Abstract
Abstract A tray on which to transport and from which to dispense hypodermic syringes or other instruments having needles normally covered by sheaths is intended for use by health care workers and those who are exposed to the dangers of accidental puncture wounds from contaminated needles. The tray is so constructed as to secure the instruments with their needles in their sheaths during transportation, while enabling removal and resheathing of an instrument using only one hand. This result is achieved by providing for each instrument a barrel containing a device for gripping the sheath of the instrument and for releasing such grip only upon manual tilting of the barrel.
Description
1~78729 Device for su_portinq and dis~ensin~_an instrument ________ __ _ ________ ____ ___________ Ba~roun_ t_ _he Inv__tion The present invention relates to a device, e.g. a medical tray, that has been especially designed for health care workers who, in the nature of their work, are required to carry hypodermic syringes or other instruments having needles to patients and administer injections or extract blood. This procedure is presently typically conducted by loading a syringe with serum at a location that is often remote from the patient. A syringe is taken from its wrapping and the sheath is withdrawn from the needle of the syringe and manually replaced after the serum has been drawn into the syringe. The syringe is then carried to the patient and again the sheath is withdrawn and the needle exposed for injection. Following the injection, the needle is considered to be contaminated and potentially dangerous. A similar procedure is conducted for a patient from whom blood is to be extracted, with manual unsheathing and sheating of the needle of the instrument.
A common accident that can cause infection is the result of manually resheathing the needle. Holding the instrument in one hand and inserting it into the sheath in the other, introduces the possibility of a self-inflicted ~, 1~78729 puncture wound. Alternatively, returning to the disposal station without first resheathing the needle increases the risk of accidental contact with the exposed needle. Most modern syringes and like instruments are disposable and are discarded after one use.
Summary of the Invention ______ _ _______________ In one aspect, the invention consists of a device for supporting and dispensing an instrument having a needle portion normally covered by a protective sheath, said device comprising (a) holding means for receiving a said sheath, (b) gripping means for gripping the sheath in the holding means, and (c) means for mounting the holding means for movement between two positions in a first of which the instrument rests in a first orientation for transportation, and in a second of which the instrument extends in a second orientation for convenient removal from and subsequent reinsertion into the sheath by a user while the sheath is retained in the holding means.
Preferably, the mounting means mounts the holding means for movement to a third position in which the gripping means is open to release the sheath from the holding means.
In another aspect, the invention consists of a device for supporting and dispensing an instrument having a needle portion normally covered by a protective sheath, said device comprising (a) holding means for receiving a said sheath, (b) gripping means for gripping the sheath in the holding means, and (c) means for mounting the holding means for movement between a gripping position in which the gripping means is closed to grip the sheath in the holding means and a release position in which the gripping means is open to release the sheath from the holding means.
Preferably, the device includes a tray portion having walls defining a shielding recess in which the instrument can rest.
1'~787Z9 The preferred form of the invention provides a tray having the capacity to contain two syringes lying side-by-side. Each syringe is secured in the tray by means of holding means in the form of a barrel containing gripping means acting against the sheath, this gripping of the sheath being firmer than the frictional grip of the sheath against the syringe. This permits each syringe to be withdrawn from its sheath while the latter remains secured in the barrel in the tray.
Each barrel can be pivotable about a horizontal axis between two extreme positions, while being counter-balanced to rest in an almost upright, intermediate position when the syringe is withdrawn from the sheath.
This arrangement permits (a) the syringe, by its weight, to normally rest horizontally in the tray (the "~irst extreme position" of the barrel and the "first" or "transportation orientation" of the syringe), (b) the syringe to be tilted manually and withdrawn from the sheath at an angle, (c) the empty sheath to pivot to a more upright position (the "intermediate position" of the barrel and the "second orientation" of the syringe) to be in position for easy reinsertion of the syringe into the sheath, and (d) release of the sheath from the barrel by manual movement of the barrel to its "second extreme position" with consequent release of the gripping means.
Brief De_cription_of the-nrawin~s Figure 1 shows a partly cut away view of a tray according to an embodiment of the invention containing two syringes, the closer of the two syringes being shown in position for transportation;
12787Z~t Figure 2 shows a sectional side view of the left hand end of Figure 1 on an enlarged scale; and Figures 3 and 4 are the same as Figure 2 with the parts in different positions.
D_t_iled D____l~t1on__f _he_Preferr_d_E_b_di___ts A device 10 forms part of a tray 11 designed to support two aligned holding means in the form of cylindrical barrels 12 which pivot about a common fulcrum 14. Within each barrel 12 and occupying the space between the fulcrum 14 and a closed end 16 of the barrel there is a balance weight 18. On the underside of each barrel 12 there is a spring 20 which extends from the closed end 16 to a gripping jaw 22 that penetrates the barrel 12 through a slot 24 slightly inwardly spaced from a mouth 26 of the barrel. This jaw 22 cooperates with a roughened surface 28 on the opposite inside face of the barrel to grip a protective sheath 30 of a syringe 32. The jaws are opened within the barrel by moving the barrel to a 90 angle relative to the device 10 (Figure 4), in which position a transverse bar 34 secured to the spring 20 adjacent the jaw 22 engages surfaces 36 of the device 10 to overcome the action of the spring. In this position the syringe sheath 30 can be inserted freely into the barrel or withdrawn therefrom.
The nearer of the two syringes 32 in Figure 1 is shown with its sheath engaged in the barrel and secured therein by the jaw of the barrel. The weight of this syringe exceeds that of the weight 18, causing the syringe to lie flat in the tray on a rest 38, i.e. the so-called "first extreme position" of the barrel and the "first" or "transportation orientation" of the syringe.
When a syringe 32 is to be withdrawn from the tray for use, it can first be raised from its resting position (arrow A) with its sheath 30 remaining engaged in the barrel 12 (Figure 2). The syringe 32 can then be 3,q~9 withdrawn from its sheath 30 (arrow B), the grip of the jaw 22 within the barrel 12 on the sheath 30 being greater than the frictional engagement of the sheath 30 to the syringe 32.
Only the sheath 30 now remains in the barrel 12. The weight 18 exceeds the weight of the sheath 30 and causes the barrel 12 to pivot to a relatively upright, so-called intermediate position (Figure 3). This intermediate position is convenient for reinsertion of the needle of the syringe into the sheath after use, i.e. the so-called second orientation of the syringe.
Following such reinsertion of the needle, the syringe will again overcome the weight 18 and return to its horizontal orientation in the tray on the rest 38. This rest 38 facilitates the grasping of a syringe when it is to be lifted from the tray.
Either the sheath 30 alone or the sheath and syringe 32 together can be released from the tray by moving the barrel to its second extreme (vertical) position (Figure 4) by pressure on a finger piece 40 secured to the barrel (arrow C), thus causing the engagement of the bar 34 on the surfaces 36 to open the jaw 22 (arrow D).
It is to be noted that the invention includes a device 10 that is similar to the left hand end of the assembly shown in Figure 1 without the tray portion 11, such a device being adapted for use with a separate tray or with some other surface on which the syringe or other instrument can rest for transportation purposes.
A common accident that can cause infection is the result of manually resheathing the needle. Holding the instrument in one hand and inserting it into the sheath in the other, introduces the possibility of a self-inflicted ~, 1~78729 puncture wound. Alternatively, returning to the disposal station without first resheathing the needle increases the risk of accidental contact with the exposed needle. Most modern syringes and like instruments are disposable and are discarded after one use.
