Description

Sputum collector fixing device

Technical Field

The utility model relates to a medical auxiliary instrument, in particular to a sputum collector fixing device which is convenient for the operation of reserving and taking sputum specimens of patients with weak expectoration.

Background

Patients with pulmonary infections often need sputum specimens to be left for culture to aid in diagnosis of the condition. For the reasons of illness, the patient who is weak to expectorate needs to use a negative pressure aspirator and cooperate with a disposable sputum collector to carry out the operation of reserving sputum specimens. Because the sputum sucking operation is difficult, patients are not matched, and most patients need to resist, so that the sputum collecting operation is difficult; moreover, the collector needs to be kept in a vertical state all the time, because when the collector is toppled over, sputum in the collector is sucked away by the negative pressure aspirator (sucked to the sputum suction tank). Thus, current operations can only be assisted by a dedicated person to fix the collector in a vertical position; not only consumes manpower, but also influences the working efficiency.

Disclosure of Invention

The utility model aims to overcome the defects in the background art and provide a sputum collector fixing device which can keep the collector in a vertical state when the sputum collecting operation is carried out, so that the working efficiency is improved.

The technical scheme provided by the utility model is as follows:

a sputum collector fixing device comprises a rod piece which can be bent and shaped; the method is characterized in that: one end of the rod piece is connected with a fixer which is used for fixing on a sickbed, and the other end of the rod piece is connected with a clamping jaw which is used for clamping a sputum collector.

The fixer comprises two clamping plates and a push rod for pushing the two clamping plates to open and close so that the fixer can be reliably fixed on a patient bed.

The two clamping plates comprise fixed clamping plates and movable clamping plates; the push rod comprises a core rod and an outer rod sleeved outside the core rod and matched with the core rod through a thread structure; the two ends of the core rod are respectively fixed with the fixed clamping plate and the rod piece, the movable clamping plate is sleeved on the core piece, and the outer rod applies force to the movable clamping plate to enable the movable clamping plate to move on the core piece, so that the two clamping plates are clamped and fixed on the patient bed.

The clamping jaw comprises two clamping jaw sheets which are connected in a hinged mode, and a spring which applies force to the clamping jaw sheets is sleeved on the hinged shaft, so that the two clamping jaw sheets always keep a clamping state, and the clamped sputum collector is prevented from slipping.

A short pipe is fixed at the opening part of the movable clamping plate, and the movable clamping plate is sleeved on the core rod through the short pipe; so as to keep the clamping surface of the movable clamping plate as perpendicular as possible to the axis of the core rod.

The rod piece is a metal corrugated pipe.

The beneficial effects of the utility model are as follows:

1. by using the sputum collector, the sputum collector can be kept in a vertical state all the time, so that the sputum specimen in the sputum collector can not be sucked into the sputum suction tank (the space between the sputum and the suction pipe at the top of the collector in the vertical state is kept, so that negative pressure can not act on the sputum), and the sputum specimen is ensured to be successfully reserved; compared with the prior art, the labor is saved.

2. Because the sputum collector can be always kept in a vertical state, nurses do not need to be distracted during operation, and only need to perform sputum sucking operation at ease; the working efficiency is improved.

3. The fixing device has simple structure and low manufacturing cost; and can be reused, so the investment is less, and the effect is good.

Detailed Description

The utility model is further described below with reference to the embodiments shown in the drawings; the present utility model is not limited to the following examples.

The sputum collector 7 (shown in figure 6) with a conventional structure is a closed cylinder (the diameter is about 3cm and the length is about 8 cm), and the top end of the sputum collector is communicated with two suction pipes 8; the other ends of the two suction pipes are respectively used for sucking the sputum of the patient and are communicated with a sputum sucking tank (the sputum sucking tank is communicated with a negative pressure air source and is in a negative pressure state). Obviously, when sputum is collected in the sputum collector, the collector cannot be toppled over; otherwise, the sputum in the collector in the horizontal state is conveyed to the sputum sucking tank by the negative pressure of the suction pipe, so that the sputum specimen is failed to collect.

For this purpose, the utility model provides a fixing device for the sputum collector.

The sputum collector fixing device shown in fig. 1 comprises a rod piece 5 which can be bent and shaped; one end of the rod piece is connected with a fixer for connecting with a sickbed, and the other end of the rod piece is connected with a clamping jaw for clamping a sputum collector.

The rod piece is a bendable and shapable metal pipe, is a metal corrugated pipe for supporting a desk lamp in the prior art, and can be obtained by outsourcing.

The fixer comprises two clamping plates and a push rod for pushing the two clamping plates to open and close so that the clamping plates can be reliably fixed on the patient bed; the push rod comprises a core rod 4 with external threads on the outer peripheral surface and an external rod 3 sleeved outside the core rod and provided with internal threads (the internal threads can be matched with the external threads). The two clamping plates comprise a fixed clamping plate 1 and a movable clamping plate 2. One end of the core rod is fixed with the fixed clamping plate, and the other end is fixed with the rod piece; the movable clamping plate is sleeved on the core rod through the opening. The outer rod is forced to rotate and simultaneously moves along the axis direction of the core rod, so that the movable clamping plate is pressed against to move along the axis of the core rod; the distance between the movable clamp plate and the fixed clamp plate is changed, so that the fixer can be clamped and fixed on the backrest of the sickbed or the railing of the sickbed.

The clamping jaw 6 comprises two clamping jaw sheets which are connected in a hinged mode (a hinged shaft passes through the hinged lug to be connected in a hinged mode), and a spring (omitted in the figure) for exerting force on the clamping jaw sheets is sleeved on the hinged shaft 9, so that the two clamping jaw sheets always keep a clamping state, and the clamped sputum collector is prevented from slipping. As can be seen, the jaw resembles a daily clip, except that the jaw pieces are designed in an inwardly curved arc to prevent the gripped collector from slipping off.

Furthermore, a short pipe 2-1 (which can be integrally injection molded if an injection molding piece is adopted) is fixed at the opening part of the movable clamping plate, and the movable clamping plate is sleeved on the core rod through the short pipe so as to keep the clamping surface of the movable clamping plate as vertical as possible to the axis of the core rod; when in use, the outer rod pushes the short pipe, and the movable clamping plate can be pushed.

Furthermore, the contact surfaces of the movable clamping plate and the bedstead and the contact surfaces of the fixed clamping plate and the bedstead are respectively provided with anti-slip materials such as rubber sheets, so that the anti-shake device can be used for preventing shake and protecting clamped parts of a sickbed from being damaged.

When the sputum reserving and taking operation is performed by adopting the sputum reserving and taking device, the sputum reserving and taking device only needs to fix the fixer on the backrest or the railing of a sickbed, then open the clamping jaw to clamp the collector, and adjust the rod piece to keep the collector in a vertical state, so that the conventional sputum reserving and taking operation can be started.
