Detailed description of the invention
Comprise according to the connecting sucker for negative pressure drainage of the present disclosure: chassis, described chassis has central opening; Pillar, described pillar to be arranged on described chassis and to have the inner space be communicated with the central opening on described chassis; First pipe joint, described first pipe joint to be arranged on described pillar and to be communicated with the inner space of described pillar; Second pipe interface, described second pipe interface to be arranged on described pillar and to be communicated with the inner space of described pillar; And lid, described lid is for sealing described first pipe joint.
According to the disclosure, the position being arranged on pillar for described first pipe joint and described second pipe interface does not limit.Such as, described first pipe joint and described second pipe interface can be arranged on not homonymy or the same side of pillar.Preferably, described first pipe joint and described second pipe interface are arranged on the same side of described pillar abreast.
Fig. 1 shows the unitary construction of the connecting sucker for negative pressure drainage according to some embodiment of the present disclosure.As shown in Figure 1, the connecting sucker 100 for negative pressure drainage comprises: chassis 101; Pillar 102, described pillar 102 is arranged on described chassis 101; First pipe joint 103, described first pipe joint 103 is arranged on described pillar 102; Second pipe interface 104, described second pipe interface 104 and described first pipe joint 103 are arranged on the same side of described pillar 102 abreast; With lid 105, described lid 105 is for sealing described first pipe joint 103.
Fig. 2 shows the basal surface on the chassis of the connecting sucker for negative pressure drainage according to some embodiment of the present disclosure.As shown in Figure 2, chassis 101 has central opening 1011.
In addition, as shown in Figure 2, preferred described chassis 101 is provided with the groove 1012 that multiple radial direction extends to described opening 1011 on its bottom surface.This groove is directly relative with wound dressing, negative pressure can be evenly distributed on wound dressing, be conducive to wound dressing to central reduction.
Fig. 3 shows the internal structure of the connecting sucker for negative pressure drainage according to some embodiment of the present disclosure.As shown in Figure 3, described pillar 102 has inner space 1021, this inner space 1021 is communicated with the central opening 1011 on chassis 101, and is communicated with second pipe interface 104 with the first pipe joint 103, and described lid 105 is arranged on the seam of the first pipe joint 103.
In order to the intensity effectively increasing connecting sucker inhales flat ability to strengthen its opposing negative pressure, described connecting sucker can also comprise at least one reinforcement 106 on the surface being arranged on described pillar, as shown in Figure 4.
In order to verify reinforcement can effectively increase connecting sucker intensity and strengthen its opposing negative pressure inhale flat ability, carried out simulation analysis of computer.Simulation result shows, when without reinforcement, the elastic modelling quantity of connecting sucker is 3.55MPa, and when arranging reinforcement, the elastic modelling quantity of connecting sucker is 3.79MPa, adds 6.3%.This shows, under the prerequisite of satisfied opposing negative pressure deformation requirements, increasing reinforcement makes the hardness number needed for overall raw material of connecting sucker diminish, and this can make the chassis of connecting sucker more soft, thus increases comfort and compliance on irregular surfaces.
Fig. 5 and Fig. 6 respectively illustrates two kinds of application modes of the connecting sucker for negative pressure drainage according to some embodiment of the present disclosure.Such as, according to connecting sucker of the present disclosure can with hospital existing usual pressure control valve with the use of.When this application mode, as shown in Figure 5, first pipe joint lid of connecting sucker 100 is blocked, and the second pipe interface of connecting sucker 100 is connected with the pipeline 1 being connected to negative pressure source (not shown), and the chassis of connecting sucker 100 contacts with wound dressing.According to connecting sucker of the present disclosure also can with suction pump or draft regulator (such as, can purchased from the suction pump of 3M company or draft regulator) with the use of make its can the negative pressure value size of Real-Time Monitoring wound site to avoid the risk of negative pressure.The vacuum suction pump of described 3M company comprises source of negative pressure (pump), the control panel being with pressure transducer and power module etc.This draft regulator comprises the control panel, power module etc. of electromagnetic valve, band B/P EGR Back Pressure Transducer EGR.One end of draft regulator is connected on the wall pump of hospital, thus provides negative pressure source.When this application mode, as shown in Figure 6, first pipe joint of connecting sucker 100 blocks up without cap seal, but be connected with the pipeline 2 of the pressure transducer (not shown) being connected to this vacuum suction pump or draft regulator, negative pressure value on described pressure transducer energy Real-Time Monitoring wound, and feed back to this vacuum suction pump or draft regulator, in addition, the second pipe interface of connecting sucker 100 is connected with the pipeline 1 being connected to negative pressure source (not shown), and the chassis of connecting sucker 100 contacts with wound dressing.Gather negative pressure numerical value by described pressure transducer and carried out regulating and controlling the opening and closing of negative pressure pump or electromagnetic valve by control panel, and then reaching the function making wound end negative pressure numerical stability in setting value.
Soft materials can be used as thermoplastic elastomer (TPE) according to the connecting sucker for negative pressure drainage of the present disclosure, silicone rubber or polrvinyl chloride by known method as injection moulding or compression moulding preparation.Said method integrated molding can be passed through according to the connecting sucker for negative pressure drainage of the present disclosure.
Although for illustrational object, above-mentioned detailed description of the invention comprises many details, and those of ordinary skill in the art should be understood that many modification of these details, change, substitute and change within the scope of the disclosure all protected in claim.Therefore, the disclosure that the disclosure described in detailed description of the invention is not protected claim applies any restriction.Proper range of the present disclosure should be limited by claims and suitable legal equivalents thereof.The list of references of all references is incorporated herein all by reference in full.
