Originally be in example, Manual negative pressure source 110 is a syringe-like negative pressure pump being fixed on fixed cap 210, and this syringe-like negative pressure pump specifically comprises syringe 101, push rod 102, piston 103 and two-way air-path interface 104.Wherein this syringe 101 is formed for common housing 540, and depression is embedded in liquid collector 541.Two-way air-path interface 104 also holds with in common housing, and be connected with one end of a two-way pipeline 112, this two-way pipeline 112 other end is connected with air valve 420.
Wherein, when breather check valve 421 only allows to pull out push rod 102, gas enters syringe 101 by this breather check valve 421, and now exhaust check valve 130 is closed, and air cannot be entered in syringe 101 by this exhaust check valve 422.Correspondingly, when inwardly promoting push rod 102, gas is discharged by exhaust check valve 422, and now breather check valve 421 is closed, and air cannot be entered in liquid collector 541 by this breather check valve 421.That is, when pulling out push rod 102, Manual negative pressure source 110 provides negative pressure for liquid collector 541, is aspirated the transudate of patient wound by dressing interface 542 and the dressing covered on patient wound.
Wherein, push rod 102 one end is also provided with and holds component 125.Described component 125 of holding comprises member bodies, and this member bodies surrounds one for palm or can point the perforation 127 passed through, and handled easily person pulls out push rod 102.In the present embodiment, described in hold component 125 with described push rod 102 for removably connecting, wherein, the mode of removably connecting can for being threaded, grafting or buckle connection etc.In other examples, hold component 125 described in can also be formed in one with described push rod 102.Further, the surface of member bodies can be formed for flexible material, as silica gel, EVA, rubber or sponge etc.Further, hold component 125 described in and also can comprise finger recess 126.
The volume of the syringe 101 of the syringe-like negative pressure pump in the present embodiment is 15-50ml, preferably, is 20ml.
In addition, in the present embodiment, also establish a pressure-indication means 150 be connected with liquid collector 541 gas circuit, be used to indicate the pressure in Manual negative pressure source 110.Preferably, this pressure-indication means 150 has the corrugated tube that connecting interface and the other end close for one end, and this connecting interface is connected with liquid collector 541 gas circuit.When pulling out push rod 102, for liquid collector 541 provides negative pressure, now due to pressure-indication means 150, namely corrugated tube is connected with this liquid collector 541, when this corrugated tube is subject to negative pressure, can be compressive state, the negative pressure value in liquid collector 541 can be calculated according to the compressive deformation of corrugated tube and the pressure running parameter of correspondence, shown in Figure 4, the negative pressure value that Manual negative pressure source 110 provides can be indicated accordingly.In addition, corrugated tube directly can also be connected with two-way air-path interface 104 or two-way pipeline 112 by another breather check valve.
In the present embodiment, in fixing hole 543, belt or Portable belt etc. can be penetrated, fixed manual negative pressure equipment 100.
Fig. 4 is the structural representation of a kind of Manual negative pressure therapeutic equipment the 4th embodiment provided by the invention, Manual negative pressure therapeutic equipment 40 shown in Fig. 4 decreases fixed cap 210 on basis embodiment illustrated in fig. 3, but be the increase in graduated tile 545, concrete effect describes in the above-described embodiments all, does not repeat them here.Described push rod 102 one end is also provided with holds component 135.Describedly hold component 135 handled easily person and pull out push rod 102.In the present embodiment, described in hold component 135 with described push rod 102 for removably connecting, wherein, the mode of removably connecting can for being threaded, grafting or buckle connection etc.In other examples, hold component 135 described in can also be formed in one with described push rod 102.Further, the surface of member bodies can be formed for flexible material, as silica gel, EVA, rubber or sponge etc.
Implement the embodiment of the present invention, have following beneficial effect: the Manual negative pressure therapeutic equipment that the embodiment of the present invention provides is provided with holds component, user can manufacture negative pressure by the push-and-pull operation held, and is easy to operation and uses, save muscle power, the treatment of long period can be maintained.
Above disclosedly be only a kind of preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
