An oral irrigator tip (or broadly an accessory for an oral hygiene device) may include an outlet, and a filtering element configured to filter a fluid flow to the outlet (e.g., through a tip body). The filtering element may be positioned to be in fluid communication with a chamber configured to hold an oral agent to be delivered to a user's oral cavity. A releasable connection may secure the tip body in a use configuration. The filtering element (e.g., a filter or screen) may be associated with (e.g., secured to, held by, etc.) the body.

A dosage control system includes a syringe and a dosage control module. The syringe includes a barrel and a plunger. The plunger includes a plunger seal located within the barrel and the barrel includes an end configured to connect to a needle. The dosage control module measures a first distance between the plunger seal and the end of the barrel, measures at least one second distance between the plunger seal and the end of the barrel, determines whether a predetermined amount of medication has been administered from the syringe based on a difference between the first distance and the at least one second distance, and selectively activates at least one of a visual indication and an audio indication if the predetermined amount of medication has been administered from the syringe.

A device for irrigation and/or insufflation during endoscopic surgery/procedures in a body cavity, comprising a first fluid pump device to deliver fluid to the body cavity, a second fluid pump device to move fluid from the body cavity, a control unit connected to the first and/or second fluid pump device, a blood pressure measuring device, wherein the control unit derives a control signal based on a signal from the blood pressure measuring device, and sends the control signal to the first fluid and/or second fluid pump device, wherein the control signal is derived by processing the signal from the blood pressure measuring device using a correlation factor in the device, dependent on the relationship between a blood pressure measurement signal, and a perfusion pressure of the body cavity, wherein the first and/or second fluid pump device controls the pressure in the body cavity based on the control unit's control signal.

Aspects of the present invention provide a method and a remote-controlled guidance system for delivering and applying medicines to a region of the body that may not otherwise be easily accessible (e.g., to the perianal region). The system is designed to enable the user to administer their medicine at a desirable angle they control, while the user is in a relatively comfortable and efficacious position for the treatment. The device can present a safer, more hygienic, and more effective alternative method to self-administer perianal medicines than any option currently available. To this extent, the system can present a discreet, hands-free alternative to the current options, or couple to other system, such as a bidet toilet seat system, thereby substantially eliminating any discomfort, ineffectiveness, and/or embarrassment a user might otherwise experience.

A tube end (14) of a barrel (12) of an injector (1) includes a tubular portion (921) on which a spiral projection (925) is formed, and an inner circumferential surface of the tubular portion is a female tapered surface (922). A small-diameter portion (16) is formed between a liquid storing portion (15) into which a plunger (18) is inserted and the tubular portion (921). A base end (21) of a liquid collection needle (20) is fluid-tightly connected to the small-diameter portion (16), and a leading end of the liquid collection needle (20) protrudes from the tube end (14).

Described are devices, systems, and methods for processing adipose tissue for reintroduction into a body. In some embodiments, adipose tissue is mixed with an additive prior to reintroduction.

A medical device has a base having an internally tapered wall mounted to a neck of a tube holder that has a reverse taper, so that rotation of the base relative to the neck may be effected with a controlled drag to provide a smooth and secure relative rotation. The base may be rotated relative to the holder by rotationally moving a needle protection housing hingedly attached to the base. The housing may be rotated to any orientation relative to the tube holder so long as a torsional force greater than the predetermined friction between the tapered surfaces is applied thereto. The base is designed to have a ring at its base that biases against the base of the neck in a self-adjustable manner. Other devices may also be fitted with reverse tapered complementary connection fittings to securely couple to each other.

A syringe calibrated for use with a single predetermined medication including a barrel having an internal reservoir volumetrically calibrated to contain the medication, a plunger received within the barrel, a first set of graduated indicia marked on the barrel indicating a first predetermined patient characteristic expressed in one of kg, max kg, lb, max lb, m.sup.2, and max m.sup.2, a second set of graduated indicia marked on the barrel indicating a second predetermined patient characteristic, different from the first predetermined patient characteristic, and expressed in one of kg, max kg, lb, max lb, m.sup.2, and max m.sup.2, and graduation lines marked on the barrel.

Provided are surface-modified elastic bodies (e.g. gasket for syringes) each obtained by a surface modification method for modifying a rubber vulcanizate or a thermoplastic elastomer, the method being capable of providing surfaces with excellent properties such as excellent sliding properties, excellent durability against repeated sliding motion, and excellent performance in preventing adsorption and aggregation of proteins, and allowing the surfaces to maintain the sealing properties, without using expensive self-lubricating plastics. The invention relates to surface-modified elastic bodies (e.g. gasket for syringes) at least partially having a surface modified by a surface modification method including: step 1 of forming polymerization initiation points on a surface of an object to be modified that includes a rubber vulcanizate or thermoplastic elastomer, and step 2 of radically polymerizing a monomer containing a CN bond in a molecule thereof, starting from the polymerization initiation points, to grow polymer chains on the surface of the object.
