Abstract
Description
Title of the invention: Medical device, in particular for supplying NO, equipped with a device for attachment to an elongated support
[0001] The invention relates to a medical device, in particular a device for supplying NO, such as a NO / nitrogen mixture, equipped with a fastening device for fixing, i.e. hanging and holding, the device to an elongated support of the rod or bar type.
[0002] During their use, certain medical devices must be fixed, i.e. hung and held in position, on supports having different structures, typically rod or bar type supports having square, rectangular or cylindrical sections.
[0003] Thus, certain NO delivery devices, i.e., typically NO / N2 mixing devices, must be transportable in emergency vehicles, such as an ambulance, aircraft, or other. During transport, to prevent them from falling, they must be securely fastened to a support arranged in the vehicle (e.g., a rectangular or square rod) or to the stretcher (e.g., a cylindrical bar) on which the patient receiving NO via these devices is located. An example of an NO delivery device is described by EP-A-3906955.
[0004] To this end, it is common to arrange a fastening device on the casing or peripheral shell of the medical device. For example, EP-A-3639975 teaches a clamping device for attaching a device to supports of different sizes and shapes. It consists of a lower part comprising a concave lower jaw and a rear extension forming a first clamping handle, and an upper part comprising a concave upper jaw and a rear portion serving as a second handle. These parts have several pivot points allowing the two parts to pivot. Two axes also serve as anchor points for a locking arm used to adjust the jaw opening. A rotating adjustment knob arranged around the locking arm allows its length, and therefore the jaw opening, to be adjusted.However, such a clamp structure is complex and difficult to manipulate; in particular, the presence of the rotating adjustment wheel complicates its architecture.
[0005] The problem is therefore to propose a medical device, in particular a device for supplying NO, such as a NO / nitrogen mixture, equipped with a fixing device allowing the medical device to be fixed to a support such as a rod or bar, avoiding or limiting all or part of the aforementioned problems, risks and / or disadvantages.
[0006] The solution of the invention relates to a medical device comprising a frame, i.e. an external peripheral shell, comprising an outer wall and a device for attaching it to an elongated support, such as a rod or bar, arranged on the outer wall of said frame, characterized in that:
[0007] - the fastening device comprises a clamp body and a movable clamp element one in relation to the other,
[0008] - the fastening device comprises a first (A) and a second (B) location separate components used to attach the fastening device to one or more supports, such as a rod or bar,
[0009] - a part of the gripper element is configured as a first jaw including the first location A,
[0010] - shoulders are arranged on the body of the clamp, on either side of the element of a clamp, forming a second jaw, the first and second jaws facing each other and forming a first clamping clamp comprising the first location A,
[0011] - the gripper body is configured into a third jaw and part of the element the movable clamp is configured with a fourth jaw, said third and fourth jaws facing each other and forming a second clamping clamp comprising the second location and
[0012] - a manipulator, operable by a user, cooperates with the element of the gripper, when activated, to move the gripper element respectively to the gripper body and to bring the third and fourth jaws closer together or further apart.
[0013] Depending on the embodiment considered, the device of the invention may comprise one or more of the following features:
[0014] - the clamp body and the clamp element are carried by a support plate.
[0015] - the mounting plate includes a screw-fixing plate, in particular drilled of mounting holes.
[0016] - the gripper body and the gripper element are supported by a support plate of screw fixing.
[0017] - it comprises, arranged within its casing, an internal gas circuit for conveying a gas, means of controlling the flow of gas conveyed by the internal gas circuit, and means of control to control the means of controlling the flow.
[0018] - the internal gas circuit includes at least one or more gas passages.
[0019] - the flow control means include one or more valves, in particular a or solenoid valves.
[0020] - the control means comprise at least one electronic card bearing a (or des) microprocessors implementing one or more algorithms.
[0021] - it includes flow and / or pressure sensors arranged on the gas circuit internal.
[0022] - it includes means for connection to one or more gas sources, by particular to a (or several) pressurized gas cylinder(s), in particular of NO / N2 gas mixture and / or oxygen.
[0023] The device is a device for supplying gaseous NO, in particular a gaseous NO / N2 mixture, intended to be connected to the patient circuit of a medical ventilator supplying a respiratory gas, in particular an N2 / O2 mixture, pure oxygen or air.
[0024] The invention will now be better understood with reference to the following detailed description, given by way of illustration but not limitation, with reference to the accompanying figures, among which:
[0025] [Fig-1] represents a fixation device according to the invention for a medical device, to to know here a device for supplying gaseous NO,
[0026] [Fig.2] illustrates the attachment of the medical device equipped with the clamping device of [Fig.1] to a horizontal rod with a square or rectangular cross-section,
[0027] [Fig.3] illustrates the fixing of the medical device equipped with the clamping device of [Fig.1] to a vertical cylindrical bar.
[0028] [Fig.1] represents a clamp-type fastening device 1 intended to equip a medical device 30, namely here a device for supplying gaseous NO.
[0029] This fastening device 1 is carried by the rear face 31 of the external housing 32, i.e., the frame or peripheral shell of the medical device 30, as illustrated in [Fig. 2] and [Fig. 3]. It comprises a fixed gripper body 2 and a movable gripper element 3, in particular pivoting (axis XX), carried by a support plate 4 comprising one (or more) plate 4.1, in particular metallic, pierced with several holes 4.2 for the passage of screws or the like, serving to fasten the support plate 4 by screwing it to the rear face 31 of the frame 32 of the medical device 30. In other words, the gripper body 2 and the gripper element 3 are carried by the screw-fastening support plate 4.
[0030] The fixing device 1 comprises a first A and a second B distinct location allowing the fixing device 1 to be fixed to supports of different shapes, either to a rod 40 of external section (i.e. perimeter) rectangular or square, as illustrated in [Fig.2], or to a bar 41 of cylindrical shape, i.e. of external section (i.e. perimeter) circular, as illustrated in [Fig.3], in particular a vertical bar 41.
[0031] The gripper element 3 is movable relative to the gripper body 2, which is stationary and fixed to the support plate 4. A rotating member 5, actuated by the user, cooperates with the movable gripper element 3 when the user actuates it, in order to move progressively, in particular tilt (AXIS XX), and thus operate a tightening of the rod 40 located in location A, as illustrated in [Fig.2], or of the cylindrical bar 41 located in location B, as illustrated in [Fig.3].
[0032] For example, clamping can be achieved by actuating the rotating member 5 clockwise and, conversely, loosening by actuating it in the opposite direction, i.e., counterclockwise. During clamping, the movable clamping element 3 pivots, i.e., tilts, progressively so that the horizontal rod 40 located in position A is gripped between a first shoulder 6.1 forming a first jaw 6 carried by the clamping element 3, in particular by the head of the clamping element 3, and two second shoulders 10.1, 10.2 forming a second jaw 7 carried by the fixed clamping body 2, as shown in [Fig. 2]. The first shoulder 6.1 may include, as here, a lip 11 or similar feature to better retain the rod.
[0033] The two second shoulders 10.1, 10.2 forming the second jaw 7 are supported by the gripper body 2 and arranged on either side of the pivoting gripper element 3 (axis XX), that is to say, they sandwich it. These two second shoulders 10.1, 10.2 form arms or similar features projecting away from the gripper body 2, that is to say, they protrude.
[0034] Similarly, during clamping, the movable clamping element 3 pivots progressively so that the cylindrical bar 41, here vertical, located in position B is clamped between the rear surface of the lower portion 8 of the clamping element 3 and an area 9 of the surface of the clamping body 2, as shown in [Fig.3].
[0035] The rear surface of the lower portion 8 of the clamp element 3 and the area 9 of the surface of the clamp body 2 form third and fourth jaws forming a clamping clamp to fix and retain a support.
[0036] In all cases, the tightening must be strong enough to prevent the device 30 from detaching from its support, i.e. rod 40 or bar 41, and from falling which could damage it and / or injure the person or persons in the immediate vicinity, in particular when the attachment is made to a cylindrical bar arranged vertically as in [Fig.3].
[0037] In other words, the invention relates to a medical device 30, in particular a device for distributing or supplying NO, especially a NO / nitrogen mixture, comprising a casing 32 including an outer wall 31 and a fastening device 1 to an elongated support 40, 41 arranged on the outer wall 31 of said casing 32, characterized in that:
[0038] - the fastening device 1 comprises a clamp body 2 and a clamp element 3 mobile relative to each other,
[0039] - the fastening device 1 comprises a first A and a second B location distinct components used for fixing the fixing device (1) to one or more elongated supports 40, 41,
[0040] - a portion of the gripper element 3 is configured as a first jaw 6 including the first location A,
[0041] - shoulders 10.1, 10.2 are arranged on the body of the clamp 2, on either side of the clamping element 3, forming a second jaw 7, the first and second jaws 6, 7 facing each other and forming a first clamping jaw 6, 7, A comprising the first location A,
[0042] - the gripper body 2 is configured into a third jaw 9 and a part of the movable clamping element 3 is configured as a fourth jaw 8, said third and fourth jaws 8, 9 facing each other and forming a second clamping jaw 8, 9, B comprising the second location B and
[0043] - a manipulation device 5, actuable by a user, cooperates with the element of clamp 3, when actuated, to move the clamp element 3 respectively to the clamp body 2 and bring the second and third jaws 8, 9 closer together or further apart, i.e. "open / loosen" or "close / tighten" the second clamping clamp 8, 9, B including the second location B.
