Description
Technical field
This utility model relates to technical field of medical instruments, in particular to a kind of abdominocentesis drainage device.
Background technology
Peritoneocentesis is the Clinics directly thrusting peritoneal cavity by puncture needle from abdomen antetheca.One of its effect is appropriate extraction ascites, to alleviate the Intraabdominal pressure of patient, alleviates abdominal distention, uncomfortable in chest, out of breath, the symptoms such as dyspnea, reduces venous return resistance, improve blood circulation.
The enforcement of peritoneocentesis generally adopts common disposable syringe, but medical implementer is when using common disposable syringe, and a hands needs fixed needle, and another hands need extract ascites, so, not only operates inconvenience, and operation effort.If the ascites volume of patient is large, medical implementer also needs to change syringe, causes the workload of medical implementer to increase, the reduction of medical efficiency.
Summary of the invention
The technical problem that this utility model solves: medical implementer adopts common disposable syringe to implement peritoneocentesis, not only operate inconvenience, and operation effort, especially when patient exists a large amount of ascites, medical treatment implementer needs to change syringe, makes operating procedure more loaded down with trivial details.
This utility model provides following technical scheme: a kind of abdominocentesis drainage device, comprise puncture needle, rubber linking tube, switch, negative pressure sacculus, described puncture needle and rubber linking tube one end are tightly connected, the other end and the negative pressure sacculus of described rubber linking tube are tightly connected, and described switch-linear hybrid is on rubber linking tube; Described negative pressure sacculus top is provided with circular conic protruding portions, described circular conic protruding portions is provided with through hole, described through hole and negative pressure sacculus inner space, described circular conic protruding portions and rubber linking tube are tightly connected, liquid outlet is offered bottom described negative pressure sacculus, described liquid outlet is provided with seal cover, and described seal cover is hinged on bottom negative pressure sacculus.
By technique scheme, because rubber linking tube one end and puncture needle are tightly connected, the other end and negative pressure sacculus are tightly connected, so whole abdominocentesis drainage device only has puncture needle to be in communication with the outside.Implementer is before carrying out peritoneocentesis in medical treatment, extruding negative pressure sacculus, and makes switch be in closure state, and so, negative pressure sacculus is negative pressure state.Afterwards, medical implementer carries out peritoneocentesis, and puncture needle is thrust abdominal cavity of patients, and open switch, now, the abdominal cavity of patient is communicated with negative pressure sacculus with rubber linking tube by puncture needle, and the negative pressure sacculus in negative pressure state utilizes negative-pressure siphon principle automatic suction ascites.Further illustrate as of the present utility model, circular conic protruding portions can facilitate rubber linking tube and negative pressure sacculus to be tightly connected, and liquid outlet and seal cover facilitate the liquid in negative pressure sacculus to arrange outward.When seal cover covers on liquid outlet, seal cover should seal liquid outlet, otherwise negative pressure sacculus is difficult to form negative pressure state.
Pass through technique scheme, the medical implementer carrying out peritoneocentesis only needs hand-held puncture needle to puncture, afterwards, negative pressure sacculus and auto-pumping ascites, so, make peritoneocentesis easy and simple to handle, even if patient exists a large amount of ascites, medical treatment implementer also without the need to changing abdominal paracentesis apparatus, is conducive to the raising of medical efficiency in the process of carrying out peritoneocentesis.
Further illustrate as of the present utility model, described puncture needle comprises syringe needle, pintle, the pin wing, and described puncture needle is tightly connected by pintle and rubber linking tube one end.The hand-holdable pin wing of implementer of peritoneocentesis punctures, and therefore, the existence of the pin wing can facilitate implementer to carry out peritoneocentesis.
Further illustrate as of the present utility model, described switch-linear hybrid is in the middle position of rubber linking tube length direction.The length of described rubber linking tube is 12cm, and the external diameter of described rubber linking tube is 6cm.Switch variety is not limit herein, as long as can control the break-make of rubber linking tube, namely uses clip also can.
As to further improvement of the utility model, described negative pressure sacculus is transparent, and described negative pressure sacculus outer wall is provided with containing mark.Design like this, medical implementer and patient all can clearly know abdominocentesis drainage device extract the amount of abdomen liquid.As further illustrating negative pressure sacculus, the material of described negative pressure sacculus is polyester or Low Density Polyethylene.The negative pressure sacculus that polyester or Low Density Polyethylene make can extrude, and makes negative pressure sacculus be in negative pressure state.
