Description

Injector booster

This utility model relates to a kind of medical auxiliary implement, further is medical injection needle tubing booster.

China's utility model patent the 4th phase of communique, the 39th volume disclose a kind of medical needle tubing booster: " syringe pressurization booster "--application number: 87211014, the applying date: 87.7.26, international classification number: A61M5/24.Its objective is to solve and infuse to patient injection with big needle tubing, during the bigger glucose of for example defeated viscosity, the problem that the pipe of pushing pin is very required great effort; Its formation is that a carriage is arranged, and the carriage front end has the arc gap for the widening pipe, and there is a hole carriage rear end, and silk is equipped with leading screw in the hole, and the leading screw rear end has small handwheel, rotates small handwheel, and leading screw is advanced along the silk hole, promotes pintle; Its weak point is that needle tubing needs to use inconvenience with holding on carriage, and the leading screw head withstands on the pintle tail end and rotates, and has strengthened booster length.

Purpose of design of the present utility model is to avoid above-mentioned weak point of the prior art and provides a kind of operation nimble, and reliable and stable, volume is small and exquisite, portable needle tubing booster.

The purpose of this utility model can reach by following measure:

Carriage is being arranged, be positioned on the leading screw on the carriage, the carriage front end has the arc gap for the widening pipe, the leading screw tail end has on the medical needle tubing booster of small handwheel, the fixed part (15) of carriage front end band arc gap top is added one constitute the movable part (13) that the needle tubing card blocks (1) with this one, movable part (13) one sides have upwarp, a confession moving passeris montani saturati tail (14) of finger plate, in this side the one little axle that movable part (13), fixed part (15) are linked is mutually arranged, and force movable part (13) to be fastened on spring on the fixed part (15).

The purpose of this utility model can also reach by following measure:

The opposite side of the little axle of the fixed part of needle tubing booster (15) band hinge joint is equipped with the padlock that pins movable part (13).

The structure of padlock is blocked (1) dehisce tongue (23) of side for being fixed on fixed part (15), card, tongue (23) middle part riveting has a columniform locking bolt (17), locking bolt (17) front end is whittled into an inclined-plane from top to bottom, it is through in the vestibule of platform wall, chamfered portion protrudes outside the wall, and inserts in the hole of movable part (13) corresponding position.

Making movable part (13) be fastened on spring on the fixed part (15) on the needle tubing booster is one to be contained in little axle intermediary torsion spring (2).

Leading screw on the needle tubing booster (10) is positioned at a side of needle tubing.

There is fulcrum at the two ends of the leading screw on the needle tubing booster (10), have on the leading screw (10) along the axially movable nut of leading screw (9), and the push pedal (4) of the pipe of pushing pin is arranged on the nut (9).

This utility model is done further to comment below in conjunction with accompanying drawing:

Fig. 1: the needle tubing booster comprises propelling driving section and needle tubing fixed part two parts.Advance the driving section to form by sleeve pipe 11, leading screw 10, nut 9, push pedal 4 and handwheel 7.The sleeve pipe 11 here is a carriage, and its upside has a sliding tray, and flute length is greater than propelling stroke, and there is a rectangular boss nut 9 tops, and this boss is contained in the chute of sleeve pipe 11 upsides.When leading screw 10 rotates under the drive of handwheel 7, the chute of nut 9 with matching on the sleeve pipe 11 moved forward or backward, push pedal 4 is because of being fixed on the boss of nut 9 with two counter-sunk screws 5, so push pedal 4 just promotes pintle and moves forward.Because leading screw 10 is the two ends point supporting, nut 9 moves along the chute on the sleeve pipe, does not have relative motion between push pedal 4 and the pintle, and therefore, progradation is very steady.This transmission, leading screw rotates and does not move, and leading screw does not stretch out outward, and the kind of drive that entire length moves than leading screw has reduced one and has moved length outward, so the little compactness of body.

Fig. 2,3,4: body 19 upsides that sleeve pipe 11 is shown have a chute, are welded with a bearing 20 in the left end, are welded with a baffle plate 16 outward, with the fixing usefulness of blocking of blocking, right-hand member is welded with a backplate 18, and its effect has two: one, and the bottom is drilled with three holes, with the fixing usefulness of block plate 8; The 2nd, when booster lies in the propelling of the first-class place of bed, can may not be obstructed because of pintle touches other object in top.Because of the last wide size of backplate 18 is bigger than the external diameter of pintle tail flange, played supporting role.Leading screw 10 right-hand members have a platform that diameter is bigger than major diameter of thread, outer again is the spindle nose of a diameter less than round platform, spindle nose is with block plate 8, there are three with screw 22 both to be fixed together on the block plate 8 with 18 corresponding holes of backplate, the spindle nose dress handwheel 7 of leading screw 18, with dog screw 21 the two is fixed as one, as shown in Figure 5.

Fig. 6,7: the structure that shows nut 9.

Fig. 8～11: show the standing part of needle tubing, it is that the card of an energy opening blocks 1, and be divided into two parts up and down: top is movable part 13, and the bottom is a fixed part 15, and fixed part 15 is fixed on the baffle plate 16 of sleeve pipe 11 right-hand members by three screws 12.One side of movable part 13 has a passeris montani saturati tail 14, and lower end and fixed part 15 are connected with hinge, in the middle of the little axle of hinge a torsion spring 2 are housed.Open card and block 1 when putting into needle tubing, available finger is pulled passeris montani saturati tail 14 downwards, and movable part 13 is that axis rotates with the little axle of hinge just, card is blocked open, and after needle tubing is put well, unclamps passeris montani saturati tail 14, and movable part 13 just leans on the elastic force of torsion spring 2 that it is closed.At opposite side a padlock is housed, when movable part 13 closes, clicks downwards gently with finger, can be with upper and lower two parts locking, needle tubing promptly is stuck.

The concrete structure of padlock is: the side of dehiscing of blocking 1 fixed part 15 at card, protrude a higher platform, there is a upright elongated slot in the outside of platform, interior dress tongue 23, tongue 23 bottoms are fixing with two screws 24, the middle part riveting has a columniform locking bolt 17, and the front end of locking bolt 17 is whittled into an inclined-plane from top to bottom.Locking bolt 17 is through in the vestibule of platform wall under the normal condition, and chamfered portion protrudes outside the wall, in movable part 13 corresponding positions a hole is arranged, its diameter is a bit larger tham locking bolt 17 diameters, when the chamfered portion of locking bolt 17 inserts in this hole, block movable part 13 and can not open, promptly be referred to as meaning and pinned.Open movable part 13, applying finger is outwards pulled tongue 23, makes locking bolt 17 withdraw from the corresponding aperture of movable part 13, and pulling again, passeris montani saturati tail 14 gets final product.Card blocks 1 when closing, and clicks movable part 13 with hands, forces locking bolt to retreat, and mating holes insertions of rebounding again is with movable part 13 pinnings.

Card blocks 1 and handwheel 7, can make of cast aluminium, also can make of duroplasts.The whole appearance of booster can be plated one deck chromium, but also spraying plating one deck plastics.Make it smooth, attractive in appearance, durable.

This needle tubing booster can be held with hands when advancing, and also can keep flat in bed, on the tables and chairs, and is flexible and convenient to use.
