Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

For conveniently understanding the utility model provides an elbow device for outpatient bloodletting that embodiment provides, the first description is the application scene that is used for outpatient bloodletting's elbow device that this application embodiment provided, the elbow device for outpatient bloodletting that this application embodiment provided for outpatient bloodletting, be used for outpatient bloodletting in-process, make patient's arm put the position of bloodletting and place and fix, and at the bloodletting in-process at present, the cushion that outpatient clinic used is not convenient for patient to put the position of bloodletting well usually, moreover, there is the circumstances that dizzy needle exists in the process of bloodletting in patient often, and the cushion that current outpatient clinic used can not accomplish the emergence of avoiding patient's dizzy needle. To this end, the present application provides an elbow device for outpatient blood drawing to solve the above-mentioned problems. The following detailed description is made with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an elbow device for outpatient blood drawing according to an embodiment of the present invention.

As shown in fig. 1, the elbow device for outpatient blood drawing comprises a base plate 1, wherein the base plate 1 is overall in a slope shape and is tapered along the extension direction of the slope, and the cross section of the base plate 1 is in a trapezoid shape. Be provided with undercut at bed plate 1 top and be curved arm recess 2, be provided with the cushion in the arm recess 2, and be provided with undercut on the cushion and be oval-shaped elbow recess 3.

In this embodiment, arm recess 2 is used for placing patient's arm, and bed plate 1 is whole to be slope form, and during the placement, higher one side is towards the patient, helps patient's arm to set the position of drawing blood, and lower one side is towards the doctor to bed plate 1 follows slope extending direction toper shrink, and the doctor of being convenient for draws blood to patient's arm. The cross section of the base plate 1 is trapezoidal, which is helpful for enhancing the placing stability of the base plate 1 when the base plate 1 is placed. Be provided with the cushion in arm recess 2, the travelling comfort when guaranteeing patient's arm and putting the elbow recess 3 that sets up on the cushion then can make patient's arm elbow be located wherein, reduces the possibility that patient's arm removed.

Further, a placement groove 7 for placing a tourniquet is further arranged on the soft cushion layer, and the placement groove 7 stretches across the soft cushion layer. The tourniquet is being placed to the recess 7 of placing that sets up, ties the tourniquet on patient's arm, and when patient's arm placed in arm recess 2, the tourniquet of system on patient's arm is accomodate in placing recess 7, avoids making patient's arm put not level in arm recess 2 because of the reason of tourniquet, helps guaranteeing the travelling comfort of patient's arm when placing in arm recess 2.

In addition, the cushion layer is the sponge cushion layer, and the travelling comfort when guaranteeing patient's arm and putting in arm recess 2 simultaneously the surface of cushion layer is provided with antibiotic layer, antibiotic material on antibiotic layer is the antibiotic polymer material that patent number is disclosed in 200610148043.X, and it has anticorrosive antibiotic effect, through antibiotic layer plays long-term antibiotic effect.

With continued reference to figure 1, the present application also provides an elastic strap 8 on top of the base plate 1 for securing the arm. When specifically setting up, 8 one ends of elastic webbing and 1 top one side fixed connection of bed plate, the inboard surface of the 8 other ends of elastic webbing is provided with magic tape matt surface 9, simultaneously sets up at 1 top opposite side of bed plate and pastes hook and loop surface 10 with magic tape matt surface 9 matched with magic. Patient's arm is put in arm recess 2, drags tight elastic webbing 8, makes magic on the elastic webbing 8 paste hair side 9 and the magic at 1 top of bed plate and pastes collude face 10 and glue together to fix patient's arm through elastic webbing 8, avoid drawing blood in-process patient's arm to take place the displacement.

Referring to fig. 2 and 3, fig. 2 is a cross-sectional view of a base plate provided in an embodiment of the present invention when a baffle is located in a receiving groove, and fig. 3 is a cross-sectional view of a base plate provided in an embodiment of the present invention when a baffle is extended out of a receiving groove.

As shown in fig. 2 and 3, the two sides of the base plate 1 are respectively provided with an open storage groove 4, it should be noted that the two storage grooves 4 are parallel to each other, but are not communicated with each other, and each storage groove 4 is internally provided with a baffle 5, the baffle 5 can slide in the storage groove 4, and meanwhile, each baffle 5 is provided with an exposed limiting plate 6, the width of the limiting plate 6 is greater than the cross-sectional width of the baffle 5, the limiting plate 6 plays a limiting role, the two are fixedly connected with each other, and the baffle 5 can be pulled out from the storage groove 4 through the limiting plate 6.

In addition, magnets are respectively arranged on the two limiting plates 6, the magnets are specifically embedded in the limiting plates 6, and the magnets on the two limiting plates 6 can attract each other. Baffle 5 and the semicircular structure who accomodates groove 4 for the looks adaptation, can accomodate 4 internal parts in grooves and pull out two baffles 5 respectively through two limiting plates 6, when pulling out baffle 5, two limiting plates 6 can be close to each other, and can at least partly coincide, and magnet on two limiting plates 6 attracts each other again when two limiting plates 6 are close to each other, thereby make two limiting plates 6 paste tight link together, two baffles 5 then constitute a more great semicircular structure, can block the sight that the patient watched elbow position of bleeding department, thereby the patient that makes the dizzy needle of easy dizzy blood avoids taking place the phenomenon of dizzy needle. The two baffle plates 5 are also at least partially positioned in the accommodating grooves 4 when the two limiting plates 6 are tightly connected together.

In another preferred embodiment, two L-shaped position-limiting plates 6 are respectively arranged, the two L-shaped position-limiting plates 6 are in the state shown in FIG. 4 when they are close to each other, the two position-limiting plates 6 are closely connected together under the action of the attraction of the magnets, and the arrangement is easier to pull the baffle 5 out of the accommodating groove 4 through the position-limiting plates 6. The two baffle plates 5 are also at least partially positioned in the accommodating grooves 4 when the two limiting plates 6 are tightly connected together.

In the above embodiment, in order to prevent the baffle 5 from completely falling out of the accommodating groove 4, an elastic rib may be further disposed in the accommodating groove 4, and the innermost end of the accommodating groove 4 and the inner end of the baffle 5 are connected by the elastic rib, so that the baffle 5 can be prevented from being completely pulled out to a great extent.

When not using baffle 5, with the separation of two limiting plates 6, because baffle 5 is the semicircular structure, in addition the elastic action of elasticity muscle can make baffle 5 automatic recovery accomodate groove 4 in addition, limiting plate 6 then spacing card is at the opening part of accomodating groove 4. Furthermore, a rubber layer can be wrapped on the limiting plate 6 to reduce the impact force of the limiting plate 6 on the base plate 1 when the baffle 5 is recovered in the accommodating groove 4.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
