摘要： A perforated medical adhesive tape has a tape backing layer formed from flexible sheet material, e.g., plastic film, and a pressure-sensitive adhesive layer for bonding the adhesive tape to the skin of a patient. The pressure-sensitive adhesive layer is flexible, deformable, elastic and has a permanently tacky surface. The backing layer has a planar outer surface with a multiplicity of upwardly extending protrusions, i.e., minute mounds which are upward deflections in the tape with corresponding upwardly extending, downwardly opening concavities or indentations in its lower surface below each of the protrusions. Each of the protrusions has a pierced opening located at its approximate center. The openings are elevated above the planar surface of the tape, and each opening extends through both the tape backing and the pressure-sensitive adhesive layer to facilitate the diffusion of air and moisture vapor through the tape. The tape is pierced with a multiplicity of heated needles, each having a tapered point. To control the size of the openings, the tape is pierced a predetermined distance by the heated needles. The heat of each needle expands each opening in the adhesive layer by melting and fusing the adhesive around the opening into the greater surrounding cooler mass of the pressure-sensitive adhesive layer.
摘要翻译：穿孔医用胶带具有由柔性片材例如塑料膜形成的带背衬层和用于将胶带粘合到患者皮肤的压敏粘合剂层。压敏粘合剂层是柔性的，可变形的，弹性的并且具有永久粘着的表面。背衬层具有平坦的外表面，其具有多个向上延伸的突出部，即在带中的向上偏转的微小的墩，在每个突起下方的下表面中具有相应的向上延伸的向下开口的凹陷或凹陷。每个突起具有位于其大致中心处的穿孔。开口在带的平面表面上方升高，并且每个开口延伸穿过带背衬和压敏粘合剂层，以促进空气和湿气蒸气通过带的扩散。胶带用多个加热的针刺穿，每个具有锥形点。为了控制开口的尺寸，通过加热的针刺穿预定距离的带。每个针的热量通过熔融并将开口周围的粘合剂熔合并粘合到压敏粘合剂层的较大周围的冷却剂块中来扩大粘合剂层中的每个开口。

摘要： A solid, multipurpose, flexible, ultrasonic biomedical couplant hydrogel in sheet form is applied to the skin of a patient to facilitate the transfer of ultrasound energy between a standard ultrasound instrument and the body. The couplant sheet has broad upper and lower surfaces and a narrow peripheral edge which is usually circular, square or rectangular but can have other shapes such as the shape of the part of the body being monitored. During use, the lower surface of the sheet is applied to the skin of a patient and remain in place throughout use. The ultrasound instrument is then passed back and forth, usually in contact with the exposed upper surface of the hydrogel sheet while ultrasound energy is transmitted through the hydrogel which serves as a transmission path for the sonic energy passing to and from the body of the patient. The hydrogel sheet of the present invention is a flexible, self-supporting solid sheet which holds its form during storage and when placed on the body. The sheet contains water and a humectant such as triethylene glycol or glycerin and a network of long hydrophilic polymer molecules that hold the liquid in place and give solidity to the hydrogel sheet The polymer can comprise polyacrylamide, karaya gum or a modified starch.

摘要： A hydrogel matrix is provided for a multipupose medical electrode having an electrically conductive backing. The matrix comprises a dispersion of a natural or a synthetic hydrophilic polymer, e.g., polyacrylamide, polyacrylic acid, modified starch, or gum karaya, gum acacia, locust bean gum or the like, water, and a humectant such as triethylene glycol or glycerol. The matrix is a flexible sheet having a tacky lower surface for establishing a bond to provide electrical contact with the skin of a patient. The matrix has a resistivity greater than the resistivity of the electrical conductive backing and includes a gelation inhibitor such as a salt of a weak acid, e.g., Mg(OAc).sub.2 uniformly distributed within the matrix in an amount sufficient to retard gelation of the matrix prior to forming the matrix into a flexible sheet.

摘要： A reusable temperature sensing probe assembly comprises a temperature sensor strip extending from one end of a handle. The temperature sensor strip carries at least one temperature sensor for measuring temperature within a body cavity of a person, such as the rectum. The handle/temperature sensor strip is reversibly positionable within a unitary balloon/sleeve assembly comprised of a balloon portion and a sleeve portion. The balloon portion is comprised of a first interior space configured to hold the temperature sensor stip and a second interior space separate from the first interior space that is configured for inflation. An inflation tube has one portion sealed within the second interior space of the balloon portion and a second portion which extends through the sleeve portion for connection to a fluid source.

摘要： A dual purpose biomedical device has a solid flexible ultrasonic couplant sheet or pad formed from an electrically conductive hydrogel. The hydrogel sheet has an upper surface that is exposed during use for allowing direct contact between an ultrasonic generator and the hydrogel sheet and a lower surface that is placed during use against the skin of a patient whereby the hydrogel sheet transmits ultrasonic waves to and from the body of the patient. An adhesive is operatively associated with the hydrogel sheet for adhering the sheet to the skin. A removable and replaceable electrically conductive flexible sheet is supported upon the upper surface of the hydrogel sheet for establishing electrical contact with the patient through the hydrogel sheet when lowered into contact with the hydrogel sheet. The conductive sheet is removable therefrom for allowing the ultrasonic generator to contact the hydrogel sheet.
