Description

Drainage device convenient to puncture

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a drainage device convenient to puncture.

Background

In the operating rooms of various hospitals, doctors often need to place a drainage tube to the wound part of a patient for drainage, before the drainage tube is placed, a hole needs to be formed in the part, adjacent to the corresponding wound, of the skin surface of the patient to be communicated with the corresponding wound, so that the drainage end of the drainage tube to be used penetrates through the hole, then, the wound part of the patient is sewn, and the leading-out end of the drainage tube to be used is exposed and connected to a drainage bag to be used.

The most common method is to open a hole on the skin surface of a patient, generally use a blade to cut, then push inwards from the cutting part through a vascular clamp to separate soft tissues and muscles to form a tube passing channel penetrating through the wound of the patient, and finally, directly pass a drainage tube to be used from the corresponding tube passing channel from outside to inside to the wound of the patient. This solution has a number of disadvantages: firstly, when a blade is used for cutting an incision on the surface of the skin of a patient, the size of the incision is not controlled well, when the incision is too small, a subsequently needed drainage tube is not easy to penetrate, when the incision is too large, unnecessary wound is increased, local tension is reduced, drainage liquid is enabled to seep out of the body along the outer side of the drainage tube, the infection chance is increased, and a long operation scar is left; secondly, the vascular clamp is used for constructing the tube passing channel in a mode of pushing the cutting part inwards, so that the problems of increasing the wound of a patient, increasing the operation steps and prolonging the operation time can be solved.

In order to solve the above disadvantages, the Shenzhen Hospital, Beijing university, filed a utility model patent application named "drainage tube opener" (application number: 2018215475187) in 2018, at 17.9.8, which includes an open-circuit conical head, a guide sleeve adapted to be sleeved with a drainage tube, and an operating handle adapted to be held by hand; the open-circuit conical head, the guide sleeve and the operating handle are all made of stainless steel; the rear end of the open-circuit conical head is detachably connected with the front end of the guide sleeve; the rear end of the guide sleeve and the front end of the operating handle are integrally formed. The drainage tube can be conveniently connected after the scheme is adopted, but in the using process, a circular wound can be formed on the skin by the conical head, the wound is closed for a long time after the drainage tube is pulled out, so that the dressing change times of medical staff are increased, the medical work burden is increased, the economic burden and the psychological burden of a patient are increased, the infection chance is increased, and scars are easily left, which is very unacceptable.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a drainage device convenient to puncture is difficult for leaving the scar when conveniently inserting the drainage tube.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a drainage device convenient to puncture, includes conical head and drainage tube, the head of conical head has flat edge of a knife, and the conical head is made by stainless steel, and the rear end of conical head and drainage tube constitute detachable cooperation.

Compared with the prior art, the utility model discloses there are following technological effect: the conical head of here will puncture is special sets into the flat edge of a knife, and the wound of the skin that cuts during the use is exactly the linear type, and is not circular, and after extracting the drainage tube, the skin of linear type incision both sides can be close to each other because of the effect orientation of tension one side each other, and realization wound healing that can be quick has reduced medical work burden, has reduced patient's economic burden and psychological burden to reduce the chance of infecting, be difficult for leaving the scar.

Detailed Description

The present invention will be described in further detail with reference to fig. 1 to 2.

Referring to fig. 1 and 2, the drainage device convenient for puncture comprises a conical head 10 and a drainage tube 20, wherein the head of the conical head 10 is provided with a flat knife edge 111, the conical head 10 is made of stainless steel materials, and the rear end of the conical head 10 is detachably matched with the drainage tube 20. The special conical head 10 that will puncture sets up into flat edge of a knife 111 here, and the wound of the skin that cuts during the use is exactly the linear type, and is not circular, and after extracting drainage tube 20, the skin of linear type incision both sides can be close to each other because of the effect of tension one side each other, can be quick realize wound healing, has reduced medical care work burden, has reduced patient's economic burden and psychological burden to reduce the chance of infecting, be difficult for leaving the scar.

The structure of conical head 10 has a lot of varieties, and here preferably, conical head 10 constitute including anterior segment 11 and the tail section 12 that has the contained angle, have two sections of contained angle, make things convenient for the doctor to operate, tail section 12 is held when making things convenient for the doctor to puncture, anterior segment 11 is convenient for puncture, after both have certain contained angle, can be convenient dash the puncture from the skin and come out. The flat edge 111 is arranged on the front section 11 of the conical head 10, the plane where the notch of the flat edge 111 is located is perpendicular to the plane formed by the central lines of the front section 11 and the tail section 12, as shown in fig. 2, the flat edge 111 arranged in this way is more convenient to use, and the length direction of the cut notch is perpendicular to the plane where the conical head 10 is located when a doctor operates the puncture tube, so that the phenomenon of tearing the notch cannot occur, the size of the notch is ensured to be stable, the size of the notch just meets the requirement that the drainage tube 20 is worn out, other operations caused by overlarge or undersize of the notch are avoided, and the use is very convenient.

Further, in order to ensure that the puncturing process is smooth, the front section 11 and the rear section 12 of the bit 10 are integrally formed, and the front section 11 and the rear section 12 are in arc transition. After the arc transition is adopted, the conical head 10 can conveniently and smoothly pass through the wound after the wound is cut by a doctor.

The drainage tube 20 and the conical head 10 are detachably matched, before puncture, the drainage tube 20 is firstly fixed at the tail part of the conical head 10, then the conical head 10 punctures the skin and brings the drainage tube 20 out of the wound, then the conical head 10 and the drainage tube 20 are disassembled, part of the drainage tube 20 is left in the wound, and the drainage tube 20 extending out of the wound can be connected with a negative pressure device to drain the wound. The structure of the detachable type is various, and it is preferable that the tail section 12 of the conical head 10 is provided with a cylindrical boss 121, the outer diameter of the boss 121 is matched with the inner diameter of the drainage tube 20, the tail section of the conical head 10 is cylindrical and the outer diameter of the cylindrical boss is matched with the outer diameter of the drainage tube 20, and the drainage tube 20 is inserted into the boss 121 to form the detachable type fit. Through setting up boss 121, the connection and the dismantlement of realization drainage tube 20 that can be convenient.

Furthermore, the peripheral wall of the tube body of the drainage tube 20 at the end far away from the conical head 10 is provided with a plurality of micropores 21, the end is remained in the wound of the patient, and the outflow of the seepage in the wound can be accelerated after the plurality of micropores 21 are arranged.
