A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient.

Apparatus and methods for a single, handheld device that provides for both insertion of a catheter and collection of a fluid. Some embodiments further include a needle that assists in the insertion of the catheter into a blood vessel, and which includes a retraction feature that protects the user from an accidental needle stick when the device is ready for disposal. Still further embodiments include a protective cover that prevents a user from accidentally being stuck by a second needle used for the introduction of the patient's blood into a collection device.

The present disclosure relates to an insertion guide needle for a continuous glucose monitoring system. The insertion guide needle makes an incision in the skin by means of point-contact with the skin during a skin insertion process, and allows expanded incision of the skin continuously thereafter, thereby minimizing pain which may occur during the skin insertion process and thus relieving aversion or tension when the continuous glucose monitoring system is used. During a process of expanded incision of the skin, the insertion guide needle allows expanded incision continuously and gradually in the width direction and thickness direction, thereby reducing skin resistance during the expanded incision process and further reducing pain. In addition, during the expanded incision process, since the entire incision area is formed by an incision, the insertion guide needle is simply inserted along the incision area after a predetermined insertion section, such that almost no pain occurs during the insertion process.

A sample collection container configured to be removably mounted to a blood collection device includes: a housing having a flow channel extending through the housing having an inlet and an outlet and a container body removably connected to the housing. The container body includes an open top, a closed bottom, and an interior wall extending between the top and the bottom defining a collection cavity. When the housing is connected to the container body, the outlet of the flow channel is in fluid communication with the collection cavity. The sample collection container also includes at least one additive dispersing object positioned to be contacted by blood flowing from the blood collection device through the flow channel and/or into the collection cavity. The at least one additive dispersing object includes an additive composition to be mixed with the blood passing along the flow channel and into the collection cavity.

This invention is in the field of medical devices. Specifically, the present invention provides fluidic systems having a plurality of reaction sites surrounded by optical barriers to reduce the amount of optical cross-talk between signals detected from various reaction sites. The invention also provides a method of manufacturing fluidic systems and methods of using the systems.

A flow restriction device may include a distal end configured to couple to a catheter assembly, a proximal end configured to couple to a fluid collection device, and a body extending from the proximal end to the distal end. The body may include an outer surface and an inner surface defining a lumen of the body. The flow restriction device may further include a fluid pathway disposed between the distal end and the proximal end when the outer surface is coupled within a mating luer. The fluid pathway may include a non-linear portion on at least a portion of the outer surface along which a fluid flows from the distal end into the fluid collection device.

The present disclosure provides a body-insertion device for a body, which comprises a first moving unit for moving an image acquisition unit; an insertion unit; and a second moving unit for moving the insertion unit. The first moving unit comprises at least one of a 1-1 module for moving the image acquisition unit in a 1-1 direction, a 1-2 module for moving the image acquisition unit in a 1-2 direction, and a 1-3 module for moving the image acquisition unit in a 1-3 direction. The second moving unit comprises at least one of a 2-1 module for moving the insertion unit in a 2-1 direction, a 2-2 module for moving the insertion unit in a 2-2 direction, and a 2-3 module for moving the insertion unit in a 2-3 direction.

A push-type blood collection needle includes a housing having an accommodating cavity therein, a rear cover and a needle body disposed in the accommodating cavity. The rear cover is movably disposed on the housing, and the rear cover has a supporting leg extending into the accommodating cavity. The needle body is provided with a rib. The accommodating cavity is internally provided with a projecting part that cooperates with and blocks the bottom of the rib. The supporting leg is provided with a stopper that cooperates with and blocks the side wall of the rib. And an elastic member is disposed between the needle body and the rear cover.

The present invention relates to a whole blood and fingertip blood testing device, including a blood collection structure and a testing chamber connected to and in fluid communication with the blood collection structure. The blood collection structure includes a collection rod, a capillary channel is arranged inside the collection rod, the bottom end of the capillary channel is located at the tail end of the collection rod, and the top end of the capillary channel is located in the middle of the capillary channel; and the collection rod is provided with a communicating hole connected to and communicated with the top end of the capillary channel. Moreover, the present invention also provides a method for collecting and testing a blood sample by using the testing device. Through the integrated structure of the blood collection structure, the testing chamber and the buffer chamber, the whole blood and fingertip blood testing device and method achieve functions of collecting, slowly releasing and testing the blood sample. The operation is easy, which reduces the difficulty of use by the operator. The number of times and time that the operator contacts the sample are effectively reduced, and the infectious possibility of the operator is reduced, so that the testing device is suitable for HIV testing, novel coronavirus testing, etc. The testing device and method have low requirements on the collected amount of the sample, and the collected amount is optimized from the milliliter level to the microliter level.

Systems and methods of use for continuous analyte measurement of a host's vascular system are provided. In some embodiments, a continuous glucose measurement system includes a vascular access device, a sensor and sensor electronics, the system being configured for insertion into communication with a host's circulatory system.
