metacoxal plate keep straight, make finger and palm keep flattening posture, so that transfusion swimmingly.And in transfusion after certain hour length, if infant thinks that hand posture is not in good time, the infant active bending hands of can exerting oneself at short notice refers to, thereby overcome the torsion of torsion spring, allow prebasal plate rotate around the shaft certain angle (being less than 35 °～50 °), finger can be bent downwardly for metacarpus by transitory phase, to alleviate discomfort, after the sense of discomfort feel of infant is eased, infant hand naturally and understandably can loosen again, hand is exerted oneself no longer consciously, so under the twisting force of torque spring, prebasal plate and metacoxal plate automatically restore to again the posture of flattening, finger and palm keep again flattening.

In a word, the utlity model has following four aspect features: (1). within the most of the time, can keep palmar hand and finger to flatten, guarantee to infuse smooth and easy; (2). between the front and rear part of rigid substrates, there is certain elasticity, flexibility, flexible, allow that palmar hand and the finger short time within the scope of certain angle is crooked, to alleviate the uncomfortable hard to bear degree of infant; (3). between the front and rear part of rigid substrates after crooked certain hour, for example, child's unconscious firmly time (sleep or firmly time), can automatically recover again to flatten; (4). no matter child is under comfortable or uncomfortable state, can stops infant to be made to clench one's fists and wait the significantly action that surpasses tolerance limit, anti-hemostatic tube is significantly pushed, so can not affect normally carrying out of transfusion.

The specific embodiment

Shown in Fig. 1, this infant transfusion hand regulator comprises rigid substrates, finger-stall 21, movable hasp 22, described rigid substrates comprises prebasal plate 11 and metacoxal plate 12 two parts that split arranges, and utilizes the rotating shaft 13 of a horizontal expansion to be articulated between prebasal plate 11 and metacoxal plate 12; Metacoxal plate 12 is also provided with make progress the first limited block 31, the restriction prebasal plate of rotational angle range of restriction prebasal plate and rotates the second limited block 32 of angular range, prebasal plate is provided with locating piece 33, the locating piece 33 of prebasal plate can rotate within the scope of 35 ° that limit between the first limited block 31 and the second limited block 32 in activity, and therefore whole prebasal plate 21 also can 13 rotate around the shaft in this angular range; Between prebasal plate 11 and metacoxal plate 12, be also provided with torque spring 14, under the twisting force of torque spring 14, the locating piece 33 of prebasal plate the first limited block 31 that metacoxal plate is conflicted under normal conditions, and prebasal plate 11 and metacoxal plate 21 both keep straight.Finger-stall 21 is arranged on the upper surface of prebasal plate 11, and movable hasp 22 is arranged on the upper surface of metacoxal plate 12, and the employing VELCRO of the both wings of movable hasp 22 is flexibly connected.

Shown in Fig. 2, Fig. 4, when this utility model is used, child is pointed to 41 finger-stalls 21 of putting into above prebasal plate, palm 42 is placed on above metacoxal plate 42, and with movable hasp 22, palm 42 is bound, thereby the hand of infant is fixed, under normal conditions, torque spring 14 can make prebasal plate 11 and metacoxal plate 12, and both keep flattening, and make its finger 41 and palm 42 keep flattening, smooth and easy to guarantee to infuse.

In transfusion after certain hour length, if infant thinks that hand posture is not in good time, the infant activity of can exerting oneself at short notice points 41, thereby overcome the torsion of torque spring 14, promote prebasal plate 11 and rotate around the shaft certain angle, so finger 41 can be bent downwardly for metacarpus 42 by transitory phase, as Fig. 3, shown in Fig. 5, to alleviate discomfort, after the sense of discomfort feel of infant is eased, infant hand naturally and understandably can loosen again, hand is exerted oneself no longer consciously, so under the twisting force of torque spring 14, prebasal plate and metacoxal plate automatically restore to again the posture of flattening, finger and palm keep again flattening.

The prebasal plate activity point of view scope limiting between above-mentioned the first limited block and the second limited block can change 40 ° into, or is 50 °.
