Fig. 1 shows the sketch map of Wound processing device in the present embodiment; Fig. 2 shows that Wound processing device in the present embodiment is connected to the sketch map of a wound; Fig. 3 A shows a variant of elastic component in the Wound processing device; Fig. 3 B shows another variant of elastic component in the Wound processing device.Referring to Fig. 1 and Fig. 2, Wound processing device 10 is connected in a wound W (as shown in Figure 2), and the waste liquid F that is used for wound W is produced derives, and Wound processing device 10 comprises a drainage unit 110 and a negative pressure liquid collecting module.More detailed, Wound processing device 10 comprises a drainage unit 110, a linkage unit 130, a negative pressure source 150, a liquid collector 170 and a pressure transducer 190.
In the present embodiment, drainage unit 110 comprises a main body 111, two elastic components 113 and four accommodation sections 115.Main body 111 has one first end 1101 and one second end 1102; First end 1101 is connected to wound W; And patch, soft sucker are sealed in the part utilization and the bio-compatibility porous material forms confined space (as shown in Figure 2) being connected with wound W, and second end 1102 is communicated with the negative pressure liquid collector through linkage unit 130.
Cooperation it should be noted that referring to Fig. 3 A, 3B in the present embodiment, elastic component 113 is two, but is not limited thereto, and elastic component 113 can be one or a plurality of optionally.And the T of tooth portion of elastic component 113 is arc in the present embodiment, but can also be triangular in shape shown in Fig. 3 A, the rectangle shown in Fig. 3 B or other shape.And the quantity of the T of tooth portion is also unrestricted, but in order between the T of tooth portion, to form at least one accommodation section 115, the quantity of the T of tooth portion is generally more than two.
Please get back to Fig. 1; Linkage unit 130 connects drainage unit 110 and negative pressure liquid collecting module; And comprise one first pipeline T1 and two second pipeline T2; The first pipeline T1 is communicated with second end 1102 and the negative pressure liquid collecting module of drainage unit 110; Two second pipeline T2 then are communicated with two elastic components 113 and the first pipeline T1 respectively, wherein utilize dog leg piping with two second pipeline T2 junctions flow resistance structure R being set respectively at the first pipeline T1, and pressure transducer 190 are to be connected with one of them second pipeline T2 arbitrarily.
It should be noted; Linkage unit 130 comprises that two second pipeline T2 are communicated with two elastic components 113 respectively in this embodiment; That is to say; The quantity of the second pipeline T2 is to be provided with for the quantity that cooperates elastic component 113, and when being a plurality of as if elastic component 113, the second pipeline T2 is a plurality of corresponding to elastic component 113 then.
Negative pressure liquid collecting module is to connect with drainage unit 110.Negative pressure liquid collecting module comprises negative pressure source 150 and liquid collector 170, and wherein negative pressure source 150 provides negative pressure, and liquid collector 170 is to collect the waste liquid of being drawn by wound W.In the present embodiment; Negative pressure source 150 is arranged between linkage unit 130 and the liquid collector 170, detailed explanation, and negative pressure source 150 is to be arranged on the first pipeline T1; And through linkage unit 130 and being connected with drainage unit 110; 150 pairs of drainage units 110 of negative pressure source are bled (negative pressure source 150 provides negative pressure) and wound W are provided the environment of a negative pressure, and when bleeding, the waste liquid F at wound W place are transported to liquid collector 170, keep the cleaning of wound W.Yet in another embodiment of the present invention, negative pressure liquid collecting module also can see through liquid collector 170 and be communicated with drainage unit 110, and meaning is that liquid collector 170 is arranged between linkage unit 130 and the negative pressure source 150.Detailed explanation, liquid collector 170 are to be arranged on the first pipeline T1, and are connected with drainage unit 110 through linkage unit 130.
Fig. 4 A shows the sketch map when elastic component is out of shape in the drainage set in the present embodiment.Simultaneously referring to Fig. 1 and Fig. 4 A; During operation Wound processing device 10; Open negative pressure source 150 so that drainage unit 110 is bled, this moment, negative pressure source 150 was bled to elastic component 113 through the second pipeline T2, was present in air in elastic component 113 holes by sucking-off; Elastic component 113 is compressed and is out of shape; Negative pressure source 150 after elastic component 113 distortion accommodation section 115 communicated with each other, and first end 1101 is communicated with second end 1102, just and can be pumped waste liquid F to second end 1102 by first end 1101 through the first pipeline T1 and is collected into liquid collector 170 (shown in arrow among Fig. 4 A) through the accommodation section 115 that communicates with each other.
Sketch map after the elastic component distortion in the drainage set in Fig. 4 B demonstration present embodiment.Referring to Fig. 4 B, when negative pressure source 150 loses heart (negative pressure source 150 shuts down), elastic component 113 reinstatements; Accommodation section 115 is isolated again each other, and when accommodation section 115 is isolated from each other, also first end 1101 and second end 1102 are isolated; At this moment; Waste liquid F is clamped by elastic component 113, rests in the accommodation section 115 of carrying in the way, can't be back to that first end 1101 contacts with wound W once more and situation that secondary pollution takes place.
Fig. 5 A and 5B show the sketch map of linkage unit in the present embodiment.Referring to Fig. 5 A; Because the first pipeline T1 and the second pipeline T2 are interconnected; So the force value in all passages is identical; When negative pressure source 150 is bled (airflow direction is shown in arrow among Fig. 5 A), the first pipeline T1 is communicated with wound W, can directly detect the pressure at wound W place through the pressure detection device 190 that is connected in the second pipeline T2.Referring to Fig. 5 B; When negative pressure source 150 loses heart (airflow direction is shown in arrow among Fig. 5 B); Little air refluxes among the first pipeline T1 and the second pipeline T2; But the waste liquid F among the first pipeline T1 is stopped by flow resistance structure R, can't flow among the second pipeline T2, and the elastic component 113 that therefore is connected with the second pipeline T2 also can not have any possibility that contacts with waste liquid F with pressure detection device 190.
The elastic component 113 that drainage unit 110 in the Wound processing device 10 of the present invention is included;, negative pressure source 150 can prevent that waste liquid F from flowing back to the infection that wound W place causes wound W when losing heart; And the included flow resistance structure R of linkage unit 130 in the Wound processing device 10, the pressure detection device 190 that can avoid being connected with linkage unit 130 contacts with waste liquid F and causes damage.
Though the present invention discloses as above with all embodiment; Right its is not in order to restriction the present invention; Any personnel that are familiar with this technology; Do not breaking away from the spirit and scope of the present invention, changing and retouching, so protection scope of the present invention is as the criterion when looking the scope that the accompanying Claim book defined when doing.
