3.PREAMBLE TO THE DESCRIPTION
PROVISIONAL

N / A COMPLETE

The following Specification particularly describes the nature of this invention and the manner in which it is to be performed :

4. TEACHING FIELD

The present invention relates to medical sciences and more particularly to the field of anaesthesiology where in an adaptor is devised which will convert an ordinary intra venous cannula as a sheathed nerve stimulator needle.

This will be useful to give peripheral nerve blocks using a peripheral nerve locator and an I.V cannula.

5. BACKGROUND

Regional anaesthesia is the technique of giving anaesthesia to a specific region of body for surgery specific to that region. This is especially important when the patient has comorbid condition which warrants the avoidance of general anaesthesia.

There are also surgeries which does not require general anaesthesia but can very well be managed with regional nerve blocks e.g. - Surgery of hand or arm.

Even though specific disposable needles are available in the market for the purpose  availability and affordability limits its usage and also same reasons encourage reuse after sterilising. This adaptor is a disposable & economical alternative to convert the commonly available I.V cannula to a nerve stimulator needle.

6.SUMMARY

The IVCON ADAPTOR is made of poly tetra fluro ethelene and has a stainless steel needle. It is designed in such a way to firmly fit into the injection port of I.V cannula piercing the rubber sleeve.

This achieves a contact between the stylet of I.V cannula and the adaptor.

Now the wire arising from the needle can be connected to a peripheral nerve locator and preceded for locating the nerve.

After locating the nerve the local anaesthetic can be injected through the “black-flash” hub of the stylet.

Once the procedure is over the stylet and adaptor can be removed and the cannula left in place for continuous blockade of the nerve if required.

All the three pieces – adaptor  I.V cannula and stylet can be disposed after the surgery.
7. BRIEF DESCRIPTION OF DRAWINGS:

Fig: No.1 is the schematic representation of IVCON ADAPTOR.

8.DETAILS DESCRIPTION OF DRAWINGS:

Fig.No.1 shows the stainless steel needle (1)  stem (2)  fins for grip (3)  body (4)  and wire (5).

The IVCON ADAPTOR has a space between the stem (2) and the body (4). While connecting the IVCON ADAPTOR to injection port of i.v. cannula the needle (1) and stem (2) fixes inside the port and the body stays outside the port. The fins for grip (3) are provided to grip the adaptor while removing. The wire (5) has to be attached to the peripheral nerve locator terminal.

9.I claim

1. The IVCON ADAPTOR can convert an I.V. cannula to a nerve stimulator needle for the purpose of giving regional anaesthesia.

2. This is the first time such simple  low cost disposable adaptor is made available for use in regional anaesthesia.

3. The IVCON ADAPTOR  as herein described and with reference to accompanying drawing.
