Standard over-the-needle insertion with Midline Performance

Frequently Asked Questions


Similar to other catheters for similar length of stay that were found to be suitable, the M29 is also good for antibiotic, for longer stays, and orthopedic cases.
Antibiotic used in orthopedic usually requires 5-10 days of treatment, hence the Bullpup will be very helpful in these cases.
Because their tips are positioned in larger veins, Midlines may be suitable for some hypertonic medications and solutions (<600mEq/L) 5<pH<9

The insertion procedure is similar to a standard IV, hence anyone who inserts a standard IV can handle the M29. It does not require the specialization of an expert in midline procedure.

Yes, the tip of the needle can be seen and followed.

Orthopedics, OPAT, Geriatrics, Geriatrics, ICU and ICU discharge to other departments after removal of central venues catheters, usually removed when discharged from ICU

It’s actually both, it can replace Some midline applications and the standard Peripheral that require multiple restarts, deeper vein access and better stability.

It is over-the-needle catheter or Direct puncture. It cannot be used with the Seldinger technique.

As Bullpup M29 is a new product in the market, we are still working on providing more studies.

Theoretically, blood can be withdrawn from the catheter, but usually it is not advised to withdraw blood from any catheter as it increases the chance of complications. However, if you do, you will have to follow strict heparin flash procedure.

All catheters are susceptible to kinks. Ours is stable and has similar kinking characteristics as a standard PU cannula. These are much more kink resistance than your standard Midline as the insertion done over a needle that prevent kinking during insertion.

The position of the tip is the indicator for highly corrosive material, not the catheter itself. PICC is essentially Centrally located and not peripheral as Midlines. Hence, not all medication suited for PICC are to be used with a Midline.

It is recommended to insert in the upper arm, because upper arm insertion have longer dwelling time. But it can also be used in the lower arm. In any case, it is important to make sure the tip is either above or below the elbow

It works like a standard peripheral and the needle is part of the device but the intelligent design uses only the forward portion of the device the same as a short term cannula.

The M29 is a midline catheter and as such it is approved for up to 29 days of dwell time.
The length of the catheter (8.5cm – 10cm) gives it stability and increases the distance between the insertion point to the location the medicine is released, thus lowering the effect of the medicine on the insertion point.
The longer the catheter, the larger the vessel its tip resides in and the Hemo-dilution is improved and more stable, moving less in the vein with improved flexibility. In addition, the point of release of the medication is further away from the entry point, allowing for longer dwell times over a short cannula.
The M29 thus decreases the number of insertions in longer than average length of stays in hospitals.


8.5cm – 10cm

There are fixation holes.
Issues to patients’ skin are very similar to other brands.

Any patient requiring or assumed to require more than 3 days of IV access
Any patient Hospitalized frequently
Any patient with difficult vein access
Especially patients over 70 would benefit from preserving the veins and reducing re-start number

Yes, a single needle free extension line to the hub is the recommended procedure

It is suitable for use with power injectors up to 325psi.

Most commercial Starters kit for IV cannula will work with The M29.

It is a port designed for bolus injections and quick access to the vein. It is also possible to have a non-ported version of the M29.

It is a class 2 device
