Description

Catheter anchoring system

Technical field

The present invention relates to the fixing medical apparatus and instruments of a kind of conduit, particularly a kind ofly multiple medical catheter can be fixed on to the fixture of patient to prevent that conduit from moving.

Background technology

Modern medical skill need to be applied multiple conduit as auxiliary treatment means according to different Therapeutic Method.Such as venous infusion catheter is for transfusion, catheter is for passive urethral catheterization and bladder irrigation, PICC periphery venipuncture conduit is for needing the patient of long-term intravenous transfusion, such as chemotherapy, parenteral alimentation etc., arterypuncture conduit is applied to need the shock patient first aid of quick blood transfusion or to anaesthesia patient monitoring arterial pressure, carries out blood gas analysis etc.Also have various drainage tubes, epidural catheter etc. are for different clinical practices.

All conduits enter human body for realizing different Therapeutic Method via patient's physiology tract or artificial path, reach the object for the treatment of.But no matter which kind of conduit, inserts human body through distinct methods, arrives after treatment position, all need reliable and effective fixingly, prevent accidental.Once because there is the non-controllability displacement of conduit, loosening, even slippage, all can cause negative effect in various degree to patient and treatment.Once such as the unexpected slippage of venous infusion catheter, patient has to face the misery of secondary puncture, even impact treatment.In clinical practice operation, sometimes for effective A/C, such as drainage tube, even need on patient skin, adopt the way of surgical sutures conduit to be fixed on to the intubate collar extension skin place of patient body.When causing physiology wound and mental anguish to patient, also likely increase patient's infection probability.

The catheter of take again more illustrates effectively fixing meaning of medical catheter as example.Often some patient, due to the needs of self-disease or treatment, need to repose and can not arbitrarily walk about at bed, even can not automatic micturition.For this situation, to restriction patient on one's sick bed, often can use FOLEY catheter as aid, urine or some special postoperative bladder hydrops/blood to be excreted.

FOLEY catheter is generally the flexible hose of being made by silica gel or natural emulsion, comprises two or three coaxial pipelines.A gas tube, a discharging tube and/or a syringe pipe.Wherein there are one or more openings the nearly bladder end of evacuating catheter, and with by intravesical urine, the collection container that body fluid or blood connect by evacuating catheter far-end (such as negative pressure urinal) excretes.Wherein the nearly bladder end of gas tube communicates with an aerating gasbag, far-end is connected with a charge valve, to facilitate medical personnel to be filled with air or liquid (such as normal saline) by air valve in air bag, the air bag expanding can play and prevent that the situation that catheter is surprisingly deviate from by intravesical from occurring.Because the safety and efficacy of FOLEY catheter is verified through clinical application for many years, therefore at present in medical institutions at different levels to applicable patient's extensive use.

But use in the process of FOLEY catheter in reality, patient may need to move or medical personnel need to adjust catheter, change collection container (such as urinal), or carry out the operations such as bladder irrigation, may cause catheter body generation discounting or distortion outside urethral orifice to cause blocking.Also may form tractive to catheter, and then cause body, to urethra or catheter end sacculus, bladder is produced to friction, cause mucous hyperemia, damage, even brings out infection.Therefore the FOLEY catheter body outside urethral orifice is done and effectively fixedly had very important clinical meaning.

The mode of conventional fixedly medical catheter is different types of medical proof fabric.Such as fixing PICC peripheral venous catheter application large-area transparent applies ointment or plaster to increase fixing reliability.Fixedly multiple medical application and the adhesive plaster of venous infusion catheter for another example.Such as the fixing mode of FOLEY catheter comprises, use simple medical proof fabric that body is pasted on the skin of thigh again, or use gauze, binder etc. are wound in body on thigh or bedside support.These simple fixed forms are effectively fixing catheter body both, cannot effectively prevent that again body is particularly along the movement of y direction, nor handled easily.Also have some special-purpose FOLEY catheter fixators to use the structure of glochild hasp stators to be fixed catheter body, such as in US Patent No. 5,941, open in 856.But this patent effectively fixedly catheter body prevent the cost of the movement of y direction be at least partial compression body, and then the impact of (depending on that operator locks skill and the dynamics of bandage) in various degree unobstructed the excreting by body of urine, may cause that patient is uncomfortable, even infect.

Also have some to can be used for the Surgidressing that FOLEY catheter stationary device adopts particular design, such as at US Patent No. D608, open in 887.But this patent adopts, be designed to be fixed on patient's thigh skin by bottom sticker, the second layer sticker by being fixed on bottom sticker by catheter tube be fixed on bottom sticker above.This employing sticker fixedly mode of medical catheter is applied the most widely clinical obtaining.Effectively fixedly body, has also reduced the deformation that the extruding of body is produced simultaneously.But bottom sticker is directly attached on skin may cause allergy, is inconvenient to adjust position, easily accumulates dust antibacterial, remove the skin drawing that sticker produces, fine hair tear fracture causes pain, patient's perspiration etc. reason causes patient worn uncomfortable.

Also have some patients due to the needs for the treatment of, around the Yi Ge position of health, or a plurality of position may need to insert many conduits.Every conduit separately fixing important time, how fixing also particularly important with the orderly arrangement of conduit.At present clinical also not effective device meets this demand.

Therefore need a kind of fixture simple in structure can be common to multiple medical catheter and be fixed on safely and effectively patient, should facilitate medical personnel to adjust the necessary treatment operations such as conduit, patient worn is comfortable simultaneously, avoid irritated, not affecting patient moves on a small quantity, both can short application use, again applicable life-time service.More to be applicable to becoming to produce in batches, material safety, with low cost, be applicable to clinical extensive use.
