A biological fluid separation device that is adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the biological fluid separation device is able to separate a plasma portion from a cellular portion. After separation, the biological fluid separation device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The biological fluid separation device of the present disclosure also provides a closed separation and transfer system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer. The biological fluid separation device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the biological fluid separation device to the blood testing device. The blood testing device is adapted to receive the plasma portion to analyze the blood sample and obtain test results.

A detection device for cannabinoid use including a base unit and a display screen disposed on the base unit. A central processing unit and a tetrahydrocannabinol testing device are disposed within the base unit. A testing slot is disposed on a bottom portion of the base unit, with a back end of the testing slot disposed within the tetrahydrocannabinol testing device. Each of a plurality of testing strips is slidably and removably disposed within the testing slot. A printer has a pair of T-shaped attachment extensions. Each of the pair of attachment extensions and a universal serial bus plug disposed on the printer simultaneously removably and slidably engages each of a pair of attachment slots and a universal serial bus port disposed on the base unit, respectively. The tetrahydrocannabinol testing device is configured to analyze and calculate the presence and amount of tetrahydrocannabinol in a person's bloodstream.

The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood, from subjects, e.g., from the skin and/or from beneath the skin. In one aspect, the present invention is generally directed to devices and methods for receiving or extracting blood from a subject, e.g., from the skin and/or from beneath the skin, using devices containing a fluid transporter (for example, one or more microneedles), and a storage chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In some cases, the device may be self-contained, and in certain instances, the device can be applied to the skin, and activated to receive blood from the subject. The device, or a portion thereof, may then be processed to determine the blood and/or an analyte within the blood, alone or with an external apparatus. For example, blood may be received from the device, and/or the device may contain sensors or agents able to determine the blood and/or an analyte suspected of being contained in the blood. In another aspect, the present invention is generally directed to arrangements of skin insertion objects such as microneedles and methods of forming and arranging skin insertion objects. Other aspects of the present invention are directed at other devices for receiving blood (or other bodily fluids, e.g., interstitial fluid), kits involving such devices, methods of making such devices, methods of using such devices, and the like.

The present invention discloses a push-type safety protection mechanism of a blood collection needle. The push-type safety protection mechanism comprises a sleeve member and a valve core member, wherein the valve core member is provided with three parts, namely a needle seat part, a sleeving part and a stopping part; a plurality of limiting grooves is formed in the stopping part; the sleeve member is provided with two parts, namely a first sleeve part positioned at a front section and a second sleeve part positioned at a rear section; an elastic button higher than the side wall of the first sleeve part is arranged on the side wall of the valve core member; a limiting opening matched with the elastic button is formed in the side wall of the first sleeve part; a limiting sliding cavity for accommodating the elastic button and the valve core member is formed from a position of the first sleeve part from the limiting opening to the inner side of the second sleeve part, and the limiting sliding cavity guides and limits front-back movements of the elastic button and the valve core member; and a plurality of elastic limiting protrusions matched with the limiting grooves is arranged on the inner wall of the tail sliding cavity of the second sleeve part. Through the design of the elastic button, medical staff can operate the blood collection needle with the left hand or the right hand alone during use.

A miniature safety blood lancet for minimizing pain includes a needle body, an activation sleeve, a housing and a spring. The activation sleeve is arranged in the housing. The needle body is arranged in the activation sleeve. The housing, the activation sleeve and the needle body are slidably connected. The activation sleeve is provided with an inner wall. The inner side of the middle of the inner wall is provided with an unlocking arm, and the outer side of the bottom of the inner wall is provided with a buckle. A needle cap is arranged at the front end of the needle body. The unlocking arm of the activation sleeve is snap-fitted with a self-locking protrusion of the needle cap and an inverted buckle of the housing, respectively. The spring is arranged between the bottom of the needle body and the housing.

A disposable lancing device contains: a first casing, a second casing, and a needle holder. The first casing includes a close segment, an open segment, a slideway, two tilted contact faces, a fixing portion, two recesses, and two push fringes. The second casing includes an accommodation chamber, two limitation extensions, and multiple drive protrusions. A forcing face is defined on the second casing opposite to the two limitation extensions, and a through hole is defined on a center of the forcing face. The through hole has a protruded rib. The needle holder includes a collection needle having a syringe needle, and the needle holder further includes a trigger spring, a return spring, and two symmetrical flexible wings. The two symmetrical flexible wings include two driving segments configured to abut against the two symmetrical flexible wings to flexibly retract inward by using the two tilted contact faces.
