Abstract
The utility model relates to a medical device, particularly a closed negative pressure suction water sealing bottle for the drainage of a thoracic and abdominal cavity. The utility model mainly comprises a liquid loading bottle, a water sealing pressure regulating bottle and a plurality of inlet and outlet connecting tubes. The utility model is characterized in that a linked control body with a water sealing tube is connected between the two bottles, the negative pressure channel of the whole device is communicated by the linked control body so that the water sealing liquid can be effectively prevented from flowing backwards and manual suction can be performed by the self regulation of negative pressure. The utility model overcomes the disadvantage that the water sealing liquid back flow preventing effect of the product existing in the prior art is poor. The utility model is a safe, practical and closed negative pressure suction water sealing bottle.
Description
This utility model relates to a kind of medical apparatus and instruments, the vacuum suction water-sealed drainage bottle that particularly being applicable to needs closed drainage after spontaneous pneumothorax, traumatic pneumothorax, hemothorax, empyema, tumor and splanchnocoel are performed the operation patient is used.
The present vacuum suction water-sealed drainage bottle that uses, being essentially two bottle of three Room is that diversion chamber, water tight compartment and negative pressure are adjusted the structure that the chamber is formed, there is the vacuum suction pipe to be connected and to have water sealing (sealing water) pipe between diversion chamber and the water tight compartment, negative pressure is adjusted the chamber has the one one open to atmosphere negative pressure adjustable pipe of end to insert in the water sealing liquid, also have an outer suction pump to take over, water tight compartment communicates with the air chamber that negative pressure is adjusted the chamber, in order to prevent that the water sealing liquid in the water tight compartment from pouring in down a chimney to diversion chamber, generally can be on the vacuum suction pipe between diversion chamber and the water tight compartment check valve of adjunction.In actual use, the reasons such as influence owing to the quality differential pressure of valve make check valve not control water sealing liquid fully and pour in down a chimney, and will influence the degree of accuracy of drain metering like this and cause artificial pneumothorax.
The purpose of this utility model is to solve the existing water-sealed drainage bottle controlling liquid phenomenon of pouring in down a chimney fully, and a kind of safety and enclosed vacuum suction water-sealed drainage bottle that can self adjusting negative pressure are provided.
This utility model is made up of hydrops bottle, water seal adjust blood pressure bottle, connect to advance the drainage tube in thoracic cavity on the hydrops bottle and connecing post, have a upper end to communicate with atmosphere on the water seal adjust blood pressure bottle, the negative pressure adjustable pipe at the bottom of the lower end is inserted into bottle also has a suction catheter that links to each other with outer suction pump to connect post; The joint control body that the root water sealing (sealing water) pipe of ining succession is arranged between hydrops bottle and water seal adjust blood pressure bottle, its upper end have a communicating pipe that connects the hydrops bottle, and the water sealing (sealing water) pipe of its lower end is inserted in the water seal adjust blood pressure bottle, plays water seal and prevents the effect that water sealing liquid pours in down a chimney.
Adopt the enclosed vacuum suction water-sealed drainage bottle of band joint control body, because the diameter of its upper and lower two pipes of relative aperture of joint control body is much bigger, when if pressure changes the liquid make in the water sealing (sealing water) pipe and rises to the joint control body in the use, can produce bigger water seal face, and the connection mouth of pipe and this water seal face have certain distance, prevent that effectively water sealing liquid from pouring in down a chimney phenomenon in guaranteeing to use.In addition, can will close communicating pipe on one side during use, with hands push joint control body to water seal adjust blood pressure bottle aerofluxus on one side, repeatedly repeat, manually attract.
Fig. 1 is this utility model structural representation.
Be described further below in conjunction with drawings and Examples: as shown in Figure 1, this utility model mainly comprises hydrops bottle 1, water seal adjust blood pressure bottle 7 and some turnover pipes connect post and connection tube, between these two bottles, be connected with the joint control body 4 of a band water sealing (sealing water) pipe 10, link up the negative pressure channel of whole device, its operation principle is that the pressure differential of utilizing vacuum suction water-sealed drainage bottle and human body splanchnocoel to ask is carried out closed drainage.Bottle in this device can be used the disposable moulded section of pvc material, and two bottles can be connected as a single entity, and also can separate molding, and the joint control body is molding separately then.Available dividing plate is divided into three lattice in the hydrops bottle 1, and a bottle wall is marked with scale, is convenient to metering, observes the drain result, and on the bottle two connect the post two tubes of ining succession, and one is the drainage tube 2 that enters torso model, and another root is the communicating pipe 3 of connection joint control body 4; Water seal adjust blood pressure bottle 7 is connected with three pipes, one communicate with atmosphere for the upper end, the lower end inserts the surge pipe 5 in the water sealing liquid, it can just be regulated pressure according to the liquid level in the adjust blood pressure bottle and change, another root is the suction catheter 6 that joins with outer suction pump, can select for use as required, also having one is the water sealing (sealing water) pipe 10 of joint control body 4 lower ends; Joint control body 4 plays the connection control action at hydrops bottle 1 and 7 in water seal adjust blood pressure bottle, it can be between two bottles, also can place their top, but generally to be higher than more than the water seal liquid level, joint control body 4 upper ends have communicating pipe 3 to lead to hydrops bottle 1, the water sealing (sealing water) pipe 10 of lower end is inserted in the interior water sealing liquid of adjust blood pressure bottle, generally makes water sealing liquid with normal saline.Be marked with scale at joint control body 4 and water sealing (sealing water) pipe 10,, can recognize the intravital negative pressure value of patient, be convenient to timely adjustment along with the lifting of liquid level in the water sealing (sealing water) pipe.A dividing plate 9 is arranged in the water seal adjust blood pressure bottle, bottle is divided into top communicates, the bottom is divided into water tight compartment 11 and surge-chamber 8, the liquid level of surge-chamber 8 is than water tight compartment 11 liquid level height.Joint control body 4 can be made with materials such as flexible PVC material or rubber, when needs increase hydrops bottle negative pressure, can close on the other hand communicating pipe 3, push joint control body 4 on the other hand, make air wherein press to the adjust blood pressure bottle by water sealing (sealing water) pipe, two cooperate repeated several times, can manually attract.
