Definitions

  • This invention relates to pressure infusion apparatus for the controlled delivery of fluid to an ambulatory patient, such as the victim of a road accident or a casualty in battle who immediately requires an intravenous drip.
  • the invention provides pressure infusion apparatus for an ambulatory patient comprising a flexible liquid bag connected to an output tube for administering the liquid to the patient, a flexible pressure bag held next to the liquid bag for pressurising the liquid by squeezing the liquid bag, means for inflating the pressure bag, means for monitoring the pressure it applies to the liquid, and a shoulder cushion adapted to support and to retain the liquid bag and pressure bag securely above the cushion and comfortably over one of the patient's shoulders, the cushion having means for holding it releasably in place over the patient' s shoulder.
  • the cushion extends over both the patient' s shoulders and around the back of his neck, such that a further assembly comprising a similar pressure bag and liquid bag can be supported over his other shoulder to balance that over the first-mentioned shoulder.
  • the cushion is inflatable and deflatable for portability and compact storeability, and to reduce to a minimum the weight borne by the patient in use.
  • the outlet tube may comprise an intravenous drip-feed or a catheter, to suit the medical requirement; different fluids may be dispensed in different ways to respective parts of the patient' s body from liquid bags held over resOective shoulders.
  • the monitoring means provides an indication when the pressure drops below a predetermined threshold, so that the inflating means may be activated, manually or by some other means which may respond automatically to the indication.
  • the liquid bag is disposable, and the shoulder cushion retains the liquid bag and pressure bag releasably so that the liquid bag may be replaced.
  • Figure 1 is a perspective view of pressure-induced drip-feed apparatus in place over a patient' s right shoulder;
  • Figure 2 is a perspective view corresponding to Figure
  • Figure 3 is an enlarged perspective view of the cushion of the apparatus illustrated in Figures 1 and 2;
  • Figure 4 is a greatly enlarged perspective view of a drip-feed metering device used in the apparatus shown in
  • the intravenous drip-feed apparatus comprises a cushion 10 strapped over a patient's shoulders, a sealed liquid bag 20 containing the appropriate fluid such as plasma or saline, and connected to an outlet for administering the liquid, and a pressure bag 30 connected to means for inflating it and for monitoring its pressure.
  • the cushion 10, shown most clearly in Figure 3, consists of an inflatable U-shaped envelope, and resembles inflatable neck cushions obtainable for the comfort of passengers who wish to sleep during journeys.
  • the cushion is preferably of fire-proof material such as nylon. When deflated by means of a valve (not shown), it may be folded for compact storage.
  • the cushion has portions which rest comfortably over each shoulder, the upper surface of each such portion having a smoothly-contoured recess 13, 14 for accommodating the combination of the pressure bag 30 and the liquid bag 20.
  • Each such portion has a pair of parallel retaining straps 15, 16 for releasably retaining the respective assembly 20, 30; in this example, each strap is in two parts releasably connectable by Velcro (trade mark) textile material with frictional engagement.
  • the cushion 10 is held in place over the patient' s shoulders by means of diagonal shoulder straps 17, 18 with quick-release couplings in the form of interlocking male 19M and female 19F couplings.
  • Adjacent one end of each recess 13, 14 is a respective peg 11, 12 for hanging the liquid bag from the flexible loop which is conventionally provided at the edge of the bag (22, Figure 2; not shown in Figure 1).
  • the liquid bag 20 has an outlet tube 21 connected to a drip counter and non-return valve arrangement 60 which is transparent and which prevents embolism occurring. This in turn is connected by tubing through a roller valve 61, for reducing or shutting off the flow, to a needle 70 which, in use, enters the patient' s vein.
  • the ultimate outlet usually in the patient' s arm, is lower than the height of the liquid bag 20 when the patient is ambulatory, so that there is a differential pressure due to gravity in addition to that due to the pressure bag 30.
  • the pressure bag 30 consists of a generally rectangular envelope with an end tab 31 of reduced width, which in use is wrapped twice around the liquid bag 20.
  • the inner surface of the end tab 31 is adhered to the underlying portion of the bag, in this example by means of Velcro strips 32. It is thus releasable for the replacement of the liquid bag 20.
  • the interior of the envelope of the pressure bag 30 communicates with both a pressure valve 40 with a readable pressure scale, and a manual air pump bladder 50 by way of tubing 35 and a non-return valve 34.
  • the shoulder cushion 10 is inflated and strapped over the patient, and at least one, possibly two assemblies consisting of liquid bag 20 and pressure bag 30 are strapped over a respective shoulder or shoulders.
  • the bladder 50 is then pumped until the pressure bag 30 expands, squeezing the liquid bag 20, to reach at least a predetermined minimum threshold pressure, as indicated on the pressure gauge 40. Because of the contiguity over flexible surfaces of the pressure bag 30 and the liquid bag 20, both of which have flexible walls, the pressure indicated on the pressure gauge 40 is close to the pressure within the liquid contained in the liquid bag 20.
  • the intravenous drip is then inserted in the usual way by the medical practitioner. The patient may then be left without the need for constant supervision; periodic checking of the pressure should be exercised, and the pressure bag 30 reinflated when necessary. This monitoring process is simplified by the provision of a coloured region on the pressure gauge face indicative of pressures below the predetermined threshold.
  • the pressure gauge 40 may incorporate an automatic alarm providing a visual or aural warning when the pressure drops below the threshold.
  • this indication may be provided automatically to an automatic pressure-applying means, such as an electrically-controlled valve controlling the outlet from a pressurised gas canister, or an electric air pump, provided in addition to, or instead of, the manual bladder 50.
  • the liquid bag 20' is shorter, and has a loop 22 clearly visible for supporting it over the corresponding peg 12.
  • the pressure bag 30' consists of a rectangular pressurised envelope 36 connected to a single-layer webbing 37, together forming a pocket for holding the liquid bag 20' .
  • the pressurised envelope 36 is connected to the bladder 50 by way of a valve 34' which is capable of being turned so as to release the air from the bag 36.
  • the pressurised envelope 36 is also connected by way of flexible tubing to a pressure gauge 40' , conveniently placed for the patient to read the pressure himself.
  • the pressurised envelope 36 When the pressurised envelope 36 is inflated in use, the liquid bag 20' is squeezed between the envelope 36 and the webbing 37, so that the air pressure is transmitted through the flexible walls to the liquid in the liquid bag 20' .
  • a proprietary drip-metering dial valve 62 shown more clearly in Figure 4, is provided in the tubing between the non-return valve 60 and the drip-feed needle 70, either in addition to, or instead of, the roller valve 61.
  • This valve 62 has fixed 64 and movable 63 portions arranged such that the required drip rate may be set on a rotary scale 65; in this example, the scale is indicated as the number of drips per minute.
