INTERCHAN~EABLB PNEUMATIC CONNECTOR
FOR B~OOD PR~URE MONITOR8 Field of the Invent$on The present invention relates to patient monitoring device6 and, in particular, to fittings for providing interchangeable connection of such devices to the operable patient portions of the devices.
Bac~around of the Invention Many devices have been developed for the non-invasive determination of blood pressure in a patient. These devices comprise a bladder in the form of an attachable, adjustable cuff which is placed in a surrounding relationship on a patient's limb juxtaposed an artery for providing the pressure measurement, and a microprocessing device for reading the data generated through the cuff or bladder. The cuff or bladder is connected to the microprocessor throuqh a tubing set and a transducer. In operation, the device inflates the cuff by supplying pressurized air through the tubing to the bladder in order to occlude the artery. Various manipulations of the air pressure within the cuff are provided by adjusting the pressure within the cuff and reading the response through the transducer to such reductions in the pressure. The transducer converts the pressure manipulations into electri~al signals for computation by the microprocessor.
In order to appropriately measure the blood pressure in a variety of patients, different cuff sizes are provided.
These cuff sizes may range from a very small neonatal cuff to a large thigh cuff for an adult. Each of these cuffs must be attachable to a monitoring device for determining the blood pressure of the patient. Although the cuffs are .:
" :
, ~` 2~85l~
relatively universal in size and construction, the devices and the method by which they manipulate the information received through the pressurization of the cuff are different. These different devices have different set-ups for attaching the cuff to the monitoring device. These attachment devices may be a threaded, bayonet style connector or, for example, a male luer fitting at the end of a tube extending from the basic processing unit. This required maintaining an inventory of cuffs which were particularly suited for the particular monitoring device.
Thus, the interchangeability of cuffs was greatly limited.
~ummarv of tho Inventio~
It has been found desirable to have an interchangeable fitting on a blood pressure cuff such that a patient may be attached to a specific type of monitoring device, detached from that device for transportation or for exchange of device and reattached to a different type of device without removing the cuff. In order to provide for this, a fitting is provided at the end of the tubing which extends from the cuff. The fitting is adapted to receive a tube associated with a pneumatic device and includes a first end having a tube attachment means formed thereon and a second end which comprises an external surface defining a male thread and an internal surface defining a female taper. Advantageously, the internal surface may define a female luer fitting for receiving an associated male luer fitting from the monitoring device.
Alternatively, the second end may further include an internal cylindrical surface which receives an associated bayonet fitting which is clamped in place by the external surface which defines the male thread.
The tube attachment means provided at the first end of the :, , , :
~ ~ ~ O X 5 il fitting may be a tapered external surface or may be a barbed formation for holding the tubing thereon.
Additionally, the surface may merely be cylindrical if fiufficient interference fit is provided between the fitting and the tubing in order to maintain the connection under the pressure which will be applied to the cuff through the tubing.
Additionally, a shoulder portion of widened diameter may be provided intermediate the first and second ends in order to provide a gripping section to the fitting. This gripping section may be provided in order to assist in the threading of the connections of the second end or the insertion of the luer fittings into the second end of the fitting.
Thus provided, the f itting creates a blood pres6ure cuff apparatus for use with a non-invasive blood pressure monitor which apparatus includes a bladder for inflation in the cuff. A tube communicates with the bladder at a first end of the tube for inflation and deflation of the bladder, and a fitting is received at a second end of the tubing set. This fitting includes a threaded attachment ~eans on an outer surface of a second end and a second attachment means for selective attachment to a blood pressure determining device.
The threaded attachment mean~ is preferably a male thread, and the fitting may define an internal cylindrical surface which, in connection with the male thread, receives and attaches a bayonet-type fitting. Alternatively, the second attachment means may be an internal tapered surface whic~ forms a female luer fitting which receives a male luer fitting at the end of a tubing set or extending from ~2~ Q~8~
the body of a monitoring device. The luer fitting may be spaced from the end of the fitting in order to provide the space necessary for the cylindrical surface of the associated bayonet-type fitting.
Brief Description of the Dra~in~s Figure 1 is a perspective view of a fitting for a tubing set according to the present invention;
Figure 2 is a longitudinal cross-sectional view of the fitting of Figure 1; and Figure 3 is a perspective view of a cuff tubing set with fitting.
Desaription o~ the Preferred Embodiments Referring to Figure 1, the fitting of the present invention will be described and below the operation and use of the fitting will be described in connection with Figure 3. The fitting 1 has a tubing end 2 with an external surface 3. The external surface 3 has barbs 4 formed thereon for retaining a tubing set thereover. The barbs 4 are formed in a known manner at a maximum external diameter slightly larger than the internal diameter of the tubing set. The tubing set has the tubing end 2 of the fitting inserted therein thus deforming the tubing set radially outward in order to provide a frictional fit over the barbs 4.
The device end 5 has a surface 6 which defines a series of male threads 7. The male threads 7 are adapted to receive the female threads of a connector from a blood pressure monitoring device. This device may be of any known type and should have female threads of like pitch and depth to :: ' ' .~
~ ~ o ~
the male threads of the fitting. The male threads of the fitting should be chosen so as to provide a sufficient hermetic seal with the supply tubes of the device to operatively connect the fitting to the device and, S therefore, operatively connect the cuff.
Referring to Figure 2, the internal construction of the fitting is easily seen. The fitting defines an internal cylindrical surface 8 at a distal end of the fitting.
This cylindrical surface 8 is sized to receive the bayonet portion of the threaded connector described above. The bayonet portion is received internally of the fitting while the female threaded portion of the device attachment mechanism threads on the external surface of the fitting.
Thus, the combination of the threaded attachment and the receipt of the bayonet within the internal cylindrical surface 8 provides the necessary hermetic seal to the device.
The internal construction further defines an internal taper of a female luer fitting 9 which is adapted to receive a luer fitting on the device tubing set. Thus, the female luer fitting and the threaded male connection of the fitting end may be used in an alternative fashion.
That is, if the device to be attached to the cuff has a male luer fitting, it is received within the fitting and sealed to the female luer fitting 9. However, if the device has a female threaded attachment mechanism, the bayonet of the attachment mechanism is received adjacent the internal cylindrical surface 8 with the female threaded portions of the attachment mechanism being threadedly received on the outer surface of the fitting.
A passage 10 is defined by the remainder of the fitting în .
~as~
order to provide communication from one end of the fitting to the other end of the fitting. The passage and the sizing of the internal formations on the device end of the fitting are adapted to permit sufficient air flow through the fitting so as not to interfere with the operation of the monitoring device. That is, the passage must be shaped and sized so as not to provide a significant constriction to the passage of the air therethrough either during the inflate or deflate portions of the cycle.
The fitting is formed out of an engineering metal or a plastic, for example, brass and polycarbonate.
Conveniently, the fitting may be injection molded from plastic which, once formed, is rigid with respect to the tubing set. A representative fitting may have a length of approximately 0.875 inch and an internal passage diameter of 0.125 inch. The threaded end is formed with an external diameter of 0.390 inch and a thread pitch of 24 threads per inch.
Referring now to Figure 3, the use of the device is shown.
A cuff 11 is provided with a tubing set 12 extending from the cuff and in communication with a bladder within the cuff. The fitting 1 is received in interference fit at an end of the tubing set extending from the cuff. The second end of the fitting receives a threaded-type female connector 13 which extends from a tubing set attached to and in communication with the monitoring device. This tubing set is shown as having a free end 14 as it may be attached to any known type of pneumatic monitoring device.
Without removing the cuff 11 from a patient, the fitting 1 may be detached from the monitoring device by unthreading the connection with the tube extending to the pati~nt monitoring device. The patient may then be ~' '.''' , 21008~
transported or merely have a different device attached.
If the patient i8 transported, a transportable monitoring device may be used or a different monitoring device at the end of the transportation. The transport monitoring S device or the second monitoring device need not have the same type of threaded fitting as is shown in Figure 3 but rather may have a luer-type fitting for attachment to the cuff. Thus, the cuff may be attached to different types of tubing sets without removing the cuff from the patient.
In order to easily grip the fitting 1, a shoulder 15 is formed having a grip surface 16. The grip surface may be serrated to provide better grip. The wide diameter of the shoulder 15 increases the grip leverage and provides a stop for the tubing 12 to abut.
The invention will now be described with reference to the accompanying claims. It should be understood that the description given herein is merely representative, and the scope of the invention claims should be determined with reference to the attached claims.
