Definitions

  • the present invention relates to a blood sampling sleeve intended for coaction with a sampling tube in which a subpressure prevails and which is sealed in an airtight and liquid-tight fashion by a sealing device which is capable of being penetrated or pierced by a needle.
  • the sampling sleeve is a one-piece structure intended for one-time-use only, i.e. a so-called disposable sleeve.
  • the sleeve is also friendly to the patient, risk-free to the user and can be manipulated quickly and easily.
  • Samples are generally taken effectively by collecting blood in separate, evacuated vacuum sampling tubes which are sealed against the ingress of air and liquid by means of an appropriate sealing device, such as a rubber stopper.
  • the vacuum sampling tube is used together with a cylindrical sampling sleeve, which is open at one end thereof and provided with a throughpassing, double- pointed needle at the other end thereof.
  • the outer needle point is inserted into a patient's vein and the vacuum sampling tube then pushed into the cyl ⁇ indrical sample sleeve, so that the inner needle point will penetrate or pierce the rubber stopper fitted to the tube.
  • the subpressure prevailing in the sampling tube causes blood to flow through the open passage of the hollow needle and into the tube.
  • the subpressure in the sampling tube may also be generated by fitting a sealing plunger to the other end of the tube and by drawing the plunger out towards the opposite end of the tube, when taking a sample.
  • the sleeve is provided with a two-directional needle, wherein the inner needle is protected against contamina ⁇ tion by a displaceable seal provided at the opposite end of the sleeve, this seal accompanying the rubber stopper when moving the sampling tube axially in the sleeve.
  • the outer part of the needle is protected against con- tamination by a removeable protective cap, which is removed from the needle prior to inserting the needle into the patient's vein.
  • EP-A-0026679 A similar disposable instrument intended for veterinary use is described and illustrated in EP-A-0026679. This instrument is delivered as a complete sampling instru ⁇ ment with the needle and vacuum tube mutually assembled.
  • US-A-4,326,541 and SE-B-425943 describe different exam- pies of how valves are formed in known sampling instruments.
  • the valve taught by US-A-4,326,541 func- tions to close the connection or passageway between the outer and the inner needle when the valve is in its normal, closed position, and opens the passageway from the patient to the sampling tube in response to exter- nal, manual activation.
  • SE-B-425943 teaches an automa ⁇ tic non-return valve, which is disposed between the outer and the inner needle, and a resilient and self- sealing protective sleeve which surrounds the inner needle.
  • the protective sleeve is pierced by the needle when the sampling tube is pushed into the sleeve, and springs back to its original position when the sampling tube is removed for replacement with a fresh tube, so as to stop the flow of blood through the needle.
  • the instrument is also provided with indicator means which indicates the successful puncturing of a vein, when blood flows into the instrument.
  • sampling instruments are encumbered with a number of drawbacks and none of these known instruments fulfils the particular demands that can be placed on instruments of this kind.
  • the double-pointed needle cannot be handled easily by the personnel concerned, who are more accustomed to handling single-pointed needles in other contexts. The risk of injury when changing needles is high, particularly since the inner needle may have been contaminated by a previ ⁇ ous sample.
  • Blood sampling often requires more than one sampling ⁇ tube -to be filled, which involves an exchange of sam ⁇ pling tubes when only one vein puncture is made in the patient concerned.
  • a tube change unavoidably results in the spillage of blood, unless protective measures are taken.
  • the inner needle is often surrounded by an elastic casing which is pierced by the needle together with the rubber stopper fitted to the sampling tube, as taught by SE-B-425943.
  • SE-B-425943 the blood spillage is collect ⁇ ed in the elastic casing and is also deposited on the enclosed needle point.
  • An object of the present invention is to solve the aforesaid problems by providing a disposable sampling sleeve which is friendly to the patient and which can be handled safely and easily by the user.
  • the inventive sampling sleeve is comprised of one or a few simple components, all of which can be produced from readily machined materials of low kilo price.
  • a sampling sleeve of the kind described in the introduction is characterized in that it includes an inner needle which is intended to pierce the sampling-tube sealing device, and an outer, conical, standardized connector intended for connection to a standard vein-puncturing needle.
  • the connector orifice is connected with the needle orifice by an internal channel having arranged therein an internal valve which is closed when in an inactivated position and which is intended to be opened automatically by the tube sealing device when said device is pierced by the needle.
  • the external, standardized connector is formed inte ⁇ grally with the sampling sleeve and enables the use of needles selected from a conventional assortment of needles for sampling purposes. Since the cost of such needles only constitutes a fraction of the cost of the double-pointed needles, this solution affords a considerable reduction in the sampling cost for each patient treated. The use of the simpler form of needles also results in a considerable simplification and there ⁇ with in more rapid handling of the sampling instrument, which also contributes towards a reduction in cost.
  • the same insertion and standard needle as that used to take the sample can be used in said subsequent treatment, thereby relieving the patient of painful, repeated puncturing of the vein and also providing for quicker and more effective handling of the treatment.
  • the possibility of using a standard needle assortment also enables needles of different dimensions to be used with different patients.
  • the simple construction of the sampling sleeve from one or a few components produced from simple and inexpensive materials renders the sleeve viable for one-time-use only.
  • the structural design of the sleeve also enables simple valve means to be used, and in accordance with a preferred embodiment, the sleeve also includes an auto ⁇ matic non-return or check valve which prevents blood from flowing back from the sampling tube.
  • the simple sleeve construction also enables the provision of a simple blood indicator for indicating when a vein has successfully been punctured.

  • the open end of a sampling tube 12 is sealed by an elastic stopper 14, for instance a rubber stopper, in an airtight and liquid- tight fashion.
  • the stopper is formed so that it can be pierced by a needle and so that the hole formed by the needle will reseal automatically as the needle is with ⁇ drawn from the stopper.
  • the sampling tube 12 is evacu ⁇ ated of air, so as to generate an internal subpressure.
  • the disposable sleeve 10 is preferably a one-piece structure manufactured from a plastic material, and is open at one end thereof so as to enable the sampling tube 12 to be pushed into the cylindrical sleeve 10.
  • the other end of the sleeve 10 is provided with an end- part 15 which is provided with a centrally positioned, inwardly directed needle 16 and a preferably eccentri ⁇ cally positioned outwardly extending connector 22.
  • An angled channel 20 extends from one orifice in the con ⁇ nector 22, along the end-part 15 and through the inter- nal needle 16.
  • the connector 22 is a standardized fitting for standard injection needles and consists, for instance, of a Luer, Record or like standard fitting to which needles from a standard needle assortment can be connected.
  • the needle When taking a sample from the vein of a patient, the needle is preferably inserted in a direction which is as paral ⁇ lel as possible with the direction of the vein, since otherwise there is a risk of also piercing the back wall of the vein, particularly in the case of fine veins.
  • An eccentrically positioned connector 22 with a so-called Loeb-fitting enables the standard needle connected to the connector 22 to be inserted at a better angle than otherwise, therewith facilitating puncturing of the vein.
  • the connector 22 may also be placed centrally on the end-part 15, although the eccentric positioning of the connector is preferred, among other things because it facilitates puncturing of a vein, and because the lateral position of the connector provides more space for accommodating both a valve function and an indicat- ing function, as described in more detail herebelow.
  • the sampling sleeve illustrated in Figures 1-2 solves the problem of blood spillage when changing sampling tubes with one and the same needle inserted in the patient's vein, in that the inner needle 16 is formed inte-grally with a flow valve 26.
  • This inner flow valve 26 is formed in the needle between the obliquely cut needle point 18 and the end-part 15 of the sleeve, wherein in its non-activated state, the flow valve functions to close the passage through the angled chan ⁇ nel 20 between the connector 22 and the point of the needle.
  • the needle is made from a resilient material, and the flow valve is formed by biasing the walls into abutment with one another in one section of the needle, see Figures 2a-b, so as to close the channel and prevent blood from flowing therethrough.
  • the sampling tube with its rubber stopper 14, is pushed into the sleeve 10
  • the needle point 18 pierces and perforates the stopper.
  • the stopper reaches the valve section 26 of the needle, the elastic material from which the stopper is made presses against the end-parts 30 of the valve so as to open the inner passageway 20, as shown in Figure 2b, whereupon blood will be drawn into the sam ⁇ pling tube as a result of the subpressure prevailing therein.
  • the valve section 26 may also take other forms in its non-activated state, for instance the forms illustrated in Figures 3a and 3b.
  • the valve section will return to its original non-activated form, therewith immediately shutting-off the blood flow.
  • FIGs 4 and 5 illustrate two further valve means, both of which are formed integrally with the sampling sleeve 10.
  • the valve 26 has the form of a tongue 24 which forms an integral part of the end-part 15 above the channel 20, said tongue lying against the angled edge 25 of the channel such as to stop the flow of blood when the valve is in its non- activated state.
  • the tongue 24 is forced up by the stopper, therewith opening the valve and allowing blood to flow through the channel.
  • the needle is twisted about itself, so that the inner channel 20 is closed when the needle is in a non-activated state. As the twisted needle penetrates the rubber stopper, the needle is untwisted and therewith opens the channel 20.
  • FIGS 6a and b illustrate a further alternative em- bodiment of the flow valve 26.
  • two dia ⁇ metrically positioned wings 32 are formed integrally on the outside of the needle 16.
  • the channel 20 is provid ⁇ ed with two mutually opposing lips 34 which are formed integrally with the channel walls and which function to close the channel 20 when the wings 32 are in their non- activated, mutual positions, i.e. extend horizontally.
  • the wings 32 are forced upwards so as to mutual- ly separate the inner lips 34 and therewith open the channel 20.
  • the wings return to their neutral positions, and thus also the lips 34, therewith closing the channel.
  • the valve 26 is comprised of two separate parts, one of which is a centric pin 36 which is formed in ⁇ tegrally with the sleeve and the outer part of which widens into a spherical head 38.
  • the neck 40 of the pin 36 is provided with a number of symmetrically positioned grooves 42.
  • Firmly welded to the periphery of the inner end-part 15 of the sleeve 10 is a relatively rigid, but slightly elastic, plastic diaphragm 44.
  • the diaphragm 44 is curved around the head 38 and therewith forms an abutment surface 46 which, in a neutral position, sealingly abuts the spherical head 38 of the valve so as to close the blood passageway through the sampling sleeve.
  • the diaphragm continues from the abutment surface 46 to form a widened cavity 48 and thereafter tapers to form a pointed needle 16.
  • the bottom of the sleeve 10 is also provided with internal grooves 50, the function of which will be described herebelow.
  • Figure 7b illustrates how the valve 26 is opened when the sampling tube, together with the rubber stopper, is pushed into the sleeve.
  • the diaphragm 44 is pushed up against the bottom of the sleeve and in its furthest inserted position lies against the grooves 50 on said bottom surface.
  • the grooves 50 on the bottom surface and the grooves 42 on the pin ensure that blood will flow uniformly through the passageway.
  • the sampling sleeve illustrated in Figure 7 may be provided with a non-return valve, for instance in the form of a flexible, funnel-shaped flange mounted on the underside of the spherical head.
  • the downwardly hanging flange is forced to one side by the blood that flows into the cavity 48 and from there into the sampling tube. If, on the other hand, there occurs a drop in pressure in the vein or an increase in pres ⁇ sure in the sampling tube, the soft and pliant flange is forced out into sealing contact with the inner walls of the cavity, therewith preventing backward flow of the blood.
  • FIGs 8a-8 ⁇ illustrate a preferred embodiment having a valve means 26 which, in this case, also functions as an automatic non-return valve.
  • the valve means operates automatically in the event of a drop in pressure in the vein or in the event of a pressure increase in the sampling tube.
