Description

A kind of integral type On Irrigation of Bladder Chemotherapy device

Technical field

The utility model relates to technical field of medical equipment, and in particular to a kind of integral type On Irrigation of Bladder Chemotherapy device.

Background technique

Non- Myometrial involvement bladder cancer accounts for the 70% of initial tumor of bladder, according to risk of recurrence and the difference of prognosis, non-flesh Layer invasive bladder cancer can be divided into three groups: it is low danger, it is middle danger, it is high-risk.The essential therapeutic arsenals of non-Myometrial involvement bladder cancer are Transurethral resection of bladder tumor, after non-Myometrial involvement bladder cancer electrocision, considerable tumor recurrence is since tumour is residual Remaining to cause, the T1 phase bladder cancer of especially middle and high differentiation, Neoplasm residual rate can achieve after electrocision for the first time according to the literature 33.8%-36%.There are very high Postoperative recurrent rate, small portion after non-Myometrial involvement bladder cancer row underwent transurethral resection of bladder tumor Divide patient that can even progress to Myometrial involvement bladder cancer.The simple row underwent transurethral resection of bladder tumor of carcinoma in situ not can solve The problem of postoperative high relapse rate and progression of disease.Therefore, non-Myometrial involvement bladder cancer patients carry out postoperative auxiliary irrigation of bladder Make it is necessary, include On Irrigation of Bladder Chemotherapy and irrigation of bladder immunization therapy.

The postoperative conventional perfusion chemotherapy drug of bladder cancer, average every patient will at least receive the 16-20 above bladder Perfusion therapy, the patient of recurrence then need more perfusion therapy.Because being made at present without dedicated irrigation of bladder device Irrigation of bladder device is exactly common urinary catheter and syringe to be irrigated, but it has the disadvantage in that 1) urinary catheter connects The matching problem of head and conventional syringe injection port, when use, are extremely inconvenient；2) the problem of medical staff makes up a prescription uses syringe It makes up a prescription and needs successively to extract chemotherapeutic agents and water progress mixing preparation, such as first take out a certain amount of chemotherapeutic agents, extract water followed by When being mixed, chemotherapeutic agents can be flowed out from the injection port of syringe to be evaporate into air, causes body to medical staff and patient The damage of the heart；3) it needs to connect intrusion pipe after deployed, also has chemotherapeutic agents and splash volatilization, while being needed after perfusion It is in need when flushing to extract intrusion pipe, it extracts water and reconnects flushing later, troublesome in poeration not say, medical staff in pilot process It is also very unfavorable to its health with patient's multiple-contact chemotherapeutic；Therefore a kind of operation efficient quick, safe and convenient to use is needed On Irrigation of Bladder Chemotherapy device to meet the needs of On Irrigation of Bladder Chemotherapy.

Utility model content

The purpose of the utility model is to overcome the above-mentioned problems in the prior art, provide a kind of integral type bladder filling Infuse chemotherapy device, reasonable in design, operation efficient quick, safe and convenient to use, suitable medical institutions' On Irrigation of Bladder Chemotherapy It uses.

To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions:

A kind of integral type On Irrigation of Bladder Chemotherapy device, is integrally formed structures, including injection device, tee tube, chemotherapy Intrusion pipe and the tee tube that makes up a prescription, injection device front end injection port connect tee tube, the front end interface of tee tube and the first list It is connected to the water inlet of valve, the first check valve front end water outlet connects infusion pipe, infusion pipe range 30-35cm, diameter For 3-4mm, front end is connected with perfusion side opening, the side interface of the tee tube and the water outlet of second one-way valve, and second is single The tee tube that makes up a prescription is connected to the water inlet of valve, the two other interfaces of tee tube that make up a prescription are separately connected first and match with pencil and second Pencil is simultaneously respectively equipped with puncture needle.

Preferably, the puncture needle rear end is equipped with limit pedestal, limits the snap ring and puncture needle that protrusion is provided on pedestal Set connection, Puncture needle sleeve are equipped with non-slip texture.

Preferably, the structure of the injection device is similar with ordinary syringe, injection port, syringe cylinder including front end and Injects piston.

Preferably, first check valve and second one-way valve are conventional one-way valve, and fluid can only be flowed along water inlet, out Mouth of a river medium can not flow back.

Preferably, described first with pencil and second with pipe clamp is arranged on pencil.

The integrally formed integral type On Irrigation of Bladder Chemotherapy device of the utility model, aseptically single sealed package.

The operating method of the utility model are as follows: when On Irrigation of Bladder Chemotherapy makes up a prescription: match pencil with pencil and second for first Puncture needle sleeve pull out and be inserted into chemotherapeutic agents bottle and sterile water bottle respectively, chemotherapeutic agents and sterile water are passed through into second one-way valve Mixing in injection device is reached, the mixed liquor in injection device will not flow back will not flow to intrusion pipe in its natural state, take out When taking, quantitative chemotherapeutic agents can be first extracted, then extracts suitable sterile water and is mixed；In On Irrigation of Bladder Chemotherapy: logical The injects piston for crossing injection device, by mixed liquor by the first check valve reach infusion pipe and reach perfusion side opening fill Chemotherapy is infused, mixed liquor, which will not flow back, to be passed through from second one-way valve；When rinsing after irrigation of bladder, chemotherapeutic agents will be inserted into Puncture needle extract or it is corresponding with pencil block, by another with pencil extract sterile water be rinsed；Perfusion chemotherapy knot On Irrigation of Bladder Chemotherapy device is pressed into predetermined processing after beam.

The beneficial effects of the utility model are: the utility model integral type On Irrigation of Bladder Chemotherapy device, is integrally formed Structure, in On Irrigation of Bladder Chemotherapy operating process, without dismounting combination connection, there is no connect unstable, unmatched to ask Topic, meanwhile, the structure and all parts of integral type reasonably design, and avoid chemotherapeutic agents leakage or contact in operation Air volatilization damages medical staff and patient, and flushing process carries out dismounting extraction without intrusion pipe is extracted after perfusion Rinse sterile water；Also, this device in operation can efficient quick, safe ready chemotherapeutic agents are filled into suitable position It sets, medical institutions is suitble to promote the use of.

Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
