Abstract

The invention relates to a disposable temperature-measuring catheter. The disposable temperature-measuring catheter is characterized in that a connector (9) is arranged in a port of a taper rinsing interface (8) of the catheter; a lead (7) is fixed in a center hole of the connector (9); one end of the lead (7), provided with a thermistor (6), is arranged in an inner hole of a rinsing cavity and extends into one end of the catheter, and a changeover plug (10) is arranged at the other end of the lead (7). The product is disposable, simple in structure, low in cost and convenient to use, the problem of cross contamination caused by repeated use for a plurality of times is solved, and particularly, the problems of temperature test when a patient is in an operation or emergency treatment or the patient inconveniently moves and comparison of the shell temperature and body temperature are solved. The product can be directly inserted into the bladder of the patient in a non-invasive way. A temperature probe can continuously and accurately measure and monitor the body temperature; any external power supply is not required; the accuracy can be up to +0.2 DEG C to -0.2 DEG C; and accurate information can be timely fed back to related medical personnel.

Description

A thermometric property catheter

Technical field

The present invention relates to a kind of medical apparatus and instruments, relate in particular to an a kind of thermometric property catheter.

Background technology

At present; To the rapid rewarming after patient body's outer circulation the time,, the urgent patient is used the PAC thermometric usually because the bladder temperature is relevant with pulmonary artery; If but PAC is taken away; Or the thermometric failure, because these patients, so just can't monitor the interior temperature of body usually by plug in catheter.

Summary of the invention

The object of the present invention is to provide a kind of can be disposable, can directly insert bladder, but a thermometric property catheter of continuous precise take temperature;

For realizing above-mentioned purpose, the technical scheme that the present invention adopted is: thermometric property catheter of this kind, comprise multi lumen hose, and be provided with atria, inflatable chamber, flushing chamber in the multi lumen hose; On the circumference of catheter one incidence, be provided with several porus excretoriuses, be provided with flushing hole, and be provided with sacculus at the first half of one of catheter at its head; The other end of catheter is provided with drains cone-shaped interface, inflation cone-shaped interface, flushing cone-shaped interface; Drain cone-shaped interface respectively with multi lumen hose in set atria, porus excretorius be connected; The inflation cone-shaped interface respectively with multi lumen hose in set inflatable chamber, sacculus be connected; The flushing cone-shaped interface respectively with multi lumen hose in set flushing chamber, flushing hole be connected; On the inflation cone-shaped interface, is furnished with the inflated valve; On the drainage cone-shaped interface, is furnished with Bag for collecting urine; It is characterized in that: in the interface of the flushing cone-shaped interface of catheter, be furnished with union joint; In the union joint centre bore, be fixed with lead, lead is furnished with of critesistor and is assigned in the flushing intracavity hole, and stretches to one of catheter; Other end at lead is furnished with changeover plug;

A described a kind of thermometric property catheter is characterized in that: critesistor fits in the PVC cover, is provided with epoxy resin layer between PVC cover inwall and the critesistor outer surface and reinforces.

The present invention's beneficial effect compared with prior art:

This product is disposable use; Simple in structure, with low cost, easy to use; Solved the problem that is repeatedly used cross-contamination, when particularly having solved patient when operation or in first aid or the inconvenient temperature taking when movable of patient, and the contrast of temperature in the body surface body; These article can directly insert people's bladder, no wound, but the temperature probe continuous precise is measured monitoring body temperature, and does not need any external power supply, and precision can reach+and 0.2～-0.2 ℃, can in time feed back to the relevant accurate information of medical worker.

Description of drawings:

Fig. 1 is a front view of the present invention;

Among the figure:

1. inflated valve is 2. drained cone-shaped interface, 3. multi lumen hose, 4. porus excretorius, 5. flushing hole, 6. critesistor, 7. lead, 8. flushing cone-shaped interface, 9. union joint, 10. changeover plug, 11. inflation cone-shaped interfaces, 12. sacculus.

The specific embodiment:

Describe the present invention in detail below in conjunction with accompanying drawing:

As shown in Figure 1, this thermometric property catheter comprises multi lumen hose 3, is provided with atria, inflatable chamber, flushing chamber in the multi lumen hose 3; On the circumference of catheter one incidence, be provided with several porus excretoriuses 4, be provided with flushing hole 5, and be provided with sacculus 12 at the first half of one of catheter at its head; The other end of catheter is provided with drains cone-shaped interface 2, inflation cone-shaped interface 11, flushing cone-shaped interface 8; Drain cone-shaped interface 2 respectively with multi lumen hose 3 in set atria, porus excretorius 4 be connected; The inflation cone-shaped interface 11 respectively with multi lumen hose 3 in set inflatable chamber, sacculus 12 be connected; The flushing cone-shaped interface 8 respectively with multi lumen hose 3 in set flushing chamber, flushing hole 5 be connected; On inflation cone-shaped interface 11, be furnished with inflated valve 1, on drainage cone-shaped interface 2, be furnished with Bag for collecting urine;

The present invention is furnished with union joint 9 in the interface of the flushing cone-shaped interface 8 of above-mentioned prior art catheter, in union joint 9 centre bores, be fixed with lead 7, and lead 7 is furnished with of critesistor 6 and is assigned in the flushing intracavity hole, and stretches to one of catheter; Is furnished with changeover plug 10 in the other end of lead 7;

The silica gel of multi lumen hose 3 employings 100% of the present invention is processed, and replaces the latex catheter of prior art; There are some researches show that using the infection rate of silica gel urethritis is 1/10th of latex, is starkly lower than the catheter that latex material is processed;

Said critesistor 6 fits in the PVC cover, is provided with epoxy resin layer between PVC cover inwall and critesistor 6 outer surfaces and reinforces; Critesistor 6 parameters are 2252 Ω in the time of 25 ℃, 0～50 ℃ of probe temperature, precision+0.2～-0.2 ℃;

During use, changeover plug 10 is connected with instrument plug,, then instrument plug is allocated in the jack on the multi-parameter monitor this thermometric property catheter insertion patient's bladder; Resistance descends because NTC critesistor 6 raises with temperature, and temperature reduces and resistance raises, therefore, this change in resistance signal pass to the multi-parameter monitoring instrument circuit and on instrument successive reaction come out.
