Abstract

Infusion apparatus comprising an infusion bag 1 and an infusion line 2 which is normally attached to the latter in a non-releasable manner and which receives, as seen in the direction from the infusion bag, a contact pin 3 and flow indicator, a clamp 4 and a check valve 5, preventing return flow to the infusion bag 1, and an infusion needle 6 which is secured at the free end of the line 2 and is protected in a known manner by a removable needle guard. <IMAGE>

Description

467 951 ~ å' 2 10 15 20 25 30 35 40 ventilen 5 visas närmare i figur 4 och har i princip formen av en slangdel av exempelvis silikon, tillplattad vid ena änden 9. 467 951 ~ å '2 10 15 20 25 30 35 40 the valve 5 is shown in more detail in figure 4 and has in principle the shape of a hose part of for instance silicone, flattened at one end 9.

Slangmaterialet avsmalnar mot denna ände och bildar där två mycket tunna läppar, vilka normalt anligger mot varandra. Vid ett flöde från höger, sett i figur 4, kommer läpparna att skiljas åt och tillåta fritt flöde. I det fall trycket till vänster om backventilen skulle bli högre än trycket till höger om ventilen, kommer läpparna automatiskt att tillsluta spalten däremellan, hindrande ett flöde från vänster i figuren. Back- ventilen är anordnad i en till infusionsslangen 2 ansluten rördel 10.The hose material tapers towards this end and there forms two very thin lips, which normally abut each other. At a flow from the right, seen in Figure 4, the lips will separate and allow free flow. In the event that the pressure to the left of the non-return valve should be higher than the pressure to the right of the valve, the lips will automatically close the gap therebetween, preventing a flow from the left in the figure. The non-return valve is arranged in a pipe part 10 connected to the infusion hose 2.

Figur 3 visar schematiskt brytstiftet 3 i sin röranslut- ning 11 av genomsynligt, böjbart plastmaterial. När infusions- aggregatat skall användas bryts brytstiftet 3 av utifrån med hjälp av den böjliga röranslutningen och kommer den avbrutna delen av brytstiftet att verka som en flödesindikator genom sin utformning med fenor i flödesriktningen. Röranslutningens ll i figur 3 sett vänstra ände skall vara fastsatt vid infusionspå- sen 1 och dess högra ände skall vara ansluten till infusions- slangen 2. Denna typ av brytstift är i och för sig känd.Figure 3 schematically shows the breaker pin 3 in its pipe connection 11 of transparent, bendable plastic material. When infusion sets are to be used, the breaker pin 3 is broken off from the outside by means of the flexible pipe connection and the interrupted part of the breaker pin will act as a flow indicator due to its design with fins in the flow direction. The left end of the pipe connection 11 in Figure 3 must be attached to the infusion bag 1 and its right end must be connected to the infusion hose 2. This type of breaker pin is known per se.

Figur 2 visar hur infusionsaggregatet enligt uppfinningen kan användas utan att påsen 1 på ett osäkert sätt skall place- ras i nivå över den skadade. Som framgår av figuren är in- fusionspåsen 1 placerad under den skadade, vilken sålunda genom sin egen tyngd åstadkommer infusionsvätskans matningstryck. Det är även möjligt att låta den skadade själv krama påsen med sina händer, i det fall den skadade är i stånd därtill. _ Inom ramen för uppfinningen kan som alternativ infusions- nålen olösligt vara fastsatt vid infusionsslangen och med en skyddskåpa 12 omgivande nålen, när aggregatet ej används.Figure 2 shows how the infusion set according to the invention can be used without the bag 1 being placed in a level above the injured person in an unsafe manner. As can be seen from the figure, the infusion bag 1 is placed under the injured person, who thus by his own weight produces the supply pressure of the infusion liquid. It is also possible to let the injured person hug the bag with their hands, in case the injured person is able to do so. Within the scope of the invention, as an alternative, the infusion needle may be insoluble attached to the infusion tube and with a protective cover 12 surrounding the needle, when the unit is not in use.

Härigenom föreligger ett komplett infusionsaggregat.This provides a complete infusion set.

Av ovanstående redogörelse framgår, att infusionsaggrega- tet enligt uppfinningen kan hanteras och användas vid primärt omhändertagande av skadade exempelvis vid katrastrofer, strid "och andra större sjukvårdsinsatser före primärkirurgisk nivå och fungera, utan att behöva hängas upp i droppställning och oavsett dess läge i förhållande till den skadade. Infusions- aggregatet enligt uppfinningen kan även användas av den som har utbildning i infusionsgivning men ej har särskild utbildning på aggregatet. Detta uppvisar även en minimal förpackninge- fy) 467 951 volym.From the above description it appears that the infusion set according to the invention can be handled and used in primary care of the injured, for example in disasters, battles and other major medical operations before the primary surgical level and function, without having to be suspended in a drip position and regardless of its position in relation to The infusion unit according to the invention can also be used by those who have training in infusion administration but do not have special training on the unit.This also has a minimal packaging volume (467,951).
