Description
Technical field
The present invention relates to the mating equipment technology fields of Medical Devices urodynamics test, especially a kind of disposable straight
Intestines manometric saccule catheter.
Background technology
Urodynamics is a subdiscipline of urinary surgery, relies primarily on hydrodynamics and electrophysiological basic
Principle and method, each portion's pressure of detection urinary tract, flow rate and bioelectric, to understand function, the mechanism of urinary tract dispatch urine
And the Pathological Physiology variation of urinary dysfunction disease.In routine inspection project, using manometry in rectum foley's tube
It is essential equipment to be measured to rectal pressure, medically, generally utilizes fluid path connecting tube by urodynamic analysis instrument
On pressure sensor be connected with manometry in rectum foley's tube, using connection fluid pressure equal principle everywhere, carry out rectum
The transmission and measurement of pressure.
Now with technology in, the product using water as pressure transmission medium, but it is difficult emptying often occur, needs to spend
Plenty of time；Air enters because other operations also tend to bring air into pressure transmission medium water after excluding, and portioned product
It is opaque that operator is caused not see or have not focused on that this operation is brought air into and entered in water.Main body tube section simultaneously
For circle, uncontrolled certain angle can be rotated in insertion process, the sacculus being sleeved on main body tube can be with main body tube
Turn an angle even serious kink, so as to cause to transmit pressure and actually have deviation larger or even no pressure.
It in clinical manipulation, needs to reach in whole transfer medium and generally requires to take much time without visible bubble in bubble, influence to check efficiency.
Therefore many operators are the saving time to have ignored wherein bubble or have not focused on the bubble of operating process generation, to
Influence the accuracy of inspection result.
Existing technical literature ZL200720082123.X discloses a kind of rectal pressure measurement conduit, the rectal pressure measurement conduit due to
Structure problem causes the gas of inlet end that cannot exclude completely, needs slowly to adjust the angle very much, and the bubble of convergence is connecing very much
It is possible to exclude when proximal aperture.Actual use process, this operation waste a large amount of time, influence detection efficiency, especially
Bubble is still can not rule out wasting a large amount of time for just contacting operator not.

Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to following institute
It states.
As Figure 1 and Figure 4, a kind of disposable manometry in rectum foley's tube, it includes connector A1, connector B2, water inlet
Connecting tube 3, water outlet connecting tube 4, protection cap 5, main body tube 6, sacculus 7, transfer tube A8 and transfer tube B9.
As shown in Figure 1, Figure 2 and shown in Fig. 4, the connector A1 is band two pass joint of valve, such as spiral valve arrangement, ball valve knot
Structure, interference structure, check configuration, electromagnetic valve structure etc., and with water inlet connecting tube 3 one end be connected, intake connecting tube 3 it is another
End is connected by transfer tube A8 with the cavity A10 in main body tube 6.
As shown in Figure 1, Figure 2 and shown in Fig. 4, the connector B2 is valve tee connector, such as spiral valve arrangement, ball valve knot
Structure, interference structure, check configuration, electromagnetic valve structure etc., and be connected with one end of water outlet connecting tube 4, it is discharged the another of connecting tube 4
End is connected by transfer tube B9 with cavity B11, the cavity C12 in main body tube 6, and the cavity B11 and cavity C12 of main body tube exist
It is penetrated through at the position being connect with transfer tube B9 and forms cavity D13.
As shown in Figure 1, Figure 2, shown in Fig. 4 and Fig. 5, the transfer tube A8 and transfer tube B9 are arranged in protective case 5, are hard
The single lumen catheter of material and respectively with water inlet connecting tube 3, water outlet connecting tube 4 and main body tube 6 be interference fitted, the inner cavity of transfer tube A8
Area of section is identical as intake antrum area of section, the sum of the area of section of the inner cavity of transfer tube B9 and water chamber area of section phase
Together
As shown in figure 3, the leading portion of the main body tube 6 is coated by sacculus 7, there are hole B15, main body tube 6 and ball at tip in this section
The bottommost that capsule 7 contacts has hole A14, and hole C16, mesoporous C16 and main body are provided on the main body tube 6 between hole A14 and hole B15
The cavity A121 of pipe 6 is connected, and hole A14, hole B15 are connected with cavity C12 and chamber B11 respectively.
The course of work of the present invention is as follows：It checks that all channels of connector A1 and connector B2 are in open state, will fill
The syringe of water is connected with connector A1, and connector B2 is directed at waste collecting device, which is used to collect extra give up
Liquid.Starting water filling, water is full of the cavity A10 in connector A1, water inlet pipe connected pipe 3, transfer tube A8, main body tube 6 successively at this time, and
Entered in sacculus by hole C16.
According to " bernoulli principle ", " law of conservation of energy " and " gravity ", when sacculus end upward when, by hole C16 into
Bottom, fraction water access aperture A14 can be preferentially full of by entering the water of sacculus, and another part water rises for liquid level and eventually enters into hole
B15；When sacculus end downward when, the water that chamber is entered by hole C16 can be preferentially full of at the top of sacculus, and fraction water access aperture B15 is another
Part water rises for liquid level and eventually enters into hole C16.Aforementioned two kinds of situations, water can conveniently be full of sacculus, that is, exclude sacculus
In air.
Water through hole A14, hole B15 in sacculus enter cavity C12 and cavity B11 and converge at cavity D13, and pass through
Transfer tube B11 enters in water outlet connecting tube 4, finally by the exclusion of connector B2 and entrance waste collecting device.
After the gas in cavity is excluded, the valve of connector A1 is closed, and the end E17 of connector B2 is connect with fluid path
Pipe presses sacculus and excludes extra water at this time, and the water in sacculus can be excluded by the end F18 of connector B2 and take away connector 2 at this time
The gas generated when being connect with fluid path connecting tube.The valve end E17 finally adjusted in connector B2 is communicated and is held with water outlet connecting tube 4
F18 is obstructed.
6 sacculus section of main body tube is inserted into patient's rectum in the case where not rotating to prescribed depth, elliptical cross-sectional shape
Operator can be reminded to set whether pipe process has rotation phenomenon.
The conduit can conveniently in pressure release transfer medium water air, operation is simpler, while can guarantee most
Without visible bubble in bubble in medium water afterwards, the accuracy for checking efficiency and inspection result is improved, main body tube elliptical cross-sectional shape
Design can prevent from setting the rotation of pipe process and the gross distortion that leads to sacculus, and catheterization procedure can be greatly reduced in the round and smooth design at tip
The foreign body sensation of patient and the pain of patient.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, under the premise of different disengaging the invention are conceived, various modifications and improvements can be made, these belong to this hair
Bright protection domain.
