Abstract
The utility model relates to a disposable medical therapeutic implement, which can be used for cancer sampling, suction focus body fluid and the irrigation of injection type. The disposable medical therapeutic implement mainly solves the problems that the existing injection syringe can not be operated by one person completely and can cause infection easily, and the labour intensity is big. The utility model is characterized in that the back end of a suction barrel is fixed to a sleeve barrel with a slide groove; a piston rod is arranged and matched between the suction barrel and the sleeve barrel; a groove is arranged on the sleeve barrel; a multichannel connector is arranged between the suction barrel and a needle head; the connector is connected with an apocenosis bag; the needle head is provided with a fixer with needle insertion depth. The utility model is disposable, can be operated by one person, and has the advantages of low labour intensity, low cost, good effect, etc.
Description
This utility model relates to a kind of syringe, and particularly a kind of sampling that both can be used for carcinoma can be used for aspirating the disposable multifunction injection medical treatment device of ascites pleural fluid, cyst, hydrops and flushing abscess again.
At present, mostly adopt conventional injector to carry out the sampling of carcinoma, suction ascites pleural fluid, cyst, hydrops and flushing abscess.Its weak point is to need two people to operate simultaneously just can finish above-mentioned work, and labor intensity is big, and inefficiency particularly in operation because of negative pressure in the body can't clean up focus, is changed syringe needle and syringe in addition again and again, easily causes pneumothorax and infection.For this reason, the ZL93205794.2 Chinese patent has proposed this way of negative pressure booster, promptly on common syringe, increase the handle of the power-assisted of a metal, can realize the one man operation, but because of it is a metallic article, weak point is that cost is too high, can not become the Dispoable medical apparatus, sterilization is used and will be brought a series of problem to user and patient repeatedly, and its device is not provided with negative pressure lock and depth of needle holder in addition, still can not reach the purpose of people's one-handed performance fully.
The purpose of this utility model is exactly to provide a kind of sampling of carcinoma of can being undertaken by the one man operation fully at above-mentioned weak point, suction ascites pleural fluid, cyst, hydrops and flushing abscess, operation easily, conveniently, to the focus thorough treatment, and be the low disposable multifunction medical treatment device of all plastic product, cost.
Technical solution of the present utility model is: a kind of disposable multifunction medical treatment device, comprise suction tube, piston rod and syringe needle, and it is characterized in that: fix the sleeve that its both sides are provided with chute in described suction tube rear end.Piston rod is positioned among suction tube and the sleeve and cooperates with it.Sleeve is provided with the groove of lockable piston rod.Be provided with many logical adapters between the nipple of suction tube and the syringe needle, these many logical adapters are connected with an apocenosis bag.The shank of syringe needle is provided with the depth of needle holder.
How logical adapter described in this utility model technical solution can be a three-way connector.
How logical adapter described in this utility model technical solution can also be the four-way adapter, and this four-way adapter is provided with the flexible pipe that can be connected with the medicinal liquid bottle.
Groove described in this utility model technical solution and apart 5～15 millimeters of the ends of overlapping letter.
This utility model is owing to having increased sleeve on the basis of ordinary syringe, having led to adapter, apocenosis bag, the groove of lock piston bar, depth of needle holder more, improved piston rod, thereby, can be completely achieved the one man operation, and labor intensity reduces greatly, simultaneously, in entire process therapeutic process, need not change or extract syringe needle to focus, avoid causing pneumothorax and infection, overcome negative pressure in the body, focus can have been handled thoroughly, cure rate is improved greatly.Because whole therapeutic apparatus can be made of plastic, thereby can reduce manufacturing cost greatly, makes it become the one-time treatment device, can avoid not taking place because of sterilization in the repeated use process does not sternly cause the situation of infection.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, suction tube 1, syringe needle 8 are identical with ordinary syringe.Sleeve 2 is merged by two semicircles and forms.Its front end is the connecting device 6 that cooperates with suction tube 1 rear end; Both sides are provided with chute, are convenient to piston rod 14 and slide along chute; The rear end is provided with sleeve shank 3, exerts oneself when being convenient to the one-handed performance suction.Two symmetric grooves 4 are located at apart from the chute place of 5～15 millimeters of sleeve rear end, constitute the negative pressure lock, are used for lock piston bar 14.The front end of piston rod 14 cooperates with suction tube 1, and the power-assisted of rear end handle 5 cooperates with chute and groove 4.Four-way adapter 7 one ends are enclosed within on the nipple of suction tube 1, and front end connects through flexible pipe 10 syringe needles 8, and the lower end is connected with discharging tube 11 through flexible pipe, and the upper end is connected with medicinal liquid bottle 12 through flexible pipe 13.Depth of needle holder 9 can move on shank, and can be fixed on a certain position of shank.Depth of needle holder 9 can be made of the bolt that cooperates with shank, nut.
During use, syringe needle 8 is thrust focus, by 9 lockings of depth of needle holder, utilize piston rod power-assisted handle 5 suction body fluid, be anti-negative pressure, handle 5 can be pulled to groove 4 places, and, handle 5 is admired into groove 4 to right rotation 30～45 degree, allow body fluid under the suction force guiding of suction tube, enter suction tube 1.During discharge opeing, rotating pull handle 5 also makes it break away from groove 4, rotary four-way adapter 7, body fluid is entered apocenosis bag 11, and rotary four-way adapter 7 utilizes flexible pipe 13 and medicinal liquid bottle 12 on this device, with normal saline or medicinal liquid suction suction tube 1, inject focus, this device can be under the situation of not extracting syringe needle 8 repeatable operation, until reaching therapeutic effect.
