Abstract
A dilator for use in a bovine animal's teat for controlling the flow of fluid from the teat is packaged in an envelope containing a disinfectant solution. A collapsible dispensing bag containing material, as antibiotics, is located within the envelope. An elongated dispensing tube connected to the bag carries the material from the bag to the teat duct accommodating the dilator. The envelope has releasable seals which permit the envelope to be opened to expose the dilator. The envelope is used as a cover to maintain the dilator in a sterile condition as it is inserted into the duct of the teat. The material in the bag is moved from the bag by applying a squeezing force to the envelope and bag. After all of the material is squeezed from the bag, the dispenser and envelope are removed from the teat and dilator.
Claims48
An apparatus for dispensing material into the milk duct of a cow's teat comprising:
- a dilator having means insertable into the milk duct and a one-way valve to restrict movement of material into the milk duct, an envelope having a chamber accommodating the dilator, and dispensing means located in said chamber, said dispensing means having a flexible bag accommodating the material to be dispensed into the milk duct, and means to carry the material from the bag through the one-way valve and into the milk duct when the dilator is inserted into the milk duct.
An apparatus for dispensing material into a passage of a body comprising:
- first means adapted to be located in the passage, said first means having a tubular body having a passage and a one-way valve operable to restrict movement of material into said passage of the body, an envelope having a chamber accommodating the first means, and second means located in said chamber of the envelope operable to dispense material into the passage of the body, said second means having a bag accommodating material to be dispensed, and tubular means to carry the material from the bag through the one-way valve and passage in the tubular body to the passage of the body when the first means is located in the passage of the body.
An apparatus for dispensing material into a passage of a body comprising:
- first means adapted to be located in the passage, said first means having a one-way valve operable to restrict the movement of material into said passage, said one-way valve includes a pair of flexible side walls, said side walls terminating in lips surrounding a normally closed mouth, an envelope having a chamber accommodating the first means, and second means located in said chamber of the envelope operable to dispense material into the passage, said second means having material to be dispensed into said passage and carrying the material to the passage when the first means is located in the passage.
An apparatus for dispensing material into a passage of a body comprising:
- first means adapted to be located in the passage, said first means having a one-way valve operable to restrict movement of material into said passage, an envelope having a chamber accommodating the first means, and second means located in said chamber of the envelope operable to dispense material into the passage, said second means includes a bag accommodating the material to be dispensed and means to carry the material from the bag to the passage when the first means is located in the passage.
An apparatus for dispensing material into a passage of a body comprising:
- first means adapted to be located in the passage, an envelope having a chamber accommodating the first means, and second means located in the chamber of the envelope operable to dispense material into the passage, said second means including bag means accommodating material to be dispensed and means to carry the material from the bag means to the passage when the first means is located in the passage.
A method of dispensing material into the milk duct of a teat of an amimal with a dilator located within an envelope, a flexible bag located within the envelope, and tubular means connected to the bag for carrying material from the bag through the dilator and discharging the material into the milk duct comprising:
- opening the envelope to expose the dilator, inserting the dilator in the milk duct of the teat from the discharge end thereof, dispensing the material in the bag into the milk duct by compressing the bag to force the material in the bag to move through the tubular means into the milk duct, and removing the envelope, bag and tubular means from the dilator, said dilator remaining in the milk duct of the teat.
A method of dispensing material into a passage of a body, said passage having a discharge end, with means adapted to be located in the passage, said means being located within an envelope, a flexible bag located within the envelope, and tubular means connected to the bag for carrying material from the bag through the means and discharging the material into the passage comprising:
- opening the envelope to expose the means, inserting the means in the passage from the discharge end thereof, dispensing the material in the bag into the passage by compressing the bag to force the material in the bag to move through the tubular means into the passage and removing the envelope bag and tubular means from the means, said means remaining in the passage.
