Definitions
- the present invention relates to a hypodermic syringe, the use of which is made impossible after a first use.
- the syringe according to the invention has a device for clipping the needle preventing it from being reused on another syringe.
- the piston is provided with a drive device on translation l has each qcarlgmgnt in the direction A as r epi deentd Fig.1.
- the rear part of the syringe is equipped with a mud tab device whose function is to immobilize the piston.
- device is made integral with the syringe body. When using the syringe the effect of this device is canceled by a ring holding the locking tabs apart.
- the needle is made removable by a clipping device.
- the needle can be made removable by overmolding.
- the devices for driving and blocking the piston are produced in the form of racks molded on the body of the piston.
- the gear devices can; be produced in the form of; metal parts, for example beryllium bronzo, overmolded on the spacer ring and on the locking device.
- Figure 1 shows in section the disposable syringe.
- Figure 2 shows in section a variant of this syringe.
- Figure 3 shows the piston.
- Figure 4 shows the locking device
- Figure 5 shows the spacer ring.
- the syringe shown in Figure 1 has a syringe body.
- the needle is made non-removable by gluing, over-clipping.
- the piston shown in Figure 3 is made of soft plastic
- the body of the piston consists of 2 ribs, the section of which is a cross. 2 branches of this cross have over their entire length l rack made up of teeth with a pitch of the order of 1.5 mm. The of these teeth is such that the gear occurs only in 1 senles two other branches of this cross have 1 rack opposite to the first.
- This blocking device is produced in 2 half parts molded in the form of a cylinder having at one end a shoulder intended to make it integral with the body of the syringe by gluing, heat welding or ultra-sound welding.
- the tongues mounted so that, at rest, the teeth are engaged in the rack of the piston: their section and the mat used for their manufacture allows the tooth to be released by pressure on the tongue.
- a spacer ring marked 4 in FIG. 1 produced in 2 half molded parts has at one end a shoulder introduced into the tongues of the blocking device so as to keep the teeth away from the rack of the piston.
- This shoulder is such that the tongues of the blocking device are released after a stroke of approximately 2.5 mm.
- the seri ngue sel on i nventi on is part i cially i ndicated to combat the spread of S IDA and hepatitis B by the use of contaminated seri ngues.
