Medical gloves are disclosed with one or more channels running from a cuff of the glove to the tip of one or more fingers. The channel may extend at least partially around the fingertip and may comprise a one or more orifices positioned at least partially around the fingertip. A suction source may be coupled to the channel to provide suction at the orifices.

The invention relates to a negative pressure drainage device attached to dental tissue. The negative pressure drainage device has a negative pressure machine, a negative pressure tester, a negative pressure control valve and a sealing part. The negative pressure machine is connected to the negative pressure tester, the negative pressure tester is connected to the negative pressure control valve, and the negative pressure control valve is connected to the sealing part through a connecting part. The device, by using the apical foramina structure of the dental tissues per se, cannot only drain and form negative pressure in the cyst cavity, but also no longer need a long-term implantation of a negative pressure drainage artificial device in the jaw.

A dental valve device is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, a partial opening formed in the valve body and a rotatable valve sealing body adapted to be inserted into the partial opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving opening and a hose receiving opening, the rotatable valve sealing body having a check valve positioned in the bore.

Apparatus and methods are described, including apparatus for treating a cavity in a human body, the apparatus including a delivery tube. A bather device has a collapsed configuration and an expanded configuration, the barrier device moving from the collapsed configuration to the expanded configuration upon being deployed from the delivery tube. A pushing element, slidably disposed within a lumen of the delivery tube, is configured to deploy the barrier device from the delivery tube by pushing the bather device. One or more bather-deployment elements are coupled to the barrier device and to the pushing element, the bather-deployment elements being configured to conformingly contact the barrier device with tissue surrounding the cavity. Other applications are also described.

Due to the low suction strength or an unsuitable positional relationship or distance between the suction feed and the oral cavity, conventional extra-oral intake devices exhibit the problem of not being able to fully suck particulate matter and droplets from teeth, shavings from repair products, saliva, bacteria, blood, rinse water, tooth surface cleaning agents, etc., that are dispersed to outside the oral cavity during practice. In order to improve suction strength, the present invention provides an intake device that is equipped with a protruding airflow-regulating member, the top of which is oriented in the direction in which the fluid flows into the opening part of the suction feed, and that can efficiently suck dispersed particulate matter and droplets within a wide range.

A dental pain and discomfort notification system for providing immediate feedback from a patient to a dentist, dental hygienist, or oral surgeon. The dental pain and discomfort notification system includes a notification panel mounted in proximity to a dental chair and an activation device. The activation device may be a hand-held device, such as a wireless remote, or may be mounted near the dental chair. The activation device includes one or more switches for activation by the patient. Each switch corresponds to a condition being experienced by the patient, such as pain, discomfort, or the need for suction. During a dental procedure, the switches may be activated by the patient to request a corresponding action by the dentist.

The barrier device is configured to isolate the cavity from surrounding body fluid that is between the barrier device and the pushing element, following deployment of the barrier device from the delivery tube. Other applications are also described.

A novel chemi-luminescent cheek retractor, wherein: the chemi-luminiscence is not localized to a specific location but the whole cheek retractor has multiple compartments to provide adequate and uniform illumination. Further, the cheek retractor is reversibly inflatable; chemi-luminiscence is triggered by the using the nitrous and ozone gas that pumped in to selective multiple compartments; a fiber reinforced latch and adjustable screw is provided to control unrestrained opening or closing, thereby minimizing the damage due to the uncontrolled elastic reflex of the material to the device and due to the force exerted on the jaws of the patient; the chambers also lined with a reflective coating on the inner surface to aid in better and uniform illumination; a multi-function valve is provided at the split junction capable of allowing various reversible attachments e.g. a suction tube, one LED diode-charged, wireless transmitter, camera etc.

The invention is about a dental suction arrangement which removes saliva and other fluids from a person's oral cavity. The suction arrangement includes a suction tube (101) and an absorption body (111) to be placed in the oral cavity. The suction tube (101) includes a suction part (103) which is arranged in the absorption body (111) and which is equipped with hole members (104) communicating with the absorption body (111). According to the invention, the suction arrangement is made of elastically deformable material in order to adapt to the anatomical shape of the bottom of the mouth.
