Precision syringe

A precision syringe includes a syringe barrel and plunger that has a base, an internal portion, and an external portion. The internal portion of the plunger extends longitudinally into the syringe barrel. The internal portion has a first end coupled to the base and a second end that is configured to push fluid out of and/or suction fluid into the syringe barrel. The external portion extends longitudinally along an outer surface of the syringe barrel. The external portion has a first end coupled to the base and a second end that is configured to receive an applied force that causes the plunger to move relative to the syringe barrel so that the second end of the internal portion is actuated through a portion of the syringe barrel (e.g., to dispense fluid from or suction fluid into the syringe barrel).

An optical decoding system including an optical sensor integral with or attachable to a housing of a drug delivery device and configured to be directed at first and second rotatable components of a dose setting and dispensing mechanism of the drug delivery device and a processor configured to: (i) cause the optical sensor to capture images of the first and second rotatable components at least at the beginning and end of a medicament dose dispensing process; (ii) determine a rotational position of both the first and second rotatable components in each of the captured images; and (iii) determine from the rotational positions of the first and second rotatable components an amount of medicament delivered by the dose setting and dispensing mechanism of the drug delivery device.

Syringe pump having a pressure sensor assembly

A syringe pump is disclosed that includes a body, a syringe seat, a syringe actuator, a memory, and one or more processors. The syringe seat is coupled to the body. The syringe actuator is configured to actuate a syringe secured within the syringe seat. The memory is configured to store a plurality of instructions. The one or more processors, in accordance with the plurality of instructions, is/are configured to: prime the syringe pump in a prime phase; determine if an occlusion exists during the prime phase using a first test; stop the prime phase; initiate fluid delivery into a patient; enter into a start-up phase; determine if an occlusion exists using a second test during the start-up phase; transition from the start-up phase into a steady-state phase; and determine if an occlusion exists during the steady-state phase using a third test.

Sensing Complete Injection for Animal Injection Device
20210338402 · 2021-11-04 ·

A semi-automated veterinary medicine delivery device may sense whether and how much air may have been incorporated into a dose delivered to an animal. The device may also sense an incomplete injection in some cases, and may cause a second dose to be administered to make up for the incomplete dose. The device may compare a position sensor on a syringe in combination with a current sensor on a motor attached to the syringe to detect any abnormalities. In the case of an improper dose, the device may alert the user and administer a second dose.

Auto-injectors and associated assemblies and methods for delivery of medicament in a controlled manner are disclosed herein.

System and Method for Syringe Fluid Fill Verification and Image Recognition of Power Injector System Features
20230310758 · 2023-10-05 ·

A fluid injection system and a fluid verification system for confirming that a syringe, containing a fluid for injection, is fully filled with fluid and neither has free space (i.e., air) near the distal end thereof when the syringe is provided in an upright position nor contains air bubbles. Imaging processing techniques and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within a syringe.

OXYGEN CONCENTRATING DEVICE, WOUND CARE APPARATUS, AND TREATMENT METHODS
20230293869 · 2023-09-21 ·

A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply MEA, an oxygen consuming MEA, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.

Apparatus and method for detecting liquid level in a clear or partially clear container

A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that forms a vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection of the light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.

Electromagnetic actuation of elastomeric valve for fluid flow control

Actuation of an elastomeric valve with an electromagnet is disclosed wherein an elastomeric valve material may comprise a steel disc embedded in its wall to control the flow of fluid. In response to an electric current being applied to an electromagnet, a magnetic field attracts a disc embedded in the elastomeric valve material. The elastomeric valve would then move towards the electromagnet to create a seal, thereby blocking the flow of fluid.

Systems, apparatuses and methods for capturing images of medical condition management events and related equipment with smartphone and related app that processes images to reduce medical errors

Device(s) with camera and medical event image capture app and method(s) are provided to capture images of medical condition management events involving products with indicia, perform image processing and analysis of captured images to discern product characteristics, artifacts and/or related informatics from indicia and other image elements in the captured image, and perform human machine interaction (HMI) operations or other logical operations that alert a user regarding a selected informatic or request input or otherwise educate the user about an aspect of medical condition management. The medical event image capture app provides any one or more of confirmation of correct or compatible product(s), dose confirmation, and detection of defective product or medication or misuse. The medical event image capture app provides auto-recording of medical event data into patients' electronic records, and assists with healthcare administration including billing, medical products inventory management and reordering, care plan compliance, and clinical effectiveness.
