Snappare, sjukvArdsinstrument ulir blodprovstagning. Faster, medical instruments for blood sampling.

FOreliggande uppfinning avser en snappare, vilken är avsedd for tagning av blodprov. The present invention relates to a snapper which is intended for taking blood samples.

Uppfinningen kannetecknas i huvudsak dray, att snapparen bestar av en i en -ytterhylsa forskjutbar, fjaderpaverkad med ayseende pa sin. slaglangd installbar och med tillhjalp av en sparranordning utl5sbar slaghylsa, som är anordnad att paverka en i en hylsa forskjutbar i en fjaderpaverkad spanntang fastbar kniv, vilken hylsa är insattbar i ett vid ytterhylsans ena dude lostagbart anordnat stad. The invention is essentially characterized in that the snapper consists of a displaceable, spring-shaped displaceable in an outer sleeve with a view of its own. longitudinally installable and with the aid of a spar device releasable percussion sleeve, which is arranged to actuate a knife slidable in a sleeve displaceable in a spring-actuated collet, which sleeve is insertable in a city removably arranged at one of the outer sleeves.

Detta och Ovriga for uppfinningen utmarkande kannetecken komma att narmare forklaras i samband med den efterfOljande beskrivningen av en pa bifogade ritning askadliggjord och enligt uppfinningen utford snap-pare for blodprovstagning. This and other features which can be distinguished from the invention will be explained in more detail in connection with the following description of a drawing which is enclosed in the accompanying drawing and, according to the invention, challenges snappers for blood sampling.

Fig. 1 askadliggiir i langdsektion en utföringsform av den enligt uppfinningen foreslagna snapparen, medan fig. 2 och 3 visa detaljer till denna. Fig. 1 shows in longitudinal section an embodiment of the snapper proposed according to the invention, while Figs. 2 and 3 show details thereof.

PS ritningen betecknar 1 ett lOstagbart stOd fOr en i en hylsa 20 Mrskjutbart anordnad kniv 2. Med 3 betecknas en ph hylsans 20 ytterande anbringbar lasring. Med 4 betecknas en spanntang, som Sr avsedd att gripa om kniven 2. Med 5 betecknas en slaghylsa och med 6 en ytterhylsa, vid vars ena ande stodet 1 Sr anordnat att insattas. Med 7 betecknas en slagfjader, som Sr inspand i hylsan 6 mellan slaghylsan 5 och en i hylsans 6 andra andparti insattbar styrning 9. Med 8 betecknas en likaledes i form av en skruvfjader utford spanntangsfjader. Med 10 betecknas en djupinstallningshylsa, medelst vilken slagdjupet kan installas. Med 11 betecknas en andmutter och med 12 en snannknapp, medelst vilken slagfjadern 7 kan spannas. Vid spannknappen 12 Sr med sin ena dude fast en dragstang 13, som med sin andra ande är fast vid spanntangen 4. Med 14 betecknas en vinkelratt mot hylsan 6 anordnad sparrhylsa, i vilken Sr fOrskjutbart anordnad en av en sparrfjader 15 paverkbar sparrhake 17, vilken Sr styrd i en i hylsan 14 inskruvbar mutter 16. Med 18 betecknas en svangbar tryckknapp, vilken Sr lagrad i ett p5 hylsan 6 fast stod 19, vil- ken tryckknapp Sr forsedd med ett utsprang, som skjuter in i en Oppning i sparrhaken 17, vilken Sr anordnad att ingripa i pa slaghylsans utsida anordnade tander. PS the drawing denotes 1 a detachable support for a knife 2 slidably arranged in a sleeve 20. Denoted by 3 is the outer attachable lasing ring of a ph sleeve 20. Denoted by 4 is a collet, which Sr is intended to grip the knife 2. Denoted by 5 is a percussion sleeve and by 6 an outer sleeve, at one end of which the stand 1 Sr is arranged to be inserted. Denoted by 7 is a percussion spring which Sr clamped in the sleeve 6 between the percussion sleeve 5 and a guide 9 insertable in the second end portion of the sleeve 6. Denoted by 8 is also a collet spring which is also challenged in the form of a helical spring. 10 denotes a deep installation sleeve, by means of which the stroke depth can be installed. By 11 is denoted a duck nut and by 12 a knob, by means of which the strut spring 7 can be tensioned. At the clamping button 12 Sr is fastened with its one dude a drawbar 13, which with its other spirit is fixed to the clamping rod 4. Denoted by 14 is a ratchet sleeve arranged at an angle to the sleeve 6, in which Sr is displaceably arranged a ratchet hook 17 which can be actuated by a ratchet spring 15, Sr controlled in a nut 16 which can be screwed into the sleeve 14. Denoted by 18 is a pivotable pushbutton, which Sr mounted in a p5 sleeve 6 was fixed 19, which The push button Sr is provided with a projection, which projects into an opening in the ratchet 17, which Sr is arranged to engage in teeth arranged on the outside of the percussion sleeve.

Den enligt uppfinningen foreslagna snapparen verkar p5 foljande satt: Spannknappen 12 tryckes in, kniven 2 och stOdet 1 tryckes in i ytterhylsan 6, varvid spanntangen 4 griper om kniven 2, varefter spannknappen 12 slappes. Harefter nedtryckes tryckknappen 18, varvid slagdjupet installes medelst djupinstallningshylsan 10. Harefter spannes slagfjadern 7 genom att man drager i spannknappen 12, varvid spanntangen 4 Liven far ett fastare grepp om kniven 2. Slagfjadern 7 utloses genom att tryckknappen 18 nedtryckes, varvid sparrhaken 17 bringas ur ingrepp med slaghylsans 5 tandning. Vid byte av kniv 2 och stod 1 intryckes spannknappen 12, varefter kniven och stOdet latt kunna borttagas. Genom att kniven 2 och stOdet 1 p5 ett enkelt satt kunna utbytas mot steriliserade detaljer for varje patient erbjuder den enligt uppfinningen foreslagna snapparen avsevarda fordelar gentemot de nu befintliga mekaniska snapparna, vid vilka smitta latt kan overforas frail en patient till en annan. The snapper proposed according to the invention operates in the following manner: The clamping button 12 is pressed in, the knife 2 and the stud 1 are pressed into the outer sleeve 6, the clamping tongs 4 gripping the knife 2, after which the clamping button 12 is released. Then the pushbutton 18 is depressed, the impact depth being installed by means of the deep installation sleeve 10. Then the impact spring 7 is tensioned by pulling the clamping button 12, whereby the clamping pliers 4 Liven have a firmer grip on the knife 2. The impact spring 7 is released by depressing the pushbutton 18. engagement with the impact sleeve 5 toothing. When changing knife 2 and stand 1, press the clamping button 12, after which the knife and the stand can be easily removed. By being able to easily exchange the knife 2 and the support 1 p5 for sterilized details for each patient, the snapper proposed according to the invention offers considerable advantages over the existing mechanical snappers, in which infection can be easily transferred from one patient to another.

Uppfinningen Sr givetvis icke begransad till den nu beskri-vna och visade utforingsformen utan kan denna varieras pa flera satt inom ramen for uppfinningen. The invention is of course not limited to the embodiment now described and shown, but this can be varied in several ways within the scope of the invention.
