Abstract

The elastically extruding infusion set includes a box body, a box cover, an upper soft pad, an infusion bag, a lower soft pad, a floating board, a locking structure and elastically extruding mechanisms. The upper soft pad is fixed to the lower side of the box cover, three or more elastically extruding mechanisms in the same structure are installed inside the box body to act on the lower side of the floating board synchronously, the lower soft pad is fixed on the upper side of the floating board, the box cover is hinged to the box body for easy opening, and the infusion bag is set between the upper soft pad and the lower soft pad. Under the synchronous action of the elastically extruding mechanisms, the floating board is pushed upwards at constant force to ensure homogeneous infusion pressure and fluid exhaustion. The present invention is especially suitable for field use.

Description

Elastically extruding infusion set

Technical field:

The present invention relates to a kind of medical apparatus, relate in particular to a kind of device that utilizes impressed pressure to infuse.

Background technology:

At present, when infusing, all must use disposable transfusion device to the human or animal, well-known existing disposable transfusion device all utilizes height pressure reduction principle to infuse, transfusion bag (bottle) is suspended on eminence, the feed tube of transfusion device communicates with transfusion bag (bottle), the drain pipe of transfusion device communicates with the vein of human body (or animal), between feed tube and drain pipe, be provided with and drip fast control valve, between the outlet of transfusion bag and drain pipe certain drop must be arranged, this suspension type infusion model is widely used in hospital, clinics etc. have the fixed-site of transfusion condition, but operation in the open air, earthquake relief work, then be difficult in the mobile rescue such as battlefield use, use and just must make transfusion bag (bottle) be higher than human body, service condition is higher, not only use inconvenient, and be easy to incur loss through delay rescue period, therefore press for a kind of hanging infusion set of exempting from.

Summary of the invention:

Goal of the invention of the present invention is to provide a kind of elastically extruding infusion set, uses this extruding infusion set, and transfusion bag need not to be suspended on eminence, and infusion pressure remains stablely in infusion process, and is easy to carry.

The technical solution used in the present invention is: it comprises lid, last cushion, transfusion bag, following cushion, float plate, locking mechanism, elastic force pressing mechanism and box body, the described cushion of going up is fixed on the lower surface of lid, the elastic force pressing mechanism of three above same structures is installed in the box body symmetrically, synchronously act on the lower surface of float plate, following cushion is fixed on the upper surface of float plate, syndeton for opening or closing between lid and the box body, transfusion bag is placed between cushion and the following cushion.

Described elastic force pressing mechanism is made up of dwang, roller, connecting rod, sliding shoe, sliding rail and spring, the lower end of dwang is hinged on the sliding rail, but be installed in to the roller rotation upper end of dwang, connecting rod one end and dwang are hinged, the other end and sliding shoe are hinged, spring places in the sliding rail, and is sleeved on the central spindle of the spring of sliding shoe.

Described elastic force pressing mechanism is made up of spring guide holder, setting spring, and the spring guide holder is fixed in the box body, erects spring and is placed on the spring guide holder.

Described lid with the syndeton that opens or closes between the box body is: lid is linked to each other by hinge on one side with box body, is provided with locking mechanism at opposite side, and described locking mechanism is forced bayonet arrangement or hasp structure.

Using method of the present invention is as follows:

Open the lid, transfusion bag is placed between cushion and the following cushion, transfusion bag communicates with the feed tube of disposable transfusion device, closes to drip fast control valve, with lid and box body closure, carries out normal infusion by the transfusion requirement then.

Because transfusion bag is placed between lid and the box body, the end face of transfusion bag is close to the last cushion in the lid, the bottom surface is oppressed by float plate, float plate forces the float plate constant force that makes progress to be passed by four uniform elastic force pressing mechanisms, thereby the suffered squeeze pressure of transfusion bag is uniform, this is to keep the basicly stable basis of infusion pressure, owing to be provided with cushion on the lower surface of lid, on float plate, be provided with cushion down, float plate and lid lower surface are the plane, transfusion bag is placed between two planes, can up hill and dale the liquid in the transfusion bag be extruded emptying in the process of moving on the float plate level.This extruding infusion set is particularly suitable for the mobile rescue of particular places such as field work, earthquake relief work, battlefield, can realize accessible transfusion, this elastically extruding infusion set transfusion need not other additional conditions, volume is little, be easy to carry, and infusion pressure is even, and discharge opeing is thorough, is the desirable supporting using appliance of disposable transfusion device.

The specific embodiment:

Illustrate the specific embodiment of the present invention below in conjunction with Figure of description:

Embodiment 1:

Elastically extruding infusion set of the present invention such as accompanying drawing 1, shown in Figure 2, it comprises lid 1, last cushion 2, transfusion bag 3, following cushion 4, float plate 5, locking mechanism 6, elastic force pressing mechanism 7 and box body 8, the described cushion 2 of going up is fixed on the lower surface of lid 1, four elastic force pressing mechanisms 7 are installed in the box body 8 symmetrically, and be positioned at the below of float plate 5, following cushion 4 is fixed on the upper surface of float plate 5, syndeton for opening or closing between lid 1 and the box body 8, transfusion bag 3 is placed between cushion 2 and the following cushion 4.Described elastic force pressing mechanism 7 is made up of dwang 71, roller 72, connecting rod 73, sliding shoe 74, sliding rail 75, spring 76, the lower end of dwang 71 is hinged on the sliding rail 75, but be installed in to roller 72 rotations the upper end of dwang 71, one end and the dwang 71 of connecting rod 73 are hinged, the other end and sliding shoe 74 are hinged, and spring 76 places in the sliding rail 75 and is sleeved on the central spindle of the spring of sliding shoe 74.Described lid 1 is linked to each other by hinge 9 on one side with box body 8, is provided with locking mechanism 6 at opposite side, and described locking mechanism 6 is a hasp structure.
