Definitions
- ABSTRACT Improved method and means is provided for detecting undesirable infiltration into the perivascular tissue of Field of Search 128/1 ,2, liquid which is normally administered intravenously or intraar- 2l3, 214, 214.2, DIG. l2, DIG. l3; 222/5 terially.
- the skin temperature in the region about the administration needle or catheter is monitored to provide an early warning of the condition causing liquid infiltration into the perivascular tissue of a patient. Since the liquid being administered to a patient is typically at a lower temperature than normal skin temperature, an undesirable accumulation of the administered liquid produces a resulting lower skin temperature in the region about the accumulation. A detected change in skin beyond a set value may thus be detected and used to terminate liquid administration to the patient and also to provide an alarm indicative of the undesirable liquid infiltration condition.
- FIG. 1 there is shown the arm 9, or other suitable body part of a patient, disposed to receive a liquid-administering needle or catheter 11 in a superficial artery or vein.
- The-needle or catheter 11 is connected through flexible conduit or tubing 13 to a liquid reservoir 15.
- Flow control means the detector which may be a signal-controlled valve or tubing clamp in gravity-fed infusion sets or a motor shutoff switch in positive pressure administration sets, or the like, is coupled to the liquid conduit 13 to stop the flow of liquid therethrough in response to a control signal applied thereto on input 19.
- a temperature-responsive transducer 21 such as a thermistor or thermocouple, or the like, is disposed preferably on the skin surface about the entrance of the needle or catheter 11 into a vein or artery.
- the output signal on line 23 from the transducer 21 is thus representative of the skin surface temperature and is applied to the detector means 25 for detection and analysis.
- the detector means 25 typically includes an amplifier 27 connected to receive the transducer output signal on line 23 and an adjustable threshold detector 29 connected to receive the output of amplifier 27 for producing a control signal at output 31 in response to the amplifier output attaining a selected threshold value.
- an initial indication of skin surface temperature may be obtained in the region of the entrance of the needle or catheter 11 into a vein or artery of a patient before liquid infusion or administration is commenced.
- the resultant signal may be stored using conventional signal storage means for comparison with subsequently generated signal values.
- This initial indication may thus be used as a reference indication against which a lower threshold value of skin temperature may be selected by adjustment of threshold detector 29.
- this initial skin temperature at the regionabout the entrance of the needle catheter l1 (and elsewhere on the patients body) is typically about 33 C. if the patient is not in a state of shock and tends to vary with liquid infusion only down to about 3 l C. for common infusion rates of liquids. These liquids are at or about room temperature i.e.
- the liquids are stored in a refrigerated state (e.g. blood).
- a refrigerated state e.g. blood
- the skin temperature in this region will drop well below the few degrees Centigrade difference which occurs during normal liquid infusion and will closely approach the temperature of the infusion liquid.
- This control signal may be applied either to an alarm, say, located at a central nursing station, or to the flow-control means 17, or to both the alarm 33 and the flow-control means 17.
- the liquid infusion is thus terminated automatically by flow-control means 17, or manually as by a nurse responding to the alarm 33 indication or abnormally low skin surface temperature in the entrance region and taking necessary corrective measures.
- the entrance region temperature for example, detected by transducer 21, is monitored with respect to a reference signal.
- an additional temperature transducer 35 may be disposed preferably on the skin surface of the patient 9 at a location which is remote from the entrance region transducer 21.
- the amplifier 27 amplifies the difference between signals from the transducers 21 and 35 for application to the threshold detector 29.
- the output from threshold detector 29 may also be used in this embodiment to actuate either or both of the alarm 33 and flow-control means 17.
- differential thermal detection may be accomplished by comparison of the output signal from transducer 21 with a signal from a reference source of such signal (i.e. instead of signal from transducer 35). This is possible because of reasonable uniformity of skin temperatures encountered at a given location on the body from patient to patient not suffering from the above-mentioned abnormalities.
- FIG. 2 there is shown a pair of transducers 21 and 35 disposed on a length of adhesive tape 41 for positioning on a portion of the body, say, an arm of a patient.
- the adhesive tape 4 usually has low thermal conductivity and may be disposed to encircle an arm or leg of a patient.
- Transducers 21 and 35 of FIG. 1 are attached to the inside surface of the tape 41 in position to contact the skin surface of the body part of a patient at spaced locations with the tape in place. Suitable conductors 23 to the transducers may be affixed to the tape 41 to avoid accidental snagging and circuit disconnection from the detector means 25.
- the present infusion detection apparatus and method provides early indication of liquid infusion into perivascular tissue about the entrance of a liquid conduit into a patients vein or artery.
- Such early detection may be produced by differential or absolute thermal measurements of skin surface temperature prior to the accumulation of the quantity of liquid commonly required to provide such presently used indications as swelling, skin discoloration, and pam.

- circuit means coupled to the output of said element and to said control means for applying a control signal thereto to stop liquid infusion into the patient in response to said output attaining a selected value.
- control means includes pinching apparatus disposed about a portion of conduit of the liquid-delivery conduit means for occluding the conduit to stop the flow of liquid therethrough in response to said control signal applied to said control means.
- said liquid-delivery conduit means includes motor-driven liquid-pumping means
- control means is coupled to said liquid-pumping means for stopping the pumping of liquid thereby in response to said control signal applied to said control means.
- said circuit means includes threshold detection means for producing said control signal only in response to said output attaining a preselected value.
- said circuit means includes a source of a reference signal which is representative of a selected absolute temperature of the skin surface of a patient;
- said threshold detection means produces said control signal only in response to a selected algebraic combination of the output from said element and said reference signal attaining a predetennined relationship.
- said circuit means includes signal storage means for storing a signal representative of the temperature of the skin of a patient in the region of said entrance site prior to liquid infusion into a blood vessel of the patient;
- said circuit produces said control signal in response to the difference between the stored signal prior to liquid infusion and the output of said element following commencement of liquid-infusion attaining a predetermined value.
- infusion-infiltration responsive apparatus as in claim 1 comprising:
- a source of reference signal which is representative of the surface temperature of the skin of a patient at a location remote from said site
- said circuit means includes threshold response means which produces said control signal in response to said output decreasing below said reference signal by a selected value.
- said source includes an auxiliary heat-responsive element disposed to be positioned at a location on the skin surface of a patient remote from said site for producing said reference signal representative of the skin surface temperature at said location;
- said threshold responsive means includes a differential detector which responds to the difference between said output and said reference signal for producing said control signal in response to said difference attaining a selected value.
- liquid-infusion administration comprising the steps of:
- the method of liquid infusion administration as in claim 10 comprising the additional step of sensing the temperature in said region of the entrance site prior to the infusion of liquid and wherein the step of discontinuing delivery of the infusion liquid is performed in response to the temperature sensed in said region following commencement of liquid infusion deviating by a preselected amount from the temperature sensed prior to infusion of liquid.
