Abstract

The utility model discloses an air-operated fixed quantity blood collecting balance, which is a product of medical appliance. The utility model is characterized in that a base is made by an oblong shape aluminium plate, a column is fixed on one end of the base, a lever is made of flat steel, passing through the center of the upper part of the column. The lever is fixed by a feed-through shaft. A pallet is divided into upper and lower layers, and the middle of the two layers is provided with an air-operated telescopic air bag. A blood donor pinches a balloon to produce a power by means of braking and mixing, main and auxiliary specially made springs are quantitatively used to pass through the lever to be adopted. An elastic force trigger is used to automatically cut off blood flow. A 5 type battery is used as a power supply in an indicator light and a warning alarm device. The utility model has the advantages of simple structure of entire machine, accurate quantification, and wide range, and five stops are arranged in the utility model. The utility model can automatically cut off the blood flow, being conveniently and safely used.

Description

Air-operated fixed quantity blood collecting balance

Present technique belongs to medical instruments field.

Domestic blood stations at different levels, hospital blood bank blood sampling at present weighs with scale more, and manual swing mixes blood.Electronic blood sampling title, electronic digital display blood sampling claim, can both reach the purpose of swing mix homogeneously, but quantitative error are big, class is few, between every 800-1000 unit of price, therefore are difficult to promote.

The purpose of this utility model be development a kind of simple in structure, quantitatively accurately, mix homogeneously, blood sampling safe in utilization, occlude blood automatically claim, realizes more than 1,000 ten thousand person-times blood sampling work modernization in China's every year.

This utility model structure as shown in Figure 1 and Figure 2.Pneumatic quantitative blood sampling claims to be made up of critical pieces such as base, column, lever, pallet, the gentle pressure balls of proportioning device.

Base 1 is made by long 200 * wide by 150 * thick 6 millimeters aluminium sheets.Principal post 2 is fixed on an end of base, is made by long 40 * wide by 25 * high 250 millimeters special-shaped aluminium tube materials.Lever 3 is made by 3 * 20 long 200 millimeters band steels, is loaded on the column center upper portion and passes, and is fixed by a punching axle.Pallet 4 is made by long 210 * wide by 110 * high 20 millimeters aluminium alloys, and is two-layer about dividing, and the upper strata dish can be up and down, in two-layer centre pneumatic extension airbag bag is housed, and is used to swing blood.Quantitative spring is a special φ 9 long 40 millimeters spring, graduated scale, the quantitative proportioning devices formed of leading screw, and the upper end of spring connects the lever back, and the spring lower end is connected with the adjustable quantitative leading screw, is installed in the column back side, and it is quantitative to move up and down adjusting.Pneumatic means 6 is made up of a rubber bulb, 3 * 4 plastic catheter and plastic gas bag bag, and gasbag is loaded in the middle of the blood sampling pallet, and rubber bulb is held by the blood donor and inflated, so as to swing blood sampling pallet.Automatic flow-stop 7 is made up of a reaction spring, trigger, hook, is connected the place ahead on the horizontal hanger.Blood sampling beginning hook is with the pull-up of spring trigger, and blood flow can enter the blood bag by conduit, and whenever the lever position (to quantitatively) that is up to the standard, hook can be thrown off, and trigger returns clamps conduit, and blood flow stops.Quantitative siren 8, display lamp 1.5V unidirectional current is loaded on the column top, siren (sound closes) is loaded under the bedplate, divides line traffic control, when blood when quantitative, the lever position that is up to the standard.Controller 9 contacts with alarm 10, and display lamp is bright, promptly rings as the excess siren.

Claims

1, pneumatic quantitative blood sampling claims, it is characterized in that base, is made by a rectangle aluminium sheet, and column is fixed on an end of base, and lever is made by band steel, passes from the column center upper portion, is fixed by a punching axle; Pallet divides two-layer up and down, is loaded on the lever front end, and pneumatic extension airbag bag is housed in the middle of two-layer dish, and the lever tail end is equipped with a special quantitative spring, graduated scale, quantitative screw mandrel etc. to be adjusted and the control proportioning device; Pneumatic means connects gasbag by a rubber bulb with plastic catheter and forms, and is used for swing and mixes blood; The automatic flow-stop device adds trigger by a bounce-back spring and constitutes, and is loaded on pallet front end blood sampling conduit by the place, is used for automatic flow-stop blood; Siren is loaded on the column top, can indicate when blood reaches quantitative.

2, described pneumatic quantitative blood sampling claims according to claim 1, it is characterized in that base 1, is made by the thick 6 millimeters aluminium sheets of the wide 150* of long 200*.

3, according to claim 1, pneumatic quantitative blood sampling claims, it is characterized in that column 2, is fixed on an end of base, is made by the high 250 millimeters special-shaped aluminium tubes of the wide 25* of long 40*.
