Abstract
The utility model relates to a three-cavity single saccule valve dilation catheter which is characterized in that a four-way connecting head is positioned on the proximal end of the three-cavity single saccule valve dilation catheter and is connected with an inner and an outer catheters. A four-way connecting pipe is provided with a blood pressure measurement cavity. The far end of the blood pressure measurement cavity is positioned on the position of 15 to 65 mm away from the far end of a saccule. An end mouth is communicated with the outer surface of the outer catheter. The proximal end of the end mouth is positioned in the four-way connecting head and can be directly connected with an instrument. The utility model relieves the puncture of the femoral artery and the insertion of the pigtail catheter of a patient, reduces the pain of the patient, reduces the economic burden of the patient, reduces the time of an operation and reduces the X ray radiation dosage of a doctor and the patient.
Description
This utility model relates to a kind of three chamber single saccule valve dilating catheters.
Used valve sacculus dilating catheter all is a double channel catheter, mainly is to be used to carry out percutaneous puncture sacculus valvoplasty.Operation process need be measured the valve transvalvular pressure gradient, with the assessment therapeutic effect; The pigtail catheter that pressure reduction normally utilizes foley's tube and femoral artery puncture to send into is measured synchronously, or utilizes the foley's tube far distance port at different position finding pressure, gets pressure gradient through computing again.For example, percutaneous balloon mitral valvuloplasty can puncture by right femoral artery when carrying out Bicuspid valve transvalvular pressure gradient mensuration, and pigtail catheter is delivered to left ventricle, measures synchronously with the foley's tube at left atrium again; Or the diastole end that utilizes the foley's tube far distance port to measure the mean pressure of left atrium and left ventricle respectively presses, and both subtract each other and obtain the Bicuspid valve pressure gradient.All there is its shortcoming in these two kinds of methods, though said method one is measured the accuracy height, and can measure synchronously, the patient damaged greatly, and bleeding stopping period long (needing compressing 20～30 minutes), and increase patient economy burden.In addition, also increase operating time and increased doctor and patient's X-ray radiation dose.Though said method two does not increase damage to the patient, can not measure pressure gradient synchronously, and the mensuration of carrying out different parts pressure increased operating difficulty and operating time equally, and doctor and patient's X-ray irradiation dose.
The purpose of this utility model is to provide a kind of three chamber single saccule valve dilating catheters that can measure the valve transvalvular pressure gradient synchronously, reduce patient suffering and financial burden.
This utility model is to realize like this, this product mainly is made up of sacculus, outer catheter, inner catheter and four-way connection, sacculus is positioned at the distal-most end of conduit, and its head, afterbody are connected with inside and outside conduit respectively, and four-way connection is positioned at the near-end of conduit, it also is connected with inside and outside conduit, four-way connection is provided with a pressure measuring cavity, and the end of its tube chamber is positioned at from sacculus far-end 15～65mm place, and port passes to the outer catheter outer surface, near-end then is positioned at four-way connection, can directly be connected with instrument.This pressure measuring cavity can be located on the tube wall of outer catheter, the far-end mouth of directly beginning to speak, or be located in the inner chamber of outer catheter, its far distance port mouth that engages and begin to speak with outer catheter.
Below in conjunction with drawings and Examples this utility model is described in detail.
Fig. 1 is located at the structural representation on the tube wall of outer catheter for the pressure measuring cavity of this utility model.
Fig. 2 is that the pressure measuring cavity of this utility model is located at the structural representation in the outer catheter inner chamber.
Fig. 3 measures the sketch map of Bicuspid valve transvalvular pressure gradient synchronously for this utility model.
Description of drawings: 1-sacculus 2-outer catheter 3-inner catheter 4-pressure measuring cavity proximal port 5-pressure measuring cavity far distance port 6-distal end of catheter mouth 7-four-way connection 8-left ventricle 9-left atrium 10-right atrium 11-right ventricle
This utility model mainly is made up of with four-way connection (7) sacculus (1), outer catheter (2), inner catheter (3), and sacculus (1) is positioned at the distal-most end of conduit, and its head, afterbody are connected with inside and outside conduit (3), (2) respectively; Four-way connection (7) is positioned at the near-end of conduit, its also with inside and outside conduit (3), (2), four-way connection (7) is provided with a pressure measuring cavity, the far-end of its tube chamber is positioned at from sacculus far-end 15～65mm, port (5) passes to outer catheter (2) outer surface, near-end then is positioned at four-way connection, can directly be connected with instrument.This pressure measuring cavity can be located on the tube wall of outer catheter (2), the direct atrium of far-end, or be located in the inner chamber of outer catheter (2), its far distance port and outer catheter (2) mouth that engages and begin to speak.
During the operation pressure measurement,, can measure transvalvular pressure gradient synchronously as long as pressure measuring cavity and distal end of catheter tube chamber are connected on the instrument.
The advantage of the utility model: (1) is removed the patient from and is carried out femoral artery puncture and slotting pigtail catheter, Reduce patient suffering and financial burden. (2) avoid repeatedly allowing sacculus carry out pressure measurement by valve orifice, Thereby minimizing operating time and doctor and patient's X-ray dose of radiation.
Claims (2)
1. chamber single saccule valve dilating catheter, it is made up of sacculus, outer catheter, inner catheter and four-way connection, and sacculus is positioned at the distal-most end of conduit, and its head, afterbody are connected with inside and outside conduit respectively; It is characterized in that four-way connection is positioned at the near-end of conduit, it also is connected with inside and outside conduit, and four-way connection is provided with a pressure measuring cavity, the far-end of pressure measurement tube chamber is positioned at from sacculus far-end 15～65mm place, port passes to the outer catheter outer surface, and near-end then is positioned at four-way connection, can directly be connected with instrument.
2. three chamber single saccule valve dilating catheters according to claim 1 is characterized in that pressure measuring cavity can be located on the tube wall of outer catheter, the far-end mouth of directly beginning to speak, or be located in the inner chamber of outer catheter, its far distance port mouth that engages and begin to speak with outer catheter.
