Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, embodiment discloses a kind of negative pressure drainage ball for preventing from spilling, and mainly includes drainage ball sheet
Body 1, described 1 one end of drainage ball ontology are equipped with the connector 2 for connecting drainage tube, and the other end is equipped with outlet tube 4, the liquid out
It is equipped the sealing-plug 7 mutually agreed with it at the port of pipe 4, the locking for locking the sealing-plug 7 is provided on outlet tube 4
Escapement.In use, sealing-plug 7 clogs the port of outlet tube 4 and by locking escapement locking, in drainage patient's body
When the body fluid such as blood, diffusate, sealing-plug 7 will not be caused de- because patient body oppresses the fortuitous events such as flow diverter
Out, it avoids drainage-fluid from surprisingly flowing out and causes the pollution of ambient enviroment, influence the measurement and observation of drainage-fluid.
As shown in Figure 1 and Figure 2, the locking escapement is mainly made of screw rod 10, operating block 11 and limited block 12, institute
It states sealing-plug 7 and opens up annular groove 8 by caudal position, the outlet tube 4 opens up inside groove 9, the inside groove 9 by the position of proximal port
Positioned at the inner sidewall of outlet tube 4, the position of inside groove 9 is corresponding with the position of annular groove 8；Run through the company of offering on the outlet tube 4
The tapped through hole of logical inside groove 9, installs screw rod 10 at the tapped through hole, the outer end integrally connected operating block 11 of the screw rod 10,
The inner end integrally connected limited block 12 of screw rod 10, the limited block 12 implement locking for being embedded in the annular groove 8.
In use, sealing-plug 7 is filled in the port of outlet tube 4, rotation process block 11, using screw rod 10 by limited block 12
It is pressed into the annular groove 8 on sealing-plug 7, sealing-plug 7 is locked, avoid artificially squeezing corrugated body 1a and squeeze out sealing-plug 7, lead
Cause leakage.When needing to collect drainage-fluid, then reverse operating operating block 11, makes limited block 12 exit annular groove 8, can extract close
Blocking 7.
In the present embodiment, the size of the limited block 12 is less than the size of inside groove 9, so that limited block 12 can be free
Activity can be simultaneously entirely retracted in inside groove 9, avoid the loading and extraction that influence sealing-plug 7.
As shown in Figure 1, being provided with check valve 3 in the outlet tube 4 in the present embodiment, the check valve 3 is located at sealing-plug
Between 7 and 1 inner cavity of drainage ball ontology, the import of check valve 3 is connected to 1 inner cavity of drainage ball ontology, and the outlet direction of check valve 3 goes out
The port of liquid pipe 4, the check valve 3 only could be opened unidirectionally after the sealing-plug 7 is pulled out from liquid outlet.The check valve
3 preferably use silica gel check valve 3.
The check valve 3 can separate sealing-plug 7 and the drainage-fluid in drainage ball ontology 1, incline under normal circumstances
The when of falling drainage-fluid, pulls out sealing-plug 7 first, because of the reason of check valve 3 is isolated, does not have drainage-fluid on sealing-plug 7, so will not
There is liquid spillage.Then flow diverter is squeezed, drainage-fluid is poured out while opening in check valve 3, after completion, by outlet tube 4
Port and periphery are cleaned out and are sterilized, and sealing-plug 7 is finally covered.
As shown in Figure 1, the left-half of the drainage ball ontology 1 is corrugated body 1a in the present embodiment, right half part is modeling
The left end of Material 1b, the corrugated body 1a and 2 integrally connected of connector, right end and the outlet tube 4 of the plastic body 1b integrally connect
It connects.So set, drainage ball ontology 1 is allowed to stretch, stretching corrugated body 1a can enable drainage ball ontology 1 accommodate collection
More liquid avoid drainage-fluid from polluting even if extracting sealing-plug 7 will not be such that liquid splashes out in the case where liquid full
Surrounding articles, medical staff's skin, work clothes and sheet, the quilt cover of patient etc., to greatly reduce the generation of cross-infection.And
Plastic body 1b can be provided for hand at the support of a grip.
As shown in Figure 1, the outlet tube 4 is equipped with bending section 4a in the present embodiment, so set, extracting sealing-plug 7
When, the drainage-fluid during drainage ball ontology 1 is embedded is moved up by hand strength inertia effects, and the outlet tube 4 with above structure
It can be partially blocked by drainage-fluid, further prevent drainage-fluid to splash out and come.The end of the sealing-plug 7 is arc shape, and close
The length of blocking 7 is less than the length of 4 bending section 4a of outlet tube, can prevent sealing-plug 7 that can not be inserted into outlet tube 4 in this way.
As shown in Figure 1, being arranged fixed ring 5 on the outlet tube 4 in the present embodiment, the sealing-plug 7 passes through connecting band 6
It is connected in fixed ring 5.So set, can prevent sealing-plug 7 from losing, the connecting band 6 preferably uses elastic webbing, connects in this way
Tape splicing 6 can stretch, and avoid overexertion when drawing sealing-plug 7 and involve drainage ball.
Described above is only the preferred embodiment of the utility model, and above-mentioned specific embodiment is not to the utility model
Limitation.In the technical idea scope of the utility model, various modifications and modification, the ordinary skill of all this fields can occur
Retouching, modification or the equivalent replacement that personnel are made as described above belong to the range that the utility model is protected.
