An instrument (1) for use in measuring blood flow in the femoral head after a femoral neck fracture comprises a sleeve (2) and a rod (3) which is displaceably mounted in the sleeve. The sleeve (2) is configured for insertion into a bore (4) in the femoral neck (5) and femoral head (6) and provided with at least one aperture (8) at a front portion (2a) thereof. The aperture (8) in the front portion (2a) of the sleeve (2) is intended for location in the femoral head (6) distally of the fracture (7) after the sleeve has been inserted into said bore (4). The rod (3) is configured for closing the aperture (8) in the sleeve (2) during insertion of the sleeve into the bore (4) in the femoral neck (5) and femoral head (6) and for exposing said aperture after said insertion. Thereby, blood leaking into the bore (4) at the front portion (2a) of the sleeve (2) can be collected by the sleeve through the aperture (8) therein for subsequent measuring of the volume of the collected blood.

A blood collection assembly includes a hub with a distal end, a proximal end, a hub outer surface and an internal opening extending therethrough. The assembly also includes a holder housing defining a receiving chamber and having a rearward end adapted to receive a sample collection tube within the chamber and a forward end including a receiving port extending into the chamber, where the receiving port receives a portion of the proximal end of the hub therein. An internal opening of the hub accommodates a puncturing element at the proximal end thereof for providing passage of a fluid therethrough, and the puncturing element contacts the sample collection tube. The hub and the holder housing include an interengaging structure extending substantially perimetrically therearound for axially locking the hub with the holder housing.

A protective cover is attached to a measurement device. The measurement device is provided with an insertion aperture for insertion of a test strip onto which a liquid sample is spotted. The protective cover is attached to the measurement device so as to cover a region including surroundings of the insertion aperture. The protective cover is provided with an opening portion into which the test strip is insertable. The opening portion and the insertion aperture are relatively positioned such that, in a state in which the test strip is inserted through the opening portion and inserted into the insertion aperture, an upper face and lower face of the test strip both abut against the protective cover.

This disclosure generally relates to medical devices that include a sensor transmitter assembly that includes a sensor assembly including a sensor module where a first sensor including a first sensor head having at least one first sensor contact pad is combined with a second sensor including a second sensor head having at least one second sensor contact pad. The sensor transmitter assembly also includes a transmitter assembly positioned on a top of the sensor assembly to form a single unit, the transmitter assembly having at least one transmitter contact disposed on a base of the transmitter assembly, where the first sensor contact pad(s) and the second sensor form a connection path with the transmitter contact(s).

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

A biopsy needle unit includes a biopsy needle and an elastically deformable safety tube for partially covering the biopsy needle inserted to a lumen extending in a longitudinal direction. A marker is arranged on the biopsy needle at a position protruding from an end portion of the safety tube on an opposite side of a needle tip of the puncture needle when the needle tip portion is accommodated in the lumen. The safety tube has portions in which the lumen is curved at least partially with respect to the longitudinal direction so that the safety tube is elastically deformed due to contact between an inner circumferential face of the lumen and an outer circumferential face of the biopsy needle when the biopsy needle is inserted to the lumen to cause frictional resistance between the inner circumferential face of the lumen and the outer circumferential face of the biopsy needle.

A needle assembly includes a housing having proximal and distal ends, an IV cannula projecting distally from the housing, and an IV shield having an engagement. The housing has a shield seat and the IV cannula has a distal tip. The IV shield has a pre-use position where the IV shield covers the distal tip of the IV cannula and the engagement is disengaged from the shield seat, and a use position where the engagement is engaged with the shield seat and the IV shield is adapted to move between a non-shielded position, in which the distal tip is exposed, and a shielded position, in which the distal tip is shielded by the IV shield.

A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.

A novel blood collection device is described to secure a needle in place in a placenta or umbilical cord to prevent needle stick before, during, and after cord blood collection procedure.

The present disclosure is a blood collection assembly that has a needle assembly fixedly coupled to a finger-activated actuator and tubing and the needle assembly has a needle. Further, the blood collection assembly has a hub that houses the needle assembly and the hub has a channel in a top surface of the hub. Additionally, the channel slidably engages the finger-activated actuator such that when the finger-activated actuator is moved from a distal end of the hub to a proximal end of the hub the needle retracts within the hub.
